Abstract: A method of laying conduit at sea from a reel vessel includes the steps of laying conduit, for example pipeline or umbilical, from a first reel which rotates about a first substantially vertical axis. Conduit is laid from a second reel of conduit rotating about a second substantially vertical axis spaced apart from the first axis. A portion of the route travelled by the conduit during the step of laying conduit from the first reel of conduit is substantially the same as a portion of the route travelled by the conduit during the step of laying conduit from the second reel of conduit, for example, the conduit from the second reel may pass around a part of the periphery of the first reel and then follow substantially the same path as previously travelled by the conduit laid from the first reel.

Abstract: A method of abandoning an underwater pipeline on the bed of a body of water from a laying vessel includes the steps of lowering the free end of the pipeline into the body of water and onto the bed of the body of water using a first and second rope, both connected to the free end of the pipeline and extending from the laying vessel to the free end of the pipeline. The method also includes disconnecting the first rope from the free end of the pipeline, once the free end of the pipeline is laid on the bed of the body of water; and rewinding the first rope onto the laying vessel, while the second rope is still connected to the free end of the pipeline.

Abstract: A method of laying a pipeline from a laying vessel into a body of water includes guiding the pipeline along a supporting structure of a laying ramp using a number of guide devices, and acquiring an image of the pipeline, in an acquisition plane crosswise to the axis of the pipeline, at the free end of the laying ramp. The method also includes determining whether the acquired image is within an acceptance range predetermined as a function of the configuration of the supporting structure and the size of the pipeline, and emitting an error signal when the acquired image is not within the acceptance range.
