20m Kelp Harvester

A multi-purpose 20m aquaculture vessel designed with operational efficiency and productivity at its core, supporting demanding offshore and coastal farming operations.

    This 20m aquaculture workboat is engineered for high-productivity operations, offering a substantial 105 m² working deck and a 20-tonne cargo capacity. The layout is optimised for efficient deck handling, equipment deployment, and repeat daily use across a wide range of aquaculture activities.


    Constructed in lightweight, corrosion-resistant aluminium, the vessel delivers long-term durability while reducing maintenance demands in harsh marine environments. The design prioritises stability, payload efficiency, and straightforward operation to support safe and reliable offshore performance.


    To enhance operational efficiency, the vessel can be configured with a range of propulsion options. A hybrid propulsion system, supplied by Volvo and Danfoss, is recommended for improved energy efficiency and reduced emissions. However, the platform remains fully flexible, allowing operators to select conventional, hybrid, or fully electric propulsion systems to suit specific operational and regulatory requirements.


    The result is a commercial aquaculture vessel design focused on productivity, adaptability, and long-term operational value.
