5 Pt.1 Ch.1 Sec.1 Page 5 SECTION 1 CLASSIFICATION PRINCIPLES A. Definitions A 100 General 101 For definition of general terms used in the rules, see Pt.0 Ch.2 Sec.1 A200. A 200 Rules 201 The rules are to be understood as all those rule requirements accepted by the board as basis for classification, which are developed by the Society or adopted from relevant International maritime standards as defined in 202. Interpretations of International maritime standards and standards for ships outside the scope of International maritime standards, as appropriate, are included. 202 International maritime standards, mean international IMO conventions, protocols, codes and resolutions, in so far as their purpose is safety and pollution prevention, excluding articles and regulations dealing with intergovernmental relations, legal and formal aspects. 203 Tentative rules are rules applying to new fields to which the Society reserves the right to make adjustments during a period in order to obtain the intention reflected in the rules. 204 A Guidance note given in the rules is advice which is not mandatory for assignment of class, but with which the Society, in light of general experience, advises compliance, hence, it is for the client to decide whether to apply the Note or not. 205 The HSC Code is the International Code of Safety for High-Speed Craft as adopted by IMO with resolution MSC.36(63). Text quoted from the Code is printed in italics. 206 Det Norske Veritas (DNV) is an autonomous and independent foundation with the object of safeguarding life, property and the environment. DNV undertakes classification and certification and ensures the quality of ships, offshore units and installations, facilities and systems, and carries out research in connection with these functions. DNV operates a world wide network of survey stations and is authorised by more than 120 national administrations to carry out surveys and, in most cases, issue certificates on their behalf. 207 The Society signifies DNV. 208 The Board signifies the Executive Board of DNV through its Chairman who is the President and CEO of DNV. 209 National authorities denotes the Administration of any country of registry. 210 Client means the party having requested classification or having assumed ownership of a classed craft. In cases where owners have authorised another party to operate the craft on their behalf, such party is regarded as the client. 211 IMO is the International Maritime Organization. 212 IACS is the International Association of Classification Societies. 213 A Recognised classification society means a classification society which is a full or associate member of IACS. 214 A Quality audit is a systematic and independent examination to determine whether established work processes and quality systems are adhered to. 215 A Supplier or a Manufacturer, supplies materials, components, equipment and systems to newbuildings to be classed, or to classed craft in operation, whose production is subject to design approval, surveys and testing in accordance with the rules. A 300 Audits 301 A vertical contract audit is an IACS audit which assesses the correct application of the quality system through audit of the process for a specific contract. A contract is the specific agreement between the Society and the client. It defines the extent of services requested by the client, and is concerned with: the classification of ships, both newbuildings and in operation statutory work carried out on behalf of National Maritime Authorities equipment and materials for ships. The IACS QSCS (Quality System Certification Scheme) audit team is responsible for carrying out these audits. B. The Classification Concept B 100 General 101 Classification concept The classification concept comprises the development of independent technical standards for vessels, and the verification of compliance with these standards throughout the vessels life. 102 The rules are aimed at ensuring safety against hazards to the vessel, personnel, passengers and cargo, and against hazards to the environment as a consequence of sea transport. 103 The classification of vessels is performed in accordance with the requirements of the rules and any other standards to which reference is made. 104 Having assigned class, the Society will issue a classification certificate and enter the main particulars and details of class for the vessel in the "Register of vessels classed with DNV". B 200 Entering into force and application of rules 201 Rules and amendments accepted by the board will come into force when decided by the board, normally six (6) months after acceptance. 202 Entry into force and application of those parts of the rules covering International maritime standards are indicated at the beginning of each of the relevant rule chapters. 203 The rules which are in force at the date of the written request for classification, are the basis for the assignment and maintenance of class. Subsequent amendments not made mandatory according to 204 may be made applicable to vessels under construction provided both builder and owner agree to such application. 204 If an amendment is made mandatory to vessels under construction or which have already been assigned class, this will be specially stated. 205 In exceptional cases, where unacceptable service experience and/or theoretical findings clearly show that safety hazards may arise in connection with items covered by the existing rules, the Society may lay down supplementary requirements concerning the assignment and retention of class to maintain the overall safety standard reflected by the rules.

6 Pt.1 Ch.1 Sec.1 Page The Society will consider alternatives found to represent an overall safety standard equivalent to that of the rules. Approval may be revoked if subsequent information indicates that the chosen alternative is not satisfactory. With regard to equivalent alternatives, those parts of the rules covering International maritime standards are to be practised in accordance with procedures agreed by the National Authorities involved. 207 If disputes should arise in connection with the application of those parts of the rules which are adopted from International maritime standards, the texts of the International maritime standards are to prevail. 208 In cases where detailed requirements are not given in the rules, specific solutions or decisions approved by the Society and its surveyors are to be based on the principles of the rules, and are to give a safety standard equivalent to that of the rules. 209 In accordance with 206 the Society may consider the use of reliability methods as a means of documenting compliance to class requirements. B 300 Basis for assignment of class 301 Having assigned a specific class implies that the Society: has been satisfied that the vessel meets the rule requirements for the particular class will, through a system of surveys, verify that the requirements given for retention of class are complied with. 302 Prior to assigning class to an eligible, existing vessel, it is in general to undergo all periodical surveys pertaining to the age and type of the vessel. See Sec.3 A When assigning class to a vessel which has not been built under supervision of the Society, provided the vessel has been built under supervision of another recognized classification society, the Society may on the basis of an overall safety consideration, in connection with a design review and survey, exempt it from rule requirements for the main class. See also When assigning class to a vessel of a series under construction to the classification of, or a design previously accepted by, a recognized classification society, the Society may on the basis of an overall safety consideration, in connection with a design review, exempt it from the rule requirements for the main class, and base the survey on the design approval done by the recognized society. A note to this effect may be included in the Appendix to the classification certificate. 305 When assigning class to a vessel for which the Administration of the flag state undertakes approval and surveys of items covered by the rules, the Society may accept their decisions as basis of assigning class. 306 Classification is based on the assumption that requirements for safety equipment outside the scope of the rules for classification as defined in Sec.2 A200, e.g. requirements for life-saving equipment, navigation equipment and radiocommunication installations, are enforced by the National Authorities in question. If such equipment is not certified by the National Authorities, the certification of the equipment will be enforced by the Society in accordance with the requirements of a recognized SOLAS contracting government or appropriate modified requirements for non-solas vessels. In such cases a written statement will be issued upon assignment of class. Maintenance of the validity of this statement will depend upon satisfactory results of periodical surveys. B 400 Basis for maintenance of class 401 The requirements for retention of class are found in Sec.3 B. In addition, classification is based on the following: Valid statutory certificates The statutory certificates of the applicable international conventions shall be valid at all times, and the surveys prescribed in the conventions shall be carried out within the time windows prescribed. Maintenance of the craft and its equipment It is assumed that the craft, machinery installations and equipment are to be maintained at a standard complying with the requirements of the rules. Installed systems or equipment carried on board in excess of the rule requirements, but otherwise covered by the rules, are either to be maintained in accordance with the rules, or be removed or be disconnected in such way as to ensure that the installed system or equipment cannot be used. Handling of the craft It is assumed that the craft, machinery installations and equipment are to be adequately manned and competently handled. This includes also stowage of cargo, distribution of ballast and bunkers, and speed and navigation in heavy weather. Class conditions regarding the use of the craft are to be observed. B 500 Documentation 501 All information which may influence the judgement, decisions and requirements of the Society for the purpose of classification, is to be made available to the Society. It is the client s responsibility to ensure that such information is brought to the attention of the Society in a timely manner. Information may be made available by submitting documents to the Society or by surveys performed at the clients premises, the craft or the premises of the client s sub-contractors. 502 Documents for information or approval required in each chapter of the rules are to be submitted to the Society. 503 The documentation forming the basis for classification is, at all times, to reflect the true conditions. Revisions of documents are therefore to be submitted to the Society to the extent such revisions may influence decisions and requirements of the Society. B 600 Disclosure of information 601 The Society will not disclose any information received or reports made in connection with classification to any other than those entitled thereto or those having been given the right to receive information by legislation, court decision or by written permission by the owner. The supply of information may take place electronically and on a continual basis, e.g. by online access to the Society s databases. Guidance note: Table B1 indicates which parties will be entitled to various kinds of information. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e The Society will not disclose information that can be considered as the property of another party except when this party s permission is given in writing. 603 Internal communication, notes, calculations etc. produced within the Society in connection with classification will not be disclosed to other parties. 604 Notwithstanding 601 to 603, authorised representatives of the National Maritime Authorities or of the audit team of IACS performing Quality Audits, will upon request have access to such information. These representatives are to confirm in writing that they are not in any manner allowed to reproduce or communicate such information to other parties.

7 Pt.1 Ch.1 Sec.1 Page Notwithstanding 601 and 603 the Society may disclose any information to a police authority upon a written request by the same. 606 The Society may release information on required class and statutory surveys and schedules, delegated statutory certification, overdue surveys and overdue conditions and class suspensions and deletions. Table B1 Disclosure of information Information in question Owner B 700 Limitation of the Society s responsibility 701 The classification service is performed on the basic assumption that other parties involved (building yard, designers, manufacturers, sub-contractors, ship owners, etc.) fulfil their individual obligations. The classification service is not performed in substitution of other parties role or obligations. Nothing contained herein or in any certificate, report or document issued in connection with or pursuant to these rules, shall relieve any designer, engineer, builder, manufacturer, shipyard, seller, supplier, owner, operator or other parties from any obligations or consequences of default whatsoever. In particular, compliance with the rules does not imply acceptance or commissioning of a craft. This is the exclusive responsibility of the owner.

It is the responsibility of the owner to maintain the condition of the craft as required by the rules between surveys. B 800 Vertical contract audits and audits by National Maritime Authorities 801 For the purpose of conducting vertical audits performed by the audit team of IACS, and audits performed by the National Maritime Authorities of the flag state, access is to be provided to the craft and/or to the premises of manufacturer or shipbuilder, as appropriate.

8 Pt.1 Ch.1 Sec.2 Page 8 SECTION 2 SCOPE OF RULES AND CLASS NOTATIONS A. Scope of Rules A 100 General 101 The rules define acceptance criteria for design, construction, survey and testing of high speed, light craft and naval surface craft constructed in steel, aluminium or fibre reinforced composites, their machinery installations, systems and equipment, applicable to the newbuilding and operations phase. 102 International maritime standards covered by the rules include: International Code of Safety for High-Speed Craft (HSC Code) May 1994, as amended. For principles of application of the HSC Code see Pt.0 Ch A light craft is defined as a craft with a full load displacement not more than: L B = maximum permissible displacement (tonnes) = overall length of the underwater watertight envelope of the rigid hull excluding appendages, at or below the design water line in the displacement mode with no lift or propulsion machinery active (m) = waterline breadth at L/2 (m). Craft with displacements in excess of the above requirement shall be classified in accordance with additional requirements to strength and watertight integrity as stipulated in each individual case. 104 For light craft the freeboard is provided by the reserve buoyancy represented by the volume of the hull above the waterline up to the bulkhead deck at the maximum operational displacement of the craft. The reserve buoyancy shall not be less in percent than given in the table for the various service restrictions: 105 High speed craft is defined as a craft capable of a maximum speed in knots equal to or exceeding: V = ( 0, 13 L B) 1, 5 (tonnes). R0 R1 R2 R3 R4 R V , = = the speed (knots) = the displacement corresponding to the design waterline (tonnes). Guidance note: The above criteria is in compliance with the application for the IMO HSC Code. The factor is adjusted only for the alternative units. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e High speed and light craft shall, in addition to 103 and 104 have a maximum speed of not less than 25 knots. Guidance note: IMO res. A.373(X) Code of Safety for Dynamically Supported Craft, the DSC Code, requires a maximum speed of F n > 0,9. This requirement is not covered by this edition of the rules and is not applicable to existing craft under the DSC Code. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e Craft complying with the definition of both light craft and high speed craft and having speed above 25 knots, shall be in compliance with the HSC Code, unless otherwise required by the service notation. 108 A classification certificate will be issued for the craft, see Sec.3 A. Main particulars and details of class for the craft will be entered in the "Register of vessels classed with DNV". A 200 Rule parts 201 This part of the rules (Pt.1) covers all craft, newbuildings as well as craft in operation. 202 The rules for main class which apply to all newbuildings are given in Pt.2, Pt.3 and Pt.4, and include those parts of the international maritime standards which are relevant to high speed and light craft in general. 203 The rules for additional class notations applicable to newbuildings, including those parts of the International maritime standards not covered by main class, are given in Pt.5 and Pt.6. Additional class notations apply to; craft which have been designed to perform a special service special equipment and systems not covered by the main class special features not covered by other notations. All craft shall satisfy the requirements of one special type notation given in Pt The rules for craft in operation are given in Pt.7 and cover also parts of international maritime standards applicable to operation. A 300 Rule particulars 301 The rules for main class give requirements for the hull, machinery installations and equipment with respect to strength and performance of the following main functions: weathertight and watertight integrity stability, survival capability power generation propulsion steering fire safety drainage and bilge pumping ballasting and cargo pumping anchoring and mooring safety management systems. The requirements are aimed at safety against hazards to the craft, personnel and environment and reliability in the performance of the above main functions and their related auxiliary functions. 302 For certain machinery installations, regardless of their contribution to the main functions stated in 301, the rule requirements for main class will apply. Such installations comprise: electric power plants gravity tanks or pressure vessels and associated piping systems for: toxic fluids fluids with temperatures above 220 C boilers and steam piping systems pressure vessels and associated piping systems for compressed gases where:

9 Pt.1 Ch.1 Sec.2 Page 9 For vessels with service area restrictions ranging from R3 to R5, further modifications of requirements may be considered in each case. The notation R6 will not allow any reduced requirements compv 150 ( knm) p = design pressure (kn/m 2 ) V = pressure vessel volume (m 2 ) firing and combustion installations other installations stated in the rules for main class. A 400 Assumptions 401 The design may be based on specified reductions in speed versus sea state (wave height) or a limited vertical acceleration of the craft. Also special limitations as to trim and stability, manoeuvring in narrow waters and handling of the craft may be given. Such limitations are to be specified in an operating manual. Guidance note: A high speed and light craft should normally be provided with adequate information and guidance in a technical manual consisting of an operating manual and a maintenance manual. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e The rules are based on the assumption that significant dynamic excitation of major orders from propeller and machinery will not fall close to any natural frequency of the hull, girder and its main structural members. B. Class Notations B 100 General 101 All craft found to satisfy the requirements in Pt.1, Pt.2, Pt.3 and Pt.4 will be given a main class consisting of a construction symbol, a main character of class, and a high speed and/or light craft notation, e.g.: 1A1 LC 1A1 HSLC Craft with the LC notation will have the service restrictions in nautical miles reduced by the factor: V (knots) The LC notation confirms that the craft is of light weight displacement in compliance with A103. This class notation does not confirm compliance with the HSC Code as requirements related to high speed are not included. The HSLC notation confirm that the craft is of light weight displacement and is a high speed craft in compliance with the HSC Code when one of the type and service notations Passenger, Car Ferry A (or B or C) or Cargo is added, unless otherwise required by the service notation. 103 Craft found to satisfy requirements in Pt.5 will be given additional class related to special service and type of vessel e.g.: 1A1 LC Passenger 1A1 HSLC Passenger 104 A naval surface craft complying with the applicable requirements of this chapter will be assigned the class notation: 1A1 LC Naval provided the displacement when fully loaded is not more than: ( 0.16 L B) Craft also found to satisfy requirements in Pt.6 may be given additional class notations related to special systems and equipment. 106 In addition to the class notations, the Society will provide information related to the craft through register information. B 200 Construction symbols 201 The symbol will be given to craft built under the supervision of DNV. 202 The symbol will be given to craft built under the supervision of a recognised classification society and later assigned class with DNV. See Sec.1 B303. B 300 Main character of class 301 The notation 1A1 will be given to craft with hull, machinery and equipment found to be in compliance with the rule requirements stated in Pt.1, Pt.2, Pt.3 and Pt The notation 1A2 will be given to craft found to meet the rule requirements, where by reason of special design, materials, general condition and/or age, it is considered necessary to stipulate shorter intervals between surveys than those which are normally required for vessels with the notation 1A1. B 400 Service area restriction notations 401 High speed, light craft and naval surface craft will be given a service area restriction notation in accordance with Table B1. Service area restrictions, ranging from R0 to R6, given in nautical miles and representing the maximum distance from nearest harbour or safe anchorage, are given in Table B1. For the various service notations the restrictions are related to the zones, areas and seasonal periods as defined in the International Convention on Load Lines, Annex II, see Appendix A. Table B1 Service restrictions, general Condition Notation Winter Summer Tropical Ocean None 1) 1) 1) Ocean R ) 1) Ocean R Offshore R Coastal R Inshore R Inland R Sheltered R Guidance note: 1) Unrestricted service notation is not applicable to craft falling within the scope of the HSC Code, i.e. service and type notations Passenger, Car Ferry or Cargo. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e--- The service area restrictions as related to the given service area notation will be included in the "Appendix to the classification certificate". 402 Modified requirements related to the various service area notations are given in the relevant sections of the rules. The modifications will affect: design hull girder loads design pressures on shell, weather decks, superstructures and deckhouses anchoring and mooring equipment arrangement closing appliances reserve buoyancy emergency power.

10 Pt.1 Ch.1 Sec.2 Page 10 pared with R5, but may be assigned in special cases. Guidance note: In the SOLAS convention Reg. II-1/1.4 the following is given: The Administration of a state may, if it considers that the sheltered nature and conditions of the voyage are such as to render the application of any specific requirements of this chapter unreasonable or unnecessary, exempt from those requirements individual ships or classes of ships entitled to fly the flag of that state which, in the course of their voyage, do not proceed more than 20 miles from the nearest land. ---e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e The service area restriction will be given as a class notation related to the service and type notation e.g.: 1A1 HSLC R1 Passenger where service restriction distances corresponding to R1 will be stated in the "Appendix to the classification certificate". 404 Maximum possible service restrictions related to each special type of vessel is given in Pt.5 for each special type notation. As far as this service restriction may impose more severe restrictions than those represented by R0 to R5, this will be given as an addition to the special type notation, e.g.: 1A1 HSLC R1(65, 130, 190) Passenger where the term (65, 130, 190) represents the maximum distances from nearest harbour or safe anchorage in winter, summer and tropical load line zones, respectively. This will be stated in the "Appendix to the classification certificate". B 500 Service and type notations 501 Craft arranged and/or strengthened for a special service and found to be in accordance with relevant requirements in Pt.5 will be given corresponding additional class notations: Passenger (see Pt.5 Ch.1) Car Ferry A (or B or C) (see Pt.5 Ch.2) Cargo or Cargo A or Cargo B (see Pt.5 Ch.3) Crew (see Pt.5 Ch.4) Yacht (see Pt.5 Ch.5) Patrol (see Pt.5 Ch.6). Table B2 Naval Vessels (Pt.5 Ch.14) Naval Naval Support Naval Support (.) (.) may contain any of the elements as specified below: hull = additional naval requirements for arrangements as given in Pt.5 Ch.14 Sec.2, loads in Pt.5 Ch.14 Sec.3 and hull strength in Sec.4 have been applied. stab = naval requirements for stability as given in Pt.5 Ch.14 Sec.5 has been applied system = additional naval requirements for piping as given in Pt.5 Ch.14 Sec.6, machinery in Pt.5 Ch.14 Sec.7, electrical in Pt.5 Ch.14 Sec.8, control and monitoring in Pt.5 Ch.14 Sec.9 have been applied. fire = additional naval requirements for fire safety as given in Pt.5 Ch.14 Sec.10 or 11 have been applied. evac = naval requirements for safe evacuation as given in Pt.5 Ch.14 Sec.12 have been applied. radhaz = naval requirements for radiation hazards as given in Pt.5 Ch.14 Sec.13 have been applied. emc = naval requirements for electromagnetic compatibility as given in Pt.5 Ch.14 Sec.14 have been applied. sam = naval requirements for storage rooms for ammunition as given in Pt.5 Ch.14 Sec.15 have been applied. F-naval additional fire protection, as given in Pt.5 Ch.14 Sec.11 Sub-section I, has been applied B 600 Equipment and systems notations 601 Vessels having special equipment or systems found to satisfy relevant requirements in Pt.6 will be given a corresponding additional class: HELDK, HELDK-S, HELDK-SH or HELDK-SHF (See Pt.6 Ch.1) E0 (see Pt.6 Ch.3 ) ICS (see Pt.6 Ch.5) NAUT (see Pt.6 Ch.8) ELT (see Pt.6 Ch.9) NBC (see Pt.6 Ch.10) HMON (see Pt.6 Ch.11 ) N, SV, MV (see Pt.6 Ch.12) B 700 Register information 701 The register provides information regarding special features. The information will be entered in the register, but the corresponding features will be subject to periodical surveys only to the extent possibly covered by the craft s class notations. 702 A complete list of class notations and their explanations will be given in the current issue of the "Register of vessels classed with DNV." B 800 National regulations 801 A craft trading under its own flag in domestic waters, or between neighbour states upon agreement between such states, may be assigned class based on the flag state requirements for domestic service instead of those rule requirements pertaining to assigned class notations. The assigned class shall be the class notations and service restrictions with the least possible deviation from the rule requirements. 802 Deviations from the rule requirements will only be accepted with respect to statutory regulations approved by the flag state as mentioned in 801 and not for the structural strength, machinery installations including steering appliances, and electrical systems and equipment covered by the main class. 803 The flag state whose domestic requirements are being accepted (as per 801) shall be indicated, by using lower-case letter codes in accordance with ISO standard 3166, in parentheses after the service restriction notation (e.g. R2(nor), should the flag state be Norway or (usa) should the flag state be U.S.A. etc.). 804 A memo for owners (MO), containing information about the assumption for the service restriction notation, will be issued in addition to the class related information contained in the "Appendix to the classification certificate".

Assignment of Class A 100 Request for classification 101 A request for classification of a craft is to be submitted in writing by the client. A 200 Requirements for workshops and yards 201 Builders unknown to the Society are to demonstrate their capability to carry out fabrication of adequate quality in accordance with the rules before construction is started. 202 Welding of important structures, machinery installations and equipment is to be carried out by approved welders, with approved welding consumables and at welding shops accepted by the Society. Requirements for approval of welding shops, welders, manufacturers of welding consumables, welding consumables and welding procedures are given in the rules (see Pt.2 Ch.3). 203 During fabrication and construction work, the Society s surveyors are to have safe access to the works at all reasonable times, insofar as the work affects classification. The client is to ensure, through contracts with the parties concerned or otherwise, that such access is possible, and that the Society is notified as to when and where the surveyor s attendance is needed. 204 The following general documentation from the builder (workshop and yard) and from subcontractors (as specified in 301) is to be submitted when requested by the Society: outline specification for the craft list of subcontractors to the building yard list of subcontractors to the manufacturer of products to be delivered, if applicable. A 300 Requirements for manufacturers 301 Manufacturers of materials, components and equipment of categories not covered by 200 are to be considered for approval according to programmes and criteria established by the Society, as applicable. 302 Any required quality control of materials, components and equipment, is to be traceable and documented in writing. Further, it is to be carried out by qualified personnel at facilities and with equipment suitable for that control. A 400 Requirements for suppliers of services 401 Suppliers providing services on behalf of the owner, such as measurements, tests and maintenance of safety systems and equipment, the result of which may form the basis for the surveyor s decisions, are to be approved by the Society, according criteria established by the Society. Where surveyors use such services in making decisions affecting statutory certifications, the suppliers are subject to approval by the Society, where the Society is so authorised by the relevant flag Administration. For such services the Society may accept approvals done by the flag Administration, or duly authorised organisations acting on behalf of the flag Administration. A 500 Requirements for calibration of equipment 501 Measuring and test equipment used in services by manufacturers, builders, repairers or owners, the result of which may form the basis for the surveyor s decisions, is to have a calibration status or an appropriate accuracy to the surveyor s satisfaction. A 600 Plan approval 601 The builder or manufacturer shall submit the following documentation, as specified in the applicable chapters of the rules, and according to documentation lists supplied by the Society upon receipt of class request, before production commences: a) Plans and specifications required for approval, in triplicate, including one copy for each sister craft, as applicable. Moreover, the Society may specify alternative or additional requirements. b) Corresponding technical descriptions, calculations and data, including material specifications. Any documents submitted for re-approval are to be specially marked to identify the revised parts. The builder, with which the Society has the classification contract, is responsible for co-ordinating that plans and other documents are submitted, and for distributing any approval comments that may have been given. 602 When a craft, which is not built under supervision of the Society, is to be classified, the information required in 601 is, in general, to be submitted for approval. The extent of documentation approval for a craft, which is classed, or which was previously classed, with another recognised classification society, will be decided upon in each case. 603 Plans that have been found to comply with the rule requirements will be provided with a statement of approval. Conditions and limitations of the approval may be stated on the plans returned with the statement of approval, or in the accompanying letter of approval. 604 The approval may be revoked at any time if subsequent information indicates that the design solution was contrary to the rule requirements or intentions. 605 The English language shall be used in plans and specifications submitted for approval. The possibility of using the local language shall be agreed upon in each case. 606 When plans and documents are submitted as electronic files, the format and transfer method shall be agreed upon in each case. A 700 Survey 701 When a vessel is built under the supervision of the Society, the Society will verify: that the construction and scantlings comply with the rule requirements and the approved plans, and that the required materials are used that the materials, components and systems have been certified in accordance with the rules that the work is carried out in compliance with the applicable rules and with good engineering practices. IACS "Shipbuilding and Repair Quality Standard - Part A" is regarded as an example of a standard regarding hull structures describing such good engineering practices that satisfactory tests are carried out to the extent and in the manner prescribed by the rules. Supervision is to be carried out at the building yard and/or the sub-suppliers at the discretion of the Society, which also decides the extent and method of control.

12 Pt.1 Ch.1 Sec.3 Page The verification method applied by the Society at the building yard or at the manufacturers will normally be based on visual inspections and tests. The Society may base its verification on audits of an accepted quality system implemented at the yard or at the manufacturer in combination with an agreed manufacturing survey arrangement. 703 When a craft, which has not been built under the supervision of the Society, is to be classified, the Society will carry out surveys to confirm: that the design and scantlings comply with the approved plans that the material, components and systems are in accordance with the rules that the workmanship is in compliance with the applicable rules and with good engineering practices. Functional tests are to be carried out as deemed necessary by the Society. 704 For craft built under the supervision of another recognised society the requirements of 703 will normally be considered as complied with for the main class. 705 When an existing craft is to be classified it is in general to undergo all periodical surveys pertaining to the age and type of the craft. Craft previously classed by a recognised society will, as a minimum, be subject to an annual survey, in accordance with Pt.7 Ch.2, with special emphasis on the craft s general condition and including thickness measurements for craft of age exceeding 10 years. In addition, any periodical surveys due with the previous society are to be carried out. If the age of the craft exceeds 20 years, it is to undergo a renewal survey irrespective of when this is due with the previous society. A 800 Functional and structural testing 801 A test programme is to be prepared by the builder to the satisfaction of the surveyor. The programme is to specify systems and components to be tested and testing procedure. The programme is to include sea trials of the craft with machinery and equipment installed. For new designs a comprehensive full-scale prototype testing programme is to be performed, including measurements of hull girder stresses and accelerations. 802 The tests are to give evidence as to satisfactory operation in accordance with the rules. When testing the control and safety system, failure modes are to be simulated as realistically as possible. 803 Unless otherwise agreed, the testing required by the rules is to be carried out in the presence of a surveyor. Data are to be recorded according to the test programmes and as considered necessary by the surveyor. A 900 Certification of materials, components and systems 901 The scope of classification includes certification of materials, components and systems intended for the craft. The applicable chapters of the rules define the extent of the certification that is needed for classification. The objective of the certification is to ensure that materials, components and systems used in craft to be classed by the Society conform to the rules and other standards within the framework of the rules. The certification is a conformity assessment normally including both design and production assessment. The production assessment includes inspection and testing during production and/or of the final product. 902 The design assessment of the materials, components and systems shall either be on a case by case basis or follow the procedure for type approval. 903 When the case by case procedure is used, documentation of the design shall be submitted for assessment for every application as required in the applicable chapters of the rules. A design assessment letter or design verification report shall be issued by the Society when compliance with the requirements for the design for the actual application is confirmed. 904 When the type approval procedure is used, documentation of the design and the results of type testing as required in type approval programmes and the applicable chapters of the rules, shall be submitted for assessment. A type approval certificate shall be issued by the Society when compliance with the requirements for the design is confirmed. The type approval certificate has a validity of 2 or 4 years depending on type of material, component and system. 905 The production assessment of materials, components and systems shall either be on a case by case basis or on the basis of an agreed Manufacturing Survey Arrangement (MSA). 906 When the case by case procedure is used, the survey and testing shall be performed on the basis of approved design documentation for the actual application and as required in the applicable chapters of the rules. Compliance with the approved design documentation and the requirements shall be documented through certificates as required in the applicable chapters of the rules. 907 When the production assessment is based on an MSA, the survey and testing shall be performed on the basis of approved design documentation and in accordance with requirements and procedures laid down in the MSA. Compliance with the approved design documentation and the requirements shall be documented through certificates as specified in the MSA or as required in the applicable chapters of the rules. 908 Certification of materials, components and systems shall be documented by the following types of documents: 1) Det Norske Veritas Product Certificate (NV): A document signed by a surveyor of the Society stating: conformity with rule requirements that tests are carried out on the certified product itself that tests are made on samples taken from the certified product itself that tests are performed in presence of the surveyor or in accordance with special agreements. 2) Works Certificate (W): A document signed by the manufacturer stating: conformity with rule requirements that tests are carried out on the certified product itself that tests are made on samples taken from the certified product itself that tests are witnessed and signed by a qualified department of the manufacturers. 3) Test Report (TR): A document signed by the manufacturer stating: conformity with rule requirements that tests are carried out on samples from the current production. The applicable chapters and sections of the rules will specify which of the above mentioned documentation will be required.

13 Pt.1 Ch.1 Sec.3 Page 13 Guidance note: For guidance regarding spare parts for ships in operation, see Pt.4 Ch.2 Sec.2 A e-n-d---of---g-u-i-d-a-n-c-e---n-o-t-e Where the rules require Works Certificate (W) or Test Report (TR), the surveyor may at any time require tests to be carried out in his presence and/or check elements of the quality control in operation. 910 For identification and traceability, certified products are to be stamped in accordance with the marking given in the product certificate and as specified by the applicable chapters of the rules. 911 For certain components and systems as defined in the applicable chapters of the rules, the certification may be based on defined internationally recognised standards and certification schemes that cover the overall quality, safety and environmental standard of the rules. Compliance with the requirements of the standard shall be documented as required by the standard. 912 To ensure an efficient, cost effective and correct certification process, a "General certification agreement" is normally to be established with manufacturers delivering NV certified products. The "General certification agreement" may be part of a Manufacturing survey arrangement. The "General certification agreement" is to include information on the procedures for design and production assessment and on transfer of information and experience between the manufacturer and the Society. A 1000 Manufacturing Survey Arrangement 1001 When the procedures and processes of a building yard s or a manufacturer s quality system meet the quality, safety and environmental standard of the rules, a Manufacturing Survey Arrangement (MSA) may be established with the yard or the manufacturer as an alternative to the verification and production assessment described in the applicable rule chapters The agreed MSA is to be described in a document stating the requirements, scope, acceptance criteria, documentation and the roles of the Society and the yard or the manufacturer in connection with the production assessment When it is agreed through an MSA that the majority of the required surveys and tests are being completed without the presence of a surveyor, it is conditional upon the manufacturer that he has in operation a quality system certified by an accredited certification body to ISO 9002, or equivalent When establishing an MSA, an initial assessment of the manufacturer s ability to control product quality and to comply with the scope, requirements and criteria laid down in the MSA shall be performed. The extent and frequency of periodical assessments of the manufacturer shall be included in the MSA An MSA is normally given a validity of 4 years. When the MSA is based on a certified quality system, the MSA automatically becomes invalid if the quality system certification is no longer valid. A 1100 Type approval 1101 Type approval is a procedure for design assessment. Type approval can be applied to a: product group of products system. This procedure should normally be used for design assessment of standard designs The type approval procedure will normally consist of the following elements: design approval type testing issuance of type approval certificate. The type approval procedure used by the Society is described in Standard for Certification No For certain products and systems as defined in the applicable chapters of the rules, type approval is sufficient for confirmation of product quality, i.e. production assessment is not required For certain products and systems as defined in the applicable chapters of the rules, type approval is a mandatory procedure for design assessment For products and systems manufactured for stock, type approval is to be the normal procedure for assessment of design For type approved products, where the basis for approval are the rules of the Society, plans and technical descriptions of the product need not be submitted for approval for each craft unless otherwise stated as a condition on the type approval certificate. In such cases only the arrangement or system plans, interface plans and those plans mentioned on the type approval certificate are to be submitted for approval. A 1200 Acceptance of control by National Authorities 1201 In cases where the Administration of a flag state reviews plans, carries out type approval, and surveys the craft and/or its components and equipment in accordance with the rule requirements, the Society will normally accept the approval and survey by the flag administration as basis for assignment of class. Necessary documentation including copies of approved plans, reports and other particulars approved by the National Authorities, have to be submitted. A 1300 Certificate of interim class 1301 When the surveyor is of the opinion that the requirements corresponding to the class in question have been met, he will document the completion of the building supervision by issuing the certificate of interim class, which is valid until the administration of the Society has confirmed the class and issued the classification certificate At the discretion of the surveyor the building supervision may be considered to be completed with some minor items unverified, provided Conditions of Class (see B800) are issued to the effect that the remaining work, surveys or other measures are to be completed within a specified time. At the same time the surveyor will document the completion of the newbuilding supervision by issuing the certificate of interim class as indicated in In case of classification of an existing craft not built under the supervision of the Society, or classification of an existing craft previously classed by the Society, the surveyor will issue the certificate of interim class when he is satisfied that the applicable requirements have been met. A 1400 Classification certificate 1401 When the administration of the Society has examined the surveyor s report and is satisfied that the requirements corresponding to the class in question have been met, the class will be assigned and a classification certificate will be issued. Provided the requirements for maintenance of class will be complied with, and unless the class has been withdrawn in writing at an earlier stage, the classification certificate will be
