A system for supplying fuel to an engine of a ship. The system includes a high pressure pump pressurizing a liquefied natural gas (LNG) and supplying the pressurized LNG to the engine, a hydraulic motor driving the high pressure pump and a chamber carrying the high pressure pump and the hydraulic motor. The chamber is substantially free of electric sparks.

The present invention relates to an arrangement for containment of liquid natural gas (LNG) in a hull compartment of a marine construction, comprising a self-supporting primary barrier, a second barrier surrounding the self-supporting primary barrier, and an access space between the self-supporting primary barrier and the secondary barrier. The self-supporting primary barrier is a liquid-tight self-supporting LNG tank and is connected with the hull compartment by support devices penetrating the secondary barrier. The secondary barrier is a liquid-tight thermal insulation connected with the interior surface of the hull and is sealed to the support devices by a flexible liquid tight seal, so that the self-supporting primary barrier and the secondary barrier are separately connected with the hull compartment to prevent transfer of forces between the primary barrier and the second barrier.

An in-water boat wash system includes pontoons constructed to float in a body of water in a spaced apart arrangement. A frame is attached to the pontoons such that the frame extends down and away from the pontoon into the body of water when in use. A tank is attached to or supported by the frame. A brush assembly is attached to the pontoon such that the brush assembly extends away from the pontoon into the body of water, the brush assembly shaped to clean the exterior of a boat. A nozzle assembly is attached to the pontoons such that the nozzle assembly extends away from the pontoon into the body of water, the nozzle assembly shaped to clean the exterior of the boat.

Disclosed are a device for reducing sloshing impact of a cargo hold for liquid cargo and a method for reducing the same. According to one embodiment of the present invention, the device for reducing the sloshing impact of the cargo hold for liquid cargo comprises: a rise guide unit which is installed at a proper place in a cargo hold, and includes a buoyant floating object that floats to the surface of the stored liquid; and a sloshing prevention member, which is restrained in the rise guide unit, floats the surface of the liquid by the floating object, and suppresses sloshing of liquid cargo.

A method for heating a cargo on a watergoing vessel using an energy source (such as a heat source) on another watergoing vessel. The vessels may be underway. The energy may be transferred to the cargo via energy umbilicals configured to carry energy in a transfer fluid. The transfer fluid may be circulated in a cargo heat exchanger configured to move energy into the hot cargo. The energy source on the another watergoing vessel may be a propulsion motor, exhaust heat, or non-propulsion heat source. The method may include heating the hot cargo. The method may also include switching between heat sources when both vessels are configured to heat the hot cargo.
