Everllence has marked the first TCT turbocharger to be produced under license in Japan, a TCT40 unit built by the Mitsui E&S Tamano factory.
Everllence launched the TCT turbocharger series in 2019, starting with the TCT40, and subsequently followed by the TCT30, TCT50 and TCT60. Ultimately, the series will comprise six frame-sizes including TCT70 and TCT80 units. The radial compressor and axial turbine are key components of the series. Both have been developed with new design features, backed by the latest simulation technologies, resulting in a compact and lightweight turbocharger design, covering a variety of fuel types. Thanks to the charging efficiencies, wide compressor maps and ample matching options, TCT turbochargers can easily be matched to engines, covering a range of engine-tuning options as well as requirements of today’s exhaust-gas after-treatment systems for IMO Tier III operations.
In general, TCT turbochargers are said to offer the following features:
For two-stroke engines, TCT-series turbochargers are suitable for power ratings from 5.5 MW up to 24 MW per turbocharger. Typical applications include prime movers for container vessels, large bulk carriers or tankers.
As one of the largest, marine, two-stroke engine builders, Mitsui E&S has been an Everllence turbocharger licensee since 1981. In 2022, it successfully concluded negotiations to build Everllence’s new TCT axial-turbocharger series, replacing the older TCA turbocharger for two-stroke engines. While production in Japan is beginning with the TCT40 model, it intends to progressively add other sizes in the TCT range over time. The turbochargers will be installed on Mitsui-manufactured Everllence two-stroke engines.
Ichiro Tanaka, Director, Mitsui E&S said: “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. It is a great pleasure to commence production of the latest turbocharger, the ‘Mitsui-Everllence TCT40’ under this license. We deeply appreciate the strong partnership between the two companies and the dedicated efforts of everyone involved. We look forward to continuing our successful collaboration in the years to come.”
Dr Daniel Struckmeier, MD Everllence Japan, added: “This is a significant 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. 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. We are very happy with developments and are confident that it will further enhance the appeal of Mitsui E&S within the two-stroke engine segment while highlighting the strength of the TCT series.”
