Conversion of multipurpose offshore vessel for the Southern North Sea on schedule

The 'Aurora Thunder' is currently undergoing a transformation at shipyard Royal Niestern Sander. This offshore supply vessel is being converted into a multi-purpose offshore vessel. This custom-made and specialized offshore vessel will support subsea activities and decommissioning works in the southern North Sea later this year.

In June, the port of Delfzijl set the scene for a complete Wagenborg project during the installation of the additional accommodation unit. This accommodation unit was loaded by means of self-propelled modular trailers on a pontoon and towed to the Wagenborg terminal. Here, two mobile cranes lifted the accommodation on the offshore vessel.


In July, the conversion continued according to plan. As such the vessel was painted in the familiar Wagenborg colours. In addition, the Azipod thrusters were completely overhauled and checked.

Market leader

With five operational specialized offshore vessels on the North Sea, Wagenborg can be considered as one of the market leaders in this offshore niche. All offshore vessels have proven to deliver efficiency and logistical advantages. In 2015 the first walk-to-work vessel ‘Kroonborg’ introduced by Wagenborg and Niestern Sander was awarded ‘Ship of the Year’. In 2018 Wagenborg delivered ‘Kasteelborg’, a walk-to-work vessel after a conversion project. In 2020 the ‘Keizersborg’ and in 2022 the ‘Koenigsborg’ were delivered, both also after a conversion project. The Koenigsborg was awarded ship conversion of the year.
