20110188940 | METHOD FOR THE CONSTRUCTION OF A LONG PIPELINE - 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. | 08-04-2011 |
20110226764 | MOBILE UNIT FOR THE CONSTRUCTION OF ELONGATED TUBULAR BODIES - The invention concerns a mobile unit for the construction of an elongated tubular body comprising an elongated, tubular inner hollow core, an elongated, tubular inner casing and an elongated, tubular outer casing, the inner casing surrounding the hollow core, the outer casing surrounding the inner casing, the outer casing comprising one or more layers, each layer consisting of one or more helically wound metal strips, the inner casing and the outer casing as well as any layers in the outer casing being bound to each other by an adhesive, which elongated body has been made by a process comprising constructing the elongated inner casing, providing one or more metal strips, winding the one or more metal strips helically around the inner casing, providing adhesive or a curable adhesive precursor and applying it between the casings and the layers, followed by curing the adhesive precursor when present, the mobile unit comprising a multitude of detachably connected containers ( | 09-22-2011 |
