Demand to reduce greenhouse gases from the marine sector is driving the market share for a marine propulsion engine
With almost 90% of global goods handled by sea, worldwide shipping contributes to nearly 3% of global CO2 emissions and industry is under increasing pressure to become cleaner. Several major corporations and organizations, including oil majors and port authorities, have urged the global shipping industry to be entirely decarbonized by 2050, asking governments to act quickly. By substituting renewable fuels for fossil fuels, major reductions in GHG emissions from marine engines can be accomplished. However, the supply of biofuels for transportation is limited.
Keeping hazardous GHG emissions to a minimum is a top priority. Moreover, it is also significant not to sacrifice ship engine performance and propulsion efficiency. Thus, to secure the future viability of their fleets, operators and ship owners are working on propulsion engines to minimize the carbon footprint of their vessels. Minimizing GHG emissions from marine propulsion needs a coordinated effort from all stakeholders, not only through the traditional development of its engines but also by bringing appropriate new technologies to the market.

In 2021, Van Oord installed UELSAVE FS MARINE, a patented solution to reduce the fuel consumption of marine diesel-powered engines and toxic emissions. The solution enables Van Oord to achieve substantial carbon dioxide, nitrogen oxide, particulate matter and black carbon reduction on existing ships.
Stringent environmental regulations create a huge challenging atmosphere for the growth of marine propulsion engines
Maritime transportation is regarded as the backbone of global trade. According to the International Chamber of Shipping (UK), roughly 90% of the sea’s global commerce trade is carried out. The marine mode of transportation is the most cost-effective than rail or road. Despite the advent of affordable and extensive air travel, cargo ships remain the primary mode of safe and reliable transport for large quantities of goods.
Consequently, the global marine shipping industry is the largest contributor to greenhouse gas emissions within the transportation sector. The ever-increasing global trade and rising marine freight transport volumes only increase greenhouse gas emissions. Governments and international organizations set strict environmental regulations to curb greenhouse gas emissions.
The intensity of emissions generated by dangerous gases such as SOx, NOx and CO2 varies by ship class. For example, the International Maritime Organization (UK) issued MARPOL Annex VI rules in 2005 that set NOx emission limitations and required the use of low-sulfur fuels. These regulations apply to vessels and ships operating on US seas and within 200 nautical miles of the North American coast, often known as the North American Emission Control Area (ECA). The EU has enacted similar emission laws for ships berthing in EU ports.
Marine propulsion engines mainly run on fossil fuels and cause significant greenhouse gas emissions. The stringent environmental regulations are a key challenge to the market’s growth.

COVID-19 Impact Analysis
The global marine propulsion engines market experienced a decline in 2020 owing to COVID-19’s impact. Governments globally imposed strict lockdowns and movement restrictions of varying durations starting from March 2020 to curb the spread of the emerging COVID-19 pandemic.
Due to the pandemic, global shipping came to a complete halt in 2020. Ports were closed and strict quarantine measures were implemented for international seafarers. The cruise industry completely collapsed due to the pandemic and cruise ships were berthed in ports worldwide. The COVID-19 pandemic severely impacted
The global shipbuilding industry is due to a near-complete collapse in demand. Many shipping companies postponed or canceled large capital expenditures due to the economic uncertainty brought on due to the pandemic. The completion of under-construction ships was delayed due to lockdowns and other movement restrictions. Only defense shipbuilding continued under restrictions since it is a critical part of national security, adding to the market growth during the pandemic phase.

Segment Analysis
The global marine propulsion engines market is segmented by engine type, ship type, application and region.
Diesel engine holds the highest market share in the global marine propulsion engine market due to excellent fuel efficiency and power
The global marine propulsion engines market is segmented into conventional, gas turbine, diesel engines and others. The diesel engine dominates the market of the mentioned engine types. With ships moving more than 70% of global freight, shipping is the most fuel-efficient freight transportation. Diesel engines, which are the most fuel-efficient, power most of them.
The most prevalent marine power technology is diesel, utilized in vessels, including small and leisure boats. The diesel propulsion engine can be found on many ships, ranging in size and purpose from small boats to massive oceangoing vessels. Since the first propelled ships, diesel engines have commanded the commercial ship industry (1912). Improvements over time, such as the switch to a two-stroke cycle, the addition of scavenging, turbocharging, direct coupling with the propeller and other structural changes, have allowed diesel engine propulsion systems to maintain their dominance in the field, owing to their economy, simplicity and dependability.
For economic reasons, the engines run on marine diesel oil or heavy fuel oil with high sulfur content. In various marine applications, customers benefit from the combination of diesel engines, electric motors and batteries. Efficiency, environmental compatibility and propulsion system flexibility are the most critical.
The four-stroke cycle diesel engine is used in medium to large merchant boats, with engine speeds ranging from 250 to 850 RPM. On vehicles with limited headroom, such as passenger ferries and boats, the engine is the preferred mode of propulsion.

Geographical Analysis
The presence of a majority of the cargo ships utilizing diesel combustion engines for propulsion in Europe escalates the product demand in the region
The European Regulation 2016/1628 has been a major standard in the region for engines intended for non-road machinery, including marine engines. The purpose of NRMM regulation is to reduce air emissions from inland waterways. The NRMM Regulation sets out limit values for carbon monoxide emissions, hydrocarbons and nitrogen oxides for inland waterway engines. In addition to the weight of particulate matter (PM) requirements, it has also been chosen to set standards for the number of solid particulate particles. PM emissions are 92.5% and Nox emissions by 70-84% lower than current requirements for CCR-II engines. In 2019, all-new engines for inland waterway vessels needed to comply with the Stage V emission requirements of the European Union for NRMM.
