Product Sheet Top Mounted Compensator TMC-1000-25-2000
Used to compensate for the relative movement between the drilling vessel and seabed.
Cameron top-mounted compensator (TMC) systems are used to compensate for the relative movement between the drilling vessel and seabed. The large range of motion for our motion compensation equipment enables floaters to operate in some of the harshest environments. The compensator is highly accurate, with a 25-ft stroke and optional active cylinder and is supplied with an accumulator, valve block skids, air pressure vessels (APVs), control system, and optional air compressors.
The top mounting of the compensation system allows hook load variations to be addressed directly to the crown block, minimizing weight on bit (WOB) fluctuations. The careful placement of the compensation cylinders enables all standard top drives to be lifted between them, which means no reduction in the lifting height of the traveling assembly.
