A thermal system for a marine vessel includes a thermal liquid circuit; a pump system for circulating a thermal liquid in the thermal liquid circuit; a number of thermal consumers; and a control device for controlling the pump system. The thermal consumers are arranged in parallel in the thermal liquid circuit, and the thermal consumers are arranged in series with respective Pressure Independent Control Valves (PICVs). A differential pressure sensor is adapted to sense a differential pressure indicative for the differential pressure over a critical one of the Pressure Independent Control Valves, and a signal from the differential pressure sensor is used by the control device as basis for controlling the pump system.

A method for removing internal moisture which tends to collect in the hulls, decks, stringers, transoms, bulkheads, spars, and other boat structures. Air injection bores are formed in the core or other boat structure in the vicinity of unwanted moisture. Pressurized injection air is injected into the bores through a plurality of air injection lines running from a source of pressurized injection air. The temperature of the air being injected into bores is varied as a function of the temperature and/or relative humidity of ambient air at or near the bores.

Disclosed is a composite thermal management system for an electric ship capable of maximizing the performance of a battery through efficient thermal management of a cabin, a battery, and a motor, and selectively switching between cooling and heating by a heat pump control method. The composite thermal management system for an electric ship selectively cools or heats a cabin, a battery, and a motor equipped in the electric ship, and includes a first heating and cooling unit that selectively switches a circulation cycle of a refrigerant according to a cooling or heating mode to cool or heat an inside of the cabin and a second heating and cooling unit that cools and heats the battery and the motor using coolant heat-exchanged with the refrigerant.

Proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. More particularly, proposed is a ship cogeneration system using waste heat of an LNG engine ship recovered through an economizer. The ship cogeneration system is configured to generate electric power by recovering waste heat generated from an LNG engine and providing high-temperature and high-pressure steam discharged from the economizer to an evaporator of an organic Rankine cycle. The ship cogeneration system is capable of removing soot generated on a contact surface between the exhaust gas of the LNG engine and the economizer by using some of the high-temperature and high-pressure steam.

A thermal management system for a marine vessel includes a closed loop circuit in which heat transfer fluid circulates, a first refrigeration component cooled or heated by the heat transfer fluid and configured to cool or heat air within a compartment on the marine vessel, and an open loop circuit.
