Completed in March of this year by the Oshima Shipbuilding Co., Ltd., Japan, the double hull bulk coal carrier MV Initial Salute is the first ship in service fitted with selective catalytic reduction of nitrogen oxides removal equipment. The 88,100 dwt ship with an LOA of 770 ft (235 m), is powered by a single slow speed, two stroke, MHI 6UEC60LSII rated at 11,000 kW at 105 rpm. Low-temperature exhaust gases below 570 degF (300 degC) produced by a slow speed two stroke engine were feared to cause contamination the catalysts. Improvements made to the equipment reduced the catalyst poisoning to a minimum level by suppressing the sulfur in the fuel oil to approximately 0.1 percent. The on board tests produced results that meet Tier III NOx emission controls stipulated by IMO. The results were so successful that it has been decided to extend the tests and collect more data over a longer period during normal operational service. [More]

Solar assisted power 2

The two year experiment on the solar-power assisted MS Auriga Leader Car & Truck Carrier of 60,213 GT., jointly developed by NYK and Nippon Oil Corporation has now elapsed and the findings have been released. Despite early optimistic results, the conclusion is disappointing. The tests have shown that providing a stable power supply from the photovoltaic panels is difficult because even a slight change in the weather has a significant influence on the amount of power generated. NYK has not however lost hope and is persevering together with Kawasaki Heavy Industries (KHI), the Monohakobi Technology Institute (MTI) and Nippon Kaiji Kyokai (Class NK). They are initiating further tests starting June 2011, to verify the effects of a new jointly developed hybrid power supply system to control the fluctuating output of the solar panels and diesel generator to deliver a stabilized the supply to the vessel’s electrical power system.

Projects running with NYK Line ships under the Japanese Ministry of Land, Infrastructure, Transport and Tourism are investigating technological developments to curtail CO2 emissions from marine vessels. In the main project, two NYK ships, are equipped with an air blower to supply air to the vessel's bottom to reduce frictional resistance. Mitsubishi Heavy Industries supplied the engines and is also participating in the experiment. It was decided that, a module carrier, would be best type of vessel for this experiment. she has a wide, shallow-draft hull minimizing the energy required by the electrically blower supplying air to the vessel's bottom and should better retain the supplied air under the vessel's bottom.
