A system for offloading LCO 2 cargo from an LCO 2 carrier ship to an intermediate LCO 2 storage tank at an LCO 2 receiving terminal, which system avoids cross-contamination of cargo from one LCO 2 carrier ship to another, said system comprising: - an intermediate LCO 2 storage tank; - a boil-off gas outlet from the intermediate LCO 2 storage tank configured to withdrawing boil-off gas from the intermediate LCO 2 storage tank; - an LCO 2 cargo import conduit (1, 10) connected to the intermediate LCO 2 storage tank configured to receive an LCO 2 cargo import stream from the LCO 2 carrier ship; - a CO 2 vapour return conduit (4, 5, 6, 7, 8, 9) configured to be connected to the LCO 2 carrier ship and to return from the system CO 2 vapour to the LCO 2 carrier ship; - an LCO 2 outlet from the intermediate LCO 2 storage tank configured to discharging LCO 2 from the intermediate LCO 2 storage tank; characterized in additionally comprising, - an LCO 2 slip stream conduit connected to the LCO 2 cargo import conduit configured to withdrawing a slip stream of LCO 2 from the LCO 2 cargo import conduit; - a pressure let-down valve connected to the LCO 2 slip stream conduit configured to receiving the slip stream of LCO 2 having a first temperature, and to exiting an at least partly vaporised stream of LCO 2 having a second lower temperature; - a partly vaporised stream conduit connected to the pressure let-down valve configured to receiving the at least partly vaporised stream of LCO 2 having a second lower temperature; - a boil-off gas conduit connected to the boil off gas outlet; - a first heat exchanger connected to the partly vaporised stream conduit and to the boil-off gas conduit, respectively, said heat exchanger being configured to receiving the at least partly vaporised stream of LCO 2 having the second lower temperature, to receiving the boil-off gas withdrawn from the boil-off gas outlet, to transferring heat from the boil-off gas to the at least partly vaporised stream of LCO 2 having the second lower temperature, to exiting a reliquefied fraction from boil-off gas and to exiting an at least partly vaporised stream of LCO 2, respectively; - a reliquefied fraction conduit (12, 15) connected to the intermediate LCO 2 storage tank configured to receiving the exiting reliquefied fraction from the first heat exchanger; - wherein the CO 2 vapour return conduit (4, 5, 6, 7, 8, 9) is further configured to receiving CO 2 vapour resulting from the at least partly vaporised stream of LCO 2 having the second lower temperature; and - a vapour return compressor arranged along the vapour return conduit (4, 5, 6, 7, 8, 9) configured to compressing the CO 2 vapour to be returned to the LCO 2 carrier ship. - an intermediate LCO 2 storage tank;
