Offshore Support Vessel Market Report 2026

The offshore support vessel market size has grown strongly in recent years. It will grow from $29.85 billion in 2025 to $31.94 billion in 2026 at a compound annual growth rate (CAGR) of 7%. The growth in the historic period can be attributed to growth of offshore oil and gas exploration, expansion of offshore drilling activities, increasing need for logistics and platform support, development of deepwater fields, reliance on conventional offshore vessels.

The offshore support vessel market size is expected to see strong growth in the next few years. It will grow to $41.51 billion in 2030 at a compound annual growth rate (CAGR) of 6.8%. The growth in the forecast period can be attributed to growth of offshore wind installations, increasing offshore maintenance activities, rising demand for advanced support vessels, investments in offshore energy projects, focus on safety and cost efficiency. Major trends in the forecast period include rising demand for multi-purpose support vessels, increasing utilization in deepwater and ultra-deepwater operations, growing focus on fleet modernization, expansion of offshore wind support activities, rising emphasis on operational efficiency.

The increasing global energy demand is expected to drive growth in the offshore support vessel market. Energy is the capacity to cause change or perform work, and rising worldwide demand has led to greater exploration efforts in offshore locations. Offshore support vessels are essential for transporting personnel, equipment, and supplies to and from offshore rigs and platforms. For example, in August 2023, ExxonMobil Corporation, a U.S.-based oil and gas company, projected that global energy demand would reach approximately 660 quadrillion British Thermal Units (Btu) by 2050, representing an increase of around 15%. Therefore, the growing global energy demand is fueling the offshore support vessel market.

Key players in the offshore support vessel sector are prioritizing the development of pioneering solutions, notably the Marine Advisory System Operational Planner, aimed at ensuring dependable services for customers. This specialized software module is tailored to enhance the efficiency of offshore operations, specifically for wind farms and diverse marine installations. A notable instance is witnessed in June 2023, when ABB Ltd., a renowned technology company based in Switzerland, introduced the OCTOPUS - Marine Advisory System Operational Planner for offshore support vessels. This software suite serves as a comprehensive tool, leveraging real-time data and insights pertaining to crucial factors such as weather conditions, sea state, and vessel motions, thereby optimizing the operational performance of offshore vessels.
