Vessel Supply & Demand

Offshore Wind Survey Vessels (Supply & Demand)

This study provides a detailed, global analysis of the offshore wind survey vessel market. Key supply trends are examined by vessel category (Geotech with drilling tower and CPT, geophysical, and USV/ASV), highlighting the main players and operational regions. The market is contextualized with historical demand data (2016 - 2024), with a 12.3% CAGR while detailed forecasts give the outlook through 2040. 

Fleet utilization analysis underscores near-term constraints for geotechnical survey vessels and long-term pressures on versatile survey assets. The report, which uses Spinergie’s continually updated Market Intelligence data, also addresses newbuild versus conversion dynamics, demand by kilometers of cables, and methodological assumptions. A customized study is available on request for focus points such as regions or countries.

Demand-supply confrontation and gap analysis

The Offshore Wind survey market is growing steadily with a CAGR of 12.3%

Geotechnical assets experienced a growth of 66% in vessel days over 5 years. The outlier is USVs, which rose from zero activity five years ago to ~2000 days in 2024

Over a hundered active Geophysical Survey assets

Excluding USVs and vessels featuring CPT or drilling equipment, the largest ship owner is GEOxyz, which has a versatile fleet of vessels ranging from 7m to 80m. Fugro leads in Geotechnical vessels.

Too many projects, too fast

Short-term demand from projects in the permitting and pre-engineering phases would result in doubling activity for survey vessels.

From projects entering construction and reaching COD, inspection surveys are on track for steady and robust growth.
