These environment-friendly engines are ideal for passenger and cargo vessels engaged in short-distance maritime transportation. With technological advancements, the operational range of electric vessels is increasing steadily, offering greater feasibility. Leading engine manufacturers are proactively developing hybrid and electric product variants.
They are also receiving favorable government policies and incentives for eco-friendly marine initiatives. This shifts the market dynamics in favor of alternate propulsion systems and generates massive business prospects.
Diesel engines contribute the 54.8% share of the global marine propulsion engine market in 2025 owing to their reliability and efficiency. Diesel engines have been the workhorse of marine propulsion for decades due to their ability to deliver high power outputs even under heavy loads for extended periods of time. Ship owners and operators have come to rely on diesel engines to power their fleets in a cost-effective manner without compromising on performance.
Diesel engines offer various advantages over other engine types. They are highly fuel efficient, with typical fuel consumption rates 20-30% lower than alternatives. This directly reduces operating costs for shipowners. Diesel engines also require relatively inexpensive heavy fuel oil as fuel, keeping fuel costs low. Their mechanical design is simpler than gas turbines, requiring less maintenance and downtime. Reliability is extremely high even in punishing marine environments with saltwater, moisture and vibrations. This reliability and uptime are crucial for shipping operations.
Manufacturers have also continually improved diesel engine technology. The introduction of common rail fuel injection systems and electronic engine management has boosted efficiency and power output. Emission regulations have led to the adoption of exhaust gas recirculation and selective catalytic reduction systems, allowing diesel engines to meet stringent environmental standards. Automation has decreased manning requirements. These advancements have cemented diesels as the first choice for marine propulsion.
With established global supply chains and experienced shipbuilding yards, diesel engines also benefit from economies of scale in their production. This allows aggressive pricing without compromising on quality. As a result, diesel engines capture the highest share across sectors such as tankers, bulk carriers and container ships that prioritize workhorse propulsion for international voyages. Their reliability makes them dominant in the global marine propulsion engine market.
The segment of engines with power output less than 10,000 kW captures the 43.6% share of the global marine propulsion engine market in 2025. This is driven by the need for propulsion systems with low initial and operating costs that are suitable for smaller vessels.
Engines in the less than 10,000 kW range are often used to power coastal and inland waterway vessels such as tugs, offshore support vessels, fishing trawlers and ferries. These vessels have smaller hull sizes and lower cargo volumes compared to ocean-going carriers. Their operations involve shorter distances, turnarounds in ports and higher maneuvering needs near coastlines.
Given their operating profile, lower capital and running costs take priority over ultra-high power outputs. Engine manufacturers optimize designs in this segment for affordable pricing, fuel efficiency and easy maintenance tailored to smaller shipyards. They are also compact with a higher power-to-weight ratio for maneuverable installations.
Operating expenditures, mainly fuel costs, constitute a major portion of the total cost for owners and operators in this sector. Lower power engines in the range of a few thousand kW consume less fuel. They also have maintenance schedules aligned to uptime requirements for coastal operations rather than long transits. This significantly reduces operational expenses.
The price points of engines below 10,000 kW, starting from just a few hundred thousand dollars, also fit well within the investment budget of smaller vessel owners. As such, their compatibility with technical and commercial requirements makes them the highest selling segment.
Within fuel types, heavy fuel oil (HFO) contributes the 47.3% share in 2025. Although more pollutive than alternatives, HFO remains dominant due to its wide availability and substantially lower price point compared to other marine fuels.
Most ocean-going vessels today use HFO to power their main and auxiliary engines. It is thick, cheap, and energy dense, offering a higher calorific value than alternatives. Manufacturers design propulsion engines, especially large two-stroke crosshead diesel engines, to efficiently burn this low-quality fuel. Since international shipping regulates emissions rather than fuels, HFO remains compliant for marine use if vessels have abatement systems.
At approximately half the price of next best fuels, the operational cost benefits of HFO are unparalleled. Even with higher dilution and processing costs compared to cleaner fuels, savings from fuel expenditure translate directly to higher profitability. For cost-sensitive international bulk shipping, hinging propulsion on cheap HFO makes strong economic logic.
Availability and storage infrastructure for HFO are universal across all major ports. Established global supply chains ensure Just in Time bunkering without disrupting schedules. Alternatives lack this distribution reach today. As the incumbent fuel with decades of usage history across most engine designs and ship types, HFO also possesses massive scale advantages.
While facing pressures to gradually adopt cleaner fuels, HFO remains dominant driven by its competitive pricing and compatibility with the needs of cost-conscious global maritime trade. That pushes its share to the highest in this segment.
