OEG Offshore

What OEG Offshore does

OEG is an Aberdeen-headquartered global energy solutions provider that has served the offshore energy industry since 1973, operating what it describes as the world's largest fleet of DNV-certified offshore cargo carrying units (CCUs) with more than 80,000 assets deployed worldwide. The company supplies mission-critical infrastructure and integrated services to major offshore energy operators across 65+ countries on six continents, with reported involvement in approximately 97% of global offshore wind farms. Its core offerings span offshore equipment (CCUs, waste handling units, tanks, modules, and well completion solutions), subsea services (cable services, inspection repair and maintenance, UXO clearance, excavation, and commercial diving), wind farm services (balance of plant, blade services, high voltage, temporary power, WTG services), vessel services, fabrication, aviation refuelling systems, and accredited workforce training (GWO, IRATA, ICATS, and OPITO-approved programmes).

Revenue is generated primarily through recurring equipment rental of CCUs and related hardware, supplemented by professional services contracts for subsea and wind farm work, training fees, and hardware sales. The go-to-market is enterprise field sales, with OEG establishing direct relationships with major energy operators and winning multi-year contract anchors such as the Bass Strait extension through 2036. The business model is asset-heavy, supported by a $140 million debt facility raised in October 2023 (with participation from Santander, Citi, Goldman Sachs, and NatWest) earmarked for renewables expansion and M&A.

Recent strategic activity includes acquisitions of Seajet Systems (February 2023), BlueManta in Brazil, and Hybrid Resource Management (June 2026), plus the launch of GEOBASE, an industry-first vessel dimensional control assurance software platform (April 2025). The company is led by CEO John Heiton and maintains a regional office network spanning the UK (Aberdeen headquarters and Fareham), Australia (Barry Beach manufacturing), Qatar (via the VGE joint venture with Al Nasr Holding), Brazil, Japan, and Poland, serving a customer base that includes Vestas, Baltic Power, and Woodside.
