1 Preventing Major Accident Events in Construction

2 Major Accident Prevention (MAP) Program Current Industry Performance & Practices Major Accident Prevention (MAP) Concept Case Study MAP in Practice Future Application Line of Sight MAE hazard management 2

3 Current Industry Performance Worker Fatality Statistics IOGP 2014 Most Common Causes Transport HV / LV (13%) Hit by moving plant / equipment (33%) % fatalities occurred onshore 4 fatalities associated with Australian project activities (shipyards / onshore) Dropped Objects (11%) Fall from Heights (11%) 3

4 MAP Concept A risk based methodology to identify MAE s applicable to construction activities; A corporate register of performance standards (MAE Mandatory controls) for each MAE hazard; A process for supervisors to systematically verify MAE mandatory controls are applied in the field; and A reporting and assurance program line of sight MAE risk management. 4

5 Mapping MAE and Activities Offshore Safety Case MAP Framework Safety Management System Critical Controls MAE Mandatory Controls MAP (Mandatory Control Register) Facility Description (design & control systems) Major Accident Event Analysis (control system failures) Construction Activities (work scopes) Major Accident Event Analysis (Mechanisms of energy release) 5

6 Applying MAE Hazard Management to Project Activities Clough MAE Assessment Matrix Clough MAE Hazard Register Actions to control MAE hazards defined, understood and managed on a daily basis. Map MAEs against Activities Review MAE Hazard Control Sheets Develop Project control ACTIONS Project MAP Register Review & report MAP compliance weekly 6

7 Applying Bow Tie Analysis Understanding MAE Hazards (Applying Bow Tie Analysis) Lifting Operations Example Health Safety Security Environment MAE s Lifting Device Instability Contact with Structure Lifting over Live Services Dropped Load RISK EVENT Lifting Operation accident ACTIVITIES Site Preparation Pipe laying Logistics Work Scopes Specific Control Actions 7

8 Assessing Project MAE Hazards Define MAE that Apply to Work scope MAE Hazard Register Project A CLOUGH ACTIVITIES MAJOR ACCIDENT EVENT HAZARD ACTIVITIES RELEVANT TO PROJECT Working at Height Working in Confined Space Lifting Operations Stored Energy Fire & Explosion Excavation Plant and Mobile Equipment Equipment Driving Vehicles Personnel Transfers Hazardous Materials & Chemicals Logistics YES Fabrication NO Earthworks YES Siteworks YES Concrete YES Piling Onshore YES Piling Offshore YES YES Land Pipelines NO Roadworks YES Railworks NO 8

9 Field Verification and Assurance MAP Checks verify Mandatory Controls Implemented Select MAP Checks Lifting Ops Working at height Stored Energy MAP uses incident analogue events as a communication tool for supervisors Supervisor Field Check Design review Equipment certifications Field inspections Observations MAP is used as the basis of incident investigations Assurance checks by senior site management confirm integrity and quality of MAP checks My guys are much more aware of the hazards, as we use the MAP checks as part of pre-starts. The team now get it and remind me of the things we need to check before starting a lift Lifting Supervisor Mandatory Controls implemented All controls confirmed and implemented Commence work

10 Applying MAE Hazard Management to Project Activities Clough MAE Assessment Matrix Clough MAE Hazard Register MAP is the repository for MAE learnings from analogue events, incidents, hazards and feedback. Map MAEs against Activities Review MAE Hazard Control Sheets Develop Project control ACTIONS Project MAP Register Reporting and MAP compliance Incidents and Hazards Lessons Learned Supervisor Feedback Assurance Audits 10

11 MAP in Action Jetty Project 11

12 Jetty Project HSE Performance High Potential Incidents Lifting operations - average 5 lifting related incidents per month - 4 HPI s including an LTI Stored Energy - Shattered cutting disc, - 3 HPI s over 4 months Decision taken to implement MAP 4 months of project left. 12

13 MAP Checks Rigorous application of MAP Checks Focus on major risk activities:? Working over Water (MAE-MOP-001)? Moving / swinging loads (MAE-MOP-003)? Dropped loads (MAE-LOP-004)? Marine personnel transfer (MAE-MOP-003) Assurance completed by project leaders Quality monitored & feedback by HSE Advisors Jetty Project MAP Checks Demobilisation commenced Jan-15 Feb-15 Mar-15 Apr-15 MAP Check Target 11 checks / month MAE MOP-007 MAE-MOP-006 MAE-MOP-003 MAE-MOP-001 MAE-WAH-003 MAE-WAH-002 MAE-WAH-001 MAE-LOP-004 MAE-LOP-003 MAE-LOP-002 MAE hazards verified in the field 13

14 MAP Results MAP implementation had immediate impact Zero HPI s in final four months of project All lifting incidents reduced from average of 5 per month to zero Key success factors included: Led by Construction Manager & Supt Consistent application of MAP Checks quality of verifications by supervisors in the field Improvement in quality / availability of supporting information Leadership review of MAP Hazard profile target high risk activities Demobilisation commenced Delivering results 14

15 From Concept to Reality A MAE hazard management system for construction which delivers: A risk based methodology to identify MAE s applicable to construction activities; A corporate register of performance standards (MAE Mandatory controls) for each MAE hazard; A process for supervisors to systematically verify MAE mandatory controls are applied in the field; and A reporting and assurance program line of sight MAE risk management. MAP is valued by frontline supervisors now able to directly prevent MAE s and keep their people safe 15

16 Achieving Line of Sight MAE Management MAE Hazard Applied to Activities Mandated ACTIONS Formal Project Assessment Project MAP Register Lessons Learned Weekly Compliance Reporting Incidents and Hazards External Verification of actions Every MAE hazard known, understood & managed 16

17 Future Application MAP concept can be applied to most work activities Currently Clough is expanding application to brownfields and other resource sectors 17
