On "CSO Deep Blue" Huisman-Itrec supplied a pipe lay system, suitable for the so called "Reel method" as well as for the "J-lay method". However, flexible pipes can also be installed. |
|
|
This pipelay system is one of the largest in the world
and can be regarded as being "highly innovative". Huisman-Itrec
integrated two tensioners in the system with a total capacity of
550 tons. |

The complete process starts at the quay side where the ship loads welded parts of pipe. This pipeline, up to a diameter of 500mm, is wound on a reel ("reel method"). Depending on the diameter, max. 50 km of pipe can be wound on one reel. The Deep Blue is equipped with two of these reels with a diameter of 32m each. On arrival at the oil- or gas field, the pipeline can be "un-reeled". |
|
|
Pipes with a larger diameter, which cannot be reeled,
are installed by the "J-lay
method". Sections of 50m are welded vertically and lowered
to the sea bed. |
|
| Huisman-Itrec designed and built a complete pipelay system for the new built p.l.v. Deep Blue for Technip Coflexip (former CSO, see picture). |
|
| This system is capable of rigid pipe installation using the Reel lay method, installation of flexible pipes and J-lay. The capacity of the system is 550 ton. |  |
| Huisman-Itrec recently designed and built a complete pipelay system for the Seven Oceans for Subsea7. | |
