Methane Barrier, Hawaiian Electric Company
Hawaii · 2009
The installation
A 600,000 SF biogas cover and passive methane barrier installed over an existing lagoon in multiple phases, coordinated across simultaneous contractor crews. The installation included over 150 penetrations through the liner. All seams were vacuum tested and the installation was smoke tested for a leak-proof system.
Planning a similar installation
Include the site location, approved mitigation plans, specified membrane, penetration details, inspection requirements, and slab schedule.
Agree on the field testing and closeout records before mobilization. ECA's documented QA/QC program includes panel layout maps, seam records, test results, and field logs.
