RINA awards first AiP for energy-harvesting ship

DRIFT Energy, a Bath-based deep tech startup, has officially secured an Approval in Principle (AiP) from classification society RINA for its innovative energy-harvesting vessel design. Presented to CEO Ben Medland by RINA’s Patrizio Di Francesco, this milestone marks a significant shift toward sustainable maritime propulsion. By utilizing advanced hydro-foiling technology to generate green hydrogen at sea, the vessel aims to revolutionize how the merchant navy approaches renewable energy integration, setting a new benchmark for future zero-emission shipping operations.

The certification process for this novel design aligns with stringent international maritime standards, specifically addressing the safety and stability requirements outlined in SOLAS Chapter II-1 regarding ship construction and machinery. Furthermore, the vessel must comply with the International Code of Safety for Ships using Gases or other Low-flashpoint Fuels (IGF Code) to ensure the safe handling of hydrogen. For compliance departments and technical superintendents, this AiP confirms that the design meets the rigorous risk-based assessment criteria necessary for future flag state registration and operational deployment.

Chief engineers and second engineers will need to familiarize themselves with the integration of energy-harvesting systems and hydrogen bunkering procedures as these vessels enter the fleet. Unlike traditional diesel-electric propulsion, these systems require specialized knowledge of fuel cell maintenance and renewable energy management. Officers must prepare for updated certification requirements and safety protocols, as the transition to autonomous, wind-powered hydrogen production will fundamentally alter daily engine room operations and technical maintenance schedules for the next generation of seafarers.
