19 Diverse Staff

20 HSE-MS SEPCO Brown Field Projects Operating Platform Systems Damaged Assignment and Completion of HSE Critical Activities Incident Response

21 Offshore Tools Basic Training HSE Orientations Over 1,300 personnel attended orientations covering HSE expectations, roles and responsibilities of each individual concerning the work processes and HSE resources available on site. Fatigue Awareness Nearly 900 personnel attended training sessions on fatigue awareness, recognition, and preventative measures. Fall Protection & Fall Rescue Over 300 personnel attended training on fall protection/prevention with 134 of these receiving additional training in fall rescue techniques.

22 Offshore Tools Process BBSM Process Nearly 2,600 BBSM observations were conducted by the workforce and project management. These were tracked, trended and discussed during safety meetings and toolbox talks to communicate at risk behaviors and areas for improvement. Additionally, the BBSM cards identified 365 unsafe conditions. Permit to Work System The SEPCO Permit to Work System was used to manage work tasks and help ensure compliance with guidelines adopted for simultaneous operations. Over 2,600 permits were developed in the course of the repair work on the TLP.

23 Offshore Tools Continuing Education Daily Safety Meetings - Safety meetings were conducted twice daily to recap workplace HSE issues, best practices and discuss hazards associated with upcoming tasks. Formal Weekly Safety Meetings Formal structured safety meetings were conducted weekly for both day and night crews. These meetings discussed HSE trends, HSE milestones and targets, recent incidents, workplace audit results and work scope. These forums were also used to formally recognize proactive HSE intervention.

24 Offshore Tools Audits Management Walkthroughs Over 75 Management Walkthrough audits were conducted and documented. This provided line management an opportunity to observe hazards and worksite conditions first hand. It also was a good demonstration of Management s commitment to the HSE effort. JSEA & Formal Job Site Audits Nearly 550 JSEA and Job site audits were conducted to identify gaps in the hazard analysis processes. Results were documented, tracked, trended and used as a coaching tool for area Foremen to promote continuous improvement.
