Thermal management systems and methods for thermally managing components for marine vessels

A thermal management system for a marine vessel, the thermal management system comprising:

• a first open loop circuit through which water from a body of water in which the marine vessel is operating is conveyed;
• a first closed loop circuit through which a first heat transfer fluid is conveyed;
• a first heat exchanger configured to exchange heat between the water and the first heat transfer fluid;
• a first plurality of components each cooled or heated by the first heat transfer fluid;
• a first valve having valve positions configured to vary a sequence that the first heat transfer fluid is conveyed to the first plurality of components so as to vary how the first plurality of components share the heating and cooling from the first heat transfer fluid and from the water from the body of water via the first heat transfer fluid, wherein in each of the valve positions of the first valve the first heat transfer fluid from the first heat exchanger enter the first valve via a same valve inlet and returns from the first valve to the first heat exchanger via a same valve outlet;
• a second closed loop circuit through which a second heat transfer fluid is conveyed;
• a second heat exchanger configured to exchange heat between the first heat transfer fluid and the second heat transfer fluid;
• a second plurality of components each cooled or heated by the second heat transfer fluid;
• a third closed loop circuit through which a third heat transfer fluid is conveyed;
• a third plurality of components each cooled by the third heat transfer fluid;
• and
• a second valve having a first valve position and a second valve position, wherein in the first position the second valve fluidly separates the second closed loop circuit and the third closed loops from each other, and wherein in the second position the second valve fluidly couples the second closed loop circuit and the third closed loop circuit in series such that the second heat transfer fluid and the third heat transfer fluid are each conveyed to both the second plurality of components and the third plurality of components.
