A wind turbine foundation comprising a concrete support slab having a horizontal rebar grid therein, a concrete pedestal integral with the support slab and having vertical post tensioning elements therein and a plurality of concrete ribs on top of and integral with the support slab and integral with the pedestal, the ribs having rebar therein and extend outwardly from the pedestal, the pedestal, slab and ribs are connected to each other to form a monolithic foundation. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.

An offshore ocean floating platform equipped with a docking bay with a hull made with multiple steel barrels welded to each other arranged in multiple layers, an upper deck with living premises, laboratory and control tower, having three submersible plankton pumping towers extending from above water level up to 120′ depth, a manned and aerated research submersible vehicle with vertical travel controlled by a telescopic double acting actuator, including two telescopic aeration tubes providing atmospheric pressure air from above sea level, and safety return springs, sealed glass windows, water depth gage and video cameras. The upper deck having plankton pools plankton pumped from ocean floor by a piston traveling within a cylinder by double acting telescopic actuator for fishery feedings. All towers bottom-end secured to seabed dirt with multiple heavy cement poles with embedded cylinder and piston moving under ocean water high pressure into seabed dirt with self-drilling plungers.

A fatigue resistant gravity based spread footing under heavy multi-axial cyclical loading of a wind tower. The foundation having a central vertical pedestal, a substantially horizontal continuous bottom support slab, a plurality of radial reinforcing ribs extending radially outward from the pedestal. The pedestal, ribs and slab forming a continuous monolithic structure. The foundation may have a three-dimensional network of post-tensioning elements that keep the structural elements under heavy multi-axial post compression with a specific eccentricity intended to reduce stress amplitudes and deflections and allows the foundation to have a desirable combination of high stiffness and superior fatigue resistance. The foundation design reduces the weight and volume of materials used, reduces cost, and improves heat dissipation conditions during construction by having a small ratio of concrete mass to surface area thus eliminating the risk of thermal cracking due to heat of hydration.
