Newlight completes RINA factory acceptance testing

The system allows existing diesel engines to operate on a blend of hydrogen and conventional fuel, reducing carbon emissions without the need to replace the entire engine.

Designed and built to the International Code of Safety for Ship Using Gases or Other Low-flashpoint Fuels Code (IGF Code) and validated to RINA Class Rules for hydrogen fuelled ships, the RINA-approved FAT verified the package’s safety layers, control and monitoring logic, electrical integration, and engine behaviour under representative duty profiles.

From dock to deep sea, Newlight proved its performance on a four-stroke engine used as genset at a shore-based test and on a two-stroke engine used as main propulsion for a yacht on a sea trial. Greater fuel efficiency and lower emissions were demonstrated while retaining confident control of the engines through real-world sea conditions and load swings, up to full open-water passages. Newlight validated precise hydrogen-blend injection timing, solid load tracking, and continuous thermal/emissions monitoring, as well as instant changeover between conventional fuel and hydrogen to maintain smooth engine performance with no downtime.

Over a focused four-day FAT programme, Newlight exercised the full operating sequence of the hydrogen injection system end-to-end, demonstrating predictable transitions of system states, layered safety in line with applicable regulations, and calm, proportional responses to any alerts. Emergency stops worked from both local and remote controls, and fire and leak detectors were verified to support a safe, easy-to-maintain installation.

In collaboration with lomarlabs, Lomar, and AURELIA, Newlight has said that its solution is now ready for retrofit on a commercial vessel with all interfaces set, layouts optimised, and approved according to class rules.

With FAT complete, Newlight now moves into harbor acceptance testing (HAT), which will be conducted under RINA’s supervision, during commissioning of the first vessel.
