Bottom-supported vessel for performing subaqueous operations and method of placing a bottom-supported vessel in position for performing subaqueous operations

摘要

A bottom-supported vessel from which subaqueous operations may be performed. The vessel includes a platform and a mat, both of which are configured to permit the platform to nest within the mat while the vessel is floating. The mat is submersible and is adapted to be buried into the soil beneath the ocean floor to provide support for the platform. Legs extend from the mat to the platform and support the platform when the mat is buried. A method of placing a bottom-supported vessel in position for performing subaqueous operations.
