Hot Tapping

Client Requirement 

The client wanted to reroute their existing Aviation Turbine Fuel Pipeline (ATF) and create a branch connection, as their old tank farms were being removed and replaced with new ones.

Challenges Faced

Challenges Faced

There were several challenges faced during the execution of the project, such as delay in obtaining permits as the project location was a high-security area. The COVID-19 pandemic also caused delays due to restrictions. We also had to proceed with extra caution due to cyclones affecting the project location. The Wellube team tackled all the challenges with proactive planning and preparation to ensure smooth execution.

Unique Solution Delivered 

Our team did a site survey to understand the client’s requirements and the site conditions. This helped us discuss their expectations and create a customized project execution plan. The overall scope of the project included one 10” and 20” hot tap each, two 10” double position line stops and four 20” double position line stops.

The Wellube team worked on the project from end to end. Our design and engineering team worked on manufacturing the extruded type of hot tap and line stop fittings based on the dimensions of the pipeline in order to avoid extra weld joints on the fittings.
