MAN Diesel & Turbo together with Germanischer Lloyd have published a study analyzing the problem of the best way for container ships to meet the present and future exhaust emission regulations. The four technologies investigated in the study are: exhaust gas cleaning by scrubber, scrubber plus Waste Heat Recovery (WHR), LNG as a fuel and LNG with WHR. In the study, circumstances were considered for five sizes of container ship. The smallest is a feeder of 2,500 TEU going up to the largest of 18,000 TEU. For each ship size the speed, engine power, round trip distance and percentage of distance spent in Emission Control Areas is estimated proportionally. The study concludes that LNG offers lower emissions and given the right circumstances, less fuel cost. [More]

Yesterday in London, DNV announce the new Quantum 9000 concept container ship with twin island layout. Considerably larger than the Quantum of 6,200 TEU announced last year, the new 9000 model has a design speed of 22 kn and target capacity of 9,000 TEU yet will be able to use the post 2014 Panama Canal opening up routes from East Asia to the west and east coast ports in USA. The new ship is powered by a single slow speed dual fuel MAN B&W 9S80ME-C9.2-GI rated at 40 MW at 78 rpm. An Exhaust Gas Recirculation (EGR) system on the engine reduces NOx emissions substantially and the addition of a Waste Heat Recovery (WHR) system improves overall efficiency. The payback time for the increased cost of this ship with all its features is estimated to be five to eight years depending on the cost of fuel. [More]
