Line Isolation & Inline Weld Testing
Schedule & Asset Friendly Solutions
Traditional isolation procedures for weld testing demand lengthy schedules and unmitigated risks. Numerous blind flanges, skillets, and air movers are required in order to clear the asset of harmful vapors, where even with the use of air movers controlling vapor gases are unpredictable. These risks coupled with project constraints make traditional isolation and weld testing procedures outdated.
Understanding that facility work areas demand schedule and asset friendly solutions, isolation and inline weld testing tools empower fast response, minimize multiple contractors onsite, and deliver proven and safe pipe cavity operations
Inline isolation tools advance safe construction tasks related to welder safety, pressure testing, and weld seam integrity testing. Through the use of patented mechanical functionality, isolation and inline weld testing technology monitors seal integrity and safely vents vapor gases away from the immediate hot work zone. By mechanically performing a double block and bleed upstream of the planned hot work area, a set of compression bolts seal the tool and the internal diameter of the pipe asset. Water and other mediums are then inserted into the annulus of the tool and pressurized to ensure an adequate seal on the desired cavity area. In the duration, pressure is monitored to ensure seal integrity. Once confirmed, vapors are allowed to exit the isolation and inline weld testing tool prior to initiating hot work. This procedure is replicated for weld test integrity, eliminating the need for performing a pressure test on the entire asset.

Project Experiences & Case Studies
GATE Energy provided full commissioning and start-up services for facility offshore Gulf of Mexico. Yard commissioning work completed in South Korea.
GATE Energy provided full commissioning and start-up services for facility offshore Gulf of Mexico. Work performed in Singapore and US. Full commissioning services including systems completion utilizing Omega PIMs. Yard phase commissioning in Singapore.
GATE Energy was responsible for pre-commissioning, commissioning, regulatory testing and vendor management for all Topsides systems of the King’s Quay FPU, both in South Korea and the United States / Gulf of Mexico. Viking, the engineering arm of GATE Energy, was contracted to assist with the development of the topsides standard operating procedures (SOPs).
GATE Energy provided umbilical commissioning planning and execution for subsea tieback to Bullwinkle facility offshore Gulf of Mexico.
GATE Energy provided full commissioning and start-up services offshore Israel. Due to various project engineering and construction delays on the Noble Energy Leviathan project, GATE was tasked with compressing seven months of onshore commissioning into only three months. GATE was able to quickly increase resources and personnel to mitigate a schedule impact and Leviathan topside left the fabrication yard one hundred percent commissioning complete for onshore scope. This greatly reduced the amount of potential offshore carry-over work and facilitated a successful offshore campaign to deliver the facility for initial start-up on time.
GATE Energy provided full commissioning and start-up services for subsea tieback offshore Gulf of Mexico. Provided subsea systems completion and umbilical commissioning planning services for subsea tieback offshore.
GATE Energy provided full commissioning and start-up services for subsea tieback offshore Gulf of Mexico.
GATE Energy provided full commissioning and start-up services offshore Gulf of Mexico. GATE provided full systems completion and commissioning services and played a key role in safely delivering the Delta House FPS and achieving first oil just three years after discovery was made by LLOG Exploration.
GATE Energy provided full commissioning and start-up services for tieback to Tarantula facility in Gulf of Mexico. Provided umbilical commissioning planning and execution for subsea tieback to Tarantula facility offshore.
Commissioning provided offshore commissioning and start-up support for subsea tieback offshore Gulf of Mexico.
GATE Energy provided commissioning services for control system hardware replacement on Constitution facility offshore Gulf of Mexico.
GATE Energy provided full commissioning and start-up services for tieback to Lucius facility offshore Gulf of Mexico. Provided umbilical commissioning planning and execution for subsea tieback to Lucius.
GATE Energy provided full commissioning and start-up services for first ever Amine Unit on a floating facility offshore Gulf of Mexico
GATE Energy provided turnkey full commissioning, systems completion and start-up services for facility offshore GoM. Provided umbilical commissioning planning and execution for facility offshore Gulf of Mexico.
GATE partnered with Anadarko to execute full systems completion and commissioning services on the Lucius and Heidelberg Spars. Anadarko employed a “design one, build two” philosophy in development of these new-build, greenfield facilities. Though the Lucius project was a success in its own right, the extensive implementation of project lessons learned and carry-over of personnel led to GATE safely and successfully delivering the Heidelberg project three months ahead of schedule and significantly under budget.

The traditional way of isolating a flowline, is to install numerous blind and skillet flanges, as well as utilizing air movers, to clear the flowline of harmful vapors. When utilizing air movers, you aren’t always able to control where the vapors go once released to the atmosphere. Wind direction plays a major part in this process.
