Niestern Sander signs contract for conversion project multipurpose offshore vessel

Royal Niestern Sander has been awarded a contract for the conversion of a multipurpose offshore vessel by Wagenborg Offshore. This custom-made and specialized offshore vessel will support subsea activities and decommissioning works in the southern North Sea.


An existing young PX121 platform supply vessel will be converted into a multipurpose offshore vessel within 34 weeks at the dock location of the shipyard in Delfzijl. During this period, dozens of local employees will work on the innovative conversion of the ship, which will give an impulse to regional employment. The vessel will be equipped with an additional accommodation module for 20 people. Also, an active heave-compensated crane will be installed to comply with all customer requirements. The ship will also have an Emergency Response and Rescue Vessel (ERRV) class C notation enabling the vessel to perform emergency response and rescue duties. In Q3 2023 the vessel will be christened and the name will be revealed, after which it will commence its services on the Southern North Sea.

Market leader

With various delivered specialized offshore vessels, Royal Niestern Sander 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 the shipyard 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.
