The most sustainable workboat in the market

Acta Marine has announced that in the summer of 2021, the newest addition to its fleet will be delivered. The vessel, to be named “Coastal Crown” will be the most sustainable workboat in the market. 

The 36-meter-long vessel will be an ultra-shallow draft Multicat-type, equipped with Tier III engines to lower NOx emissions with 73%. She will also be equipped with a 300kWh battery-hybrid pack for both propulsion and the ship’s accommodation, resulting in up to 15% reduction on fuel and CO2 emissions. Furthermore, armed with DP2, accommodation for 19 persons, 30 tons bollard pull and an operating draft of less than 2.0 meters, “Coastal Crown” will be a future proof asset on the international workboat market.

The vessel is currently under construction at shipyard Bijlsma Wartena in the Netherlands. The investment is being supported by a Sustainable Shipbuilding Subsidy from the Netherlands’ government.

Tjeerd-Wiebe Bijlsma, Managing Director of shipyard Bijlsma Wartena says: “We are very pleased that Acta Marine returned to Bijlsma Wartena for this newbuilding workboat, after having delivered other newbuilt vessels in the past decade. The excellent cooperation between all companies, and with our key suppliers, enables the innovative Coastal Crown to be designed and built at the highest industry standards.”


Acta Marine is an independent maritime service provider based in the Netherlands. The company owns and operates more than 30 coastal- and offshore support vessels. These vessels are being deployed all around the world, mainly on projects in the industries Offshore Energy and Dredging & Coastal Infrastructure. With this new vessel, Acta Marine will be able to support its clients to include more sustainable workboat solutions in commercial offerings and projects.


Conoship International has been involved in the basic en detailed design for this vessel.
