Over capacities in the ship transport sector led, after the crisis of 2008/09 in shipping, to a drop of charter rate 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 follows these needs. HFO (Heavy Fuel Oil) 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(California Air Resolution Prevention)) will need more attention to be paid in the coming future regarding safe engine operation and sensitive equipment especially with the change-over in between different types of fuel. On the other hand the more complex in techniques and paperwork like, TIER I retrofit and more competition for 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 techniques and less experience of crew which may lead to a higher potential risk or give a wide range of challenges for ship operators to deal with. Additionally, coming systems and administration work like: ballast water treatment systems and regulation, piracy prevention, EEDI(Energy Efficiency Design Index) and SEEMP (Ship Energy Efficiency Management Plan)will give more challenges in the very near future for the shipping industry. Furthermore, the coming LNG conversion for Baltic Sea operation before 2015 and, TIER III legislation, will lead to drastic increases of complexity in engine plants and installation of SCR catalysts, exhaust gas re-circulation, water emulsion use and two-stage turbo charging will raise the installation and operation cost and may overwhelm the limited resources of engineers.
