**Note that price is per unit
This new Mitsubishi S12R-T2-MPTK diesel engine is a USP&E asset currently located in Asia, available now and listed under stock number USP011028. Rated at 1.2 MW and manufactured in 2025, this unit is in new condition and purpose-built for unlimited continuous commercial duty and heavy marine operations. Hours are to be confirmed through technical review, consistent with a brand-new unit of this class. The new Mitsubishi S12R-T2-MPTK diesel engine is diesel-fuelled and configured as a marine engine, making it directly suitable for vessel propulsion, onboard power generation, and offshore support applications across demanding operating environments. This asset is available through USP&E. As a new Mitsubishi S12R-T2-MPTK diesel engine, it represents the current production standard from one of Japan's most trusted industrial engine manufacturers, with full Mitsubishi engineering behind its 1.2 MW continuous output rating.
The Mitsubishi S12R series is a 12-cylinder, V-configuration turbocharged diesel engine platform with a long-standing reputation in heavy marine and commercial continuous duty applications. The S12R-T2-MPTK variant is specifically engineered for marine classification environments, delivering reliable high-output power within a compact and robust mechanical package that withstands the thermal cycling, vibration, and salt-air exposure inherent to marine service. At 1.2 MW, this new Mitsubishi S12R-T2-MPTK diesel engine delivers output suitable for main propulsion assistance, shaft generator arrangements, harbour tug prime movers, offshore supply vessel power, dredging operations, and heavy workboat continuous duty cycles. The engine's design priority is sustained full-load operation over extended durations, which is precisely the requirement profile of commercial marine operators who cannot tolerate derating or thermal shutdowns under operational load. This heavy marine diesel engine for sale through USP&E has been sourced from the manufacturer and is positioned for fast mobilisation to a buyer's project site or shipyard, with full technical documentation available to support classification society review and marine integration engineering. The continuous duty marine power unit configuration means this asset is ready to be integrated directly into a vessel's mechanical or electrical arrangement without the bridging modifications that older or surplus units typically require. Buyers seeking a heavy marine diesel engine for sale with a clear manufacturing date, new condition status, and immediate availability in the Asia region will find this listing exceptionally well-positioned relative to what is otherwise available on the secondary market.
USP&E brings more than a transaction to this asset. With over 150 completed power station projects across 45+ countries, USP&E is structured to deliver the full engineering, procurement, and construction scope around this new Mitsubishi S12R-T2-MPTK diesel engine, or to support its integration into a wider vessel or shore-power system. USP&E's EPC capability covers marine power system design, mechanical integration, fuel system engineering, cooling circuit installation, commissioning, and performance verification testing, all executed under the company's ISO 9001:2015 quality management certification and ISO 45001:2018 occupational health and safety framework. For operators who require ongoing support beyond initial installation, USP&E offers operations and maintenance contracts and long-term service agreements that keep continuous duty marine power units performing at nameplate output across their full service life. This marine EPC and O&M contractor capability is particularly valuable for buyers in frontier and emerging markets across Asia, Africa, the Middle East, and Southeast Asia, where OEM service infrastructure is limited and independent O&M support from a certified, OFAC and FCPA compliant contractor provides both operational security and regulatory confidence. Procurement is handled with USP&E's technical and commercial teams, reducing the delays and documentation gaps that complicate marine procurement in complex jurisdictions.
Buyers evaluating this new Mitsubishi S12R-T2-MPTK diesel engine should act without delay. New-condition, in-region, manufacturer-current marine diesel units at this output level are rarely available outside of direct OEM order books, and USP&E's ability to offer this asset with full EPC, O&M, and LTSA support attached makes this a procurement opportunity with genuine operational value beyond the hardware itself.
