摘要： A method and apparatus for entrenching an elongated pipeline and the like uses a trenching apparatus having a trench cutting assembly which is detachably connected to a sled base. A floating vessel has means to control positioning of the trenching apparatus, including means to raise and lower, and to connect and disconnect, the trench cutting assembly and the sled base. Several methods and apparatus are disclosed for raising and lowering the trench cutting assembly while leaving the sled base positioned on the bottom of the body of water, straddling the elongated pipeline. In each embodiment, the cutting means may be lifted on board the vessel for maintenance and/or repair, leaving the sled base in position relative to the pipeline. Means are provided for abandoning the sled base at the entrenching site and returning later to lower the trench cutting assembly into its operational relationship with the sled base.

摘要： An apparatus and method for trenching beneath an elongated member lying on the bottom of a body of water are disclosed. The apparatus has a movable frame member, at least one cutting assembly, an assembly support means connected to the frame member for supporting each cutting assembly and for moving each cutting assembly at least in a laterally directed plane, and a spoil removal system. Each cutting assembly comprises at least two actuatable cutting tools which are driven for cutting movement relative to cutting tool axes. The cutting tool axes, for each cutting assembly, define an assembly cutting plane and means are provided for rotating the assembly cutting plane relative to the laterally directed plane, thereby, varying the cutting swath of the associated cutting assembly. In one aspect the method of the invention is directed to trenching from both sides of and beneath the elongated member to be buried. In another aspect, the method is directed to trenching from one side only, or from one side of and then from the other side of and beneath the elongated member to be buried.
摘要翻译： 公开了一种用于在位于水体底部的细长构件下方开挖沟槽的装置和方法。 该装置具有可移动框架构件，至少一个切割组件，连接到框架构件的组件支撑装置，用于支撑每个切割组件并且用于至少在横向指向的平面中移动每个切割组件，以及弃土移除系统。 每个切割组件包括至少两个可致动的切割工具，其被驱动以相对于切削工具轴线进行切割运动。 对于每个切割组件，切割工具轴线限定了组件切割平面，并且提供了用于相对于横向指向的平面旋转组件切割平面的装置，从而改变相关联的切割组件的切割条。 在一个方面，本发明的方法涉及从要被埋设的细长构件的两侧和下面开沟。 在另一方面，该方法仅针对从要被埋设的细长构件的一侧开始，或从一侧开槽，或从另一侧开槽。

摘要： A process for starting and laying a submergible elongate structure, such as a pipeline, upon the bed of a body of water from a marine vessel, while controlling the bending configuration thereof. The method includes the steps of tensioning a flexible cable between a marine vessel and a submerged hook-up facility, progressively suspending portions of a pipeline from the tensioned cable by means of spaced hangers, and extending the pipeline toward the submerged facility. The process may be employed solely to initially start to lay a submergible elongate structure or the process may be employed to both start to lay a submergible elongate structure and to subsequently lay a submergible elongate structure.
摘要翻译： 一种用于在控制其弯曲构型的同时从海洋容器在水体的床上启动和铺设诸如管道的潜水细长结构的方法。 该方法包括以下步骤：在船舶和浸没式连接设施之间张紧柔性缆索，通过间隔的悬挂架将管道的一部分从张紧的缆索逐渐悬挂下来，并将管道延伸到浸没设备。 该方法可以仅用于最初开始铺设浸没式细长结构，或者该方法可以用来开始铺设潜水的细长结构并随后铺设潜水的细长结构。
