According to some embodiments, a flexible regasification system comprises a floating liquefied natural gas (LNG) storage vessel; a LNG vaporizer disposed on a jetty proximate the LNG storage vessel to vaporize the LNG into natural gas; and a thermal fluid source. The LNG storage vessel is coupled to the LNG vaporizer and supplies LNG to the LNG vaporizer. The thermal fluid source is coupled to the LNG vaporizer and sends heated thermal fluid to the LNG vaporizer for converting the LNG to natural gas, which converts the heated thermal fluid to a cooled thermal fluid. The cooled thermal fluid is discharged back to the thermal fluid source, comprising a closed loop. In particular embodiments, the thermal fluid storage comprises a floating vessel disposed near the jetty. In some embodiments, the cooled thermal fluid from the LNG vaporizer is first sent to a power plant or refrigeration plant.

A heat exchange system for use on an engine-powered watercraft includes a liquid cooling system for cooling the engine using a first heat exchanger and a water heating system using a second heat exchanger for heating water. Raw water from an external water source is passed through each heat exchanger. Water used to cool the engine coolant inside the first heat exchanger exits the watercraft. Water heated by the second heat exchanger is passed to either an intake conduit or at least one onboard accessory system for flushing thereof to kill aquatic invasive species. A valve inside the second heat exchanger opens to release heated water when the heated water reaches a temperature of at least 140 F. Heated coolant from the first heat exchanger passes through the second heat exchanger to transfer heat to the water inside the second heat exchanger.

An assembly comprises a wet compartment (100) having at least one inlet opening for allowing water to enter the wet compartment (100), a functional unit (2) located in the wet compartment (100), a dry area (200) which cannot be reached by water and which is outside of the wet compartment (100), a barrier (110) situated between the dry area (200) and the wet compartment (100), and at least one energy source (20) which is arranged and configured to emit energy for preventing biofouling of at least an exterior surface (17) of the functional unit (2), wherein the energy source (20) is arranged in the dry area (200), a path (112) being present between the dry area (200) and the wet compartment (100) for allowing energy emitted by the energy source (20) during operation thereof to reach the wet compartment (100), through the barrier (110).
