    • An anchor includes at least one fluke, a shank, and a float. The relative position of the float with respect to the center of gravity of the combined shank and fluke causes the anchor to assume a generally upright orientation quickly once the anchor is dropped in the water. One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank, with the float's center of buoyancy spaced away from the connection to the fluke. Upon being put in the water, the anchor quickly assumes a generally upright orientation, i.e., shank up and fluke tip down. Once in the generally upright orientation, the anchor may gently rock side to side with a pendulum-like action, with the tip of the fluke preferably being the lowest point of the anchor, during its descent to the bottom. When the anchor reaches a soft bottom, the tip of the fluke penetrates the bottom and the momentum of the anchor causes at least a portion of the fluke to bury into the bottom in a generally upright orientation. This setting of the anchor may be achieved in most or all situations without dragging the anchor along the bottom. The anchor is particularly adapted for watercraft where storage space is a concern and for shallow water watercraft.
    • 锚固件包括至少一个吸头,柄和浮子。 浮体相对于组合的柄和吸头的重心的相对位置使得锚固件在水中落下后,锚固体将迅速呈现大致直立的方向。 柄的一端连接到吸头,并且浮子附接到柄的后部,浮子的浮力中心与与侥幸心的连接间隔开。 当被放入水中时,锚固体很快地呈现一个大致直立的方向,即,柄向上并且使得尖端向下倾斜。 一旦处于大致垂直的方向,锚可以以摆式动作轻轻地朝着侧面摇动,其中该杆的尖端优选地是在其下降到底部的锚点的最低点。 当锚固件到达软底部时,吸头的尖端穿透底部,并且锚的动量使得至少一部分flu子以大致直立的方向埋入底部。 可以在大多数或所有情况下实现锚的该设置,而不沿着底部拖动锚。 该锚特别适用于存储空间和浅水船只的船舶。

    • An anchor (10) includes at least one fluke (20), a shank (40), and a float (60). The relative position of the float with respect to the center of gravity of the combined shank and fluke causes the anchor to assume a generally upright orientation quickly once the anchor is dropped in the water. One end of the shank is attached to the fluke and the float is attached to a rearward portion of the shank with the float's center of buoyancy spaced away from the connection to the fluke. When the anchor reaches a soft bottom, the tip (22) of the fluke penetrates the bottom and the momentum of the anchor causes at least a portion of the fluke to bury into the bottom in a generally upright orientation. The fluke preferably includes two forward pointing tines (130), each tine comprising a pointed tip, a wing surface (30), a longitudinal fold (138) extending parallel to the longitudinal axis (25) of the fluke and an outboard surface (136). The wing surfaces are canted with respect to each other and are arranged inward of the respective longitudinal folds.

    • A method and apparatus for replacing an existing looped non-metallic mooring line (20) from a floating anchor handling vessel (10) anchored to the sea floor. The existing looped line (20) extends about a sheave (34) adjacent a subsea anchor means (24) and opposed ends (26) of the looped line (20) are connected to a mounting member (30) on the vessel (10) for securing the ends (26) of the existing mooring line (20). The new replacement line (20A) is attached to an end of the looped existing line (20) and the old existing line (20) is hauled in while the looped replacement line (20A) is payed out from the vessel (10) about the sheave (34) for return to the vessel. The looped replacement line (20A) is disconnected from the old line (20) and the ends of the new replacement line (20A) are secured to a mounting member (30) on the vessel. The existing mooring line (20) is preferably replaced by the anchor handling vessel (10) while a main floating, production, storage and offloading (FPSO) vessel (12) remains moored to the sea floor by the remaining mooring legs or lines.
    • 一种用于从锚定到海底的浮动锚泊处理容器(10)替换现有的环形非金属系泊绳(20)的方法和装置。 现有的环形线(20)围绕靠近海底锚固装置(24)的滑轮(34)延伸,并且环形线(20)的相对端(26)连接到容器(10)上的安装构件(30) 用于固定现有系泊线(20)的端部(26)。 新的替换管线(20A)附接到环路现有管线(20)的一端,并且旧的现有管线(20)被牵引,而环形替换管线(20A)从容器(10) 滑轮(34)返回船只。 环形更换线(20A)与旧线(20)断开连接,新替代线(20A)的端部固定在容器上的安装件(30)上。 现有的系泊线(20)优选地由锚式处理容器(10)代替,而主要的浮式,生产,储存和卸载(FPSO)容器(12)通过剩余的系泊支腿或管线停留在海底。
