The marine diesel engine market is experiencing implementations of several strategic approaches, such as collaboration, mergers & acquisitions, expansion, and product launches. Major industry players are making strategic investments in research and development activities and fostering their expansion plans. 

For instance, recently, on June 19, 2021, IIT Roorkee and Indian Maritime University (IMU Visakhapatnam) announced the development of environmentally friendly, and fuel and cost-efficient maritime transportation solution. India’s broad coastline witnesses several new ports and expansion of existing ports meeting increased volumes of marine traffic and facilitate future maritime trade.

Growing seaport infrastructure requires more Short Endurance Marine Vessels (SEMV) for effective port operations and administration. The usable life of a diesel-engine-driven SEMV is nearly 20 years. During its operating life, the vessel requires regular maintenance with expensive operational costs and releases harmful carbon emissions.

To provide sustainable solutions and reduce carbon footprint at Indian seaports, diesel-engine-driven marine vessels must be replaced with zero-emission electric vessels. However, replacing diesel engines with electric ones is a costly affair. Therefore, these researchers have successfully improved the fuel efficiency of diesel-electric tugboats. Fuel savings obtained by the above methods were 29.86% and 26.42% respectively, as against the traditional diesel-mechanical tugboat propulsion system.

Rapid & Excessive Growth in Marine Trades is a Major Driving Force

Besides, product standardization enhanced research & innovation, and increased lab & field tests are significant marine diesel engine market trends ensuring market growth. Huge R&D investments made by industry players in developing efficient engines that can reduce harmful gases emitted from diesel engines would influence the market growth. 

The worldwide rise in economy and excessive demand for various commercial vessels such as different bulk carriers and several gas carriers has undoubtedly spurred the marine diesel engine market growth. Emerging markets worldwide are expected to present untapped opportunities for marine diesel engine uses. With their favorable government policies for diesel engine manufacturing, emerging countries offer significant opportunities to international players.

Stringent Government Regulations and Maintenance Issues are Major Setbacks

Despite significant growth prospects, the market witnesses major setbacks such as, stringent government regulations against harmful carbon emissions from diesel engines and maintenance issues related to diesel engines.  Also, the growing preference for natural gas generator technology acts as a major challenge for the market growth.
