摘要： A mooring system that uses combination traction winch/windlass units is improved by adding an additional fairlead at each combination unit location and by increasing the strength of existing combination units, their foundations and the foundations of associated equipment such as fairleads and turning sheaves. By these relatively simple upgrades, the mooring capabilities of the system can be economically augmented in those situations where additional lines are desired, such as in areas subject to tropical revolving storms. Normal mooring, when there is no threat of hurricanes, has the anchor and chain attached to the floating structure by wire deployed from the traction winch. When storm season threatens, additional anchors attached to chain run over the windlass can be added, allowing the number of lines to be doubled. The additional anchors can be installed if the floating structure is conventionally moored or if it is attached to pre-set moorings.
摘要翻译：通过在每个组合单元位置添加一个额外的通道，并通过增加现有组合单元，其基础以及相关设备（如弹道和转向轮）的基础，实现使用组合牵引绞车/起落架单元的系泊系统。通过这些相对简单的升级，系统的系泊能力可以在需要额外线路的情况下经济地增加，例如在受热带轮流风暴影响的地区。正常的系泊系统，当没有飓风的威胁时，通过从牵引绞盘部署的电线将锚链和链条连接到浮动结构。当风暴季节受到威胁时，可以添加附加到锚链上的附加锚杆，从而可以增加线路数量的倍数。如果浮动结构通常是系泊的或者如果它连接到预设的系泊系统上，则可以安装附加的锚。

摘要： The vessel comprises a pair of laterally spaced elongated hulls having a pair of upstanding columns at opposite ends thereof supporting a working platform and a drilling mast in spaced relation above the hulls. The hulls buoyantly support the vessel in a low draft in-transit floating condition with the hulls having freeboard. The hulls have ballast compartments to submerge the hulls and portions of stabilizing columns such that the waterline lies intermediate the height of the columns with the platform and drilling mast elevated above the waterline. The columns stabilize the vessel in the high draft condition and the number, cross-sectional area and configuration of the columns, the weight distribution of the vessel and the geometry of the submerged hulls and portions of the columns are such that the vessel obtains motion minimizing characteristics in the high draft condition. Various features include hydrostatic and geometric properties wherein the ratio of the righting moment about the pitch axis to the righting moment about the roll axis in high draft condition is within a range of 1.0 to 1.3 while the ratio of vessel length to width lies within a range of 1.2 to 1.5; a natural period in heave in a range of 16-18 seconds; and a heave response amplitude operator in a range of about 0.35 to 0.60 in the range of waves of 10-14 seconds.
摘要翻译：船舶包括一对侧向间隔的细长船体，其在其相对端处具有一对直立柱，其支撑在船体上方的间隔关系的工作平台和钻桅杆。船体在船体处于干舷的情况下，在低通风条件下浮起来支持船只。船体具有压载舱，以淹没船体和稳定塔的部分，使得水线位于塔的高度之间，平台和钻桅杆升高到水线之上。柱在高吃水条件下稳定容器，柱的数量，横截面面积和构型，容器的重量分布以及浸没的船体和柱的部分的几何形状使得容器获得运动最小化特征在高吃水条件下。各种特征包括流体静力学和几何性质，其中在高牵伸条件下围绕俯仰轴线的平衡力矩与绕轧制轴线的弯矩的比率在1.0至1.3的范围内，而容器长度与宽度的比率在范围内为1.2〜1.5; 16-18秒范围内的自然时期; 以及在10-14秒的波的范围内在大约0.35至0.60的范围内的起伏响应振幅算子。
