MAN’s Innovative Hybrid Propulsion System for Tanker



MAN Diesel & Turbo SE (MAN) announced that it has an order to provide a complete propulsion package for a 7,500 DWT chemical tanker, which will include its “innovative” and bunker-saving full HyProp ECO hybrid propulsion system with PTO/PTH – noted to be a world first.

HyProp ECO, which combines a diesel engine with a frequency converter driven shaft-alternator/motor and features multiple operational modes, is said to have been jointly developed by Vacon and MAN.

The system is said to offer the benefits of a bi-directional operating frequency converter for the shaft machine with a high-efficiency CP propeller plant, and can enable shore connection and the integration of batteries and energy storage devices.

“For many applications, a hybrid propulsion system is a good choice, especially when flexibility, performance and efficiency are prized.  In a challenging market, we are embracing innovative technology as a means to grow,” said Lex Nijsen, Head of Four-Stroke Marine at MAN.

“HyProp ECO is a flexible and powerful system with low first-costs that offers a real alternative to a purely mechanical propulsion solution, while maintaining its benefits. We are proud that IÇDAŞ chose our high-efficiency technology package for their newbuilding.”

The propulsion package set to be delivered to the newbuild vessel is also said to feature a MAN 6L32/44CR common-rail main engine, an MAN Alpha Kappel propeller, and a MAN Selective Catalytic Reduction (SCR) system that can operate on MGO, MDO and HFO.

The stainless-steel chemical tanker, which is slated for delivery in September 2017, is noted to have been ordered and will be operated by Turkey-based IÇDAŞ Çelik Enerji Tersane Ve Ulaşim Sanayi AŞ.

As Ship & Bunker reported in June, Christian Poensgen, senior vice president engineering at MAN said low bunker prices mean that energy efficiency improvements on marine engines need to be delivered at “twice the value for the same price.”
