Greenpeace – The vision
The new Greenpeace vessel, currently in build at Freire Shipyards in Vigo, Spain, is scheduled to enter operation in 2027. Designed by Dykstra Naval Architects, the ship combines advanced sail propulsion with advanced onboard energy systems to significantly reduce operational emissions from launch and become completely fossil fuel free as soon as supply chains and logistics allow.
At the centre of the concept is the integration of a commercial DynaRig system, delivered by Southern Spars.
The DynaRig represents a tried and tested wind propulsion architecture capable of delivering propulsion levels comparable to high engine horsepower, but importantly without emissions. Unlike many emerging concepts, the system is available today and can be integrated into commercial vessels with a clear economic case.
The rig incorporates modern composite structures along with automation tailored to the commercial maritime environment along with a control system designed for continuous operations.
Automation and Control
The system is fully automated, with sail deployment and trimming managed through integrated control systems. This allows centralised operation, reducing crew workload while maintaining safe and repeatable sail handling.
Operational Performance
The rotating free-standing masts and square sails are designed for predictable aerodynamic behaviour and reliable power generation across a wide range of conditions. The configuration delivers strong all-round sailing performance, including windward capability comparable to conventional sailing systems, and generating the best all round polars compared to any of the wind power systems available to the market today.
Energy Efficiency
By harnessing wind as a primary propulsion source, the vessel reduces reliance on fossil fuels while maintaining consistent voyage speeds. Combined with battery systems, alternative fuels and onboard renewable generation, the ship is designed to operate with a significantly reduced environmental footprint.
Economic Viability
A key part of the development has been ensuring the system is commercially practical. The DynaRig architecture allows installation with a reasonable capital investment while delivering strong operational returns through reduced fuel consumption and lower long-term operating costs.
Project Vision
The vessel has been designed to support global scientific research, investigations and environmental campaigns while minimising environmental impact. As an ice-class vessel, it will be capable of operating in polar regions and supporting advanced scientific operations including ROV and submersible deployment.
The project demonstrates what can be achieved when wind propulsion, advanced engineering and complimentary alternative energy systems are integrated from the outset.
For the shipping sector, it provides a landmark example of the art of the possible in respect of a realisation of a close to net zero emission operation on a large commercial scale ship that utilises technologies that are available today.
