The decompression barge received electrical power and a secondary low- 

 pressure air source from the surface support center. The barge was moored 

 to concrete clumps on the forward end and to steel cleats anchored in the 

 rock outcrop supporting the dive platform on the after end, A gangway 

 provided access between the barge and dive platform. 



DIVE PLATFORM 



The dive platform (Figure 8) was a roofed, wooden deck const:^ucted on 

 top of a large rock outcrop. It served as the duty station for the 

 support divers and housed the dive locker or equipment area and a scuba 

 charging compressor and air bank, A 60-foot steel girder bridge, over a 

 surge channel, connected the dive platform to the wooden steps leading 

 up to the surface support center, some 120 feet above the water line. 

 Power, air, and communication lines from the surface support center were 

 routed along the steps and bridge to the. dive platform and to the 

 decompression barge.
