MITSUI E&S, Everllence Produce First TCT Turbocharger in Japan

At a ceremony in Tamano City, Japan, MITSUI E&S and Everllence unveiled the first TCT turbocharger to be produced under license domestically—the TCT40 axial turbocharger. In 2022, MITSUI agreed to build Everllence’s TCT axial-turbocharger series to replace older turbocharger models for two-stroke engines. Japanese production will begin with the TCT40 model, with plans to build additional TCT sizes over time.

“Since entering into a licensing agreement with Everllence in 1981, we have manufactured and sold over 4,000 MITSUI-Everllence turbochargers over the past 40 years,” said Ichiro Tanaka, Director of MITSUI E&S. “It is a great pleasure to commence production of the latest turbocharger, the ‘MITSUI-Everllence TCT40’ under this license. We appreciate the partnership between the two companies and the efforts of everyone involved. We look forward to continuing our collaboration in the years to come.”

The TCT40 features a newly developed radial compressor and axial turbine tested with the latest simulation technologies, establishing a compact and lightweight turbocharger design. It provides significant charging efficiencies, wide compressor maps, and matching options to multiple engines. This variability covers a wide range of engine-tuning options and fuel types and complies with exhaust gas after-treatment systems for IMO Tier III operations.

“This is a milestone that has been coming since our two companies signed the TCT licence agreement, enabling MITSUI E&S to bring our latest turbocharger technologies to the market,” said Dr. Daniel Struckmeier, Managing Director of Everllence Japan. “At the same time, we know that many Japanese customers prefer products that are manufactured domestically. Local production helps build trust, ensures faster delivery, and aligns with customer expectations for domestic sourcing.”

TCT-series turbochargers are suitable for two-stroke engines in the 5.5 – 24 MW range, with typical applications including prime movers for container vessels, large bulk carriers, and tankers. Generally, TCT models offer the following features:

• Long TBOs and high-performance bearings
• Maintenance-friendly service concept and low lifecycle costs
• High specific flow rates for a compact and lightweight design
• Low noise emissions
• High efficiency levels

In 2019, Everllence launched the TCT turbocharger series, starting with the TCT40 and followed by the TCT30, TCT50, and TCT60. The series will ultimately comprise six frames including the TCT70 and TCT80 units.

Ethanol-Fired Engine

Last month, Everllence successfully operated its 90-bore ME-LGIM two-stroke engine on ethanol, at all load points, in Japan. Its successful ethanol-running validation provides Everllence with a fully operational engine to document ethanol capabilities for the ME-LGIM platform.

Over a decade ago, Everllence developed the ME-LGIM platform with the first commercial engine entering service in 2016 within the methanol-carrier segment. The company leveraged this operating experience by upscaling its methanol burning portfolio in 2021, installing the first ME-LGIM outside the methanol-carrier segment.

Ammonia Dual-Fuel Engine

In late August 2025, Höegh Autoliners ordered four Everllence B&W ME-LGIA dual-fuel engines, with ammonia-burning capabilities, for the construction of four Aurora-class pure car/truck carriers (PCTCs) at an Asian shipyard. Each PCTC features a 9,100-CEU capacity and will operate under the Leif Höegh & Co. shipping company. HD Hyundai Heavy Industries Co. will assemble the 7S60ME-LGIA engines in South Korea.
