Abstract
A tear-away equipment removal system and method for use in controlling fires on offshore oil platforms. A preferred system includes a stab assembly connected to the end of the tension line and carried by a crane boom on a semi-submersible service vessel. A stab receptacle is provided in an outer wall of an offshore platform and is connected to large equipment units which block access to a fire site. The method includes maneuvering the service vessel and crane to allow connection of the stab assembly to the receptacle and the use of the tension line to physically tear open the outer wall of the structure and to remove the large equipment to provide clear access to the fire site.
