ADMINISTRATIVE INFORMATION 



This effort has been completed by the Ocean Technology Department of the Naval 

 Ocean Systems Center in cooperation with the U.S. Department of the interior, Geological 

 Survey, Reston, Virginia. This work was funded by Mr. John Gregory of the U.S. 

 Geological Survey under program element FGOV, work unit number 52 1-MS3 1 . It is part 

 of a total research-and-development program designed to supply the technology required 

 for pollution prevention and safety in outer continental shelf oil and gas operations. Un- 

 manned, untethered submersible systems have a significant potential for upgrading the 

 scope and complexity of these inspection missions in a cost-effective manner. The investi- 

 gation of unmanned submersibles for pipeline and structure inspection represents an 

 attempt to transfer technology from the Navy's Ocean Technology Program for use in these 

 inspection missions. The Navy, in turn, will be able to adapt the untethered vehicle techni- 

 ques to search and recovery operations at sea.
