The 250MDC marine diesel engines meet EPA Tier 4 and IMO III emissions standards with advanced exhaust gas recirculation that does not require urea-based aftertreatment. This advanced technology limits the formation of NOx in cylinder as opposed to removing NOx from the exhaust through an aftertreatment system, while maintaining world class fuel efficiency.

Key benefits: 

• Eliminates the need for an ESCR system and urea storage tanks, preserving valuable cargo and accommodation capacity - up to 40% less space and up to 50% less weight
• No additional logistics and operating expenses for urea replenishment and handling - up to 10% operating cost savings
• Reduces ship-design complexity and shipyard installation time and cost compared to an engine with an SCR aftertreatment solution - up to 50% less installation cost
• Robust and proven design, simple to operate
• World-class fuel efficiency and load response with practically no visible smoke
• High engine enery efficiency with more heat recovery available in jacket water system from EGR
• Narrow footprint allows ease of maintenance and packaging advantage
• 100% power take off (PTO) from either end of the engine
• Low vibration and noise generation

Engineered, manufactured and tested to withstand the harshest requirements, Wabtec Corporation's drilling motors are synonymous with quality and reliability. In use every day, thousands ow Wabtec motors prove time and again their singular ability to meet or exceed customer expectation driving drawworks, mud pumps, cement pumps, rotary tables, top drives and anchor-handling winches on all types of drilling rigs all over the world.

Year after year, we have built thousands of reliable AC and DC motors for demanding applications in numerous industries. 

• Oil & Gas - drill rig drawworks, mud pumps, rotary tables and top drives
• Marine - propulsion, winches, thrusters
• Dredge - cutters, pumps
• Industraial - conveyors, mixers, compressors, pumps, cranes

Wabtec has a global installed base of over 30,000 traction motors powering demanding applications from drilling rigs and locomotives to mining trucks, dredges and marine propulsion.

How important is your rig's continued operation? What is the cost of your operations shutting down for a day? on land or offshore, that's a cost you can't afford. That's why heavy industry turns to Wabtec.
