The Asia, Latin America & Middle East Marine Generator Set Market is expanding rapidly, driven by robust maritime activity. Growth is especially strong in China, whose genset installations grew from ~1,964 units in 2018 to ~2,223 units in 2020 Market momentum is fueled by rising domestic vessel power needs—AC, propulsion, galley systems—and a steady surge in ship construction revenue (≈ USD 56 billion in 2019) .

Similarly, Japan remains a powerhouse, delivering ~12.94 million GT in 2020 despite pandemic related dips, maintaining its position as a top three global shipbuilder Other Asian nations—South Korea, Singapore, Indonesia, Vietnam—contribute to this marine engine boom
