Multi-lobe tank for containing pressurized liquids, such as liquefied gas, for mounting into a ships hull, wherein the tank comprises at least a first longitudinally extending multi-lobe tank part having a center line and a second longitudinally extending multi-lobe tank part having a center line that are positioned behind each other resulting in a forward multi-lobe tank part and a rear multi-lobe tank part with aligned center lines, wherein the first part can tapered towards an end of the first part.

A method of transporting natural gas by liquefaction of natural gas at ambient temperature, achieved by mixing the natural gas at high pressure with a hydrocarbon that is a stable liquid at ambient temperature and ambient pressure. The hydrocarbon liquid may be crude oil or a distillate of crude oil. The method includes: liquefaction: mixing the natural gas with the hydrocarbon liquid at an ambient temperature and a high pressure to generate a liquid mixture, which contains the natural gas dissolved in the hydrocarbon liquid; shipping: transporting the liquid mixture using a marine tanker, during which the liquid mixture is maintained at ambient temperature and the high pressure; and regasification: at the destination, releasing a gas from the liquid mixture by lowering the pressure of the liquid mixture. The hydrocarbon liquid may be used multiple times.

An installation and method for storing liquefied gas, comprising a plurality of separate storage tanks each configured to contain liquefied gas, comprising a cooling circuit provided with a refrigeration device, a withdrawal pipe and a plurality of first injection pipes towards each of the tanks in order to cool the withdrawn fluid flow, the tanks comprising a degassing line, the installation comprising a set of controlled valves situated at least in the cooling circuit, wherein the first tank contains liquid and at least one other tank is empty, containing essentially boil-off gas, that is to say containing little or no liquid, wherein there is cooling of the fluid contained in the first tank, re-injection into the first tank, injection of liquid cooled by the refrigeration device into at least one other empty tank and transfer of boil-off gas generated in the or the other tanks to the first tank

A bunkering vessel according to the present invention is for loading a liquefied gas to and unloading a liquefied gas from a liquefied gas storage tank of a target, and it includes a bunkering tank storing a liquefied gas; a manifold provided at a bunkering station of the bunkering vessel to flow in a liquefied gas to and flow out a liquefied gas from the bunkering vessel; a liquefied gas transfer line connecting the bunkering tank and the manifold to flow a liquefied gas; and a dry gas supply portion producing a dry gas, and the dry gas supply portion supplies a dry gas to the liquefied gas storage tank through the manifold before loading a liquefied gas to the liquefied gas storage tank to remove moisture inside the liquefied gas storage tank.
