The Resin Free Hang-Off

Making installation safer, faster and less complex

Kintech Energy’s pioneering and proven Resin Free Hang-Off solution is transforming subsea cable installation

This new generation hang-off eliminates the need to use marine grade resins to maintain an airtight seal across the interfacing platform within an offshore transition structure or offshore substation. 

By removing the challenges encountered by cable installation contractors when storing, transporting, preparing, applying and disposing of resin, we’re making installation safer for offshore teams, safer for marine life and the environment and far more efficient.

Created in the UK, deployed internationally

Decades of subsea cable engineering expertise have shaped the world-leading Kintech Resin Free Hang-Off.  

Our team have faced the challenges experienced by the offshore energy sector. The Kintech Resin Free Hang-Off system was born from this, demonstrating our passion for creating innovative solutions for subsea cable manufacturers, installers and developers.  

Our product is designed, manufactured and tested in the UK, and is used on major projects… and by global energy sector leaders.

Eliminating resin use, saving resources

Up to 32 litres of resin can be required to provide an airtight seal

2 people required for 40 minutes to plug and seal potential leak paths, before resin applied

3800 litres of resin required for windfarm with 60 WTG, based on 32 litres of resin per hang-off*

*Assuming 2 hang-offs at each wind turbine

120 hours required for windfarm with 60 wind turbines*

*Assuming 2 hang-offs at each wind turbine

Resin requirements eliminated with Kintech Resin Free Hang-Off

Leaking hang-off can lead to extensive and expensive clean-up operations adding more visits to offshore assets and increasing vessel time

Resources and time saved with Kintech Resin Free Hang-off

Digital integration of the Resin Free Hang-Off

Kintech has integrated a digital platform to manage all critical data and documents via a unique QR coded label, applied to every Resin Free Hang-Off.  

The QR code enables access to drawings, procedures, checklists and traceability information. This is an industry first for subsea power cable hang-off supply, ensuring confidence in the product through the manufacturing process and operations and maintenance.  

The QR code acts as a digital passport for each hang-off, providing end users with instant access to a full history of the asset.

Operational Time of the Resin-Free Hang Off

Why use the Resin Free Hang-Off?

  • Has been specifically designed and developed to remove any reliance on using marine grade resins to maintain an air tight seal.
  • Can be designed to fit a range of interfacing flange sizes in a mono-pile or jacket type foundation as well as Substation J-tubes.
  • Has passed a stringent test program for pressure withstand and tensile capabilities.
  • Addresses important HSE issues by removing the resin.
  • Reduces installation time and provides a hang-off which can be easily removed and re-used, providing flexibility during installation should the need arise to remove the hang-off.
  • Eliminates future disposal problems associated with resin type hang-offs.
  • Metal parts (with the exception of the temporary clamp) are galvanised to BS EN ISO 1461 and can be reused.
  • Parts (including the gaskets) can be assembled around the pulled-in cable eliminating the requirement to attend the tower prior to cable installation to install hang-off parts. This reduces the number of visits required by tower teams during cable installation.
  • Includes two earth bonding points to connect the metallic RFHO with the local earthing system.
  • Features a unique design incorporating flanges and gaskets in combination with an upper sealing system to provide a pressure resistant seal across the air tight platform.
