摘要： A floating offshore platform is disclosed with one or more extension plates fixedly coupled to one or more pontoons on the offshore platform and extending from the pontoons. As the floating platform moves, the pontoon-coupled extension plates separate the water and cause drag on the platform. The water moving with the extension plates also increases the dynamic mass. The added drag and dynamic mass increases the natural period of the motion away from the wave excitation period to minimize the wave driven motion compared to a platform without the extension plates. The extension plates can be coupled to the pontoons during fabrication at the yard directly or through frame members. The extension plates generally are generally located inclusively between the top and bottom elevations of the pontoons, and therefore do not significantly reduce the clearance between the seabed and the hull at the quayside.

摘要： 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.

摘要： The present disclosure provides a system and a method for efficiently converting the structure of a drilling floating platform into a structure for a production floating platform. A riser support module can be coupled to a topsides of the drilling floating platform and suspended below a moonpool or other opening through the topsides to support risers and their respective riser pull tubes, if any. The riser support module can be prebuilt and installed as a unit for example at a quayside.
