MAN Energy Solutions will deliver the engines, shafts and propellers for the AOPS’ integrated diesel-electric propulsion systems, as well as complete integrated logistics services (ILS) documentation.
Each vessel will feature 4 × MAN 6L32/44CR engines, with each engine delivering 3,600 KW and utilizing common-rail (CR) electronic injection, high-efficiency turbochargers, electronic hardware and variable valve timing.
The company will also provide a selective catalytic reduction system with each engine. In combination with the SCR system, the common-rail injection system is expected to optimized each engine’s fuel consumption and emissions, resulting in IMO Tier III compliancy without sacrificing engine efficiency. This ultimately could reduce each ship’s carbon footprint to a minimum, a crucial factor when considering the fragile Arctic environment for which the ships are destined.
Finally, MAN Energy Solutions will deliver 2 × MAN Alpha-branded five-bladed, bolted propellers that meet PC5 rules and which can even be exchanged underwater. These cater for higher cavitation inception speeds, possible shock impacts, and mission-critical conditions requiring additional redundancy, silent operation with minimal hydro-acoustic signatures, and suppressed underwater-radiated noise, the company highlighted.
