    • The disclosure provides a semi - submersible offshore platform (5) with columns (6) having an enlarged base (8) on the bottom of each column with pontoons (10) coupled between the columns. The enlarged column base can be at least as high as a height of the pontoon and on at least embodiment can be about 50% of the draft of the platform. The enlarged base can change a current flow shape around the base and columns for lower VIM. An outside corner of the base can be trimmed at an angle. Alternatively, the lower portions of the columns can be extended horizontally outward to form an effectively enlarged base having similar characteristics. In some embodiments, the pontoon volume can be reduced inversely proportional to the base enlargement to have comparable total buoyancy.
    • 本公开提供了一种半潜式海上平台(5),其具有在每列的底部具有扩大的基座(8)的柱(6),其中浮筒(10)连接在列之间。 扩大的柱基可以至少与浮筒的高度一样高,并且至少实施例可以是平台的牵引力的大约50%。 扩大的基座可以改变基部周围的电流流动形状和用于较低VIM的列。 底座的外角可以一定角度修剪。 或者,列的下部可以水平向外延伸以形成具有相似特征的有效扩大的基部。 在一些实施例中,浮筒体积可以与基础扩大成反比,具有相当的总浮力。

    • An extendable draft offshore oil and gas drilling and production platform ("EDP") includes a buoyant deck (12) having a central opening, an adjustably buoyant pontoon (16), and a single, adjustably buoyant column (22). The column is mounted upright on the pontoon, and is vertically movable through the central opening of the deck. The deck (12) is supported on an upper end of the column above a body of water for offshore operations. The pontoon (16), and optionally, the column (22), have compartments with a buoyancy that is adjustable by pumps or sea water ballast and pressurized air. In one embodiment, the compartments can comprise a plurality of tubes. In another embodiment, a lower end of the column may comprise an open truss structure (30). The platform combines the advantages of a SPAR platform with those of a deep draft extendable draft platform.
    • 海上石油和天然气钻井和生产平台(“EDP”)的可延伸起草平台包括一个具有中心开口的浮力甲板(12),一个可调节浮力的浮筒(16)和一个可调节的浮力柱(22)。 立柱直立安装在浮桥上,并可垂直移动穿过甲板的中央开口。 甲板(12)支撑在柱体的上端,用于海上作业。 浮筒(16)和任选的塔(22)具有可通过泵或海水镇流器和加压空气调节的浮力的隔室。 在一个实施例中,隔室可以包括多个管。 在另一个实施例中,塔的下端可以包括开放的桁架结构(30)。 该平台将SPAR平台的优势与深入可伸缩的草稿平台相结合。

    • An extendable draft platform, having a deck and buoyancy columns installed in leg wells in the deck for vertical movement from a raised position to a submerged position, includes a connection arrangement for securing the columns to the deck when the columns are in the submerged position. In the connection arrangement, a plurality of first guide elements near the top of each column is engageable by a plurality of complementary second guide elements secured to the deck around each leg well when the column is lowered to its submerged position. A locking mechanism is operable between the columns and the deck when the first guide elements are engaged with the second guide elements. The first and second guide elements may be configured so that the connection between the deck and the columns may be enhanced by over-ballasting the columns and/or by welding the columns to the deck.
    • 具有安装在甲板的腿部井中的甲板和浮力柱的可伸缩牵伸平台,用于从升高位置到浸没位置的垂直运动,包括用于当柱处于浸没位置时将柱固定到甲板上的连接装置。 在连接装置中,当塔被降低到其淹没位置时,靠近每列的多个第一引导元件可被多个互补的第二引导元件接合,所述多个互补的第二引导元件在每个支柱井周围固定到甲板上。 当第一引导元件与第二引导元件接合时,锁定机构可在列和甲板之间操作。 第一和第二引导元件可以被构造成使得可以通过对柱进行过度压载和/或通过将柱焊接到甲板来增强甲板和柱之间的连接。
