120 SUPPORT VESSEL 



The water/air interface is troublesome at best, and particularly so in open-sea conditions. 

 The use of a crane to lift the PTC and mate it to the DDC leaves much to be desired. A capture 

 system with rigid constraints would seem a far better solution, although such a system would 

 be costly. 



One of the most useful movement indicators on the Berkone was the counterweight on the 

 dumb waiter leading to the shark cage. The overall range of movement provided an excellent 

 indication of sea conditions and synchronous pitching, which produced high loading on the moor- 

 ing legs and made handling of equipment with the Berkone crane hazardous.
