Crown Mounted Compensator

Drill String Compensator

Effectively separate heave motion from the drill bit

Drill String Compensators are designed to isolate, as much as possible, the heaving motion a the vessel from the drill string, providing a constant load on the bit while drilling. They minimize wear between the drill string and the blowout preventer, marine riser and casing strings.

Maritime Hydraulic and MHD Offshore Group manufacture both CMC and In-Line Drill String Compensators to meet ASME, ABS, USCG, DNV, and other applicable codes.
