Raized vessel utilization
Depending on the goals set, working conditions and the state of the sunken object, in practice, several lifting methods are used:
- sealing and pumping out water from the compartments by pumps;
- displacement of water from the compartments by compressed air;
- lifting with the help of inflatable soft pontoons or blown pontoons fixed to the hull;
- lifting with floating cranes.
The specific method in each case is determined individually, depending on the depth of the object, its condition, size, degree of siltation, bottom characteristics and other parameters.
