Everllence’s first ammonia-burning engine built by licensee Engine & Machinery of Hyundai Heavy Industries (HHI-EMD) in South Korea has passed its factory acceptance test (FAT). The dual-fuel Everllence B&W 6G60ME-LGIA (-Liquid Gas Injection Ammonia) type is slated for a vessel for Singapore-based, Eastern Pacific Shipping (EPS).
The vessel is part of a series that is currently under construction at HD Hyundai Heavy Industries (HHI) in Korea. These very large ammonia carriers (VLACs) – with first delivery scheduled from October 2026 – will be the first in the world to be equipped with the Everllence 6G60ME-LGIA ammonia engines. The engines also come equipped with high pressure selective catalytic reduction (HPSCR) technology.

FAT
An FAT is a quality-assurance process where newly manufactured equipment is rigorously tested to ensure it meets all specifications, making it ready for installation and operation on the customer side.
Ole Pyndt Hansen – Senior Vice President, Head of Two-Stroke R&D, Everllence: ‘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. The speedy execution of this FAT is just the latest step in what we anticipate will be a largely seamless journey from lab to ocean.’

Extra safety features
Everllence first introduced the ME-LGIA at a two-day event in Copenhagen in November 2025. Using the Diesel principle and the well-known, dual-fuel liquid gas injection concept, the engine has many of the same merits as Everllence’s existing ME-LGIM and ME-LGIP units that, respectively, run on methanol and LPG.
The new engine also has many, extra safety features such as containment systems, sensors, system ventilation and double-walled piping developed especially for ammonia’s characteristics as a fuel.
Everllence reports that the full sales release of the ME-LGIA will initially feature G50, S50, S60, G60, G70 and G80 bore sizes; retrofit options will also be made available as part of the full sales release.
