The Genesis of the Marine Pilot Programme

​

During summer, 2025, Pherousa officially initiated its Marine Pilot Programme, a landmark effort to translate laboratory innovation into marine reality. The programme follows the significant achievement of obtaining Approvals in Principle (AiP’s) from two major classification societies – ABS (American Bureau of Shipping) and DNV (Det Norske Veritas) – in the first quarter of 2025.

​

From Prototype to Marine Integration

The initial 10kW prototype, which proved the underlying technology, is now being scaled to a modular marine pilot with a power output of 250+ kW. Marinizing the Pherousa concept involves designing for reliability, safety, and operability within the challenging marine environment.

​

The journey from concept to deployment is characterized by systematic scaling and engineering adaptation. Once the Marine Pilot is tested & approved, the technology can be scaled to any size and thus commercialized.

Pilot Installation and Specifications

Central to the programme is the installation of the pilot system on a “host ship.”  This can be any vessel currently trading and in a «semi-international» trading pattern. Pherousa is working on mapping suited candidates

​

The implementation involves:

​

• Footprint: The entire installation is estimated to occupy one 40 ft container, supplemented by an additional tank for ammonia storage.

• Operational Role: The system will be designed to produce electricity and supplement the vessels switchboard during all relevant service conditions.

• Type Approval: To ensure compliance and facilitate future adoption, the system will seek formal type approval from relevant classification societies once operational performance is validated.
