T he 218-metre long cruise ferry, ordered by Viking Line, is scheduled for delivery at the beginning of 2013. Viking Grace will serve the Turku – Åland Islands (Finland) – Stockholm (Sweden) route. The keel-laying of the ship took place in March 2012 and at the end of June, the Project Manager Vesa Airaksinen confirms the project is proceeding according to the plans at the shipyard. “We are putting the final blocks together at the end of June and will float out the vessel in early August,” Airaksinen provides an update. He acknowledges that the project is an unusual one because of LNG fuel, but the actual routines of ship-building remain quite unchanged: “We are doing some new things with this vessel for the first time, but for the most part, it’s business as usual.” For the Turku shipyard, the project brings approximately 2 600 man-years of labour in total. CENTRE OF ATTENTION Airaksinen is aware of the waves the newbuild is already causing around the industry: the ship has attracted a lot of interest both nationally and internationally due to its environmental innovations. The buzz is assessed to be a positive thing for STX Finland and also the Finnish shipbuilding industry as a whole – it shows the world that the cruise business can, indeed, go green. In February it was announced that AGA Gas AB will supply the liquefied natural gas for Viking Grace. At the time, Mikael Backman, President and CEO of Viking Line, remarked that Viking Line’s and AGA’s investment in LNG represents “major environmental advantages” compared to traditional maritime fuel. Viking Grace will also be Viking Line’s largest passenger ferry to date. But how does LNG work in practice? – The liquefied gas will be stored in specially built tanks at the rear of the vessel and will have a temperature of about – 160 degrees Celsius when it is bunkered and stored on board. It is noteworthy that LNG contains neither sulphur nor heavy metals. By using seatec 2/2012 17
