Athens Group is your comprehensive service provider for the verification and inspection of all marine, subsea, and drilling equipment.

From Topsides to Subsea, from FEED to obsolescence, and from control systems to electro-mechanical, our consultants apply our systems engineering approach to verification, validation, and inspection services to ensure compliance with the highest standards of safety, performance, and reliability.

Athens Group originated the exploration and production systems verification business in 2002, and was the first company to focus on integrated control systems as a key driver of operational safety and reliability. Since then, we have expanded our services portfolio to become your full-service inspection and verification partner. Our Proven PracticesSM Methodology sets us apart from our competitors and helps ensure your asset is delivered on time, on budget, and remains fit for purpose for the duration of its lifecycle.

    — Engineering Manager, DrillMAX Fleet

  • "There is no doubt that Athens Group helped reduce schedules delays and downtime as a result of the Commissioning work they did. Their consultants were a real asset to our team, making our rig safer and more reliable. They were very professional and knowledgeable, and worked hard to help ensure that our rig would be delivered drill-ready and on-time."
    — Acceptance Manager, Anadarko

  • "I was extremely pleased with the contract language that Athens Group provided. I almost didn’t contact you because we had a short time to get this done, and I thought that there was no way you could deliver on time. But I’m very glad I did contact you … I was expecting the quality but was impressed that you turned things around in 3-4 days; I was afraid it would take months."

    Marathon Oil

  • “I was very pleased with Athens Group’s performance on this project. It was a difficult contract for you all because the scope changed several times and we had to change some of the technicians’ working schedules. I found that you guys documented yourselves very well and were very flexible, which is key in this business. I have recommended you to others.”
    — Mike Montgomery, Drilling Package
    Delivery Manager, BP
