HANG-OFF SEALING CASE
The VPI Hang-Off Sealing Case is an innovative way that VPI have developed to seal existing hang-off systems. VPI were approached as there were a number of existing hang-off systems that were unsealed/poorly installed and needed to be sealed.
The importance of a hang-off system to be sealed is critical as toxic gases, such as hydrogen sulphide, are formed due to the cathodic corrosion protection of the monopile which poses a health and safety risk to potential work crews on the cable decks. VPI engineered the VPI HSC to tackle this challenge and since has been deployed globally as an engineered solution.
Using a retrofit split piece polyurethane casing design, the VPI HSC encapsulates around an existing hang-off system. Once the VPI HSC has been secured around the existing hang-off system, it is then filled up with the resin to become airtight.
