However it is clear that no matter which techni- cal solution is chosen, ship operation in the SECA’s will be signifi cantly more expensive. The Norwegian cruise and transport shipping company Color Line together with Wärtsilä recently introduced its fl eet retrofi t program with scrubbers to reduce the sulfur emissions. As the Color Line’s vessels operates solely on the Baltic Sea, they focused on three alternatives before they ordered scrubbers from Wärtsilä: • Conversion of the engine operation from heavy fuel to gas oil, which may be the simpliest but, because of the signifi - cantly higher fuel price, is an expensive solution. • Conversion of the engine operation from heavy fuel to natural gas: This is an available technical solution and gas sup- ply in Norway is plentiful, but it is ahigh investment costs to convert the engines and the infrastructure on board. • Continue engine operation with in- Desulfurization Left The fi rst ferry to be retrofi tted is the Color Line Super Speed 2, which will be carried out in April this year.
