A practical guide for marine suppliers looking to enter or grow in the offshore energy market — covering procurement processes, certifications, capability statements and relationship building.

Understanding the procurement landscape

  • Major operators (BP, Shell, Harbour Energy, Equinor, Ocean Winds) use structured procurement systems with pre-qualification requirements.
  • Tier 1 contractors (Subsea 7, TechnipFMC, Petrofac, Wood Group) often manage subcontracting for large projects.
  • The Supply Chain Charter and Fair Work commitments increasingly influence who gets work — demonstrating local content and fair employment practices matters.
  • Registration on supplier databases (e.g., Achilles, FPAL, JQS) is often a prerequisite for tendering.

Certifications and capabilities that matter

  • ISO 9001 (quality management), ISO 14001 (environmental) and ISO 45001 (health and safety) are commonly required.
  • Industry-specific certifications: DNV, Lloyd's Register, or Bureau Veritas type approvals for equipment.
  • Cyber Essentials certification is increasingly required, particularly for suppliers handling operational data.
  • A clear capability statement — one page, evidence-led, with case studies — is more effective than a glossy brochure.

  • Attend industry events: Offshore Europe, All-Energy, SPE conferences and regional supplier forums.
  • Engage with trade bodies: OEUK, RenewableUK, Scottish Renewables, IMCA, Energy Institute.
  • Start with smaller contracts and build a track record. References and case studies from completed work are your most valuable asset.
  • Be patient. Procurement cycles in offshore energy can take 12-18 months from initial contact to contract award.
