L250 & V250


GE L250 and V250 Series marine diesel engines.

No after-treatment. No kidding.

A world leader in the manufacture of diesel engines

For more than 40 years, GE Marine has built reliable, long-lasting, fuel-efficient mid-speed diesel engines. The engines are found in some of the most challenging industrial environments in the world, including tugboats in Turkey, fishing vessels in Peru and offshore oil and gas ferries and support vessels in Norway. In total, there are more than 15,000.

today's environment

The shipping industry is facing an ever-increasing demand for efficiency, reliability and emissions compliance. 2015 marked the transition from building new vessels to meeting US Environmental Protection Agency (EPA) Tier 4 emission standards. As of January 1, 2016, the IMO Tier III emission standard will take effect in NOx Emission Control Areas (NECA).

designed to exceed

The GE Marine L250 and V250 Series diesel engine meets stringent EPA Tier 4 and IMO Tier III emission standards without the use of selective catalytic reduction (SCR) equipment and urea-based aftertreatment. It also integrates an updated control system, high-pressure common rail fuel injection, two-stage turbocharging and advanced exhaust gas recirculation (EGR) to meet EPA Tier 4 and IMO Tier III emissions.

No aftercare, no kidding

Loading, injecting, and cleaning SCR systems that use urea is time-consuming and expensive. Ships with SCR systems installed should carry 6 to 8 percent more urea tank capacity. The "non-SCR/non-urea" engine-based emission design leaves you with more space for cargo and accommodation, while reducing the time spent on hardware maintenance, saving you money over the life of your vessel.

If you're looking to re-power your existing fleet, the EPA Tier 4 / IMO Tier III L250 and V250 Series diesel engine helps make upgrading your vessels easier. Adding SCR reactors, urea tanks, and dosing equipment to refill a vessel that was not designed to have an SCR system installed is cumbersome. Seamlessly upgrade your fleet, meet emission standards and get back to business faster with the help of our non-urea-based engine.

Size matters

The EPA Tier 4 / IMO Tier III L250 and V250 Series diesel engine is a compact solution for customers. While V250 engines have only grown by about 5%, the L250's design remains virtually the same across EPA Tier 3 / IMO Tier II models. In addition, the engines require no after-treatment equipment, saving customers up to 75% of the total floor space.


Less equipment means less time spent maintaining hardware and servicing technology when there is a problem. When compared to maintaining an SCR system and its related equipment - dosing system, monitoring systems, urea injection and urea tanks - the maintenance time and cost for our EGR based emission solution is minimal and depending on the duty cycle, the time between overhaul is still is an industry leading 40,000 hours.


With an SCR-equipped vessel, owners have a higher operating expense, which involves injecting urea and replacing catalytic reactors.

The maritime industry

With the L250 and V250 series diesel engine, GE Marine offers industry-leading engine technology for emissions compliance for the offshore oil and gas industry. Powering Platform Supply Vessels (PSVs), Offshore Support Vessels (OSVs), Offshore Construction Vessels (OCVs) and Inspection Maintenance and Repair Vessels (IMR) allow customers to see that daily operations are completed cleanly and efficient.


The L250 and V250 series diesel engine supplies global marine markets. Due to NOx taxation, other countries already drive cleaner engines. Many offshore oil and gas support vessels built in Norway today are equipped with SCR systems or are operating cleaner than IMO Emissions Tier II. With our technology, essential emissions are reduced by over 70% and enable in-engine compliance with EPA Tier 4 and IMO Tier III emission standards, making it the environmental choice for global customers.
