Abstract: Systems and methods for fabricating a retaining wall include an operation for making an untreated wall in the ground. This may be done by digging a trench in the ground and simultaneously mixing the ground in situ with a binder. Next may be a further operation for excavating a volume of ground adjacent to the untreated wall so as to uncover a surface of the untreated wall. Following that may be a further operation for treating the untreated wall during which a protective treatment substance comprising a polymer substance is applied to the surface that was uncovered in such a manner as to obtain a retaining wall of a thickness that is substantially equal to the thickness of the untreated wall.

Abstract: The disclosure provides a system and method of reducing vortex induced vibration (VIV) with a plurality of tangentially disposed side plates having an open space on both faces transverse to a current flow of water. The side plates cause water separation around the plates with transverse VIV movement of the platform caused by the current flow against the platform, and the tangential side plates resist the VIV movement of the platform from the current. The side plates can be disposed tangentially around a periphery of an open truss structure below the hull of a spar platform. In another embodiment, the tangential side plates can be disposed tangentially away from a periphery of a hull to form a gap with an open space between the plates and the hull.
