ABSTRACT:
A system and method for evacuating endangered personnel from an offshore oil platform. The disclosed system includes; a self-propelled marine service vessel equipped with a large capacity revolving crane, a portable evacuation shelter located on the platform and including a single point connecting eye for attaching a recovery line thereto, and a support for the shelter attached to the platform and engaging the shelter from beneath so as to permit the shelter to be lifted vertically from the platform. A rapid evacuation of personnel from the platform can be accomplished even in heavy seas with the disclosed system by maneuvering a marine service vessel into a position near the platform, loading the personnel to be evacuated into the shelter, attaching tension cables from the boom of the crane to the single point connecting eye, while substantially maintaining the service vessel in the standoff position and lifting the shelter from the platform and transporting it to a position of safety on the deck of the service vessel.
