A method is described for the dampening of the roll movements of a ship at sea, said ship comprises one or more, in the main, transversely placed, partially filled with liquid, roll dampening tanks, where the liquid in the tank is set up to swing in antiphase with the roll movements of the ship to hinder that the ship rolls, where a measuring and a control system is used to register antiphase and possible deviations from said antiphase and the amount of liquid in the tank is regulated to achieve said antiphase. The method is characterised in that the height of the liquid up along the wall surfaces of the tank, in particular along the end wall surfaces, is measured and registered at any time with the help of one or more sensor elements, said height measurement data from the one or more sensor elements is registered in a monitoring system that determines said deviation from the ideal antiphase, and on the basis of said measurement data the system carries out a regulation of the amount of fluid in the tank to achieve said antiphase. Also described is a device for carrying out the method.

|7.||WO||WO/2013/066186 - A METHOD FOR QUICK STARTUP OF HOT GAS ENGINES/STIRLING ENGINES||10.05.2013||
|PCT/NO2012/000063||HEGGEN, Lars, Harald||HEGGEN, Lars, Harald|
The invention is a method for quick startup of Hot gas engines/Stirling engines. The problem with startup of Hot gas engines/Stirling engines is that they take a long time to reach normal operation. Long start up time becomes a problem for using such engines as emergency means either for powering of mechanical equipment or as an engine for a generator. The invention concerns using the heat required for evaporation of a liquid in order to quickly cool the cold side (3) of one or more Hot gas engines/Stirling engines. Cooling is performed by feeding a volatile liquid at startup from a pressure vessel (9) to a heat exchanger (11) mounted on the cold side (3) of a Hot gas engine/Stirling engine. Volatile liquids evaporate in the heat exchanger (11) at normal atmospheric pressure and thus low evaporation temperature. When used as emergency means, typically as an emergency cooling system for a nuclear reactor, Hot gas engines/Stirling engines are kept warm at its hot side (4) all the time before start up in order to quickly achieve normal operation. The engines are fully expanded before startup such that the working media is also heated. When using flammable volatile liquids (such as Propane) for cooling of the Hot gas engine/Stirling engine's cold side (3) it can be necessary to burn off the evaporated gas at the outlet (13). The flaring can also be used as a supplementary warning signal. The outlet (13) can be a catalytic flare. When using flammable volatile liquids for cooling of the cold side (3) of Hot gas engines/Stirling engines it is necessary to fill the heat exchanger (11) with an inert gas. If outlet (13) is mounted high over the heat exchanger (11), an inert gas that is heavier than air can be used. This gas is naturally stored in the heat exchanger (11). The heat exchanger's outlet (13) is equipped with a cap or other easily removable leak proofing means.
