FIELD: transport.
SUBSTANCE: invention relates to underwater operations, particularly, to boarding of sunken large weight bulky objects in rough sea with strong current. Claimed WRLP is provided with pontoons of oval and oblong shape and features wave resistance in surface position against limited-intensity waves at partial filling of ballast tanks and higher wave resistance at complete flooding of said ballast tanks and submergence of columns by about 1.2 of the wave design amplitude. WRLP increased wave resistance results from perfected shape of columns. For handling jobs, said WRLP is provided with handling device incorporating two-link load lowering and lifting hardware and the adequate procedure for its control which allows a required margin of buoyancy and stability at lifting and transportation of cargoes.
EFFECT: enhanced performances of claimed WRLP.
