MAN hybrid propulsion package is made of MAN 27/38 and 175D engines, a 5-bladed MAN Alpha propeller and both remote-control and MAN HyProp systems. Such a package was chosen by the Astilleros Balenciaga shipyard in Spain for the construction of a research vessel addressed to the Greenland Institute of Natural Resources.

The 61-metre, ice-class trawler, designed by Norwegian company named Skipsteknisk, will be equipped with modern research and laboratory facilities, as well as accommodation for 32 people. Delivery of the propulsion package is scheduled for Q1, 2020 with the vessel expected to enter service from spring 2021. According to MAN Energy Solutions, 18 more projects of vessels featuring a Skipsteknisk design will feature MAN propulsion packages.


The MAN hybrid propulsion package: a closer look

The MAN propulsion package includes, in details: one MAN 8L27/38 Tier III engine with an MAN SCR (Selective Catalytic Reduction) system, one five-bladed Alpha propeller, one Alphatronic 3000 Remote Control system, one MAN 12V175D auxiliary GenSet Tier III with an MAN SCR (Selective Catalytic Reduction) system, one MAN D2862 auxilliary GenSet Tier III with an MAN SCR system and, finally, one HyProp ECO system.

The vessel’s propulsion package has been assembled with a special focus on minimising noise. As such, the research vessel will be driven by a diesel-mechanical set-up with the 27/38 acting as main propulsion and the MAN 175D and D2862 engines as auxilliary gensets. The 175D and D2862 will receive double-resilient mounting to comply with the vessel’s

Reduced noise emissions

The fully-integrated MAN HyProp ECO frequency drive for DE operation system will control the rotation of the five-bladed Alpha propeller. Notably, both auxiliary engines are double-resilient seated.


The DNV-GL’s SILENT class is the first set of rules for underwater noise emission from vessels ever published. It provides owners of acoustically-sensitive vessels with concise, realistic criteria regarding underwater noise-emissions. It also gives environmentally-conscious owners an opportunity to demonstrate a low eco- footprint. Compliant ships are given the SILENT notation with an additional letter denoting a particular segment. In the case of the new research vessel, ‘F’ is reserved for vessels engaged in fishing.
