At a semi-digital ceremony in Busan, South Korea in late-December 2021, MAN Energy Solutions signed a licence agreement with Hyundai Heavy Industries (HHI-EMD) for MAN’s new TCT axial-turbocharger series. Due to run for ten years, this is the first turbocharger licence agreement MAN Energy Solutions has ever signed with HHI-EMD, according to the company's release.
Generally acknowledged as the largest, marine two-stroke engine builder in the world, HHI-EMD has been a low-speed licencee of MAN Energy Solutions for decades. MAN Energy Solutions reports that the turbocharger licence agreement was finalised after intense and comprehensive negotiations.
MAN-ES 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 newly developed 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 very compact and lightweight turbocharger design. Thanks to its superior charging efficiencies, wide compressor maps and ample matching options, TCT turbochargers can easily be matched to engines. Their variability covers not only a wide range of engine-tuning options and fuel types, but also all new requirements of today’s exhaust-gas after-treatment systems for IMO Tier III operations.
In general, TCT turbochargers offer the following features:
• long TBOs – high performance bearings
• maintenance-friendly service concept resulting in low life-cycle costs
• highest specific flow rates, resulting in a compact and lightweight design
• lowest noise emissions
• highest efficiency levels.
For two-stroke engines, TCT-series turbochargers are suitable for engines ranging from 5.5 MW up to 24 MW per turbocharger. Typical applications include prime movers for container vessels, large bulk carriers or tankers.
