An assembly for storing and transporting compressed fluid, such as compressed natural gas (CNG) that includes; a plurality of hexagonally stacked pipe stored in a cargo hold in or on a vessel, such as a ship or barge, that includes a lower support, side supports and a forcing mechanism that presses so strongly down on the pipes that they cannot move relative to themselves or relative to the vessel on which they are placed in any service situation. The friction between each of the pipes causes the plurality of pipes to act as part of the vessel in terms of its structure. Each of the pipes in the plurality of pipes is connected to a manifold system to allow or the loading and unloading of the compressed fluid.

The invention discloses a bimetallic cryogenic membrane storage compartment for liquefied natural gas (LNG) storage. The invention is based on the design of bimetallic membrane panels and two insulating panels to achieve two completely independent insulation spaces, fully meeting the relevant requirements of the amendments to the International Code for the Construction and Equipment of Ships Carrying Liquefied Natural Gas in Bulk (“IGC CODE”) adopted on May 22, 2014. The invention improves the safety of the cryogenic membrane storage compartment, reduces the limitation of free liquid level loading of liquid cargo in the cargo compartment, reduces the application and time consuming of low-temperature resistant glue in the construction process, and adopts the more mature and safe design method of welding bimetallic membrane panels and the environmental protection method of prefabricated foam insulation panels, thus reducing the construction workload, shortening the construction cycle and improving the safety of the equipment.

A raw water isolator for watercraft for providing treated fluid to loop of air conditioning units, freezers, ice makers, gyro stabilizers and the like systems. The raw water isolator provides a closed loop of treated fluid to prevent such systems from exposure to raw water known to contain biological material capable of fouling the units, and associated corrosion when salt water is used for the cooling mechanism. The apparatus employs a storage and expansion tank for holding a volume of fluid that is circulated through the marine units. A heat exchanger selected for ease of cleaning provides heat transfer between the cooling fluid and raw water.

Disclosed herein are a fuel supply system for ships and a fuel supply method using the same. The fuel supply method includes: 1) supplying an excess amount of liquefied gas as fuel to an incompressible fluid-fueled engine (E); 2) cooling unconsumed fuel discharged from the engine (E) through heat exchange with liquefied gas discharged from a storage tank (T); 3) returning the unconsumed fuel discharged from the engine (E) and having been cooled through heat exchange in step 2) to the storage tank (T); and 4) supplying the liquefied gas discharged from the storage tank (T) and having been used as refrigerant for heat exchange in step 2) to the engine (E). The fuel supply method can prevent cavitation in the engine (E) by supplying the excess amount of liquefied gas sufficient to accommodate variation in load of the engine (E) as fuel to the engine (E).
