Wärtsilä has received its first two orders, a total of seven engines, for their X62 2-stroke low speed engine. The X62 is a midsize engine tailor made for Panamax Bulk Carriers, Aframax or Long Range 2 (LR2) Tankers and Container feeders. It is part of the new engine generation X 2-stroke engine family which was recently introduced to the market. According to the contracts, the main engines will be supplied to power:  - Four new LR2 tankers being built for Kyklades Maritime Corporation, a Greek ship owner, at Hyundai Heavy Industries Co., Ltd (HHI) in South Korea.  - Three bulk carriers for Suisse-Atlantique, the Switzerland based global fleet operator, to be built at Hyundai Mipo Dockyard's (HMD) facilities in Vietnam.   The vessels will be of the new Ecodesign developed by the yards to reduce fuel consumption and emissions substantially compared to previous tonnage. Both orders were signed during the second quarter of 2013 and the engines will be manufactured... [More]

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]

At last month’s International Tug & Salvage Conference, Corvus Energy Ltd presented a paper on a new battery type – Nickel Manganese Cobalt , NMC for short, that is particularly good for propulsion applications. It uses safe chemistry that is stable and reliable. is sealed and is compact. It can deliver a high power until fully discharge, doesn't’t deteriorate if left uncharged and hardly looses its charge over time. What does this mean for the marine industry? One example was the announcement at the Conference of an all electric tug boat, so far it is only for training purposes but heralds the beginning of a new era of electric driven vessels whether pure electric drive or hybrid diesel electric.
