A ship comprising an engine is disclosed. The ship comprising an engine comprises: a self-heat exchanger which heat-exchanges boil-off gas discharged from a storage tank; a multi-stage compressor which compresses, in multi-stages, boil-off gas that passed through the self-heat exchanger after being discharged from the storage tank; a first decompressing device which expands one portion of boil-off gas that passed through the self-heat exchanger after being compressed by the multi-stage compressor; and a second decompressing device which expands the other portion of the boil-off gas that passed through the self-heat exchanger after being compressed by the multi-stage compressor, wherein the self-heat exchanger uses boil-off gas discharged from the storage tank and boil-off gas expanded by the first decompressing device as refrigerants for cooling boil-off gas compressed by the multi-stage compressor.

A mobile CO2 filling system selectively fills onsite CO2 storage and dispensing systems with CO2. The system includes a mobile platform; a tank holding liquid CO2 mounted on the mobile platform; a flexible dispensing hose couple to the tank and configured to be selectively coupled to the filling inlet of an onsite CO2 storage and dispensing system; a pump selectively coupled to the tank; and a controller for controlling the filling of an onsite CO2 storage and dispensing systems with CO2 from the tank, wherein the controller is selectively designated by the user to operate in at least one pump assisted filling state and at least one gravity feed filling state.

An offshore LNG processing plant includes a first module including a personnel accommodation facility on a first vessel, a second module including a gas treatment facility on a second vessel, and a third module including a gas liquefaction facility on a third vessel. Each of the first, second, and third modules are assembled on the corresponding vessels, and then transported to an offshore location in a body of water, such as a river, a lake, or a sea. At the offshore location, each vessel deploys legs to the bed of the body of water to raise a hull of each vessel out of the water. The first module is then coupled to the second module, and the second module is coupled to the third module. A fourth module on a fourth vessel is coupled to the third module to provide LNG storage.

Methods and apparatus for cryogenic fuel bayonet transfers are disclosed. A disclosed example fuel transfer system includes a fuel tank. The example fuel transfer system also includes a bayonet receptacle extending into an internal volume of the fuel tank, where the bayonet receptacle is to receive a fuel transfer bayonet to fill the fuel tank with fuel and a fuel discharge bayonet to discharge the fuel.
