FIELD: ship raising operations, raising sunken submarines for example.
SUBSTANCE: proposed method consists in securing the separable ship-raising pontoons in extremity where abscissa of point of application of raising weight of object determined by calculations is not located. Then, this extremity is raised due to replacing water in these ship-raising pontoons with gas, after which ship-raising pontoons are subjected to sidewise stropping and second extremity and submarine as a whole are raised keeping the change in trim within respective limits by proper positioning of pontoons.
EFFECT: reduction of labor input and time required for ship raising operations.
