IK-Group has developed a solution to stop the leakage on the 6”- 45deg elbow on Bonga WT-04 template.

The 6” Bend Split Clamp was designed to be installed by ROV while the pipeline was depressurised (Isolation Valve closed) during the installation.
Due to insufficient space for installation, a diamond wire cutter tool was designed and built for purpose.
Upon successful modification and installation, a retrofit beam was installed to reinforce the structure and restore its original function.

  • Design Pressure: 245 bar
  • Water Depth: 1000m
  • Pipe OD: 6" (168,3mm)
  • Design Life: 20 years

"Super-fast, flawless execution, and high quality performance both from the office and offshore teams."
