Abstract: A heat exchanger includes heat exchanger plates in a stacked arrangement such that each heat exchanger plate is spaced apart from the adjacent heat exchanger plate. The space between adjacent heat exchanger plates defines an external fluid passageway, and each external fluid passageway is configured to receive a first fluid. Each heat exchanger plate includes a peripheral edge, an internal fluid passageway configured to receive a second fluid. The internal fluid passageway includes an inlet and an outlet that open at the peripheral edge. The heat exchanger further includes a manifold having a supply chamber in fluid communication with the inlet of each heat exchanger plate and a discharge chamber in fluid communication with the outlet of each heat exchanger plate.

Abstract: An offshore structure for use with an OTEC system includes a submerged spar having a lower portion having a cold water intake. The cold water intake includes a domed terminus in fluid communication with a cold water pipe. A dry machinery space adjacent the cold water intake includes one or more cold water supply pumps and one or more cold water pipe lifting and retention winches having a lifting cable connected to the cold water pipe.
