SUMMARY 



The Remotely Manned Undersea Work Systems developed at the Naval Ocean 

 Systems Center (NOSC) are herein described. This paper begins with a description and 

 analysis of typical underwater work tasks. Based on the function derived from the tasks 

 analysis, various underwater transporters (vehicles or divers systems) will be described; 

 the sensors required to locate and provide support at the work site will be discussed. Based 

 on the various components required to perform underwater tasks thus delineated, systems 

 synthesis is applied to provide the most efficient operations by best combining the comple- 

 mentary characteristics of each of the subsystems. 



The tasks denned and equipment described are applicable to most undersea oper- 

 ations such as survey, inspection, search, salvage, recovery of items from the seafloor, 

 emergency rescue of submersibles or habitats, as well as performance of dexterous tasks 

 on undersea installations.
