Newlight's retrofit package for two- and four-stroke main engines completed a RINA-approved, four-day Factory Acceptance Test. The program exercised the hydrogen injection sequence end to end, including predictable system-state transitions, continuous thermal and emissions monitoring, load tracking, and immediate changeover between hydrogen and conventional fuel.
The test also verified the system's safety layers: fire and leak detection, local and remote emergency stops, and calm, proportional responses to alerts. RINA reported that the package's detection, ventilation, segregation, and shutdown functions aligned with the safety goals of the IGF Code.
The package was designed and built to the IGF Code and validated to RINA Class Rules for hydrogen-fuelled ships. Factory acceptance confirms the package at system level; it does not replace vessel-specific review. RINA identified Harbor Acceptance Testing, under its supervision during commissioning of the first vessel, as the next approval stage.
