论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。 Over capacities in the ship transport sector lead, after the crisis of 2008/09 in shipping, to a drop of charter rates income and especially in the container carriers business to super slow steaming, now updated to 10% maximum continuous rating (MCR).Flexible turbo charger cut out with it’s further fuel saving and operation improvements becomes more and more standard and can optimize the new operation range of big bore main engines. The coming new buildings are planned already for a service speed of 21 down to 14 kn with much smaller main engines in contradiction to the unsolved problems in high risk areas.Adaptation of cylinder lubrication to super slow steaming follow these needs. HFO sulphur content with a max. 3.5% S since 1.1.2012 and new universal cylinder oils take note of changes on the world fuel markets and emission control areas (ECA). On the other hand a few companies are developing wet- or dry-scrubber technologies to use soon, with high sulphur fuels, even higher than 4,5% S back again on board which will also be challenging for the engine environment of the future. The enlarged and changing different emission controlled areas (ECA and CARP) will need more attention to be paid in the coming future regarding safe engine operation and sensitive equipment especially with change-over in between different type of fuels. On the other hand the more complexity in technique and paperwork like, TIER I retrofit and more competition on the well educated human resources lead to faster educated crews with less practical experience being under high psychological pressure. A permanent drop of component quality and cost-down-design pressure in the market interfere with the higher demanding technique and less experience of crew which may lead to a higher potential risk or give a wide range of challenges for the ship operators to deal with. Additionally, coming systems and administration work like: ballast water treatment systems and regulation, piracy prevention, EEDI and SEEMP will give more challenges in very near future for the shipping industry. Furthermore, the coming LNG conversion for Baltic Sea operation before 2015, TIER III legislation, will lead to drastic increases of complexity in engine plants. and installa- tion of SCR catalysts, exhaust gas recirculation, water emulsion use and double stage turbo charging will raise the installation and operation cost and may overwhelm the limited resources of engineers.
