Customer: West Texas Fabrication Shop
Asset Type
Piping for New CP2 LNG Terminal
Machining Location
Fabrication Shop, West Texas USA
Date
June 2026
Scope
Field machining 200 piping spools, including severing to length and adding compound weld preps
Key Requirements
Meeting the tight schedule, high repeatability, weldâready accuracy across diverse spool sizes
Items
Heavy Wall Piping from 8" to 72â diameters. Wall thicknesses up to 3.75â
Materials
High-grade alloy steel for critical LNG use
Equipment Used
HD, MS and NB Clamshells
The customer contacted Hydratight to machine more than 200 spools in the field, including severing them to size and applying compound weld preps. The project was delivered to a tight schedule for a fabrication shop supporting the construction of Venture Globalâs new CP2 LNG terminal in Louisiana.
Tight Fabrication Schedule
The client needed machining work on more than 200 spools quickly to keep LNG plant fabrication on track.
Heavy-Wall Alloy Piping
The work involved large-diameter, high-grade piping with wall thicknesses up to 3.75 inches.
Precise Weld Preparation
Each spool needed accurate severing and compound weld preps to support fit-up and weld quality.
High Project Risk
Any delay or rework could have affected downstream construction on the CP2 export terminal.
Hydratight mobilized to the site, bringing a full package of clamshell machines, tooling, and technically qualified personnel to execute the work safely and repeatably.
HD (heavyâduty), MS (midâsize), and NB (narrowâbody) clamshells were deployed to cover the full range of spool sizes and geometries required by the fabrication shop.
Reliable OEM Clamshells for HeavyâWall Piping
Hydratight deployed HD, MS and NB clamshells to match diameters and wall thicknesses, delivering stable mounting, controlled cuts and repeatable compound weld preps for LNG piping spools.
Qualified Field Machining Technicians On Site
Technically trained Hydratight personnel set up and operated all clamshell machining, ensuring safe procedures, correct parameters and consistent results across more than 200 fabrication spools.
Full Tooling and Spares for Continuous Work
Arrived with required tooling, consumables and spares, reducing downtime and enabling continuous machining to keep aligned with CP2 construction milestones.
Integrated Severing and Weld Prep Workflow
Each spool was severed to exact length, then machined with specified compound weld preps, combining operations into one controlled sequence to minimise handling time and total machining duration.
Hydratightâs controlled severing, precise compound weld preps and continuous onâsite support delivered consistent results across more than 200 heavyâwall spools. This helped ensure schedule adherence, weld integrity and the clientâs confidence in Hydratight when supporting future CP2 fabrication phases. As the client put it, âYour team met our needs proactively and were a pleasure to work with â you were on time and on budget.â The key outcomes from the campaign are highlighted in the results below.
Rapid, consistent, and accurate machining produced weldâready spools, keeping the fabrication shop on schedule and ensuring welding teams always had correctly prepared piping sections available.
Accurate cuts and precise compound preps delivered uniform fitâup and alignment, supporting weld integrity requirements for highâgrade alloy piping in the CP2 LNG export terminal.
Reliable machining reduced dimensional errors and avoided rework, helping protect the overall fabrication timeline and downstream construction activities.
The client selected Hydratight for the next fabrication phase, recognising the combination of schedule adherence, machining quality and professional onâsite support delivered during the initial project.
