ABERDEEN, UK — Maritime Developments (MDL) has supported DEME with a project to replace a damaged cable on a wind farm in the southern North Sea.
The company’s work scope covered transpooling of array cables between the shore and the vessel, using its portable flex-lay equipment and field service personnel.
Operations took place at a quayside facility in the Netherlands. During Phase 1, a new 2,400-m long, 33-kV submarine array cable was loaded onto the carousel on DEME’s support vessel Viking Neptun, which then sailed to the wind farm to recover the damaged 2,200-m cable and perform the replacement operation.
Afterward, the vessel returned to port where MDL transpooled the excess length of the new cable onto a storage reel followed by spooling of the damaged cable on top of the new cable for shipment.
For this task, the company deployed a two-track tensioner, a 3-m overboarding chute, cable trolley system and under-rollers. The TTS-2/90 series tensioner’s 3.35-m track contact length is said to allow a higher line-pull to be maintained by applying less squeeze to the product, the squeeze load being spread over a larger area.
