摘要： A precast, modular marine structure and method of constructing the same for offshore use, including but not limited to drilling, oil and gas production, and oil storage in a variety of water depths. The marine structure includes an equalized pressure system and concrete modular components cast with at least one cell and a central longitudinal passageway. The equalized pressure system fluidly connects the cell(s) to the adjacent body of water by at least one substantially vertical segmented water column to equalize the hydrostatic pressure differential experienced at a wall of the marine structure. A truss section may be attached to the concrete portion of the marine structure to form a truss spar. A mooring and tether system may be included to maintain the marine structure's station and attitude. Construction of a marine structure includes assembly line techniques to form and cast individual modular components (such as a segment or module) in a position which encourages the pouring and curing of a concrete slurry; slipping the modular component from its form; translating the modular component into a position for mating with other modular components; and mating and connecting modular components with tendons to achieve a unitary marine structure.

摘要： The present invention is of a deepwater platform which incorporates a central two-piece tower extending from the ocean floor to at least a few feet above the ocean surface. The central tower is divided into an upper tower section and a lower tower section, with the lower tower section being substantially higher than the upper tower section. The tops of outwardly and downwardly positioned struts are connected to the tower at the dividing point between the upper and lower tower sections. Both the lower end of the central tower and the lower ends of the struts are anchored to the ocean floor by driving piles through pile sleeves secured thereto. The dividing line between the upper tower section and the lower tower section depends upon the angle at which the struts are positioned against the tower.

摘要： Method of erecting a minimal structure offshore platform around an existing caisson or drive pipe without any bolted, grouted, or underwater welded connections. This method involves the welding of a stop ring onto the caisson at a point just above the water line. A template having two sleeves for receiving piles and a sleeve for receiving a caisson is lowered over the caisson until the template rests on the stop ring. The template is concentrically aligned by a shim mounted to the top of the caisson sleeve. The caisson sleeve is centered around the caisson by inserting shims between the caisson and the caisson sleeve, and then the caisson sleeve is welded to the caisson and the stop ring. Piles are driven through the pile sleeves to grade using shims on the high point of the pile sleeve to align the pile with the axis of the sleeve as the pile sections are welded together. Once the piles are driven, the pile sleeves are centered around the piles by inserting shims between the piles and the piles sleeves. The pile sleeves are then welded to the piles. The deck of the structure is then installed using the template as the support.

摘要： A corrosion protection system for protecting critical parts of an offshore structure. The structure is composed of an assembly of critical parts representing a small portion of the structure and noncritical parts representing a large portion of the structure. The critical parts are coated with a layer of material to form a protective treatment so that the critical parts are made electrochemically noble or passive relative to the uncoated noncritical parts when the offshore structure is submerged. The noncritical parts are electrochemically active relative to the coated critical parts to provide for cathodic protection current supplied to the coated critical parts by the uncoated active parts to produce corrosion protection to the coated critical parts. An accelerated corrosion system for destroying the critical parts uses a conductive layer including a slit and with the slit initially protected and then removed to accelerate corrosion to destroy the offshore structure.

摘要： For rapid assembly of the deck of a drilling platform on a pipe scaffold, a connecting element made of two interlocking parts is described. The first part is in the form of a closing head integrated by casting into the end of a vertically standing pipe of the pipe scaffold, a ring-shaped horizontal support surface and a lifting bitt extending upward. The second part is in the form of a bell-shaped cover which envelops the lifting bitt. The cover on its upper surface is welded to the drilling platform, and at its underside includes a supporting surface which bears upon the supporting surface of the first part.
