摘要: A submerged or partially submerged structure includes one or more non-cylindrical support columns interconnected at the lower ends thereof by horizontally disposed pontoons. The support columns include one or more strakes mounted thereon. The columns and strakes contribute to the stability of the structure during free floating operations and installation by reducing vortex induced motion.

摘要: A tension leg platform includes a deck supported on the upper ends of three or more columns interconnected at the lower ends thereof by horizontally disposed connecting members. The columns are battered inwardly and upwardly from the platform base to the deck. Tendons connected at the columns anchor the platform to the seabed. The footprints of the base of the battered columns and the tendons are larger than the footprint of the deck supported on the upper ends of the columns.

摘要: An offshore platform includes a buoyant hull comprising three or more interconnected pontoons and a plurality of support columns. The support columns support a deck or structure that supports equipment and/or payloads above a water surface. The support columns extend upwardly from respective ends of the pontoons to the deck or structure supported above the water surface. Anchoring members anchor the platform to the seabed.

摘要: A fairing for the reduction of vortex-induced vibration and the minimization of drag about a substantially cylindrical element immersed in a fluid medium. The fairing also eliminates the galloping phenomenon typically associated with a teardrop-shaped fairing. The fairing having a U-shaped cylindrical shell with opposing edges defining a longitudinal gap and parallel fins extending outwardly from the opposing edges of the shell, the parallel fins being positioned so as to reduce vortex-induced vibration, minimize drag and to eliminate the galloping phenomenon on the cylindrical element. Preferably, the length to diameter ratio of the fins is 1.5 to 2.50.
摘要翻译: 用于减少涡流引起的振动的整流罩以及围绕浸在流体介质中的基本圆柱形元件的阻力最小化。 整流罩也消除了通常与泪珠形整流罩相关的疾驰现象。 具有U形圆柱形外壳的整流罩具有限定纵向间隙的相对边缘和从壳体的相对边缘向外延伸的平行翅片,平行翅片被定位成减少涡流引起的振动,最小化阻力并消除疾驰 圆柱形元件上的现象。 优选地,翅片的长径比为1.5至2.50。
