Subsea 7 is fundamentally a multi-national corporate entity that maintains a dual legal and operational identity, being legally registered and incorporated in Luxembourg while stationing its primary operational headquarters and executive management in London, United Kingdom. The company's business activities, regional subsidiaries, and specialized project teams span multiple continents, reflecting a truly global corporate heritage rather than being tethered exclusively to a single nation's domestic market. Its vessels and engineering offices operate fluidly across international waters and coastal jurisdictions worldwide.
