DNV Fabrication Certified for Lifting Equipment. DNV GL 2.7-1 and 2.7-3 are offshore fabrication certifications specifically for lifting operations while the vessel is stationary or under way.
Fabricators everywhere will take that boost! Offshore metal fabrication and offshore drilling go hand in hand. Let’s get the offshore fabrication market rolling again!

Even with oil prices down, most of the clients we visited at OTC had positive remarks about the show traffic and opportunities. It’s always good to see the heavy fabrication, subsea, and offshore work we do on display at our OEM’s booth. Here’s a great review of the show:
Proud to see our fabricated projects on display at OTC this year. The Offshore Technology Conference in Houston was another technical marvel. Once again – Pushing metal fabrication and design to the limits. They say as much, if not more technology goes into Engineering, Design, Fabrication and Construction for offshore projects as goes into outer space! We believe it! Another great year at OTC!
Looking forward to meeting our customers at the Offshore Technology Conference next week. Excited to see the latest developments in subsea and offshore fabrication. We’re thinking GOM and Mexico will be a hot topic.
We’re winning more and more offshore fabrication for our Mid South Fabrication principal. Right now we have a project in-house for umbilical reel frames to be mounted on drill ships.
Of course weld procedures used on anything fabricated for offshore applications have to be certified by the DNV. Mid South Fabrication is no stranger to developing welding procedures to our client’s welding specifications. We’re a code weld shop for heavy structural welding to AWSD1.1 standards, including ASME and National Code Welding – R, S, U, NB. From pressure vessel and high pressure pipe welding witnessed and certified by Hartford Steam Boiler to the DNV – we work with all classification societies in developing our weld procedures.
For these umbilical reel frames, our EPC client needed us to perform to their own inhouse weld procedure, and witnessed by the DNV.

Det Norske Veritas (DNV) recently merged with the classification society Germanischer Lloyd to form DNV GL. In order to certify to our client’s weld procedure, first we will send the welding and testing specifications to a DNV welding engineer. Once approved, a DNV surveyor will do a site visit to witness the welding of two test coupons, using the exact brand of welding wire, amperage, and speed – as dictated in the client’s weld procedure. Then one of the test coupons will be sent sent to a lab for a secondary DNV surveyor witness on destructive and nondestructive examination and analysis.
