Abstract : Two models of Manned Underwater Stations were towed in still water as well as in waves. The resistances were measured and the optimum towing configurations recommended. The response curves for added resistance were derived from uniform wave tests. Then the added resistances were calculated for sea states 3 and 5 and compared with model tests. Dynamic forces in towing cable (caused by wave action) were measured. Some measurements were made to estimate overturning as well as oscillatory moments produced by bottom currents while the station is sitting on the bottom. (Author)
