摘要

A fatal accident occurred on 18 April 2011 at approximately 0330 hours on WC 643 A Platform, located in West Cameron Block 643, OCS-G 02241, operated by Hilcorp Energy Corporation GOM, LLC. The accident occurred during work to plug and abandon (P&A) the wells and decommission the platform, primarily conducted by Alliance Oilfield Services, Inc., contracted by the operator. Plug and abandonment of Well A-2 was underway on the main deck of the platform using a power swivel skid, casing jack, and crane. At 0330 hours, the power swivel was being moved by the crane from atop the well. A roustabout who was acting as a rigger to help control the load, stepped or was dragged by the moving load, into the opening in the deck exposed by the lift of the power swivel. The subsequent 30-ft fall resulted in the fatality. Night medevac callout was delayed due to confusion in emergency planning.
