An advanced submersible handling system

An overview of shipboard submersible handling systems, representing current practice is presented. The simple A-Frame, articulated and pedestal-type cranes, and moon pool systems are evaluated, with attention given to the weather/operations corridor provided by each system. Described is a system particularly suited to research vessels. The system, a hybridized A-Frame, incorporates technology which has proven highly successful in hostile North Sea operations. It comprises a motion compensating lift winch, hydraulically controlled pendulation, and is of light weight, aluminum construction. Further discussion is devoted to emerging technology, and a forecase of future systems.
