In order to extend the weather operations window of tethered Remotely Operated Vehicles (ROVs), it is not only desirable, but necessary to include a motion compensation system in the basic system hardware. The need becomes more critical as the size, weight, depth of operation, and cost of the vehicle increases. This paper looks at the background of motion compensated cranes and discusses field experience with a motion compensated boom. The Launch/Recovery Motion Compensator (LRMC) has proven itself to be very effective, reliable, easy to use, and safe. The LRMC is consistently capable of reducing the total vertical acceleration of the tow point by 85 %, with in-band motion reductions as high as 96 %. The boom type motion compensator is regarded as the 'best' method of protecting the tether cable from wear and fatigue. The LRMC is an important component of the tethered Remotely Operated Vehicle System, increasing productivity and safety while decreasing cost.
