GE Transportation wins first order for new marine diesel engine; 50% reduction in emissions

GE Transportation announced the first sale of its new 12V250 Marine Diesel Engine that is designed to meet EPA Tier 4i and IMO Tier III Emissions standards. GE’s technology eliminates the need for a urea-based after-treatment emissions reduction system, providing more valuable cargo space, and reduces emissions by 50%.

In addition, the 12V250 engine offers increased power of 3,150 kW (4,224 hp) at 900 rpm and 3,500 kW (4,694 hp) at 1000 rpm while maintaining low life-cycle cost, reliability and fuel efficiency.

Oceaneering, a global oilfield provider of engineered services and products, will have five new GE Transportation 12V250 Marine Diesel engines as part of the gensets to power its new subsea support vessel.

GE’s distributor Cummins Mid-South, LLC, will integrate the GE engines into the gensets and deliver them to BAE Systems, a leading provider of ship repair, maintenance, modernization, conversion, overhaul and ship construction, that is building the vessel for Oceaneering. The vessel, model MT6022, is designed for Oceaneering by Marin Teknikk.

GE Transportation’s marine engine technology eliminates the need for a Selective Catalytic Reduction system (SCR) exhaust gas after-treatment and storing or using urea aboard a vessel, thereby preserving precious cargo and tank space.

SCR requires the use of a diesel exhaust fluid, typically urea, to reduce NOx in an after-treatment of exhaust gas. GE’s non-SCR solution is based on the technological advancements of the L250 and V250 engines and requires no supplemental equipment or fluids.

GE Transportation unveiled the 12-cylinder V250 Marine Diesel engine at the International Workboat Show in New Orleans in October.

Maybe NOx reduction without SCR will work out better for GE than it did for Navistar.

Any idea if GE is also using Massive EGR? One problem with MEGR for Navistar was heat rejection, but that might be easier on a boat. Navistar never did meet EPA NOx limits for on-road applications though. Is Tier 4 looser?
