Monday 09.02.2015 the naming ceremony of the Walk-to-Work vessel Kroonborg, our yard no. 848, took place in the port of Delfzijl. This completely new developed Service Operating Vessel (SOV) will be deployed for NAM in assistance for her offshore maintenance activities to unmanned platforms and gas production wells in the Southern North Sea in the upcoming 10 years. Due to a combination of functions and new techniques the Kroonborg is completely unique. The vessel was specially designed after a specific demand from NAM by Royal Wagenborg, shipyard Royal Niestern Sander and NAM. With a dedicated vessel NAM would like to transport her people safely to platforms and to execute offshore operations more efficiently.
Kroonborg, measuring nearly 80 meters, is a workshop, storage, hotel and way of transport. She offers accommodation facilities to 60 persons, including 2 crews of 20 technicians. With this SOV NAM crews will work in two consecutive weeks on multiple platforms. By means of a motion compensated offshore access system, technicians can literally walk to work. A motion compensated crane, using a similar technique, can tranship heavy materials up to 20 tonnes at an outreach of 10 m. (32.5t*2m.). The design, hull shape and Voith Schneider propulsion system of this DP2 vessel enable a smooth seakeeping behaviour at sea. Kroonborg is the first offshore vessel in the world to sail on GTL fuel, a liquid fuel made of natural gas with less emissions than conventional fuels for vessels.
