EM&I’s New Diverless Sea Chest Blanking Plate Technology Deployed At Equatorial Guinea

February 22nd, 2022

Diverless Sea Chest Blanking

EM&I has proven a diverless sea chest blanking method using an ‘intelligent’ motorised wire guided blanking plate.

The device and technology is called LIMPET™ and has been used successfully for a major lease company offshore in Equatorial Guinea.

The JIP (Joint Industry Project) for HITS (Hull Inspection Techniques & Strategy) has encouraged industry to find safer and more efficient methods for subsea activities associated with Floating Assets.

The LIMPET Sea chest isolation system can be deployed from the asset. The LIMPET blank locates itself onto the sea chest inlet using the ODIN® Sea Chest Locating system. This is controlled from the main deck and an ROV is used to attach the locating system and to provide a ‘set of eyes’ to assist with guiding the LIMPET blank into position on the sea chest inlet. LIMPET does not require any diving support, eliminating the inherent risks of diving operations and reducing POB (Persons on Board), operational downtime and cost.

“LIMPET is an extension of our ODIN service line which ranges from UWILDs to valve and side shell repairs. The next few months will see further applications including much lower cost deep water mooring and seabed surveys” said Danny Constantinis (Executive Chairman & CEO) of the EM&I Group.

  • 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.

  • Ocean Rig

    Congratulations with your job well done and safely. It’s been a pleasure having you guys on board. I have to report that I really appreciate working with your team here on board, their positive and professional attitude was greatly appreciated

  • BW Offshore

    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. Having a trusted expert in this field who could highlight any areas of concern and make the required recommendations was of immense value to the operations. 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.

  • ExxonMobil

    EM&I have been able to provide skilled, specialist personnel during every mobilisation, and in all cases, they have been outstanding. The work has been professionally done and the reporting of the highest quality. I would like to pass on my appreciation to everyone in EM&I involved in the job for their hard work and making the job very successful.

  • SBM Offshore

    This Project required exceptional vigilance in keeping personnel safe, EM&I did a very good job in a safe manner. They maintained high safety awareness and gave full cooperation among the ASOM team. This Project can be summarised in 4 words … preparation, verification, execution, documentation. EM&I scored top marks in all categories.

  • Pacific Drilling

    The use of proper planning and risk assessments by EM&I was very important and critical to their projected timeline as all EM&I UWILD inspections were performed during normal offshore drilling operations. All inspections and documentation performed to the satisfaction of the Class Society Surveyor.
