THE THEVENARD ISLAND SAFETY CASE- APPROACHES USED TO DEVELOP AND IMPLEMENT A SAFETY CASE FOR AN EXISTING FACILITY

Abstract

As a proactive step in the management of Health and Safety, WAPET as operator on behalf of its Joint Venture Participants, considered it good practice to develop a Safety Case for the onshore component of the Thevenard Island facilities and operations along with the legislated offshore requirement. The development of the Safety Case utilised a process which incorporated qualitative assessment of risk, quantification of key risks and assurance that risks were as low as reasonably practicable. For this existing facility, the process clarified the quality of the existing hazard controls and provided an opportunity to make significant improvements.

The process used ensured a high degree of employee and Regulator involvement throughout the Facility Description, Safety Management System and Formal Safety Assessment components of the Safety Case. This has achieved a high degree of awareness among the operations staff of risk management techniques. These techniques are now being applied routinely in the management of the operation.
