<p>The invention concerns a method for the construction of a long pipeline using a mobile pipeline producing unit, the mobile unit being able to produce specific lengths of the pipeline, each specific length being a fraction of the length of the long pipeline, the method comprising placing the mobile unit at a first position at the stretch of the projected long pipeline, producing a specific length of pipeline in one direction of the projected long pipeline, producing a second specific length of pipeline in the opposite direction, moving the mobile production unit to a second position at the stretch of the projected long pipeline, producing a third specific length of pipeline in a direction of the long pipeline, producing a fourth specific length of pipeline in the opposite direction, optionally moving the mobile production unit to a further position at the stretch of the projected long pipeline, producing a further specific length of pipeline in a direction of the projected long pipeline, producing another further specific length of pipeline in the opposite direction and optionally repeating this process one or more further times, and connecting all produced specific lengths. The invention further relates to pipelines made according to the method described above and to the use of the pipelines in the transport of gas and/or liquids, especially crude oil and natural gas.</p> |
