from marine engines, while at the same time offering a cost effective product. Tis is in line with our efforts to enhance sustainable shipping and we see great demand for it in the current market,” says Mr Anders Eklund, director, product engineering in product centre 2-stroke, Wärtsilä Industrial Operations.


Scrubbers Wärtsilä delivers


marine scrubber Finland’s Containerships Ltd Oy has earmarked its vessel Containerships VII to fit the Wärtsilä fresh water scrubber which reduces SOx emissions from ships’ exhaust. Wärtsilä and Containerships signed an agreement last month covering the retrofitting of a fresh water scrubber to the vessel which is alsofitted with a Wärtsilä W7L64 main engine. Wärtsilä’s said that the Containerships VII project was its first commercial marine scrubber project for a main engine. Te scrubber will be delivered in August 2011. Te conversion will enable the vessel to meet future sulphur oxides (SOx) emission requirements in Sulphur Emission Control Areas. “Te Wärtsilä fresh water scrubber technology


will meet both environmental and commercial requirements for our operations. We see it as a clear advantage that Wärtsilä, with its long experience in emissions abatement technology, delivers the scrubber solution,” said Sigurjon Markusson, Containerships’ CEO. Wärtsilä is the first manufacturer to have been


awarded a marine scrubber certificate by the classification societies Det Norske Veritas and Germanischer Lloyd. Te Wärtsilä scrubber works with fresh water in


a closed-loop system in which sulphur oxides are neutralised with caustic soda. A small amount of scrubbing water is extracted to remove contaminants in a treatment unit onboard, thereby fulfilling all the quality and monitoring requirements stipulated by the IMO. In so-called zero discharge mode, the clean effluents are led to a holding tank for scheduled and periodical discharge. Contaminants should be disposed of at reception facilities in port.


Engines


Wärtsilä engines Finnish ferry operator Viking Line has ordered four Wärtsilä 8L50DF dual fuel main engines, the transverse bow and stern tunnel thrusters, and two stainless steel fixed pitch, built-up main propellers with complete


Viking Line orders 10


propeller shaſt lines and environmentally sound shaſt line seal systems for its latest ferry currently under construction at the STX Finland. The propellers for the vessel, which is due for


delivery in 2013, are designed with the lowest possible pressure impulses which should significantly improve vibration control. Viking Line’s ferry will be the largest passenger ferry


operating on liquefied natural gas (LNG), making it the most environmentally friendly and energy efficient large passenger vessel in the industry to date. The vessel will operate on the route between


Turku and Stockholm, Sweden in the Baltic Sea. Te agreement includes an option for the supply of equipment to a similar sister ship. STX Finland is part of the international STX Europe Group. Viking Line’s ferry will be capable of carrying


cars, trucks and road trailers on short international voyages. It is also designed to carry 2800 passengers and 200 crew members. Te machinery, equipment and outfitting, as well as the structural work, will be under the special survey of the Lloyd’s Register classification society. Meanwhile, TTS, which supplies ro-ro equipment


such as ramps, has been contracted by the Turku yard to supply a stern ramp and door, bow doors, a folding frame bow ramp, an internal ramp/cover, a hoistable car deck with ramps, cargo and provision liſts with covers and side shell doors, all with associated hydraulic and electric systems and with a total weight of more than 400tonnes. Installation of this equipment is due to take place during 2012.


Coatings Raw materials push


paint prices up Steep rises in the price of raw materials during 2010, by as much as 50% in some cases, has forced Jotun into price increases for some of its products. “Troughout 2010 the market price of major raw


materials used in coatings, such as epoxies, titanium dioxide, acrylics and metal-based materials has increased by as much as 50%,” said the company. Jotun said that unexpectedly high global demand


with the decrease in capacity following the 2007 financial crisis “has caused an imbalance in the raw materials market for coatings, which has resulted in shortages of many raw materials and consequently caused prices to spiral”. The situation is not expected to improve in 2011


as crude oil prices soar to their highest levels since 2008 putting upward pressure on petrochemical- based raw materials and metal prices reaching new heights.
