第15章 調査会社について・免責事項

The Global Shaft Generator System Market was valued at USD 321.9 million in 2024 and is projected to reach USD 473.9 million by 2030, growing at a CAGR of 6.5% during the forecast period. Market growth is primarily driven by the maritime industry's focus on reducing emissions and enhancing fuel efficiency in response to stringent global environmental regulations. Shaft generator systems, which utilize the ship's main engine to generate electrical power, help reduce dependency on auxiliary generators, thus improving energy efficiency and cutting fuel costs. Advancements in permanent magnet technologies and variable frequency drives are further boosting system performance, reliability, and integration in hybrid propulsion setups. The retrofitting of vessels to meet regulatory compliance and achieve cost savings presents significant growth opportunities. Moreover, the Asia-Pacific region is witnessing rapid adoption, supported by robust shipbuilding industries and favorable green policy frameworks. These factors collectively underscore the growing importance of shaft generator systems in enabling cleaner and more efficient maritime operations.

Key Market Drivers

Stringent Environmental Regulations and Emission Reduction Mandates Driving Demand

The growing emphasis on sustainability within the maritime sector, driven by international environmental mandates such as IMO MARPOL Annex VI, is a key driver for the global shaft generator system market. These regulations require ships to significantly reduce emissions of sulfur oxides (SOx), nitrogen oxides (NOx), and greenhouse gases, prompting the adoption of cleaner onboard power solutions. Shaft generator systems help vessels meet these requirements by converting mechanical energy from the propulsion shaft into electrical energy, thereby minimizing reliance on auxiliary generators and reducing fuel consumption. This leads to lower operational emissions, aligning with global decarbonization efforts, including the IMO's target of reducing GHG emissions by 50% by 2050 and the EU's 2030 Green Deal targets. As a result, ship operators are increasingly investing in shaft generator technologies to achieve compliance while benefiting from improved fuel economy.

Key Market Challenges

High Initial Investment and Installation Costs Hindering Market Adoption

A major challenge hindering widespread adoption of shaft generator systems is the high upfront cost associated with their purchase and installation. The technology requires precise integration with the ship's main propulsion system, which often involves custom engineering and specialized components. For both new builds and retrofits, this leads to significant capital expenditures. Installation typically demands dry-docking, specialized labor, and extended downtime, which can disrupt vessel operations and incur revenue losses. Additionally, ongoing maintenance of components such as permanent magnet generators and advanced control units requires technical expertise, which may not be readily available in all regions. These cost and logistical barriers can deter adoption, particularly among operators of older or smaller vessels.

Key Market Trends

Adoption of Permanent Magnet Shaft Generators for Enhanced Efficiency and Compact Design

A notable trend shaping the market is the rising preference for permanent magnet (PM) shaft generators. These systems leverage high-strength rare-earth magnets, resulting in more efficient and compact designs compared to traditional generators. Their lightweight and space-saving characteristics are particularly beneficial for modern vessels with limited room for auxiliary equipment. PM generators are also capable of delivering consistent power across a broader range of engine speeds, which enhances performance and fuel efficiency in variable-speed propulsion systems. This capability supports the maritime industry's transition toward hybrid and energy-optimized operations. Furthermore, the modularity and ease of integration of PM shaft generators make them increasingly attractive for both new shipbuilding projects and retrofitting initiatives aimed at improving sustainability and operational performance.
