Compensating Sheave
The BenchMark Wireline compensating sheave is a heavy-duty wireline cable-handling device that is part of the wave motion compensating system used on offshore rigs and platforms.
Wave motion experienced on offshore platforms requires specialized systems designed to compensate for the movement. The compensating sheave handles the connection
between the deck and the marine riser. The wire/cable to which the logging tools are attached are also connected to the compensating sheave.
BenchMark Wireline compensating sheaves are purpose-built to match a platform’s wave motion compensator. The large cross tee is designed to fit inside a platform’s compensator block.
The swivel block rotates a full 360°. A locking pin safely holds the block in a stationary position to allow entry of 25mm wire rope.
During design every aspect is carefully considered to reduce weight and maximize the ease of handling the unit.
The compensating sheave is manufactured to comply with all pertinent regulations.
All compensating sheaves are fully tested before shipping.
