Installation of superstructure 



above the top- center of the float. The gratings are in small 

 removable sections for ease of access. 



The superstructure also prevents direct wave impinge- 

 ment on the delicate equipments located on top of the float. 

 Several times off Guam, equipment was either damaged by 

 wave action or carried over the side, and it was merely- 

 good fortune that no dives had to be aborted through loss of 

 vital equipments. 



Recent sea tests with the new superstructure have 

 proved it to be entirely satisfactory. An additional advan- 

 tage is that it provides an ideal surface for the small boat 

 to come alongside for transfer of personnel and equipment. 

 In the past, the round hull configuration of the float, which 

 tends to lie broadside to the prevailing seas, made this 

 extremely difficult. With the new superstructure and with 

 life lines rigged to prevent personnel from being carried 

 over the side, the sea operations are considerably safer.
