Abstract: A trenching assembly lays a continuous pipeline in a trench dug in a bed with uneven bathymetry, the trenching assembly including a trench digging device having a main body; at least four ground contact units, each unit having a height adjustment device, to position each ground contact unit with respect to the main body independently. A trench cutting tool digs in the bed includes a cutting depth adjustment device, for positioning the cutting tool with respect to the main body. A detection device detects bed bathymetry. A control device simultaneously allows cooperation between the detection device, the height adjustment device of each ground contact unit, and the cutting depth adjustment device. A command device cooperates with the control device to adjustment each ground contact unit and the cutting depth adjustment device, to obtain a trench having a height difference lower than a predefined tolerance and a predetermined burial depth.

Abstract: A vessel for laying a pipeline includes a plurality of workstations disposed along a pipelaying path that includes an upstream portion away from a first end of the vessel and a plurality of ramps, includes a first ramp and a downstream second ramp disposed along the pipelaying path, in the region of the first end of the vessel. Each of the plurality of ramps has a first upstream end, a second downstream end, and an adjustable inclination. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel. An external ramp assembly includes ramps that can be pivoted relative to one another and locked in a selected position.

Abstract: A vessel for laying a pipeline includes a plurality of workstations disposed along a pipelaying path that includes an upstream portion away from a first end of the vessel and a plurality of ramps in the region of the first end of the vessel. The plurality of ramps includes a first ramp which is disposed along the pipelaying path, whose inclination is adjustable and which has a first upstream end and a second downstream end, and a second ramp which is disposed along the pipelaying path downstream of the first ramp, whose inclination is adjustable and which has a first upstream end and a second downstream end. The downstream end of the first ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel and the upstream end of the second ramp is positioned inboard of the first end of the vessel and above the bottom of the vessel. An external ramp assembly is provided, including ramps and that can be pivoted relative to one another and locked in a selected position by a locking arrangement.
Abstract translation: 用于铺设管道的容器包括沿着管道铺设路径设置的多个工作站，所述多个工作站包括远离容器的第一端的上游部分和在容器的第一端的区域中的多个斜面。 多个斜坡包括沿着管道铺设路径布置的第一斜坡，其倾斜度是可调节的，并且具有第一上游端和第二下游端，以及沿着第一斜坡下游的管道铺设路径设置的第二斜坡， 其倾斜度是可调节的，并且具有第一上游端和第二下游端。 第一斜坡的下游端位于容器的第一端的内侧并且位于容器的底部之上，并且第二斜坡的上游端位于容器的第一端的内侧并且位于容器的底部之上。 提供外部斜坡组件，包括斜面，并且可以通过锁定装置相对于彼此枢转并锁定在选定位置。

Abstract: A supporting system for a floating unit in shallow water exerts controlled stresses on the floating unit hull and includes supporting structure for the hull. An extendable supporting device operatively connects to the supporting structure and is suitable to support a predetermined weight of the floating unit and load when entirely supported by the extendable supporting device and when the extendable supporting device rests on a bed of a water body. An actuator device connects to the supporting structure and operatively connects to the extendable supporting device for extension or contraction. A control device operatively connects to the actuator device to control the extraction or contraction movement of the extendable supporting device. The system includes at least one hull stress monitoring device operatively connected to the control device. A device to monitor the stress, or load, on the extendable supporting device operatively connects to the control device.

Abstract: A connection assembly for engaging a tubular member underwater to restrain the tubular member from radial movement relative to the connection assembly includes a plurality of pads for engaging the tubular member at circumferentially spaced positions; and a plurality of biasing arrangements, each for biasing a respective pad radially inwardly into engagement with the tubular member; wherein each biasing arrangement includes a pre-loadable, mechanical, compressed spring arrangement for resiliently pressing its respective pad against the tubular member. The assembly need not employ any hydraulic components.
