“ Most of our sustainability work involves different solutions that passengers don ’ t notice , like the vessel ’ s technical solutions , which have seen rapid advances . Ten years ago , Grace was the world ’ s most environmentally-friendly passenger ship and now Glory , which is bigger , will use about ten per cent less fuel ,” Lindberg says .
Viking Glory is one of the first vessels in the world to use Wärtsilä ’ s 31DF dualfuel engines and run on liquefied natural gas ( LNG ). They enable optimization of fuel use but produce no sulphur emissions at all . Furthermore , they produce fewer carbon dioxide emissions than do diesel engines .
Project Manager Kari Granberg , who is in charge of the new construction at Viking Line , says that the vessel ’ s six 31DF engines feature the lowest fuel consumption , but at the same time , have the highest cylinder output in their segment ( 550 kW / cylinder ).
RECOVERING WASTE COLD
Viking Glory will also , as the first in the world , recover the waste cold from the use of LNG and recycle it for use in cold counters , cold rooms , and other special rooms .
“ Today , recovery of waste heat is already common , but to recycle waste cold for the purposes of refrigeration appliances and cold rooms is an innovative and highly climate-smart solution ,” Granberg says , adding that Viking Line has carried out development work in collaboration with Wärtsilä , Projektia and Deltamarin .
Captain Ulf Lindroos says that when Viking Grace started running on LNG , sulphur and particulate matter emissions were reduced by 85 per cent while greenhouse gas emissions were reduced by 15 per cent compared to oil .
“ Like Grace , Glory will also run on biogas or synthetic fuels produced using renewable energy when these are available in the future ,” says Lindroos .
MAKING MOVES
As Viking Glory kicks off operations , this marks also the first time when a passenger ship of this kind utilises the Azipod propulsion unit manufactured by ABB as a means of saving time and energy in terms of ship manoeuvring : the system facilitates faster turns in the ports and a hull design with
