‘Jewel in the crown’ is how Wärtsilä Corporation CEO Björn Rosengren described his company’s Wärtsilä 32 medium speed marine diesel engine in the course of a recent wide-ranging interview for Maritime Reporter. He made this remark in the context that Wärtsilä is currently building up a new joint-venture factory in Nantong for assembly of the Wärtsilä 32 and Wärtsilä 26 engines for the Chinese market.  That he should accord pride of place to the 320-mm cylinder bore four-stroke engine amongst Wärtsilä’s treasury of propulsion power assets is not surprising, bearing in mind the vital part this engine has played in Wärtsilä's international success story, as will be seen.

First conversion to LNG completed

The product tanker MV Bit Viking has completed the first ever conversion worldwide, of a vessel from HFO to LNG and is now in service operating along the Norwegian coastline . The very low emissions now attainable will qualify for lower Norwegian NOx emission taxes. The Bit Viking has a very high safety specification, delivered in 2007, the double hulled product tanker of 24,783 dwt has an LOA of 580 ft (177 m) and a beam of 82 ft (26.3 m). The conversion required a major rebuild of the engines from Wärtsilä 6L46B to 6L50DF engines with output of 7,460 hp (5,700 kW). Although having the same stroke as the old engine, required increasing the cylinder bores from 460 mm to 500 mm and replacing most of the engine parts. Safety analysis and approval was undertaken by Germanischer Lloyd (GL) classification society. [More]

This month, Wärtsilä inaugurated its new spare parts Central Distribution Centre centre in Kampen, the Netherlands,. The Center represents an investment of approximately $96 million (EUR 70 million) and will employ around 140 person. Part of Wärtsilä Global Logistics Services, it integrates eight previously localized spare parts warehouses into one global supply facility and occupies and area of approximately 400,000 ft2 (37,000 m2). Two smaller Distribution Centers in Singapore and Ft Lauderdale, USA remain to cater for small, fast moving parts. [More]

Eco-friendly Baltic Sea Vessel to Burn LBF in Wärtsilä Diesel Engines

An unusual kind of ship is taking shape in the STX Finland shipyard in Turku, Finland. The Aura ll, due for delivery in spring 2012 for multipurpose operations in the Baltic Sea for Finnish owners Gaiamare (a subsidiary of the Meriaura Group) is designed to carry bulky lifts of Finland's lumber, containers, or even wind-farm modules on a spacious deck; while if occasion demands, even to operate as an oil-spill response vessel. That’s not all though: down below are three Wärtsilä 6L20 main generating sets that will power diesel-electric propulsion by means of either liquid bio-fuel (LBF) or MDO making this unique 4,350 dwt ship truly adaptable both above and below decks.

'Vale Brasil' Juggernaut Iron-ore Ship En-route to China Powered by Wärtsilä

Vale Brasil, the world’s largest ore-carrier, this week en route from the NE coast of Brazil on her maiden voyage to Darien, China, is loaded with 391,000 tons of iron-ore. A juggernaut seen by market analyst Erik Nikolai Stavseth, of Arctic Securities ASA in Oslo, as one of a breed of ‘sea monsters’ (more of the same are on order by Brazilian mining conglomerate Vale) that will change the way iron-ore flows to satisfy China’s enormous appetite for the commodity. Why build such gigantic iron-ore carriers, bearing in mind the design challenges? Simply in order to make Brazilian iron-ore competitive in price with the Australian delivery to the Chinese market, despite the commodity having to travel almost double the ocean distance; Vale Brasil offers lower freight costs gained through economy of scale.The good news is that this ship will be flexing green power muscles with a carbon footprint of 34% less per tonne of cargo carried than traditional Capesize vessels &...

Wärtsilä announce the addition of two new 62 and 72 bore engine series to their RT-flex two stroke, low speed programme. The new engines offer significant benefits to both shipowners and operators by way of high propulsion efficiency, reliability, and optimised total cost of ownership. The two new engine series employ well-proven Wärtsilä low-speed technology, together with electronically-controlled fuel supply and control. Wärtsilä's licensee partners in Asia are closely involved in the manufacturing process and all Wärtsilä licensees will have the right to build the new engines. Availability of the 62 is Sept 2013 and 2014 for the 72. [More]

Last month the keel laying ceremony for the Alaska Region Research Vessel (ARRV) R/V Sikuliaq, took place at the Marinette Marine Corporation (MMC) shipyard in Marinette, Wisconsin. The LOA is 261.5ft, maximum beam 52.0ft, draft is 19.5ft and loaded displacement is 4,065 long tons. She has a maximum speed of 14 kn in calm water. Several challenges had to be overcome in the design of the propulsion system for this research ship. Two Siemens main propulsion motors drive each pod. Electric power on board is supplied by two MTU 16V4000 plus two MTU 12V4000 gensets. Completion date for the vessel is April 2013. [More]

The Application of LNG as a Fuel for Medium and High Speed Ferries

Austal Ltd, has just completed an 18 month study on the development of several new types of fast ferry. Their study concluded that the most promising solutions for future regulations are multi-hulled HSC code compliant ferries running at a significantly slower speeds than present fast ferries. Austal gives three examples of new designs using LNG as the main fuel. The largest example is a 127 m trimaran ferry powered by twin dual fuel GE LM2500 gas turbines. A smaller 102 m trimaran ferry uses three 4 MW Wärtsilä 9L34DF dual fuel, medium speed engines. The smallest design example is a 72 m catamaran ferry using a dual fuel diesel/LNG electric propulsion system of four 2.3 MW Bergen dual fuel engines. [More]

This week the first Advanced Induction Motor (AIM) was installed in the Royal Navy's Queen Elizabeth Class (QEC) aircraft carrier construction block at shipbuilder BAE System, Glasgow.
The ship has an Integrated Full Electric Propulsion (IFEP) system and uses four 20MW (27,000 hp) electric motors of a similar type to that used in the UK’s Type 45 destroyers. For aspects of stability the diesel gensets are located low in the ship and were delivered at an earlier stage of the construction. [More]

Water Carrier for 2030

During last year’s SMM exhibition in Hamburg Wärtsilä made a presentation called Shipping Scenarios 2030 in which three different future scenarios concerning the shipping industry were shown. One scenario could be that by 2030 freshwater becomes such a valuable commodity that it is transported across the seas in large tankers to places where it is in short supply. Wärtsilä propose a futuristic design of a 150 000 dwt water carrier with a single hull construction and a streamlined deckhouse positioned amidships. Four Flettner Rotors would harness free wind energy; main propulsion would be by a whale-tail propulsion system. Power to drive the rotor and fish tail would be by multi-fuel engines and hull resistance would be reduced using an air lubrication system. [More]
