Description
Field of the invention
The present invention relates to a floating cable factory, for production of for instance subsea umbillicals, comprising a cable production vessel, and a super structure on said production vessel for receipt and combination of single core cables.
Subsea umbillicals are designed for the transmission of power, fluids, electrical and optical control to offshore installations. Subsea production umbilicals include many different components to suit a mix of power and control functions needed offshore and subsea as thermoplastic hoses or steel tubes provide hydraulic valve control functions and low voltage cables are used for communications.
The power cable/conductor is made up of wires of metal and an insulation layer made of either EPR (ethylene propylene rubber) or XLPE (cross-linked polyethylene). The power cables are twisted together into a helix with plastic hoses or steel tubes and fiber optics in a vertical or horizontal bundling machine. The process of twisting enables the composite bundles to be bent much tighter than if the function were straight, enabling the power cable or umbilical to be shipped and installed with greater ease.
A strength member can be added as a steel wire and as a layer of steel wires forming an armor on the outside of the bundle. Fill members as ropes or plastic material can be added to fill the internal gaps and petroleum gels can add water resistance. The outer coiled steel or aluminum layer provides mechanical protection, tensile strength and impact protection.
An outer sheath encases all the other layers. A sheath is frequently made from a continuously extruded thermoplastic material such as polyethylene, which has the physical strength and moisture resistance capabilities.
Most global production facilities utilize horizontal lay up machines. Some few manufacturers utilize vertical machines, mainly so-called EZ production principle or non-helical.
Prior art
WO 2015/112007 A1 discloses a method for manufacturing a subsea pipeline and spooling said pipeline onto a reel or a carousel of a pipe laying vessel at a spool base. The method comprises connecting pipes end-to-end at a pipeline assembly station to form a continuous pipeline stalk. The continuous pipeline stalk is spooled directly from the pipe assembly station onto a floating intermediate pipeline storage device that is adjacent the pipeline assembly station and the stalk is temporarily stored thereon. The pipeline stalk is later spooled from the floating intermediate temporary pipeline storage device onto the reel of the pipe laying vessel. The floating intermediate pipeline storage device is a carousel pipeline storage device which has an annular floating base that is assembled from multiple barges which are interconnected in an annular array and having an above waterline carousel.

Description of preferred embodiments of the invention
A main cable tank 21 with a center turret 5 is placed in a slot 23 of a production vessel 6 with a production tower or super structure 18. The vessel 6 can be a ship, barge, or other floating installation.
Required number of cable supply tanks 22 with feeder turrets 9 is placed in selected positions around the production vessel 6. The cable supply tanks 22 comprises single core cables 20 for production of for instance an umbilical. The cable supply tanks 22 are labeled A,B,C,D,E,F,G,H in figures 2 and 4.
Individual single core cables, hoses or tubes 20 are pulled out of the rotational feeder turrets 9 and over vertical turn wheels 1 in the super structure 18. The single core cables 20 are thereafter led down through a collecting guide 2 with a distribution and turn restrictor wheel 3, and through a rotating pull assembly 4. From the rotating pull assembly 4 the wounded main cable 19 is led through a rotational distribution guide 8 and into the rotating center turret 5 in the main cable tank 21.
The vertical turn wheels 1, the rotational pull assembly 4, the rotational center turret 5, the rotational feeder turret 9, the hose or tube 10 for the single core cable 20, and rotational feeder guide 11 are electronically controlled by one unique control system where all units automatically adjust speed, pull and rotation. Each and every unit is tuned and can adjust itself automatically.
The rotational center turret 5 is placed floating in the main cable tank 21, and can be turning clockwise. The rotational feeder turret 9 can likewise be placed floating in each cable supply tank 22, and can be turning anti-clockwise.
The floating cable factory can also comprise a final product line assembly, as shown in figures 3 and 4. A guide arm 14 guides the main cable 19 out of the main cable tank 21. It is possible that the main cable tank 21 can be omitted and the main cable 19 can be led from the super structure directly to the final product line assembly.
Several pulling units 17 can be used to pull the main cable 19 along the final product line. The final product line assembly further comprises several units, such as extruders 12, gas super cooling 16 and water cooling 15, or other equipment, to prepare and coat the final main cable 19.
After the preparing and finalizing of the main cable 19, the main cable 19 is fed by a guide arm 14 to a turret 13 in a final product export tank 24. The final product export tank 24 is floating next to the production vessel 6. The turret 13 can be placed rotational and floating in the final product export tank 24, similar to the feeder turret 9 and center turret 5.
After the bundling is complete and the main tank 21 with the center turret 5 is filled with the bundled cable/umbilicals 19, the bundled cable 19 will be pulled out of the center turret 5 assisted by the guiding arm 14 and into the extruderline for installing the outer sheet and finally guided 14 into the turret 13 of the floating export tank 24.
The floating export tank 24 can for instance keep more than 4000 ton of final product (cable/ umbilical). This tank 24 can be floated into special modified transport- or installation-ships.
The main cable 19 can as mentioned be an umbilical. An umbilical is a thick, complex and normally reinforced cable wound together of steel pipes and several thinner cables for power, fiber, communication, hydraulics, chemistry, and/or other cables, for surveillance and control of subsea wells. The single cables 20 can thus be any of the latter.
