EM&I Featured in Subsea Energy Magazine with Article on Sea Valve Integrity in Offshore Assets

June 27th, 2025

We’re proud to share that EM&I was featured in the latest edition of Subsea Energy Magazine with the technical article “Sea Valves: Do They Matter?” – a clear and insightful piece exploring the critical role of sea valves and how innovative diverless technologies are transforming the way these components are inspected and maintained across offshore assets.

The article highlights how sea valves – often referred to as “intentional holes in the hull” – are essential to offshore operations, supporting vital systems such as cooling, ballast, firefighting, and production.

“Sea valves are present on nearly every marine vessel or offshore unit, from small yachts to massive floating production, storage, drilling and offshore wind units.”

Traditionally, inspecting and repairing sea valves — especially those below the waterline — posed technical and safety challenges. Today, with diverless technologies developed by EM&I, these processes are safer, faster, and more reliable.

The article showcases how EM&I’s ODIN®, PLUG™, and LIMPET systems are redefining sea valve integrity management:

“ODIN ports can be installed during vessel construction or retrofitted during operation, without interrupting production.”

“Multiple successful deployments have shown that the ODIN, PLUG and LIMPET system offers a safer, faster, and simpler method of ensuring sea valve integrity.”

These systems enable close-up visual inspections without divers, provide safe blanking for repairs, and ultimately help ensure asset integrity while supporting continuous offshore operations.

This publication reinforces EM&I’s commitment to technical excellence and leadership in offshore innovation.

  • Tullow Ghana

    We have been largely impressed with the professionalism that characterised the overall delivery of the scope by EM&I and its local partner Stark Energy. The high safety standard exhibited from the onset, with no incident recorded, is highly commendable. The team’s desire to overcome every challenge was remarkable since this was a heavily weather-dependent scope.

  • Vestigo

    I would like to further extend our appreciation to EM&I on the success of FPSO Berantai hull repair works in December 2023, through the application of CLAM technology. This advanced technology application along with the highest level of resources’ expertise and teamwork shown throughout the activity, have resulted in a safe and successful outcome.

  • Shell

    I would like to pay special recognition to the EM&I boys for the pace at which they worked..... all this completed whilst working to the safety standards we demand and in a tank which was physically demanding due to the temperature of surrounding tanks

  • Repsol Sinopec

    This has been a big win from the point of view of safety with NO confined space entry and NO working at heights as well as the added benefit that
    four tanks were completed in just over two days!

  • MODEC

    I would like to thank EM&I for all their work in creating and negotiating the alternative UWILD plan. This is the first MODEC asset globally to have been granted an alternative to the traditional diver driven inspection work.

    The approach taken by EM&I towards Health and Safety has been excellent and they proactively advise on improvements that could be made in this area.

All in all it has been a productive visit and I have no hesitation in having the EM&I team back on board in the future.

  • Vantage

    Your excellent professional organization and great work results in the successful completion of this scope with the minimum down-time for the rig. Overall I was very impressed and couldn’t recommend your company highly enough to anybody who would ask.
