Wagenborg Offshore has taken its fourth walk-to-work (W2W) vessel into service as Koenigsborg. The converted platform supply vessel is used as a standby and support vessel for inspection and maintenance of unmanned platforms in the southern North Sea.

After the positive experiences with the W2W vessels Kasteelborg and Keizersborg, Wagenborg has once again opted to convert a standard platform supply vessel into this specialist offshore vessel. The DP2 PX121 vessel, previously named Hermit Viking, was designed and built by Ulstein in Norway.

In approximately six months’ time, Royal Niestern Sander shipyard has converted the Koenigsborg by building a dedicated accommodation module, installing a motion compensated gangway, and converting it in accordance with SPS-60 class.

Maintenance with W2W vessels

Oil and gas companies face major challenges to carry out their work as safely and cost-efficiently as possible and to increase the efficiency of maintenance. Offshore platforms are smaller and normally unmanned without a helicopter deck, resulting in a need for W2W ships.

With W2W ships, offshore activities can be supported safer, more efficiently, more effectively and more productively, as the W2W ships Kroonborg, Kasteelborg and Keizersborg have proven. Koenigsborg is used in a similar way and is ERRV certified.


As an Emergency Response and Rescue Vessel (ERRV), the Koenigsborg can be deployed in emergency situations at platforms for rescue work, standby activities, emergency towing or patrol tasks. The ship is equipped with extra facilities on board, such as an infirmary, reception rooms, a decontamination room, a recovery room and extra sanitary facilities. Koenigsborg is also equipped with a daughter craft and a fast rescue boat, so that rescue activities can also be carried out in bad weather.

The 4065 DWT Koenigsborg measures 83.40 x 18.00 x 8.00 metres.
