Norwegian ferry operator Bastø Fosen has ordered eight IMO Tier 3-compliant marine diesel engines from GE Marine for new and re-powered vessels. Six are eight-cylinder in-line engines for three new ferries, while two are 16-cylinder V engines destined for existing vessels Bastø I and Bastø II, which are scheduled to begin operating early in 2016.
GE's iron can meet the Tier III requirements without selective catalytic reduction (SCR) after-treatment or urea injection. A study commissioned by GE to the Danish naval engineering firm Jensen Maritime found that its new engine technology needed 75% engine-room space and was 75% lighter than other solutions, mainly attributable to the fact it obviates the need for fitting after-treatment equipment and urea storage.
GE Marine was recently granted U.S. EPA Tier 4 certification for its 12-cylinder V250 marine diesel engine. The OEM is working to achieve U.S. EPA Tier 4 and IMO Tier III certification for its entire family of V250 and L250 marine diesel engine models that also utilise non-SCR technology.
