METHOD OF RAISING SUNKEN OBJECT AND COMPLEX FOR REALIZATION OF THIS METHOD Russian patent published in 2007 - IPC B63C7/08 B63C7/02 

FIELD: raising sunken objects.

SUBSTANCE: proposed method of raising sunken object includes lowering the sectionalized members with cargo-gripping unit from base ship positioned above sunken object, connection of it with sunken object, raising the sectionalized members and securing them on base ship followed by securing the raised object on base ship. Sectionalized members assembled preliminarily from lengths of wire ropes are secured on base ship and are lowered to entire depth of water basin. For raising the sectionalized members, use is made of pontoons lowered from base ship over guides of sectionalized members to limit depth corresponding to the pontoon envelope strength which are connected with transversal beams on sectionalized members. Simultaneously, after blowing the pontoons with compressed air, sectionalized members found on base ship are released and upon completion of pontoon raising procedure, they are again secured on base ship. Then, the cycle is repeated till completion of raising procedure.

EFFECT: possibility of raising sunken objects of considerable mass from deep depths at minimum input of labor; reduction of time required for erection work.
