摘要:
The invention is a watercraft to aircraft refueling system (“WARS”). A WARS is a refueling system based from a watercraft, such as a surface ship or submarine. A WARS would typically include an elevation apparatus to lift a refueling hose above the water. The elevation apparatus can compose a lifting or swiveling mechanism. In some embodiments both a lifting and swiveling mechanism is used. The WARS lifts the refueling hose above the water, allowing an aircraft to engage with the WARS. The refueling hose may also include a telescoping mechanism or a rotor apparatus or a pressurized water nozzle system to elevate the refueling hose and assist in engaging a WARS with an aircraft.

Provided is a liquefied gas treatment system for a vessel, which includes a cargo tank storing liquefied natural gas (LNG), and an engine using the LNG as fuel. The liquefied gas treatment system includes: a compressor line configured to compress boil-off gas (BOG) generated in the cargo tank by a compressor and supply the compressed BOG to the engine as fuel; a high pressure pump line configured to compress the LNG stored in the cargo tank by a pump and supply the compressed LNG to the engine as fuel; and a heat exchanger configured to liquefy a part of BOG, which is compressed by the compressor, by exchanging heat with BOG that is discharged from the cargo tank and transferred to the compressor.

The disclosure relates to an open-loop cooling system installed on a refrigerated barge for removing heat from an external heat exchanger in communication with a closed-loop internal cooling system. The system includes an open loop with a pump drawing water from the environment and forcing the water across the outer surface of the heat exchanger to augment existing heat removal due to contact with and flow of water across the heat exchanger due to the motion of the barge. Water is forced across the side faces and inner faces of the cooler to increase heat transfer from the barge closed-loop cooling system to the water environment.

A method for conversion of a Very Large Ore Carrier (VLOC) to an FLNG vessel for offshore stranded gas reservoirs and at-shore or near-shore Liquefied Natural Gas (LNG) export terminals.
摘要:
A floating LNG plant including a first and a second converted LNG carrier each provided with a hull and at least one LNG storage tank wherein the floating LNG plant further includes: a connection structure for connecting the hull of the first and the second converted LNG carrier in order to obtain a twin-hull vessel; process equipment for LNG processing on the floating LNG plant; and a mooring system for mooring the floating LNG plant to the seabed, wherein the at least first and second converted LNG carrier each include an LNG carrier, originally provided with a plurality of LNG tanks, wherein at least one LNG tank has been deactivated and/or removed from at least one LNG carrier to create space on the floating LNG plant for installing the process equipment for LNG processing.
摘要:
A towed vessel suitable for containing and transporting various liquids is disclosed. The vessel further comprises various features useful in the transportation, navigation, and storage of the towable vessel, both when in use for transporting fluids and when transported in an emptied state. Such features include navigational and positioning devices and methods, power supply devices and methods, and means for filling, inflating, emptying, and deflating a non-rigid, towed vessel. Aspects of embodiments of the present invention further include features useful for purifying or preserving the purity of the fluid to be transported.
摘要:
A support structure of a ship tank includes: a curved surface facing an outer peripheral surface of a horizontal type cylindrical tank; and a pair of support units supporting the tank on the curved surface. Each of the support units includes: a plurality of cylindrical elements arranged in a circumferential direction of the tank such that an axial direction of each of the cylindrical elements coincides with a radial direction of the tank; a plurality of inner members each holding an end portion of a corresponding one of the cylindrical elements at the tank side; and a plurality of outer members each holding an end portion of a corresponding one of the cylindrical elements at an opposite side to the tank. The inner members are fixed to the tank. The outer members of one of the support units are configured such that displacement of the outer members in an axial direction of the tank relative to the curved surface is restricted. The outer members of the other one of the support units are configured to be slidable on the curved surface in the axial direction of the tank.
摘要:
A rail system (40, 40′) of a ship (30) for positioning and arresting a hose (28) for supplying fluid material to an oil rig (10) from the ship (30) or supplying fluid material to the ship (30) from the oil rig (10). The rail system (40, 40′) comprises a rail (44, 44′, 46, 46′, 47) extending lengthwise at the upper edge of the bulwark of the ship (30). A vertical notch (48, 50) is provided in the rail having a bottom width corresponding to the diameter of the hose (28), and a locking element (52, 52′) of an elongated configuration being pivotally journaled adjacent to the vertical notch and being shiftable between a vertical position in which the hose (28) may be freely introduced into and positioned in the vertical notch (48, 50) and a horizontal position in which the locking element is blocking the entry into the notch and rests on the hose (28) for arresting the hose in the notch.
