Figures. DIVERCON I. 



The DIVERCON I project, a concept already tested and proven during 

 shallow water tests in 50 feet of water, will be attempted again during 

 Sealab III at a depth of 600 feet. 



In future construction projects, whether diver assisted or at depths 

 beyond present diving limits, some of the problems and solutions encountered 

 in DIVERCON I will develop. Construction modules may be lowered to the 

 approximate bottom site and coarse alignment will be provided by the surface 

 vessel, underwater winches, guidelines, or by manned or unmanned submersi- 

 bies. Guide rods, keyways, or electronic devices will then provide the fine 

 alignment necessary to construct large, integrated sea floor installations.
