Damen Verolme gets jack-up ready for next gen wind turbines

FEBRUARY 13, 2017 — The 151-metre, self-propelled, DP2 jack-up rig Seafox 5 has left the Damen Verolme Rotterdam (DVR) shipyard following a four-month refit in which the boom of its main crane was lengthened to prepare it for a new contract, along with a range of maintenance and other upgrade works.

Seafox 5 is now equipped to undertake offshore wind projects involving the next generation of larger wind turbines in water depths of up to 65 m.

Delivered in 2012, Seafox 5 is owned and operated by Hoofddorp, Netherlands, headquartered jack-up specialist Seafox BV. At 151 m long and with a breadth of 50 m, she is the largest vessel in the Seafox fleet and has a 1,200 tonne main crane and accommodations for up to 150 personnel. Her arrival at DVR in September last year marked her first time in drydock since her initial delivery.

The primary reason for the visit was to lengthen the main boom of the vessel's Liebherr crane. This will enable the vessel to fullfil an upcoming contract with GeoSea to install 66 six-megawatt wind turbines at the Merkur wind farm off the coast of Germany.

While she was alongside at the shipyard, a series of other works were undertaken including a special periodic survey, testing the jacking system up to 70-m above sea level, renewing the leg guide wear plates, installing a secondary Sormec crane and a repaint.

Seafox 5 Rig manager Alex Eijgenraam said: "Seafox 5's call at the Damen Verolme yard marked a busy and intense period for Seafox 5, its crew and office project team. However, all the scheduled works were completed on time and without incident. Seafox 5 left the yard as good as new and ready for her next assignment for the offshore wind industry. The long experience of Damen Verolme with jack up rigs has contributed greatly to this result."

"It was a tight time frame, but we finished on time and to budget," said Mark Heuders, Project Manager at DVR. "The key to success was, as always, preparation and cooperation, with careful planning of lead times for each activity and regular progress meetings. It has once again been a pleasure to work with Seafox."

Damen has a longstanding relationship with Seafox, whose vessels are regular visitors to both DVR and Damen Shiprepair Amsterdam. The most recent arrival is the Seafox 2, which moored at DVR in the early hours of February 4 for some minor maintenance.
