An unusual kind of ship is taking shape in the STX Finland shipyard in Turku, Finland. The Aura ll, due for delivery in spring 2012 for multipurpose operations in the Baltic Sea for Finnish owners Gaiamare (a subsidiary of the Meriaura Group) is designed to carry bulky lifts of Finland's lumber, containers, or even wind-farm modules on a spacious deck; while if occasion demands, even to operate as an oil-spill response vessel. That’s not all though: down below are three Wärtsilä 6L20 main generating sets that will power diesel-electric propulsion by means of either liquid bio-fuel (LBF) or MDO making this unique 4,350 dwt ship truly adaptable both above and below decks.

Automatic Engine Tuning

Automatic optimization of marine diesel engine performance using loop control of the cylinder pressure process has been under development for a number of years at both MAN Diesel & Turbo and Wärtsilä. Targeting the slow speed two stroke engines, the key to successful implementation of automatic loop control is reliable sensors able to accurately measure cylinder pressure, providing key data to evaluate the fuel efficiency and engine conditions. Without automatic loop control, ship engines are tuned manually to operate within safe limits while leaving a safety margin for variations in fuel properties and operating conditions. Engines are poorly balanced between cylinders and are often outside recommended deviation limits resulting in increased fuel consumption and higher CO2 emissions. The benefit of auto tuning is that the cylinder pressures are balance and at the highest acceptable pressure offering reduced fuel consumption and CO2 emissions. MAN Diesel & Turbo, ABB, and A.P.Moller have together been running loop control projects since autumn 2007. [More]
