New and Used Diesel Marine Generators
New and used diesel marine generators provide auxiliary and propulsion power for ships, offshore platforms, floating power stations, and barge-mounted power plants. The MTU Series 4000 marine engine, with over 58,000 units sold worldwide and over 345 million accumulated operating hours since the platform launched in 1996, is one of the most established commercial marine diesel platforms in service. The Series 4000 covers 8, 12, 16, and 20 cylinder V-configurations rated from 1,000 hp to 5,780 hp (up to 4,300 kW), with the 4000 marine genset variants delivering 1,125 to 3,250 kWe per unit.
The platform is certified to all major classification societies (ABS, BV, CCS, CR, DNV, GL, KR, LR, NK, RINA) and complies with IMO Tier II, EU IIIA, and EPA Tier 2 emissions regulations. Common rail injection at 1,800 bar across the operating range, sequential turbocharging, and four valves per cylinder support low fuel consumption and low NOx and particulate emissions across the full speed range. USP&E supplies marine diesel generators across 50 Hz and 60 Hz applications. Click Fast Quote for a response within hours.
Used diesel marine generators and applications
Marine diesel generators serve three principal markets: ship auxiliary and main propulsion power, offshore oil and gas platform supply, and floating or barge-mounted power stations serving coastal grids. Within the merchant fleet and offshore services, MTU Series 4000 engines are commonly used in commercial vessels, workboats, and large yachts. Within naval applications, shock-resistant variants of the Series 4000 platform meet the latest NATO requirements and are used in diesel-electric submarines and surface combatants.
Common Rail Injection and Classification Society Compliance
The MTU Series 4000 platform delivers compliance with current emissions regulations through internal engine technology only, without exhaust aftertreatment. Second-generation common rail fuel injection at constant 1,800 bar across the operating range, MTU’s ADEC electronic management system with triple injection electronics (pilot, main, and after-injection), and dual or quadruple sequential turbocharging combine to deliver low emissions and high efficiency. Each engine is type-approved by the major classification societies for marine service.
