Offshore Support Vessels Market Analysis by Mordor Intelligence
The offshore support vessels market size is projected to expand from USD 23.08 billion in 2026 and USD 24.95 billion in 2027 to USD 36.36 billion by 2032, registering a CAGR of 7.82% between 2027 and 2032.
Committed offshore work in Brazil and the United Arab Emirates supports marine-service demand, while wind expansion creates assignments for service operation vessels. Operators respond through fleet additions, asset rotation and long-term charters, tying investment to the work that vessels can secure. High replacement costs and oil-price uncertainty temper that response by increasing capital exposure and shortening the revenue commitments available to owners. Suppliers combining suitable vessels with offshore service execution can capture a broader contract scope, making deployment and contractual responsibility central to returns.

Up-cycle in offshore E&P CAPEX
Sanctioned offshore infrastructure spending creates marine-support demand as capital commitments move into field development. In July 2026, ADNOC made a USD 6.2 billion final investment decision to develop the Umm Shaif Gas Cap at an offshore field in Abu Dhabi, United Arab Emirates.[1] The development includes 3 engineering, procurement and construction packages totaling USD 5.1 billion for offshore infrastructure. A USD 365 million drilling program is also a component of the development commitment. Infrastructure construction and drilling together create distinct requirements for offshore execution, giving vessel operators exposure to multiple workstreams within a single sanctioned development.
Accelerating offshore wind installations
Wind-farm expansion supports vessel demand through new connections and the subsequent commitment to maintaining generating assets. GWEC reported 9.3 GW of new grid-connected offshore wind capacity worldwide in 2025, up 16% from 2024 and the third-highest annual total on record. In August 2025, RWE agreed North Star charters of at least 12 years for Grampian Eagle at Britain’s Triton Knoll and at least 10 years for Grampian Kestrel at German wind farms north of Heligoland. Each charter included an option for up to 3 additional years. Such commitments connect the installed wind base to recurring operations and maintenance revenue for service-vessel operators. Minimum terms of 10 and 12 years commit vessel capacity to RWE’s wind farms well beyond construction, so charter demand follows the operating fleet rather than installation schedules.
Stricter decommissioning mandates
Decommissioning obligations create a vessel-service requirement that extends beyond the revenue-producing life of an offshore asset. In August 2025, Brazil’s ANP rejected Petrobras’ request to delay the start of floating storage and offloading (FSO) unit Cidade de Macaé’s 6-month executive decommissioning-program deadline until all 3 agencies approved the conceptual program.[2] ANP held that its own conceptual approval starts the deadline, with the completed executive program then submitted to ANP, the Navy and Ibama. That sequence limits the operator’s ability to defer preparation while awaiting separate agency decisions. OSPAR’s Agreement 2024-04 guidance made full removal the primary objective under Decision 98/3 before alternative disposal options are considered. Enforceable planning deadlines and removal-first objectives therefore turn retirement obligations into scheduled vessel work.
Surge in floating production systems (FPSO, FLNG)
Final investment decisions (FIDs) for floating production and floating liquefied natural gas (FLNG) units create vessel opportunities beyond installing a single offshore structure. On June 22, 2026, Azule Energy reached FID for Angola’s Greater PAJ development, comprising 17 wells connected to a new floating production, storage and offloading (FPSO) vessel rated at 95,000 barrels of oil per day. The associated well development makes the production vessel part of a wider offshore execution program. On June 3, 2026, Delfin Midstream took FID for its first FLNG vessel in Louisiana and offshore the Gulf of America, with expected LNG export capacity of 4.4 million metric tons annually. The commitments cover oil production and gas liquefaction, broadening the offshore facilities around which marine-service requirements can develop. Both decisions fix project scope in 2026, so vessel demand follows named development programs rather than general market conditions.
Restraints Impact Analysis of Offshore Support Vessels Market*
| Restraint | (~) % Impact on CAGR Forecast | Geographic Relevance | Impact Timeline |
|---|---|---|---|
| High oil-price volatility | -1.2% | Offshore production areas in Malaysia | Short term (≤ 2 years) |
| Capital-intensive newbuild costs | -1% | North America, Europe and Asia-Pacific | Long term (≥ 4 years) |
| Shortage of experienced crew | -0.6% | Europe, South America and Asia-Pacific | Short term (≤ 2 years) |
| Limited yard capacity & high steel prices | -0.4% | North America, Europe and Asia-Pacific | Medium term (2-4 years) |
| Source: Mordor Intelligence | |||
High oil-price volatility
Oil-price uncertainty can constrain the length of charter commitments as well as the spending attached to them. In its 2025 Malaysian market review, Perdana Petroleum said volatility, alongside geopolitical and trade pressures, drove cautious customer spending and shorter contract tenures. Shorter agreements leave fewer future vessel days covered by a signed revenue commitment. Each expiry also brings the next charter negotiation forward, exposing the operator sooner to prevailing customer demand. Malaysian vessel operators such as Perdana consequently face more frequent repricing and the risk of employment gaps while carrying the cost of keeping vessels available.
Capital-intensive newbuild costs
The cost of replacing offshore tonnage creates a barrier between demand for vessel services and investment in additional capacity. In 2025, 37 platform supply vessels (PSVs), anchor handling tug supply vessels (AHTSs) and high-speed supply and crew transport vessels were ordered globally, 58% fewer than in 2024. High construction costs, market uncertainty and tight yard capacity contributed to that contraction. A large 5,200-dwt PSV was valued at USD 60 million in 2025, up 7.1% year to date, while a 24,000-bhp AHTS reached USD 82 million, up 6.8%. Because construction precedes earning from the vessel, owners carry capital exposure before service revenue begins. Fleet renewal therefore depends on charter terms strong enough to support replacement costs, slowing how quickly service demand can produce new capacity.

Offshore Support Vessels Market Segment Analysis
By Vessel Type:
Working Fleet Scale and Contracted Subsea DemandAnchor handling tug/anchor handling towing supply vessels (AHT/AHTSs) accounted for a 42.15% share of the offshore support vessels market size in 2026, making them the largest vessel-type segment. China Oilfield Services Limited (COSL) recorded 20,918 AHTS operating days in the first half of 2026, up 2.3% year over year and the highest total among its marine-support vessel categories. The company’s marine-support fleet recorded 43,814 operating days in total over that period. Anchor-handling vessels therefore represented COSL’s largest block of vessel employment, with modest growth on an already substantial working base.
Other types (MPSV, subsea, standby crew) form the fastest-growing segment, with a forecast CAGR of 9.25% between 2027 and 2032. In May 2026, DOF Group ASA won 12-year contracts worth close to USD 2 billion for 4 Brazilian remotely operated vehicle (ROV) support newbuilds serving Petrobras deepwater inspection, maintenance and repair, with commencement expected from 2030.[3] DOF Subsea Brasil is responsible for the contracts, operations and services. In August 2026, DOF Group ASA announced 2 Asia-Pacific subsea contract awards using the region’s multipurpose vessels and subsea services for campaigns across 2026 and 2027, with an estimated combined duration of approximately 80 days. The Brazilian newbuild contracts defer service revenue until expected starts from 2030, whereas shorter Asia-Pacific campaigns offer vessel employment in 2026 and 2027.
By Application:
Producing Fields Anchor Demand as Wind Capacity ExpandsOffshore oil and gas represented a 49.65% offshore support vessels market share in 2026, making it the largest application segment. Norway had 97 producing fields at the end of 2025, spread across the North Sea, Norwegian Sea and Barents Sea. This operating footprint gives marine-service suppliers a geographically dispersed base of offshore assets to support. Production on the Norwegian Continental Shelf totaled 239.2 million standard cubic meters of oil equivalents in 2025, with gas accounting for more than half. For suppliers serving Norway, gas-led output makes exposure to the producing base broader than oil production alone.
Offshore wind is the fastest-growing application segment, with a forecast CAGR of 15.4% between 2027 and 2032. In October 2026, Kongsberg Maritime secured a contract with IWS Fleet AS, an Integrated Wind Solutions subsidiary, for design and integrated technology for 4 new commissioning service operation vessels. The first delivery is due in 2029, and the vessels are designed for wind-farm commissioning, operations and maintenance. Combining these duties links additional vessel capacity to both project start-up and the subsequent service phase. The growth opportunity therefore carries delivery exposure, because a design-and-equipment commitment must become an available vessel before it can generate offshore service revenue.
Geography Analysis
North America Offshore Support Vessels Market
North America accounted for a 33.56% offshore support vessels market share in 2026, making it the largest region. Oil production averaged 1.981 million barrels per day across the Central and Western Gulf of America planning areas in July 2026. In June 2025, Oceaneering’s Offshore Projects Group agreed vessel services for an operator’s expected Gulf of America subsea inspection, maintenance, repair and installation work using MPSV Harvey Deep Sea. Oceaneering was the charterer, with its charter then extending through February 2027. The combination of a producing base and contracted subsea work supports service opportunities tied to maintaining offshore operations as well as developing them.
Asia-Pacific Offshore Support Vessels Market
Asia-Pacific is the fastest-growing region, with a forecast CAGR of 8.9% between 2027 and 2032. In May 2026, Numero Uno Marine and Transport announced 2 time-charter awards from Brunei Shell Petroleum for dynamic positioning class 2 (DP2) platform supply vessels supporting offshore operations in Brunei. In September 2026, Nippon Yusen Kabushiki Kaisha ordered one service operation vessel for offshore wind construction and maintenance in Taiwan and wider Asia-Pacific, with delivery planned around 2029. Regional expansion consequently has 2 distinct demand channels, combining supply-vessel awards for oil and gas campaigns with investment in dedicated wind-support capacity.
Europe’s North Sea wind farms create a role for service operation vessels (SOVs) that remain offshore for several days. Vattenfall’s 2025 contract with Louis Dreyfus Armateurs covered building, owning and operating up to 3 SOVs for operations and maintenance, with service intended from 2027. In South America, OceanPact’s August 2025 Petrobras charters covered 4 ROV support vessels (RSVs) for 4 years of subsea inspection, maintenance, equipment installation and removal, including vessel and ROV operation. The Middle East and Africa supplier base includes Abu Dhabi-based ADNOC Logistics & Services, which reported expanded offshore support vessel (OSV) chartering in 2025 and wholly owns OSV operator Zakher Marine International Holdings. Vattenfall buys wind maintenance capacity and Petrobras charters subsea vessels, while ADNOC Logistics & Services integrates vessel ownership through a subsidiary, so counterparties range from asset operators to logistics groups.
Regulatory Framework and Outlook
This comparison examines selected jurisdictions from the perspective of an offshore vessel-service operator entering each jurisdiction without a locally established operating entity. Company authorization, vessel certification and emissions duties affect different parts of that operating model, from establishing the supplier to keeping a ship eligible for work. Flag, gross tonnage (GT), activity and route conditions determine which obligations apply to a particular vessel. From reporting year 2027, the flag-neutral EU ETS covers offshore ships of at least 5,000 GT, including full emissions between EU ports and within EU ports and half between EU and non-EU ports.
Regulatory Table of Offshore Support Vessels Market
| Decision factor | United States | Germany | China | Brazil | Saudi Arabia |
|---|---|---|---|---|---|
| Primary authority | U.S. Coast Guard | DEHSt at the Federal Environment Agency, for maritime emissions trading | Maritime administrations under the Ministry of Transport | ANTAQ | Transport General Authority |
| Key instruments or direction | 46 CFR Subchapter L for offshore supply vessels | German-flag emissions reporting; FuelEU Maritime for commercial passenger or cargo ships above 5,000 GT calling at EU ports | Ship Safety Supervision Rules and company safety-system duties | Resolution 133/2025 navigation-company authorization | Safety-management regulation for Saudi-flag ships in listed classes |
| Commercial effect | Vessel inspection and certification obligations | GHG-intensity and monitoring duties for qualifying ships; German-flag reporting | Safety and pollution-prevention systems; inspections of in-scope Chinese and foreign ships in Chinese waters | Brazilian-established and administered company must meet technical, economic and legal criteria; authorization takes effect on publication of its term in the Official Gazette | Applicable safety and pollution-prevention duties for Saudi-flag cargo-class OSVs of at least 500 GT |
| Current policy attractiveness | Medium | Medium | Medium | Low | Medium |
| Future direction of policy attractiveness | No change | Hardening | No change | No change | No change |
| Source: Mordor Intelligence | |||||
Medium and No change for the United States, China and Saudi Arabia reflect operative inspection and safety frameworks, with United States coastwise eligibility also restricting work that requires an endorsement. Brazil’s Low rating reflects the need to establish and administer a Brazilian company and obtain ANTAQ authorization under Resolution 133/2025, effective upon publication of the authorization term in the Official Gazette. In September 2026, ANTAQ’s time-charter review was a draft under deliberation for public participation, so No change describes the operative authorization framework rather than a direction for that proposal. Germany’s Medium rating reflects emissions reporting, while Hardening reflects the adopted 2027 EU ETS extension and allowance duties for offshore ships of at least 5,000 GT within covered EU-linked voyages and ports.
Value Chain Stages
This value chain compares how vessel design, construction, equipment integration and charter operations turn offshore requirements into supplier revenue. Damen’s October 2025 contract with Chomex Marino covered 2 offshore support tugs for Woodside Energy’s planned Mexican operations, following Woodside’s tender for a 15-year time charter contract. Connecting vessel specifications to a defined charter duty aligns the construction decision with the intended service, while delivery and operating risks require separate contractual treatment.
Value Chain Analysis Table of Offshore Support Vessels Market
| Primary activity | Key participants | Value capture | Bottleneck | Resilience response |
|---|---|---|---|---|
| Vessel design | Vessel designers such as MMC Ship Design, Damen Shipyards Group and VARD, a Fincantieri subsidiary | Design work within vessel-build contracts | Mismatch between intended offshore duty and vessel specification | Define charter duty before freezing the design |
| Hull construction and outfitting | Shipbuilders such as CRIST, Damen Shipyards Group and VARD | Vessel construction sales | Delivery-schedule exposure across fabrication and outfitting | Coordinate hull and final outfitting milestones |
| Equipment integration | Marine equipment suppliers such as Kongsberg Maritime | Equipment-package sales | Interface risks between ship systems and vessel design | Assign system-integration responsibility before equipment procurement |
| Vessel charter and service delivery | Vessel owners and operators such as DOF Group ASA and Seacor Marine Holdings Inc. | Charter hire and service-contract revenue | Unassigned vessel days and operating-cost exposure | Align charter duration and cost allocation with vessel employment |
| Source: Mordor Intelligence | ||||
Seacor Marine Holdings Inc. recognizes vessel revenue daily through hire rates under time and bareboat charters. Under its time charters, it pays operating expenses, typically excluding fuel, while bareboat customers assume operating expenses and operating risks. For the same owned vessel and daily hire, a time charter leaves Seacor bearing running costs that bareboat customers pay, so its earnings exposure differs by charter form.
Competitive Landscape
Competition combines multinational fleet groups with providers of specialized vessel duties, creating a differentiated and moderately fragmented supplier base. BOURBON Maritime SAS operates platform supply and anchor-handling vessels, while DOF Denmark A/S provides offshore marine services as a subsidiary of DOF Group ASA. Seacor Marine Holdings Inc. supports transportation, construction and subsea work worldwide, while Edison Chouest Offshore LLC operates supply and multipurpose vessels for global and U.S. Gulf deepwater requirements. In April 2026, BOURBON reported adding 13 offshore support vessels since the start of the year, valued at more than USD 180 million. BOURBON’s 13 additions in under 4 months demonstrate rapid fleet expansion, while Edison Chouest’s multipurpose vessels and Seacor’s subsea services distinguish their offers by the work they can perform.
Fleet renewal can change the capacity mix without relying on an increase in the number of vessels owned. In 2025, Seacor Marine Holdings Inc. sold 7 vessels, generating USD 64.6 million in gains. The company described the sold vessels as minimally accretive to its business and used the sale proceeds primarily to fund construction of 2 large platform supply vessels. That approach concentrates capital in a selected service class, so its investment case rests on the replacement vessels’ earning power and delivery timing as well as the returns from disposing of existing ships.
Swire Pacific Limited exited offshore vessel operations when Tidewater Inc. completed its acquisition of Swire Pacific Offshore on April 22, 2022, adding the subsidiary’s 50 vessels to its fleet. Edison Chouest Offshore LLC built and launched the hybrid ECO Liberty on June 28, 2025, for planned support of Equinor’s Empire Wind project in New York. Under 46 CFR 67.19, U.S.-built vessels may be eligible for a coastwise endorsement permitting coastwise trade and towing, subject to documentation, ownership and other restrictions. Acquisition-led fleet expansion and domestic construction thus create different entry routes, with the latter useful when work requires coastwise eligibility. Challengers need a vessel suited to the assignment and an eligible operating structure, making technical capacity alone an incomplete route into restricted work.

Key Opportunities for Market Participants
This comparison examines vessel-charter opportunities requested by Petrobras in Brazil. On October 16, 2026, the company was receiving proposals for 2 PSV classes and a maintenance and safety unit (UMS). Petrobras’s UMS specification describes a unit designed to hold station offshore Brazil while gangway-connected to an installation.
Market Opportunities Table of Offshore Support Vessels Market
| Opportunity | Why now | Buyer / lead segment | Recommended play | Main barrier | Likely beneficiaries |
|---|---|---|---|---|---|
| PSV 3000 charter capacity | Request for at least one PSV 3000 in lots A and B | Petrobras / platform supply services | Structure a charter offer around suitable PSV 3000 tonnage | Securing control of a suitable vessel | Brazilian PSV operators such as Grupo CBO |
| PSV 4500 charter capacity | Request for at least one PSV 4500 in lots A through E | Petrobras / platform supply services | Target the specified vessel class and lot structure | Access to the requested PSV class | Brazilian PSV operators such as Grupo CBO |
| Maintenance and safety support charter | Request to charter a Maintenance and Safety Unit | Petrobras / offshore maintenance support | Pair an appropriate unit with a defined charter-service offer | Obtaining control of an appropriate maintenance and safety unit | Specialized maintenance-support charter operators |
| Source: Mordor Intelligence | |||||
The central opening is a vessel-specific charter offer to an identified offshore buyer. The parallel PSV solicitations allow operators to match their fleet position to a defined class and lot structure. That favors suppliers able to commit the requested tonnage, because an offer dependent on securing a vessel first adds another execution dependency.

Data Sources, Market Sizing, and Validation
Desk Research
Public and official sources such as the U.S. Energy Information Administration's Gulf of America production outlook and the Bureau of Ocean Energy Management's field directory help relate field starts, production, and subsea developments to vessel-service demand. The Global Wind Energy Council's offshore wind report tracks installed capacity and additions that support wind-service requirements. The North Sea Transition Authority's review documents decommissioning timing and cost pressures, while UNCTAD's Review of Maritime Transport 2025 provides global fleet and vessel-age context for supply and renewal checks.
Company annual reports, regulatory filings, investor materials, contract announcements, and reputable maritime and energy press can supplement these public indicators by describing charter revenues, operating days, day rates, fleet utilization, contract duration, and vessel investment. These sources are not exhaustive, and further sources inform collection, validation, and clarification.
Primary Interviews and Surveys
Interviews and structured surveys would include vessel owners and operators, offshore oil and gas and wind customers, decommissioning contractors, and marine-service specialists across APAC, EMEA, and the Americas. Their input would test secondary evidence on charter rates, utilization, operating costs, and vessel assignments, clarify gaps in regional or service coverage, and triangulate assumptions where published fleet or contract data do not resolve a market indicator.
Distribution of primary research fieldwork respondents
| Company type | Respondent position | Region |
|---|---|---|
| Top tier: 36% | CXOs: 20% | APAC: 40% |
| Mid tier: 43% | Functional/Unit leaders: 35% | EMEA: 35% |
| Smaller Players: 21% | Managers: 45% | Americas: 25% |
Market-Sizing & Forecasting
The model starts top down with annual global revenue from offshore vessel charters and operating services, then checks selected totals against sampled vessel-owner roll-ups and charter day rates multiplied by employed vessel days. Offshore oil and gas field start-ups and production, offshore wind installations and operating capacity, decommissioning schedules, active fleet and utilization, charter rates, and newbuild or renewal activity indicate demand, service pricing, and available capacity. Historical evidence is compared across years and regions, while shares are built from the service revenue associated with AHT/AHTSs, PSVs, other vessel classes, oil and gas, wind, decommissioning, other offshore work, and each region. Scenario analysis carries these indicators forward under different project timing, utilization, and rate conditions, with primary respondents checking whether the variable paths reflect practical contracting and deployment patterns. Where a sampled revenue roll-up or day-rate estimate is incomplete, the analyst records the uncovered vessel-days or contract period, tests an alternate rate or utilization range against independent fleet and project evidence, and retains only the supported portion in the cross-check.
Data Validation & Update Cycle
Analysts triangulate owner and operator evidence with independent signals from offshore field activity, wind installations, decommissioning schedules, fleet deployment, and reported contracts, then investigate outliers and reconcile material differences in rates, utilization, timing, and coverage. A second review checks source dates, units, calculations, segment and regional totals, and consistency between the historical base and forecast assumptions. Unresolved anomalies trigger a source check or respondent re-contact before sign-off. The dataset is refreshed annually, updated between cycles when a material project, regulatory, fleet, or market event changes an input, and given a fresh pre-delivery review.
