ABSTRACT:
A subsea abandoned wellhead protection system which may be installed underwater without the need for underwater assistance from divers or the like, the system allowing full site preparation and installation from the surface. The present invention teaches a new and unique system for the lowering and centering of the shelter over the wellhead, as well as a new system for the preparation of the installation site, including the removal of debris from the site and excavation of the ground surface area about the abandoned wellhead via a remote, fluid actuated, integrated excavation system. The present invention, with the utilization of a somewhat frustoconically or pyramidally configured shelter structure, uses a conduit system from the top of the structure to the base, terminating in a plurality of excavation jets about the periphery of the base area, providing a fluid stream of adjustable intensity (depending upon the excavation surface) for "trenching" the installation area, thereby allowing the base of the structure to sit below the ground surface. The present invention provides a new, innovative, and less expensive system for the installation of abandoned wellhead shelters and the like in an underwater environment.
