    Abstract: 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.

    Abstract: A mechanically lined pipe including a host pipe having an inner surface which is lined with a metallic liner, the metallic liner having an inner surface which is lined with a polymer liner which presses the metallic liner against the inner surface of the host pipe, as well as to methods of reeling and unreeling the mechanically lined pipe. A method of making a mechanically lined pipe having an internal polymer liner, the mechanically lined pipe including a host pipe having an inner surface which is lined with a metallic liner, the method including 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) 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.

    Abstract: A PIP Trace Heating Connection Assembly A pipe-in-pipe (PIP) trace heating connection assembly in the annulus of a PIP pipeline comprising at least first and second conjoined PIP stalks having inner and outer pipes and the annulus thereinbetween, the first PIP stalk having a first trace heating cable (22) located along its inner pipe, and the second PIP stalk having a second trace heating cable (24) located along its inner pipe, the first and second heating cables have cable ends and heating cable terminals on the cable ends, and a flexible intermediate connecting cable (40) having first and second intermediate terminals secured to, the heating cable terminals of the first and second trace heating cables respectively to form a secured electrical pathway between the first and second trace heating cables. In this way, securing the heating cable terminals with the intermediate connecting cable significantly reduces the time required to form a secured electrical pathway between the trace heating cables of each PIP stalk.
