Can You Remove A Resin Type Hang-Off After The Resin Has Cured?
After discovering damage to a power cable or identifying that it has reached the end of its operational life, it may require removing Resin Type Hang-Off before the cable can be replaced. The question is, is Resin Type Hang-Off Removal possible after the resin has cured, without offshore expenses and time consumption becoming extreme? The following Resin Type Hang-Off Removal case studies explore the complexities of removal from a LV MV HV offshore marine cable and why Resin Free Hang-Off (RFHO) solutions by Kintech Energy are essential to avoid these barriers in future projects.
Resin Type Hang-Off Removal Case Studies
Case Study #1
Several cables had to be removed and replaced shortly after installation, but the problem was discovered after the resin in the hang-off had cured. A dive team were mobilised to cut the cable at the exit of the CPS, then the entire hang-off was detached from the TP flange and lifted.
The cable and hang-off had to be held in position above the TP flange and the power cable, cut into short sections to be removed. Due to resin contamination, none of the parts could be re-used. The operation required many teams of offshore personnel, including dive spread and the supporting vessels, as well as associated sub-contractors working around the clock. The cost of the removal operations resulted in millions in costs.
Case Study #2
A damaged power cable needed to be removed to allow for a new cable installation, with the existing power cable being secured by a Resin Type Hang-Off. Using a range of power tools, the offshore teams worked on one Resin Type Hang-Off Removal for several days, working 8 hour shifts to complete the job.
Resin Type Hang-Off Removal Solution/Alternatives
The Subsea Cable Hang-Off Systems supplied by Kintech Energy are free from harmful resin and the removal process is the reverse of the installation process, ultimately removing any reliance on using marine grade resins to maintain an airtight seal. Holding a demonstrable track record, the Kintech Resin Free Hang-Off has been installed in Offshore Windfarms around the UK and Europe on 33kV and 66kV subsea power cables.
Hassle free power cable removal with no Resin Type Hang-Off Removal, allows for cable repair or parts of the hang-off to be re-used or recycled, which eliminates disposal issues when dealing with contaminated parts by the cured resin.
The Kintech Resin Free Hang-Off (RFHO) protects the health and well-being of the cable installation teams, reduces the inevitability of substantial costs and time consumption, and can be easily recycled (or re-used).
