• Agreement extends relationship with world’s biggest builder of marine engines and its service division
• Accelleron continues support for HMS as one-stop shop for engine and turbocharger service
• Eco-friendly solutions including Engine Part-Load Optimization to further support decarbonisation of the maritime industry

Accelleron has renewed its service agreement with the world’s biggest engine builder HD Hyundai Heavy Industries Engine & Machinery Division  and its lifecycle service company HD Hyundai Marine Solution. The agreement, continuing a collaboration that started in 2024, will ensure that owners of engines built by HHI-EMD and vessels or power plants serviced by HMS can benefit from Accelleron’s turbocharger service expertise, spare parts, lifecycle upgrades and efficiency solutions.

As part of the cooperation, Accelleron will assure delivery of spare parts and expert service for all its turbochargers installed on HIMSEN four-stroke engines designed and two-stroke engines built under license by HHI-EMD. Vessels serviced by HMS will also have access to eco-friendly upgrades including Engine Part-Load Optimization (EPLO), which can significantly improve engine efficiency and emissions on vessels operating at lower engine loads to comply with design efficiency and carbon intensity requirements.

By providing a long-term maintenance offering, Accelleron supports HMS in its role as a one-stop service company providing customers with a lifetime service covering engines and turbochargers. The two companies are also engaged in a digital cooperation, sharing data that enables both Accelleron and HD Hyundai to support customers in increasing engine efficiency and reducing operational costs and emissions.

HHI-EMD has a 35% share of the marine diesel and multi-fuel engine market. More than 15,000 HiMSEN four-stroke engines installed on vessels to date. The company also has a commanding share of the two-stroke engine market, building engines under license from leading engine designers for installation on ships primarily built at HD Hyundai shipyards. HMS offers lifecycle services to all vessels built by HD Hyundai, which is the world’s largest shipbuilder.

HD HMS AM Sales Managing Director, Jang-ho Kim said: “HD HMS is confident that its partnership with Accelleron will play a critical role in achieving the maritime industry’s decarbonization goals. This collaboration will enable us to equip our customers with even more efficient and sustainable ship solutions.”

Accelleron Service Division President Roland Schwarz said: “The long-lasting cooperation between HD Hyundai and Accelleron is built on trust and close collaboration, developed throughout the years to the benefit of our joint customers. The renewal of this agreement is a strong commitment to jointly develop our service offerings further, supporting the decarbonization of the maritime industry by combining engine and turbocharger competence.”
