Marine Gensets Market Report 2026

The marine gensets market size has grown steadily in recent years. It will grow from $5.2 billion in 2025 to $5.43 billion in 2026 at a compound annual growth rate (CAGR) of 4.3%. The growth in the historic period can be attributed to growth in global maritime trade, expansion of commercial shipping fleets, rising offshore oil and gas activities, increasing demand for onboard power reliability, adoption of diesel based marine power systems.

The marine gensets market size is expected to see steady growth in the next few years. It will grow to $6.33 billion in 2030 at a compound annual growth rate (CAGR) of 3.9%. The growth in the forecast period can be attributed to implementation of stricter emission regulations, rising adoption of lng and hybrid powered vessels, growth in cruise and ferry transportation, increasing digitalization of marine power systems, investments in next generation marine propulsion and power infrastructure. Major trends in the forecast period include increasing adoption of low emission and alternative fuel gensets, rising integration of digital monitoring and control systems, growing demand for high power and reliable marine gensets, expansion of hybrid and energy efficient power solutions, increasing focus on compact and modular genset designs.

The strong growth in seaborne trade is expected to drive the expansion of the marine genset market in the future. Seaborne trade refers to the movement of goods and commodities across global oceans and seas using commercial ships. This trade is growing due to rising globalization and international trade, which increase the demand for efficient, large-scale transportation of goods across continents. Marine generators are essential for seaborne trade, providing reliable onboard electrical power for navigation, communication, lighting, refrigeration, and other vital systems on ships and vessels. For example, in July 2023, a report by the United Nations Conference on Trade and Development (UNCTAD), a Switzerland-based intergovernmental body, noted that maritime trade volume shrank by 0.4 percent in 2022, but UNCTAD predicts a 2.4 percent growth in 2023. As a result, the continued growth of seaborne trade is fueling the demand for marine gensets.

Key players in the marine genset market are innovating with products such as lightweight gensets to meet customer demands for advanced features. Lightweight gensets are designed for portability and ease of transport, catering to various marine applications. For example, Cummins Inc., a US-based power solutions company, introduced the Marine Diesel Cummins Turbo (MDCT) genset in May 2023. This genset is versatile, offering power options ranging from 40 kWe to 110 kWe with the Cummins B4.5 auxiliary engine, suitable for both commercial and recreational marine uses. It features a compact design, compliance with EPA Tier 3 and EU Stage V emissions regulations, and user-friendly diagnostics through the Cummins Onan Digital Display.

In October 2025, VINCI Energies, a France-based provider of energy and information technology services, acquired Marine Electrical Systems from Wärtsilä Corporation for an undisclosed sum. Through this acquisition, VINCI Energies aims to bolster its presence in the marine sector by enhancing its expertise in complex electrical systems integration and expanding its range of specialized maritime solutions. Wärtsilä Corporation is a Finland-based company specializing in the manufacture of marine gensets and a wide array of generating sets for marine applications, including diesel and dual-fuel gensets.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

Tariffs have impacted the marine gensets market by increasing costs of imported engines, alternators, and electronic control components used in genset manufacturing. These effects are most visible in asia pacific and european shipbuilding regions that rely heavily on cross border component sourcing. Higher tariffs have pressured pricing and extended procurement timelines for commercial and offshore vessels. At the same time, tariffs have encouraged localization of manufacturing, supplier diversification, and innovation in cost efficient and fuel flexible marine genset solutions.

Marine gensets are power generation units specifically engineered for use on a variety of vessels, including ships, boats, and offshore platforms. These gensets supply electrical power for essential onboard applications such as lighting, navigation equipment, communication systems, and other electrical systems.

The primary fuels used in marine gensets include marine diesel oil (MDO), marine gas oil (MGO), liquefied natural gas (LNG), hybrid systems, and other fuel types. Marine diesel oil (MDO) is a fuel oil blend used in ships, comprising a mix of heavy fuel oil and marine gas oil. Gensets are available in various power ratings categorized as < 1,000 kW, 1,000 kW-5,000 kW, 5,000 kW-10,000 kW, 10,000 kW-20,000 kW, and >20,000 kW. They are utilized across different types of vessels including defense vessels, commercial vessels, offshore vessels, and others, serving applications in merchant shipping, offshore operations, as well as cruise and ferry industries.Asia-Pacific was the largest region in the marine gensets market in 2025.
