Greenland Research Vessel Picks MAN Hybrid Propulsion
The Astilleros Balenciaga S.A. shipyard in Spain ordered a complete MAN propulsion package – including MAN 27/38 and 175D engines, a five-blade MAN Alpha propeller and both remote-control and MAN HyProp systems – in connection with the construction of a research vessel for the Greenland Institute of Natural Resources.
The 61-m, ice-class trawler is designed by Norwegian company, Skipsteknisk. Delivery of the propulsion package is scheduled for Q1, 2020 with the vessel expected to enter service from spring 2021. MAN Energy Solutions further reports that a large number of fishing vessels featuring a Skipsteknisk design are currently under construction, of which 18 feature MAN propulsion packages.
The MAN propulsion package comprises:
• 1 × MAN 8L27/38 Tier III with an MAN SCR (Selective Catalytic Reduction) system
• 1 × five-bladed Alpha propeller
• 1 × Alphatronic 3000 Remote Control system
• 1 × MAN 12V175D auxiliary GenSet Tier III with an MAN SCR (Selective Catalytic Reduction) system
• 1 × MAN D2862 auxilliary GenSet Tier III with an MAN SCR system
• 1 × HyProp ECO system.
MAN Energy Solutions reports that the vessel’s propulsion package has been assembled with a special focus on minimizing 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
SILENT F notation. Similarly, the fully-integated 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.
SILENT F designation
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 ecofootprint. 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.
