SILENT MAN PROPULSION FOR GREENLAND RESEARCH VESSEL

Monday, September 16, 2019 

Astilleros Balenciaga in Spain has ordered a complete MAN propulsion package including MAN main and auxiliary engines, 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 61m ice-class trawler is designed by Skipsteknisk of Norway. It will come 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.

Lex Nijsen, Head of Four-Stroke Marine Sales – MAN Energy Solutions, said: “This marks the first time that we have sold an MAN 175D unit to a research vessel, yet another market niche that it capably fills and testament to how versatile a performer this engine is. That it forms part of a complete propulsion package with our 27/38 engine and other MAN equipment is most welcome, and sits well with our intention to increasingly become a supplier of complete propulsion solutions.”

The MAN propulsion package comprises:

  • MAN 8L27/38 Tier III with SCR system
  • five-bladed Alpha propeller
  • Alphatronic 3000 Remote Control system
  • 12V175D auxiliary GenSet Tier III with SCR system
  • D2862 auxilliary GenSet Tier III withSCR system
  • HyProp ECO system.

MAN Energy Solutions reports that 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 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.

The DNV-GL SILENT class is the first set of rules for underwater noise emission from vessels. It provides owners of acoustically-sensitive vessels with concise, realistic criteria regarding underwater noise-emissions. Compliant ships are given the SILENT notation with an additional letter denoting a particular segment; in this case ‘F’ is reserved for vessels engaged in fishing.

HyProp ECO is a system solution that combines a diesel engine with a frequency-converter-driven shaft-alternator/motor and features multiple operational modes including diesel-electric propulsion for low-acoustic research activitites. The system combines the advantages of a bi-directional operating frequency converter for the shaft machine with a high-efficiency CP propeller plant. HyProp ECO is open for shore connection and the integration of energy-storage devices/batteries.
