This paper will provide an overview of the decommissioning process and identify the resources required for project implementation. The results of the 1999 work season will be reviewed and analyzed to identify current trends and provide fact or fiction assessments of prevailing perceptions about decommissioning. The information utilized in preparing this paper was gathered from a variety of sources including owner, contractor, project manager and regulatory agencies. The decommissioning process includes tasks for engineering (planning, permitting, project management), preparation (well P&A, topsides preparation, pipeline decommissioning), removal (severing, platform) and disposal (reuse, reef or recycle). Removal technologies utilized included severing (explosives, abrasive water jet, mechanical cutter, diamond wire cutter and torch cutting), heavy lifting and handling. Disposal solutions implemented included reuse of the platform (equipment, deck and/or jacket), Rigs-to-Reefs and onshore scrapping/recycling. This paper will also outline the decommissioning challenges faced in the 1999 Gulf of Mexico work season and offer a list of future challenges facing our industry.
