Abstract: Embodiments of the disclosure are directed to cellular sheet pile retaining wall systems with unconnected tail walls, and associated methods of use and manufacture. In one embodiment, a retaining system includes a face wall having a plurality of interconnected face wall sheet piles. The individual face wall sheet piles have a first length and extend a first depth into soil, and the face wall sheet piles form an exterior surface facing an exterior environment. The system also includes a tail wall including a plurality of interconnected tail wall sheet piles extending from the face wall away from the exterior environment. The individual tail wall sheet piles have a second length greater than the first length, and the individual tail sheet wall piles extend a second depth into the soil that is greater than the first depth.

Abstract: A soil retaining system combining flat sheet pile walls in an open cell configuration includes integral soil anchors providing an improved earth retaining system. Another aspect of the invention is a method of designing and installing a soil retaining system with an open sheet pile cell structure having integral soil anchors. The method includes, inter alia, calculating soil forces by taking into account material strength of sheet pile, soil friction against the sheet pile in combination with the strength of the integral soil anchor, selecting sheet pile size and length based on soil forces calculation; and installation of sheet pile to form a soil retaining system. The integral soil anchors serve to provide higher load resistance to the improved earth retaining system.

Abstract: Modular offshore platform systems and associated methods of transport and assembly are disclosed herein. A method of transporting a modular offshore platform to an offshore location in accordance with an embodiment of the disclosure includes transporting towing a first platform portion of the offshore platform to an offshore location and transporting a second platform portion of the offshore platform to the offshore location separately from the first platform portion. The method further includes attaching the second platform portion to the first platform portion at the offshore location, and anchoring at least one of the first and second platform portions to a sea floor at the offshore location.
