Installation for harvesting energy of ocean currents (IHOC) in deepwaters is based on utilization of a semisubmersible platform and the multiple of vertically oriented Darrieus type hydraulic turbines. The turbines are located as close as possible to ocean surface, where speed of current is usually at its maximum. Since speed of current fluctuate during the seasons a system controlling buoyancy force of that keeps IHOC floating near surface is employed. The mooring system consists of three tethers, which prevent transferring of overturning moment applied to IHOC to anchoring base. The electric power generators are located in a machinery room on a structure well above sea level and would transmit electric power to the shore utilizing flexible cable. During hurricane it will be lowered to the depth preventing turbines from being affected by wave actions, at the same time it would keep machinery room above wave action. For the purpose of delivery assembled on shore Turbine Housing to destination site and installing it there a special convoy is formed consisting of Catamaran Delivery Barge and Stabilizing Platform.The second Embodiment of this invention is designed to harvest energy of tides in deepwaters.

A dual functionality temperature control measurement and low water cutoff measurement system is taught within a single tapping to a boiler.

A bow mounted vessel propulsion system is designed to exploit the characteristics of a self-producing vessel lubricating boundary layer of air or air bubbles formed during water surface interaction by the vessel's hull during vessel movement. This boundary layer of air / air bubbles will be produced at the bow of the vessel and, during forward motion, is superimposed upon the surface of the water as the vessel's hull passes over, reducing the frictional drag of the hull as it moves across and through the water. The system has a propulsion means such as a water surface-piercing propeller or water jet nozzles, which will propel the vessel forward and, at the same time, by action of propeller rotation (drawing air into and intermixing) in the water or water jet movement, will create the air bubbles which produce the hull-lubricating phenomenon. The hull is a substantially flat-bottomed planning hull with two linear rails on each lengthwise outer edge of the bottom surface of the hull. The rails extend downward into the water at a sufficient depth to be able to keep the boundary layer of air bubbles from escaping out from the sides of the hull bottom when the vessel is in forward motion.
