New agreement advances Sulnox Eco deployment across global fleet

Sulnox Group plc, a new Green Marine partner, has secured its largest commercial agreement to date, significantly expanding the use of its fuel-conditioning product, Sulnox Eco^™, across a global shipping fleet.

The agreement with Eastern Pacific Shipping ("EPS") will widen deployment across its fleet over the next four years, increasing use from around 30 vessels to more than 50. It includes the supply of approximately 1.2 million litres (317,000 gallons) of Sulnox Eco, along with a renewed commitment to ongoing operational validation.

The agreement follows a two-year evaluation process on a diverse fleet, including container ships, bulk carriers, tankers and vehicle carriers. During that time, EPS reported fuel savings of 3% to 5% and observed benefits including cleaner engines, reduced sludge and less visible black smoke.

Further technical testing demonstrated improvements in fuel lubricity of 20% to 23% in Low sulphur marine gas oil (LSMGO), addressing a key challenge associated with lower-sulphur fuels while supporting engine protection and operational reliability. The product has also shown positive results when used with biofuel blends, with testing and operational use indicating benefits in fuel stability, lubricity and engine cleanliness, helping maintain consistent performance across fuel types.

Beyond the supply agreement, the partnership is set to continue as a platform for technical collaboration, with EPS supporting Sulnox’s research and validation programs through fleet-based testing. Through this work, they aim to advance fuel efficiency optimization, emissions reduction, biofuel performance, and maritime decarbonization.
