    • A floating production and storage facility (FPS) or "floating atoll" comprises a very large tension leg platform (TLP) having a regular or irregular polygonal horizontal cross-section (including a circle) and having a centralized opening (moonpool) therethrough. The floater has wave transparent attributes, stanchions sited interior of the moonpool adapted to receive risers and maintain the risers within a limited horizontal zone with reference to the vessel while allowing vertical freedom of motion with reference to the vessel. It also has risers sited in the stanchions and connected to the bottom of the body of water upon which the TLP floats. The risers have sufficient buoyancy means below but near the surface of the water to tension the risers into vertical position, and can have additional buoyancy means distributed over much of their length. The floater can have large oil storage means, and can be moored by lateral mooring as well as the TLP tendons.
    • 浮动生产和储存设施(FPS)或“浮动环礁”包括一个非常大的张力腿平台(TLP),其具有规则或不规则的多边形水平横截面(包括一个圆),并且具有通过其中心的开口(月球)。 浮子具有波浪透明的属性,位于适于接收立管的月球内部的支柱,并且相对于船只允许垂直的运动自由度,相对于船舶将提升管维持在有限水平区域内。 它也有立管位于支柱中,并连接到TLP浮起的水体的底部。 立管具有足够的浮力装置,但靠近水表面,以将立管张紧到垂直位置,并且可以具有分布在其大部分长度上的附加浮力装置。 浮子可以具有大的储油装置,并且可以通过侧向系泊以及TLP腱系泊。

    • In a Tension Leg Platform, the common practice is to locate the well and anchor templates on the sea floor. This practice results in unequal lengths for the mooring elements which extend to the base of the floating structure and the well risers which extend to a well deck level which is elevated above the base of the floating structure. As a consequence, complicated tensioning systems having an extremely long stroke may be required for the well risers. The present invention provides for a well template which is elevated above the anchor templates at a level which equalizes the lengths of the mooring elements and the well risers. The well and anchor templates are constructed in a unitary structure to facilitate installation and assure proper spacing of the templates with respect to each other. In preferred embodiments of the invention, subsea storage is provided as well as curved conductors which facilitate angular deviation of the wellbores away from the template and J-tubes for the pull-in of subsea flowlines.
    • 在张力腿平台中,通常的做法是将井和锚模板定位在海底。 这种做法对于延伸到浮动结构的基部的系泊元件和延伸到升高到浮动结构的基部之上的井甲板水平面的井立管,导致不相等的长度。 因此,井立管可能需要具有非常长的冲程的复杂的张紧系统。 本发明提供了一种井模板,其在锚定模板上方以等于系泊元件和井立管的长度的水平升高。 井和锚模板以单一结构构造以便于安装,并确保模板相对于彼此的适当间隔。 在本发明的优选实施例中,提供了海底存储以及弯曲的导体,其有助于井筒离开模板的角度偏离和用于海底流线的拉入的J型管。
