VIDEO: Boskalis’ Manu Pekka at Work in Worthing

VBMS, a subsidiary of Royal Boskalis Westminster N.V., completed earlier this month the installation of two 16 kilometer-long 150kV HVAC cables for the Rampion offshore wind farm, situated off the coast of Worthing, UK.

To overcome some environmental challenges in this very shallow water, VBMS had to extend the pre-installed landfall HDD’s with duct extensions of approx. 480 meters each.

VBMS utilized Boskalis’ backhoe dredger Manu Pekka to dredge the trenches before installing the duct extensions.

In addition, Boskalis dredged three flotation pits per cable routing to allow CLV Stemat Spirit to reach the location of the end of the ducts.

Following the cable pull-in CLV Stemat Spirit jumped from pit to pit during high tides while laying the cable until it reached deeper water where it could safely remain afloat and resume the remaining cable laying operations.
