Propulsion, automation selected for DP2 multipurpose workboat
Thrusters, cooling units, dynamic positioning and alarm systems have been contracted for an ultra-low-emissions workboat being built to support marine construction and offshore projects
Van Wijngaarden Marine Services has contracted Kooiman Marine Group to build a shallow-draught workboat in the Netherlands to expand its fleet supporting marine construction and shallow-water renewable projects.
Kooiman is building multipurpose vessel Rijnstroom to its own design, with Dutch machinery and automation.
This 47-m vessel will have a beam of 16 m, a draught of just 2.6 m, dynamic positioning to DP2 class, accommodation for 27 crew members, and heavy-duty deck equipment for towing, anchor handling, dredging support, subsea construction and maintenance, and to deploy navigation aids.
Deck machinery will include two deck cranes with an outreach of 21 m and holding capacity of 17 tonnes, and an anchor-handling, towing winch with a 220-tonne pull and 250-tonne hold.
Its hybrid diesel-electric propulsion will be compliant with IMO Tier III emissions standards and ultra-low-emissions vessel class notations.
Propulsion will consist of two Veth Z-drives of type VZ-900, two Veth VT-400 tunnel thrusters and a compact jet of type CJ-1400V.
Design, production and testing of the thrusters and control systems will all be carried out at Veth’s facilities in Papendrecht, the Netherlands.
Praxis Automation will supply the vessel’s DP2 and alarm monitoring and control systems, while MEZ will be the system integrator at Kooiman’s shipyard.
NRF will supply 16 box coolers for this newbuild to cool the main engines, auxiliary engines, and additional engineroom equipment. These coolers will be designed to meet the specific operational requirements of Rijnstroom and will be equipped with ultrasonic technology to prevent marine biofouling while reducing maintenance requirements.
In addition, Van Wijngaarden Marine Services has contracted Neptune Marine to build a DP1-class shallow-draught workboat, with IMO Tier III-compliant propulsion, at its facilities in the Netherlands.
Maasstroom will be constructed to Neptune’s EuroCarrier 2712 design with a large working deck, accommodation for up to 12 personnel, a four-point mooring system and an A-frame. Delivery is scheduled for September 2026.
In January, Neptune secured a contract from the Royal Netherlands Navy to build three medium-sized harbour and seagoing tugs. They will be deployed for towing and mooring operations within the naval harbour of Den Helder, and will also support fuel supply activities and emergency response.
Following their delivery in 2027, Neptune will provide two years of maintenance support to the Navy for these vessels.
The 28th International Tug & Salvage Convention, Exhibition & Awards will be held in Gothenburg, Sweden, in association with Caterpillar, 19-21 May 2026. Use this link for more details of this industry event and the associated social and networking opportunities.
