Legasea

Legasea is a subsea equipment specialist based in Aberdeenshire, Scotland, whose business is built around circular economy solutions for the energy industry. It presents what it calls complete shore-to-store subsea services, covering the whole lifecycle of subsea equipment from deployment and operation through decommissioning and reuse, and it operates under SEPA Waste Management License WML/L/1195912. The technical side of the business rests on electrical, mechanical and hydraulic engineering. Its certified technicians carry out subsea connector refurbishment, hydraulic coupling manufacturing, cable testing to IPC/J-STD-001 standards and umbilical testing. The facilities behind that work include 75-tonne overhead cranes, 60,000psi hydro testing capability and clean rooms used for Factory Acceptance Tests and Site Integration Tests. Published case studies cover site integration testing, casing tool refurbishment and testing, interface testing, umbilical testing and flushing, skid modification, and electrical and umbilical terminations. Equipment management is a second strand. Legasea refurbishes Subsea Christmas Trees, Wellhead equipment, Control Pods, Hydraulic Power Units and specialist tooling, using ultrasonic cleaning and reverse engineering to restore components to as-new condition and extend asset life instead of replacing hardware outright. The circular economy work is what the company treats as its distinguishing activity. It takes complete ownership and liability for recovered subsea production systems, makes them safe and clean, and disassembles them to component parts. Reusable components are then held to fulfil urgent spare requirements when critical production is at risk, which the company positions against the expense and lead times of buying new from original equipment manufacturers. Since 2018 it says it has managed over sixty decommissioned subsea production systems, and it quantifies the environmental effect as approximately 82.4 tonnes of CO2 emissions prevented per reused subsea tree, with potential carbon reductions of up to 70,000 tonnes across UK North Sea installations. Around that core, Legasea provides marine growth removal, material segregation, secure storage and preservation, and waste management aligned with circular economy principles. It also offers early consultation from conceptual studies through FEED studies, so operators can plan interconnected infrastructure projects in advance. Its customers are oil and gas operators, and it frames the value of reuse in terms of Corporate Social Responsibility, government sustainability strategies, risk mitigation, cost reduction and productivity. Legasea Ltd is registered in Scotland with company number SC617131 and works from Unit 11 Birchmoss Plant and Storage at Echt, Westhill, Aberdeenshire. It also publishes a QHSE policy and figures on carbon savings and environmental impact, plus a record of accreditations and awards.
