The offshore support vessels (OSV) market continues to expand steadily, driven by rising offshore oil and gas exploration, increasing offshore wind farm installations, and renewed investments in deepwater projects. The offshore support vessels market size reached USD 19.01 Billion in 2025 and is projected to grow at a CAGR of 6.80% between 2026 and 2035, reaching almost USD 36.70 Billion by 2035. Growing demand for reliable offshore logistics, subsea operations, and maintenance services is strengthening long-term industry prospects. As energy companies diversify into offshore renewables alongside traditional hydrocarbon exploration, the demand for advanced support vessels is accelerating globally.
Offshore Support Vessels Market Overview
Offshore support vessels are specialized ships designed to assist offshore oil rigs, platforms, subsea construction projects, and renewable energy installations. These vessels perform a wide range of functions including transportation of crew, supply of equipment and fuel, anchor handling, towing, subsea inspection, and emergency response services.
The OSV market includes various vessel types such as platform supply vessels (PSVs), anchor handling tug supply vessels (AHTS), subsea vessels, crew boats, and construction support vessels. Each vessel category serves specific operational needs in offshore energy production and infrastructure development.
Historically, the offshore oil and gas industry has been the primary driver of OSV demand. However, the rapid expansion of offshore wind energy projects is reshaping the market landscape. Offshore wind farms require specialized vessels for installation, maintenance, and cable-laying operations, opening new growth avenues.
The market is influenced by global energy demand, oil price fluctuations, exploration budgets, and regulatory frameworks governing offshore safety and environmental compliance.
Offshore Support Vessels Market Size
The global offshore support vessels market reached a value of USD 19.01 Billion in 2025, reflecting increased offshore drilling activities and investments in marine infrastructure. After experiencing volatility during periods of oil price fluctuations, the market has stabilized due to renewed offshore exploration projects and diversification into renewable energy support.
The market is projected to grow to nearly USD 36.70 Billion by 2035, supported by a CAGR of 6.80% during 2026-2035. The steady growth trajectory indicates strong demand from both traditional offshore oil projects and emerging offshore wind energy developments.
Regions such as the North Sea, Gulf of Mexico, Middle East, and Asia-Pacific continue to account for significant OSV activity, while new offshore wind installations in Europe and Asia are contributing to incremental demand.
