Marine sector stakeholders discuss merits of natural gas and diesel use

Niels Tholen - 24 November 2014

The topic of natural gas versus marine gas oil (MGO) in marine applications was widely discussed at the 7th Integer Emissions Summit USA 2014 held in Chicago, IL. Niels Mortensen, Director of Regulatory Affairs at Maersk discussed the implications of the IMO regulations becoming stricter for SOx and NOx. These stringent Phase III standards will see the implementation of cleaner fuel and abandonment of heavy fuel oil (HFO). Chuck Griffiths, Sales Manager, Offshore, Marine Medium Speed at MAN, highlighted the option for Selective Catalytic Reduction (SCR) and dual-fuel engines while global natural gas quality and storage is still being brought up to speed. Tanaka Hironaka, Deputy General Manager, Marine SCR department at Hitachi Zosen reported his firm's belief in MGO and SCR technology for 2-stroke marine engines, while GE Marine's Rob van Solingen, Product Manager, Marine, highlighted GE's EPA Tier 4 / IMO Tier III complying 2-stroke EGR engine able to achieve the latter emission standards without the use of SCR.
