Offshore Industry Statistics

Offshore Industry is moving fast in 2024 and the buildout is no longer just drilling and wind farms but the grid, subsea systems, and downtime performance that make projects bankable.

Offshore Industry output keeps moving, and the scale is anything but subtle. Offshore oil and gas production on the US OCS hit 3.1 million barrels per day of oil equivalent in 2024, while the offshore wind buildout is already chasing next year’s grid constraints with more than 20 GW in the UK connection queue by end 2023. From subsea cable length to decommissioning pipelines, these statistics reveal how far offshore capabilities extend and where bottlenecks are forming.
