Abstract: A method of joining a first pipe section (109) to a second pipe section (111), for example during J-lay of an undersea pipeline, is described. The method includes positioning the two pipe sections (109, 111) in an end-to-end configuration to define therebetween a joint to be welded (115), measuring the degree of alignment of the pipe sections (109, 111) when they are in the end-to-end configuration in a position ready for welding, ascertaining the relative movement required of the pipe sections (109, 111) in order to improve their alignment, effecting the relative movement so ascertained, and welding together the two pipe sections (109, 111). The method may include the use of geometric data of the end of the pipes in order to ascertain the relative movement required of the pipe sections. A control unit may be used to calculate, using such data, a target orientation that lines up the pipe sections. The measuring step may be performed using, for example, a laser (123) or a camera (223) and backlight (225).

Abstract: A method of S-laying a pipeline from a vessel (103) is disclosed. A stinger (104) extends away from an end of the vessel (103) and the pipeline passes over the stinger (104) as it is laid from the vessel (103). The inclination of the pipeline to the horizontal increases as it passes along the stinger (104) and after it leaves the stinger (104) until it reaches an inflection point beyond the end of the stinger (104) at which the inclination of the pipeline to the horizontal is at a maximum. The inclination of the pipeline thereafter reduces until it touches down on the seabed. The method includes providing guides on the stinger (104) that limit lateral movement of the pipeline relative to the stinger (104) and moving the vessel (103) and the stinger (104) during S-laying to an orientation in which the longitudinal axis of the stinger (104) is inclined to the path of the pipeline (101) just laid on the seabed. The step of moving the vessel (103) and the stinger (104) comprises rotating the vessel (103) and the stinger (104) about a vertical axis passing through or adjacent to the inflection point.
