Decommissioning Plans for Fixed Offshore Platforms: A Brief Revision

Evaluating alternatives for decommissioning California's offshore oil and gas platforms.

This paper introduces a series of 6 additional papers in this issue that describe an in-depth analysis of options for decommissioning oil and gas platforms offshore southern California. Although current leases require lessees in both state and federal waters to completely remove all production facilities and restore the seafloor to its pre-platform condition, other options have emerged since th...

A multi-attribute decision analysis for decommissioning offshore oil and gas platforms.

The 27 oil and gas platforms off the coast of southern California are reaching the end of their economic lives. Because their decommissioning involves large costs and potential environmental impacts, this became an issue of public controversy. As part of a larger policy analysis conducted for the State of California, we implemented a decision analysis as a software tool (PLATFORM) to clarify an...

Structural System Reliability Framework For Fixed Offshore Platforms

The main objective of this project is to develop a generic framework which will set the basis for achieving more consistent system reliability assessments. The main steps involved in a system reliability assessment, together with the key technical and philosophical issues, will be identified and examined. Their interrelations and relative significance will be assessed in order to link them toge...

JIP: Structural System Reliability Framework For Fixed Offshore Platforms

Reliability Based Assessment of Existing Fixed Offshore Platforms Located in the Persian Gulf

This paper presents a detailed structural reliability procedure in order to achieve an acceptable safety margin for template type offshore platforms located in the Persian Gulf. Probability of failure in this study is calculated by considering the cumulative effects of all levels of wave loading during the lifetime of the structure and uncertainties associated with soil, material properties, co...
