I believe information on FRP internal floating roof can be found in Above Ground Storage Tank Forum or contact enquiries@dynaglass.com.sg.
API 650-H deals with non-metalic types IFR and is being updated by committee.
Looking for members that would like to share successful experience on joining of FRP panels by secondary lamination process.
I believe such joints can be design to be stronger than the panels they join.
Care to comment?
