摘要:
The present invention relates to a method and a system for circulating ballast water on board a vessel where the ballast water to be circulated passes into a tank (10) as filling water through a filling unit (21), and discharged as discharging water from a discharging unit (22), the system comprising a ballast water tank (10), an inlet pipe system (11) for filling water and an outlet pipe system (12) for discharging water. A floating unit is arranged inside the inlet pipe (11) for distributing the filling water at the water surface (14).

This publication relates to a method and a system for providing a more or less even or uniform temperature on a surface of an object to be heated, such as for example stairways (14), handrails (15) or the like on board a vessel. The method and the system comprises circulation of a heated thermal fluid from a heat source (21) through a piping system to a heating means arranged in association with the object to be heated and back to the heat source for re-heating, the piping system incorporating one or more pumps (22); one or more manifolds (23,23'25,25'), one or more valves, one or more means for measuring and/or controlling pressure, temperature and/or flow rate(s). The heating means is in a form of at least one heating element (24), configured to provide a more or less even or uniform surface temperature on the entire surface of the object to be heated,in order to keep the energy consumption and the thermal fluid flow as low as possible.

摘要:
This publication discloses a method and a system for treating water on board a vessel before discharging such water to the sea. The water to be treated is pumped through a primary heat exchanger (12) where the water is pre-heated and then through a secondary heat exchanger (13) where the water is further heated, the secondary heat exchanger (13) being heated by thermal fluid from a central heating system primarily heated by heat recovered from different type of heat generating equipment and also possibly by fuel and/or electricity in cases where the heat recovered from the heat generating systems is not sufficient to treat the water in a sufficient manner.
摘要:
A heating system and a method for heating a plurality of tanks (11) intended to contain a liquid onboard marine installations or vessels, based on circulation of a thermal liquid, such as water and/or glycol. Each tanks (11) is provided with at least one heating element (17) and associated piping system (20,21 ) for supply and discharge of the thermal fluid, and an inlet (12) for loading the fluid to be stores and an outlet (13) for discharging the stored fluid. Further, each tank is preferably also being provided with a primary circulation system including a pipe system with at least a valve and pumping unit (14,16) associated with said inlet (12) and outlet (13) for circulation of the liquid in the tank (11). The at least one heating element (17) and associated piping circulation system (20,21 ) is a closed circulation system, comprising a heat delivering heat exchange (23), a circulation pipeline system (20) delivering heat to at least one heating element (17) in the tank (11) and an actuated valve (22) arranged in the supply line (20) for each tank (11) for separately controlling the rate of circulation of heated liquid through the heating element (17), the heating element (17) comprising at least one small sized, high performance removable heating coil, and that the system includes a system for controlling the volume of heat delivered separately to each tank (11).
