Dieselman Marine Service operates within an international framework that centers on technical support for marine diesel engines and related maritime activities. The organization’s headquarters are located in Shanghai, where it oversees a network of regional branches that extend its reach across major marine hubs in Asia. Established in 2017, the group developed around a core team with extensive backgrounds in marine engineering and long experience working with large engine manufacturers. The Shanghai office functions as the primary coordination point for worldwide technical service programs, managing teams that provide inspection, troubleshooting, and maintenance support for vessels operating across different trade routes.
In addition to its main base, the company maintains a presence in Busan, where its Korea branch supports ship operators in both Korea and Japan. This office handles technical services and regional sales, enabling it to address the needs of shipyards, vessel owners, and operators engaged in coastal and international shipping. The Singapore branch, located in the Tuas industrial area, focuses on service and sales within Singapore and Southeast Asia. It supports a busy maritime corridor where ship repair, overhauls, and equipment servicing are frequent requirements for commercial vessels, offshore units, and regional cargo fleets.
Some affiliated entities in Singapore are registered under the same group name and are engaged in shipbuilding and ship repair activities, including work on tankers and other ocean‑going vessels. These companies also participate in the manufacture and repair of marine engines and maintain active registrations as local companies. Their activities align closely with the broader group’s emphasis on technical service, repair capability, and support for vessel operators across commercial and offshore sectors.
Throughout its operations, Dieselman Marine Service focuses on ensuring that vessels remain operational through reliable technical intervention, covering tasks such as engine maintenance, mechanical inspection, and workshop‑based repair. This combination of regional offices, technical expertise, and direct engagement with ship operators positions the company as a service‑oriented contributor to the maritime and offshore industries.
