Houston, TX DNV Fabrication 2.7-1 & 2.7-3 for Offshore Lifting Equipment

Houston, TX DNV Fabrication 2.7-1 & 2.7-3 for Offshore Lifting Equipment

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.

DNV Umbilical Spools – DNV Lifting Baskets  – DNV Equipment Skids

We can fabricate any structure and any equipment to any DNV specification.

For a Complete “How To” on the DNV fabrication process, please see our explanation here:

Houston Skid Fabrication Capacities

Skid Fabrication Capacity – Houston, Texas

We have the capacity to fabricate many styles of skids – Turnkey. We are only limited by our crane tonnage, hook height and door size. Even then, we can (and have) rented equipment to handle larger fabricated skid projects  with higher weights.

houston skid fabrication capacity capacities

*Please note, that the capacities listed below do not limit us from doing larger skid assemblies. We can handle 30 tons or more by renting a couple of hydraulic lifts and mobile crane to move it around our facility. We’ve done a 96,000 lb. pressure vessels – no problem. We can also source the coating / painting of these large skids that can handle 30T or more.

  • Overhead Hook Height: 28 feet
  • Overhead Crane Tonnages: 20T Crane with (2) 10T hooks plus 10T Crane with (2) 5T hooks
  • Overhead Door Dimensions: 24 x 26H
  • Square Footage Under Roof: 20,000 sq. ft
  • Positioners for Rolling Pipe: 11 all different sizes
  • Sub-Arc Welding Machines: 5
  • TIG Welding Machines: 20
  • Outside Lay Down Space: 2 acres
  • Plate Cutting: Plasma – 20x10x 3/8 Torch – 20x10x4”
  • Plate Bending: 10 foot by 3/8 ths

NDT Capabilities: MT/PT We have a level II certified technician for Mag Particle (MT) and Dye Penetrant (PT) examination in house, and have a third party contractor that can provide a Level III when necessary.

RT/UT/VT We have a third party contractor that provides X-Ray Testing (RT) and Ultrasonic Testing (UT), which includes a level II as a standard with a level III technician when necessary. For visual inspections (VT), we use Certified Welding Inspectors to AWS D1.1, also supplied by a third party.

It’s one thing to be able to fabricate a plain old steel frame for an equipment skid. Any fab shop can do that… It’s a whole other thing to be able to complete a piping system, fabricating the pressure piping and other critical components that are required on a process skid.
It's one thing to be able to fabricate a plain steel frame for an equipment skid manufacturer. Any fab shop can do that... It's a whole other thing to be able to fabricating the pressure piping and other critical components that are required on a Process Skid. Our fabrication principals offer you a turnkey solution with ASME certification stamps R S and U to complete your project, including NACE certification for the final painting and coatingOur fabrication principals offer our OEM manufacturers turnkey solutions for their piping sub-assemblies with ASME certification stamps R S and U to complete your project, including NACE certification for the final painting and coating – and even final delivery with our in-house fleet of 18 wheelers.

We carry over 50 approved welding procedures and the most stringent certifications available for anything from High pressure piping – to DNV and ABS certification. Our ASME code stamps, R Stamp, U Stamp and S Stamp. AWS D1.1  – API 6A … and many other certifications assure our customers of quality and compliance with industry standards.

Our certifications allow you to have a “one stop fabrication shop” who can design, construct, or repair equipment skids containing piping to pressure vessels and other components typically found on OEM manufacturer’s process skids.

From small diameter piping .5″ up to 72″ and High pressure up to 25,000 PSI.

Providing NDE X-Ray and Mag Particle testing.

Drill Pipe For Sale – Grade 22CR 140

Drill Pipe – Corrosion Resistant Alloy Tubing for Sale – High Grade & High-Strength for Demanding Operations

QTY: Approx 32,000 lineal Feet
Condition: New and Bolstered
Size: 3.5″
Weight: 10.2 Pounds Per Lineal Foot.
Grade: (majority) 22CR140 (22CR 140 (some 22CR-130)
Thread: (majority) TENARIS BLUE series – some VAM Top threaded available
CRA (corrosion resistant alloy)

Tenaris Blue Series: Designed for the most challenging E&P operations. Proven extensively in the most complex operating conditions. Design generates stable seal behavior for all combined-load conditions. Coarse pitch thread and steep taper for deep stabbing.

Corrosion Resistant Alloys are needed as well drilling conditions have become more severe. For example: Higher pressures and temperatures, with more sour fields (high hydrogen sulphide content) containing high carbon dioxide levels.
