Further, the first temperature sensor (240) is configured to measure a first temperature value and transmit the first temperature value to the control module (140). Also, the control module (140) is configured to open the primary first three-way valve outlet (2302) and discharge the effluent sea water overboard through an overboard line, if the first temperature value is higher than a reference temperature value.

A LG module for a marine vessel (1), said LG module (10) comprising a support structure for loading and unloading said LG module (10) onto said marine vessel (1), at least one LG tank (12) and a LG gas processing unit (13) for processing LG to fuel, said fuel fulfilling the requirements of an engine of said marine vessel (1).

Disclosed are gas cylinder assemblies for containing pressurized gas. The gas cylinder assembly has a polymeric liner and a low-permeability barrier layer. The polymeric liner a first end portion, a second end portion and a central body. The central body comprises an outer surface and an inner surface disposed between the first end and the second end. The gas cylinder assembly comprises a reinforcement structure wound over the central body. The gas cylinder assembly further comprises a metal foil interposed between the reinforcement structure and central body. The metal foil is configured to reduce permeation of contents of the polymeric liner.

The method of transferring compressed gas at from a first tank to a second tank without decompressing the compressed gas and then re-pressuring the compressed gas comprising filling the second tank with a fluid, connecting a first fluid connection on the first tank to a second fluid connection on the second tank with a first line with one or more first valves, connecting a first gas connection on the first tank to a second gas connection on the second tank with a second line with one or more second valves, opening the first valves and the second valves to allow the compressed gas to pressurize the fluid, and pumping the fluid in the second tank into the first tank, thereby causing the compressed gas in the first tank to be displaced into the second tank.

A sensor mounting assembly is configured for use with a vessel arrangement including at least four vessels. The assembly includes first and second elongated frame members, first and second rollers, and first and second sensors. The first sensor is attached to the first elongated frame member and is configured to contact the surface of the first vessel upon actuation in a first direction. The second sensor is attached to the second elongated frame member and is configured to contact the surface of the second vessel upon actuation in a second direction that is substantially orthogonal to the first direction. This disclosure also describes a method of mounting at least six sensors for use with a vessel arrangement including at least four vessels, the vessel arrangement disposed in a container in a two-by-two stacked configuration having a central space.

A regasification facility, regasification systems and methods for import, offloading and regasification of liquid natural gas from liquid natural gas carriers is provided. The regasification facility is configured to provide increased flexibility in the construction so as to enable substantial reductions in construction times and costs of the construction of the regasification facility to be constructed and brought into operation, and to be further scaled up quickly and efficiently versus traditionally constructed and operated land based regasification plants and/or floating storage and regasification units.
