What OEG Energy Group does
OEG Energy Group is a privately held Aberdeen-based offshore energy solutions provider that traces its roots to 1973 and operates under ultimate parent Starship TopCo Limited. The company delivers mission-critical infrastructure assets, technologies, and services across the offshore energy value chain to oil and gas operators, offshore wind developers, and other major energy customers.
Its core offering is organized into specialist divisions. The Offshore Equipment division operates what the company claims is the world's largest fleet of DNV-certified Cargo Carrying Units (CCUs) — a fleet the company states exceeds 80,000 assets — alongside waste handling units, tanks (including cryogenic and Jet-A1 fuel), modules, and well completion solutions. Subsea Services covers cable services, inspection/repair/maintenance (IRM), site clearance and UXO, subsea excavation, and commercial diving, deployed using proprietary assets including the Subsea Multi-Tool (SMT) ROV. Wind Farm Services span balance of plant, blade services, high voltage, marine coordination, WTG services, and bespoke temporary power solutions built around Stage V emissions-compliant generators for turbine commissioning. Supporting lines include Vessel Operations (crew transfer and subsea support vessels with statutory inspection), Aviation Services (OPITO-approved helifuel systems and training), OEG Training (GWO, IRATA, ICATS accredited courses), and Fabrication. Sub-brands include BlueManta in Brazil.
Commercially, OEG operates an enterprise field-sales model with direct account engagement of large energy customers, generating revenue from equipment rental (framed as recurring subscription-style), project-based integrated services (one-time contracts), managed vessel operations, and professional training services. Pricing is quote-based and not publicly disclosed. The company reports approximately 1,500 personnel, operations in 65+ countries across six continents, and hub locations in all main energy provinces. Recent strategic activity includes acquisitions of Trinity Rental Services (July 2025) and Hybrid Resource Management (June 2026), a new Solent-region office in Fareham (April 2026), and a six-year Brazilian offshore chemical tanks contract (June 2026).
