MAN Energy Solutions has announced that its after-sales division, MAN PrimeServ, Frederikshavn is set to perform a radical and extensive optimisation of the propulsion drivetrain of a 2007/2008 gas tanker during its forthcoming dry docking. The solution for the Solvang ASA-owned vessel will enable it to meet impending EEXI regulations via main-engine power limitation and brings the vessel’s propulsive efficiency on par with modern buildings via, among other initiatives, clever optimisation of the existing CP propeller and aft-ship system.The 2007/2008 gas tanker project will entail the introduction of optimised propeller blades, a propeller-hub fairing cone and EcoBulb rudder-bulb integration developed in close cooperation with Becker Marine Systems, Solvang ASA and MAN Energy Solutions’ hydrodynamic experts. Besides MAN Energy Solution’s scope of supply, the vessel will also be permanently power de-rated, EEXI power-limited, and equipped with a Mewis duct installation. The work will position Solvang ASA a first mover within advanced, holistic vessel optimisation.Solvang ASA dates back to 1936 and has developed into one of the world’s leading transporters of LPG and petrochemical gases.
