What Oceanscan does

Oceanscan is a UK-headquartered (Aberdeen) provider of subsea and non-destructive testing (NDT) equipment, calibration services, and specialist offshore personnel to the offshore energy, renewables, defense, petrochemical, and marine survey industries. Founded in 1989, the company operates a fleet of 4,000+ rental assets and supports 4,700+ rental projects and 1,500+ calibrations per year, with a portfolio spanning hydrographic survey sensors (acoustic positioning, multibeam systems, sonars, bathymetry systems), ROV tooling, ultrasonic and eddy current NDT equipment, and ISO/UKAS-accredited calibration services executed through five precision subsea calibration tanks at its new Dyce, Aberdeen facility opened in May 2026.

The company monetizes through a mix of equipment rentals (the largest stream), ISO-certified subsea and NDT calibration services, specialist personnel placement (ROV pilots, surveyors, inspection engineers, diving technicians), marine geotechnical services (via Geoforce Technical Services), and consumables/hardware sales, all priced on a quote basis typically via multi-year contracts with enterprise customers. Go-to-market is sales-led, with technical sales teams running direct engagements supported by regional offices in Aberdeen (HQ), Houston (US), and Singapore (APAC) plus sub-brand locations for Sercal (NDT calibration, Cannock), Geoforce (geotechnical, Suffolk), and HPR (personnel, Aberdeen/Lowestoft).

Oceanscan operates as a subsidiary of Venterra Group following its 2025 acquisition, leveraging the parent's portfolio for cross-sell with INSPIRE Environmental and HPR while retaining standalone branding under the Oceanscan Group. The company employs 101-250 staff globally (57 in Aberdeen as of May 2026) and has stated its subsea business doubled in size across Europe over the past year, supporting a current trajectory of capacity expansion and product line extension into dedicated subsea calibration services.
