A MOTION-COMPENSATED LAUNCH/RECOVERY CRANE

Oceanographic instrumentation towed from a surface platform is normally subjected to unwanted vertical motion by the rolling, heaving and pitching of the platform. This motion can cause severe shock-loading conditions in the tow cable and induces unplanned depth variations that reduce the instruments' resolution. This article discusses a unique motion-compensation system for use with towed instrumentation that eliminates shock loading and minimises depth variation. The system is operational in sea states as high as 5 and effectively decouples 96% of the vessel's motion.
