What is Wartsila’s Biggest Marine Engine

Marine engines serve as the core and essence of all waterborne vessels, whether they be recreational boats or colossal cargo ships. These formidable machines are meticulously engineered to endure the challenging conditions of the open sea, all the while delivering dependable and effective propulsion. The Wartsila RT-flex96C stands as a noteworthy turbocharged, two-stroke reciprocating diesel engine meticulously engineered to propel massive container ships, securing its title as the world’s largest engine. Crafted within Japan’s Diesel United, Ltd.’s Aioi Works, this huge engine boasts dimensions of 27 metres in length (88 ft 7 in), a towering 13.5 metres in height (44 ft 4 in), and a staggering weight exceeding 2,300 tonnes.

This engine deploys advanced fuel injection methods that reduce traditional components such as camshafts, chain gears, fuel pumps, and hydraulic actuators. In 2008, the 14-cylinder variant achieved an astounding power output of 84.42 Megawatts (114,800 brake horsepower [bhp]), showcasing superior performance with reduced fuel consumption and lower emissions.

This exceptional engine propels the MV Emma Maersk, the world’s largest container ship, solidifying its significance in maritime technology.

Maritime Power with Wartsila Marine Diesel Engines

Wartsila marine diesel engines are renowned for their reliability and exceptional power output, all while promoting better fuel economy. With a commitment to being at the forefront of technology and innovation, they provide solutions that not only deliver optimal performance but also help reduce emissions, contributing to a greener maritime industry.

The ground-breaking 14-cylinder Wartsila RT-flex96C engine, the world’s first of its kind, set sail on September 1, 2006, aboard a large, high-speed container vessel. Developed by Wartsila Corporation, this extraordinary engine boasts an impressive output of 80,080 kW (108,920 brake horsepower [bhp]), making it the most powerful engine globally.

The 14-cylinder Wartsila RT-flex96C engine represented a significant leap forward in ship propulsion technology. It not only meets the power demands of the new generation of large container ships but also combines the proven reliability of traditional engine designs with the flexibility of RT-flex common-rail technology. This innovative technology offers unparalleled flexibility in engine operation, resulting in smokeless operation at all speeds, reduced fuel consumption, lower maintenance costs, and enhanced steady operating speeds for improved manoeuvrability.

Traditionally, low-speed marine engines were limited to a maximum of 12 cylinders. Recognising the need for increased power in response to the growing demand for larger container ships, Wartsila introduced 13- and 14-cylinder engines. Extensive attention was given to ensuring the practicality of these increased cylinder counts, as well as upholding the highest standards of safety, reliability, and durability that our customers expect.
