gence problems and developments of the six- 

 ties. 



Another series of reports, also not readily 

 available, are the handbooks issued by the 

 U.S. Navy's Deep Ocean Technology (DOT) 

 Program. Recognizing the severe problems in 

 various electrical and mechanical components 

 in manned deep submersibles, the Navy began 

 this program in the late sixties, and the re- 

 sults are profitable reading for both present 

 and future submersible operators and design- 

 ers. The various components investigated can 

 be seen in the list below. Each handbook 

 summarizes the problems with available com- 

 ponents, solutions to some problems and rec- 

 ommendations for surmounting others. The 

 reports are limited in distribution to those 

 who have a legitimate need for such data, and 

 requests should be addressed to:

Submersible Work and Instruments 



Excluding the DOT handbooks, all of the 

 publications listed above contain accounts of 



various work performed by the particular 

 submersibles. Additionally, the references in 

 Chapter 11 relate specific work accomplish- 

 ments by a variety of submersibles. Notewor- 

 thy, is reference (1) of Chapter 11, which 

 summarized all of the published scientific 

 accounts of submersible work through 1970. 

 A popularized version of submersibles and 

 their accomplishments is contained in: 



Soule, G. 1968 Undersea Frontiers. 



Rand McNally & Company, New York 

 The references in Chapter 11 alsd describe, 

 to varying degrees, the instruments used to 

 perform certain tasks. The best single refer- 

 ence for work tools is Winget's report (ref. 6, 

 Chap. 11) which not only describes a wide 

 array of work tools, but also provides the 

 manufacturer's name and address for each 

 component used in each device described. 

 This report can only be described as a gold- 

 mine for the builder or designer of submers- 

 ible work equipment. 



Since the seventies most of the literature 

 describing submersible work is relatively 

 sparse. Perhaps because the work is no 

 longer mainly scientific and may be consid- 

 ered proprietary information by the user. 

 Virtually all recent accounts merely describe 

 the job as pipeline inspection, cable burial, or 

 the like, with details of the why, how and 

 performance of the vehicle and tools omitted. 

 Likewise, are accounts of submersible scien- 

 tific endeavors sparse regarding perfor- 

 mance of vehicles and instruments. Reports 

 of the National Oceanic and Atmospheric 

 Administration's Manned Undersea Science 

 and Technology Program relate what work 

 was done, why and, when possible, its scien- 

 tific implications, but nothing regarding the 

 performance, problems or solutions is in- 

 cluded. Such omissions, though clearly a pre- 

 rogative of the user, are unfortunate, be- 

 cause identifying and making known the 

 problem areas of submersibles is the only 

 means of providing direction or goals to the 

 designer of future vehicles. 



Soviet Bloc Submersibles 



Conspicuous by its absence is any discus- 

 sion of Soviet Bloc submersible design. The 

 reason is quite simple: There is no easy way
