METHOD AND APPARATUS FOR COMPENSATED WELL INTERVENTION OPERATIONS

摘要

A motion compensating support assembly provides a support framework, attachable to well platform, floating vessel or other underlying structure, for supporting well intervention operations. The motion compensation function can be manually controlled, or set to passive compensation mode. Hydraulic clamp assemblies can connect the compensating well intervention support assembly to structural member(s) of an underlying support surface or substructure.

主权项

1. A compensating support assembly for supporting a load over a well on a floating vessel comprising:
a) a lower frame member; b) an upper frame member movably disposed on said lower frame member, wherein said upper frame maintain said load in a substantially stationary position relative to said well; c) at least one hydraulic cylinder connecting said lower frame member to said upper frame member, wherein said at least hydraulic cylinder automatically extends or retracts to account for movement of said floating vessel.
