Everllence has completed the Factory Acceptance Test (FAT) of its first ammonia-fuelled engine, marking a key step towards commercial deployment of the technology.
The dual-fuel B&W 6G60ME-LGIA engine was built by South Korea-based Hyundai Heavy Industries Engine & Machinery Division and is set to be installed on a vessel for Singapore-based shipowner Eastern Pacific Shipping, currently under construction at HD Hyundai Heavy Industries.
The engine will be fitted on one of EPS’s Very Large Ammonia Carriers (VLACs), with the first delivery scheduled from October 2026. These vessels are expected to be the first globally to operate with Everllence’s ME-LGIA ammonia engine.
An FAT is a quality assurance process that verifies newly manufactured equipment meets all specifications before delivery and installation.
Ole Pyndt Hansen, Senior Vice President and Head of Two-Stroke R&D at Everllence, said: “This is a huge milestone that places our ammonia engine on the very brink of its commercial debut. This engine sets new benchmarks in zero-carbon propulsion and digitally connected performance, and has attracted great interest since development began.”
He added that the rapid execution of the FAT reflects steady progress from development to deployment as the industry seeks scalable zero-carbon solutions.
The ME-LGIA engine, first introduced in Copenhagen in November 2025, is based on the diesel combustion principle and Everllence’s liquid gas injection platform. It builds on earlier dual-fuel designs capable of running on methanol and LPG, while incorporating additional safety systems tailored to ammonia’s characteristics, including containment systems, sensors, enhanced ventilation and double-walled piping.
He added that the result follows an intensive three-year testing programme with safety as the primary focus.
Everllence said initial commercial availability of the ME-LGIA will cover multiple bore sizes, with retrofit options also planned as part of the rollout.
