Wagenborg Offshore has been awarded a 6-year contract by Nederlandse Aardolie Maatschappij (NAM) and SHELL UKExploration & Production (Shell UK)) for the provision of a second walk-to-work vessel. NAM and Shell UK work together in combined business unit on the gas production on the Southern Northsea. The vessel will support its offshore operations. This long-term contract was signed November 13 th by the directors of the companies. The so-called ‘Walk-to-Work Emergency Response and Rescue Vessel’ (W2W ERRV) will operate as a standby and support vessel for inspection and maintenance of the unmanned platforms in both Dutch and British waters.

Wagenborg chooses PX121 Ulstein design

For the provision of the W2W ERRV vessel to NAM and Shell UK, Wagenborg and Ulstein have signed an agreement for the delivery of a standard ‘PX121 Platform Supply Vessel’ (PSV). Built according the Ulstein Accommodation Standard, the PX121 has gained excellent feedback from the offshore industry due to a favourable combination of fuel-efficiency and load capacity. The PX121 is particularly suited for a conversion to other types of services, such as walk-to-work or Emergency Response and Rescue, without comprising her outstanding Dynamic Positioning performance.

Economic boost for the North of Netherlands

On the Dutch shipyard Royal Niestern Sander in Delfzijl, approximately 80 employees will be working on the conversion of the PX121 from a PSV into a W2W ERRV vessel. The PX121 will be equipped a.o. with an additional accommodation module, motion compensated gangway and motion compensated crane to comply the requirements of NAM-Shell. The vessel will be converted in 16 weeks by Royal Niestern Sander and is expected to be delivered to Wagenborg Offshore March 2018. The vessel will start operations in Q1 2018.

Producing natural gas offshore

By producing natural gas offshore NAM and Shell UK face major challenges to execute offshore operations as safe and efficient as possible and increase the effectiveness of offshore maintenance activities to reduce costs. Modern offshore production platforms are smaller and normally unmanned without 'helicopter deck', resulting in a need for Walk-to-Work vessels. With Walk-to-Work vessels offshore activities can be supported more safe, efficient, effective and productive, as already proven by the successful Walk-to-Work vessel Kroonborg. The additional W2W ERRV vessel will be positioned in a similar way as Kroonborg and, in addition, will also comply with the ERRV (Emergency Response and Rescue Vessel) Class B guidelines.
