METHOD OF MOUNTING UNDERWATER OPERATIONS COMPLEX ON WATER AREA BED AND UNDERWATER OPERATIONS COMPLEX Russian patent published in 2009 - IPC B63B35/44 

FIELD: ship building.

SUBSTANCE: invention relates to deep-water equipment, in particularly, to the method of organising manned underwater labs and stations, both self-contained and towed, and to the device to this end. The proposed method of mounting underwater operations complex on water area bed and removing it therefrom consists in imparting negative buoyancy to the complex for it to be set on the bed. An air bell is created inside the complex top for gas medium pressure to be kept up therein and, at a time, water is pumped out from the complex housing inside to ensure forces pressing the housing to the bed. To remove the complex from the bed, it is gradually deluged along with bypassing air (gas medium) from the complex housing into ballast tanks to impart buoyancy to it and to lift it off the bed. Note here that complex has the housing furnished with a skirt. The complex housing top edge is located in air (gas) medium of the said bell, while the bell top accommodates ballast tanks.

EFFECT: increased depth of complex mounting, longer operation on bed soil in gas medium.
