    摘要： Methods of reel-laying a mechanically lined pipe (MLP) are described. These include the steps of: spooling the MLP (12) onto a reel (10) in the complete or substantial absence of internal pressure above ambient pressure in the MLP; spooling off the MLP from the reel; aligning and straightening the spooled off MLP, in the complete or substantial absence of internal pressure above ambient pressure, to provide an MLP for laying; and/or the steps of: spooling the MLP (12) onto a reel (10) resulting in the formation of wrinkles in the spooled MLP; spooling off the MLP from the reel; aligning and straightening the unspooled MLP to provide an MLP for laying having wrinkles

    摘要翻译： 描述了铺设机械衬里管（MLP）的方法。 这些包括以下步骤：在MLP中完全或基本上不存在高于环境压力的内部压力时将MLP（12）卷绕到卷轴（10）上; 从卷轴上取下MLP; 在完全或基本上没有内部压力高于环境压力的情况下对准和矫直MLP，以提供铺设的MLP; 和/或步骤：将MLP（12）卷绕到卷轴（10）上，导致在假脱卷MLP中形成褶皱; 从卷轴上取下MLP; 对准未矫正的MLP，以提供MLP，使皱纹<4毫米高，如果有的话，在执行用于检查线的流体密封性的水压试验的情况下去除皱纹。 通过最小化皱纹的尺寸和/或特别选择MLP的衬垫，本发明的方法允许实现更安全，更快的卷绕和卷绕以提供更安全，更快速和更经济地铺设MLP。

    摘要： A method of installing an In-Line Structure (ILS) to a fluid-filled pipeline extending from a reel, over an aligner, and through a lay-tower during offshore reeling, the pipeline having an oblique part from the reel to the aligner, and a vertical part from the aligner through the lay-tower, including at least the steps of: (a) draining fluid in the fluid-filled pipeline from the vertical part of the pipeline to create a drained portion of the vertical part of the pipeline up to and around the aligner; (b) cutting the pipeline at or near the draining of step (a) to create upper and lower open ends of the pipeline; (c) installing the In-Line Structure to at least the upper open end of the pipeline; (d) locating a vent hose through a vent port in the In-Line Structure; (e) adding fluid into the drained portion of the pipeline and venting air from the drained portion of the pipeline through the vent hose to wholly or substantially fill the drained portion of the pipeline with the fluid.

    摘要： A method of installing an In-Line Structure (ILS) to a flooding fluid-filled pipeline extending from a reel, over an aligner, and through a lay-tower during offshore reeling, the pipeline having an oblique part from the reel to the aligner, and a vertical part from the aligner through the lay-tower, including the steps of: (a) draining the flooding fluid from the vertical part of the pipeline to create a drained portion of the vertical part of the pipeline up to and around the aligner; (b) cutting the pipeline at or near the draining of step (a) to create upper and lower open ends of the pipeline; (c) installing a pig into the upper open end; (d) moving the pig through the pipeline to reach a flooding fluid-filled part of the pipeline; (e) adding flooding fluid into the flooding fluid-filled part of the pipeline to reverse the movement of the pig in step (d) and to wholly or substantially refill the drained portion of the pipeline; and (f) installing the In-Line Structure (ILS) to at least the upper open end of the pipeline.

    摘要： A mechanically lined pipe 100 comprises a host pipe 5 having an inner surface which is lined with a metallic liner 10, the metallic liner 10 having an inner surface which is lined with a polymer liner 110 which presses the metallic liner 10 against the inner surface of the host pipe 5. A method of making the mechanically lined pipe is also disclosed comprising the steps of: (a) providing a mechanically lined pipe having an internal diameter, (b) providing a polymer liner having an outer diameter which is greater than the internal diameter of the mechanically liner pipe, (c) using a roller or die, reducing the outer diameter of the polymer liner such that it is less than the internal diameter of the mechanically liner pipe, (d) inserting the polymer liner into the mechanically lined pipe, and (e) allowing the polymer liner to expand such that it presses the metallic liner against the inner surface of the host pipe. Reeling and unreeling the mechanically lined pipe may be carried out with low internal pressure without the metallic liner suffering from wrinkling. The polymer 110 liner may comprise regular apertures (70, figure 4) such that gases which are able to diffuse through the polymer liner 110 will not become trapped between the polymer liner 110 and the metallic liner 10.
