TRANSSHIPMENT METHOD FOR BULK CARGO ON UNIVERSAL TANKERS AND FLEXIBLE LINER «TANKERPACK REMOVABLE COATING» Russian patent published in 2021 - IPC B63B25/12 B63B27/24 B67D9/00 

FIELD: ship cargo handling.

SUBSTANCE: invention relates to the field of ships cargo handling, in particular tankers. Transshipment method for bulk cargo on universal tankers, including stages of loading and unloading of cargo, is proposed. Before loading, flexible liners are placed in cargo tanks, the inlet and outlet openings of which are located in its upper part, and which are fixed in corresponding openings of the upper cargo hatches of tanks, after which the flexible liners are straightened in cargo tanks. A temporary cargo system is assembled, including a deck trunk pipeline with adapters and portable hoses, which are lowered into the holes of flexible liners placed inside cargo tanks. Then, with the help of equipment located in port, cargo is loaded into tanks by pouring it through the upper cargo hatches of tanks inside flexible liners. When loading is completed, the temporary cargo system is dismantled, its components are purged and stored in designated storage areas on the tanker. For unloading a temporary cargo system with submersible pumps is assembled, which are fixed at the ends of portable hoses, portable hoses with submersible pumps are lowered into flexible liners, with the help of submersible pumps, bulk cargo is unloaded from tanks into containers intended for this purpose located in port. Then the temporary cargo system is dismantled, its components are purged and folded in designated storage areas on the tanker, and flexible liners are removed from cargo tanks and sent for disposal. A flexible liner is also proposed for use in transshipment method for bulk cargoes.

EFFECT: invention reduces time of tankers cargo turnover, reduces polluting impact on environment.
