Insights By Engine Type - Dominance of Reliability and Efficiency, Diesel Engine contributes the highest share of the market
Diesel engines contribute the 54.3% share of the global marine propulsion engine market in 2024 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.
