MAN Achieves New Milestones for WHR Systems

MAN Diesel & Turbo’s recent market introduction of its new generation of waste heat recovery (WHR) systems is already notching up important milestones.

Concurrent with the successful commissioning of the TCS-PTG22 units in Panama, a further TCS-PTG20 has successfully passed its factory acceptance test in the presence of the DNV GL classification society at MAN Diesel & Turbo’s Augsburg’s premises. The TCS-PTG20 is one of two units bound for German shipowner Reederei Horst Zeppenfeld for use aboard two 4,700 TEU container vessels currently under construction at Samjin Shipbuilding in Weihai, China.

The ships are each powered by an MAN B&W 6S80ME-C9.2 low-speed engine, rated at 27,060 kW. Each TCS-PTG20 unit will supply 920 kW to the board grid.

The order represents the first such instance of a marine application for MAN Diesel & Turbo’s new generation of TCS-PTGs. Along with the two TCS-PTG20s, MAN Diesel & Turbo will also supply four TCA88 turbochargers, two each aboard the container newbuildings.

Through using the TCS-PTG units, Zeppenfeld will not only save fuel but will also reduce the operating costs of their gensets as these can be run on part-load or switched off when the TCS-PTG units are in operation.

MAN Diesel & Turbo sees a growing potential for WHR systems such as the TCS-PTG, which can recover up to 5% of the energy from a main-engine’s exhaust gases and thus improve a vessel’s energy efficiency design index (EEDI).
