Baudouin Power Solutions for Oil & Gas Operations

Supporting the Transition to Hybrid Power
The versatility of the 12M26.3 platform is also demonstrated in a new generation of diesel-electric hybrid tugboats developed for BOTAŞ, Türkiye’s state-owned oil and gas pipeline corporation.

Built by Sanmar Shipyards, the ElectRA 2500-SX tugboats will operate at the BOTAŞ Marmara Ereğlisi LNG Terminal and Saros FSRU Terminal, supporting demanding terminal operations where availability, manoeuvrability and emissions performance are key considerations.

Unlike a conventional mechanically driven tug, the ElectRA vessels use a diesel-electric architecture in which onboard generator sets provide power to electric propulsion motors. Each vessel is equipped with two Baudouin 12M26.3 SCR marine gensets, each delivering 954 kWe, complemented by a 5,085 kWh battery energy storage system.

This configuration allows the engines to operate closer to their optimal load range across changing operating profiles, while battery storage supports power peaks and helps reduce engine load variations. The SCR-equipped 12M26.3 gensets also comply with IMO Tier III requirements.

For LNG and FSRU terminal operations, the combination provides an important balance: responsive power when required, optimized energy management during lower-load operation, reduced emissions and redundancy for critical vessel operations.

The project also illustrates Baudouin’s ability to contribute not only an engine, but to work within increasingly sophisticated marine power architectures as the offshore and energy sectors move towards more efficient and electrified solutions.

Scaling Up: The 16M33.3
For offshore vessels requiring higher propulsion power, Baudouin’s 16M33.3 provides a 52.3-litre V16 platform delivering up to 1,545 kW (2,100 hp) at 1,800 rpm.

Developed as a genuine marine engine, the 16M33.3 combines compact power with an architecture designed around reliability, lifecycle cost and straightforward maintenance. Its common-rail technology and turbocharging system support controlled fuel consumption and performance across demanding commercial duty cycles.

For offshore support vessels, workboats and other specialized craft, this combination of power density, durability and maintainability provides shipyards and operators with a flexible solution for applications where vessel availability is critical.

High-Power Offshore Propulsion: The 12M55
At the top of Baudouin’s marine propulsion portfolio, the 12M55 addresses applications requiring significantly higher power.

With a 65.6-litre V12 configuration, the engine delivers up to 2,536 kW (3,450 hp) at 1,800 rpm. Its high output makes it particularly relevant for larger offshore support vessels and other demanding commercial marine applications where sustained power and reliability are essential.

The 12M55 has been engineered with lifecycle performance in mind. Its modular construction and accessible maintenance points are designed to simplify servicing, while its high-pressure common-rail injection and turbocharging technologies contribute to efficient operation.

Together, the 12M26.3, 16M33.3 and 12M55 give Baudouin a broad offering for the offshore sector — from compact propulsion engines and diesel-electric power generation to engines exceeding 2.5 MW for larger vessels.

One Power Partner for Demanding Marine Operations
The ADNOC and BOTAŞ projects demonstrate two different approaches to powering vessels serving the oil and gas industry.

On ADNOC’s specialized diving vessels, the 12M26.3 provides direct mechanical propulsion, supported by Baudouin auxiliary gensets. On the BOTAŞ ElectRA tugboats, the same engine platform forms part of a diesel-electric hybrid architecture, generating electrical power alongside battery energy storage.

This versatility is increasingly important as shipyards and operators balance traditional requirements for reliability, durability and lifecycle cost with new objectives around efficiency, emissions and electrification.

With more than a century of marine engineering heritage and an international service network, Baudouin continues to develop power solutions for the evolving requirements of professional marine operators - from proven diesel propulsion to high-power engines and increasingly sophisticated hybrid power architectures.
