The increasing import and export activities across the globe has put a greater emphasis on enhancing the capacity of diesel propulsion engines to prosper the growth of new-generation tankers with higher cargo holding capacity. Further, rapid depletion of conventional and shale gas reserves has prominently boosted the demand for LPG gas in marine fuel. Previously, steam turbine systems were largely preferred for marine propulsion, whereas for increasing the utilization of natural gas, the dual-fuel diesel (DFD) propulsion engines were introduced on LNG carriers.

• The demand in international trade and shipping increased the demand for efficient marine propulsion systems with the best power, and hence, the demand for the shipbuilding industry that has advanced technology-driven installation of such engines.
• The shift towards eco-friendly fuels is being made due to the public concern about the environment and the imposition of tighter pollution regulations.
• The expansion of offshore drilling and mining has come along with the demand for good-quality and powerful marine engines that can stand the tough conditions.
• One of the main benefits of propulsion technologies is technological advancements that make the system more reliable, less costly, and at the same time, open up the possibility for sustainable maritime operations.

Market Scope

Product Insights

Based on product, the marine propulsion engines market is classified into the wind & solar propulsion engine, diesel propulsion engine, fuel cell propulsion engine, gas turbine propulsion engine, natural gas propulsion engine, steam turbine propulsion engine, and others. In the past decade, diesel propulsion engine has emerged as the prominent source of propulsion in the shipping industry. With the rising advancements in the technology and increasing preference for sustainable propulsion system alternate energy sources for example renewable energy that has minimal emission rate has garnered significant penetration in the shipping industry. This in turn accelerates the market growth for wind and solar marine propulsion engine.

Although solar and wind marine propulsion engine has gained importance as the auxiliary propulsion engine, they are insufficient to meet the power requirement for primary marine propulsion purpose. Wind propulsion systems are limited for propulsion augmentation applications if full sail propulsion method is adopted that gives rise to adverse commercial and financial implications in terms of voyage time taken and number of ships required. In addition, wind-based propulsion is dependent on the speed of wind that should be uniform and effective to sail a ship coupled with the installation of suitable control system technology in the ship. Hence, wind and solar propulsion engines witness magnificent growth as the auxiliary system as they are environment friendly and do not emit harmful substance in the environment.

Apart from the shift for renewable energy in marine propulsion system, developments in fuel injection technology, firing pressure, brake mean effective pressure, and turbo-charging efficiency have drastically reduced the fuel consumption in marine industry. This has significantly triggered the adoption of natural gas and diesel propulsion engines in the marine industry.

Key Companies & Market Share Insights
