Recently Tension Leg Platform (TLP) Technology has been applied in developing deep water-oil/gas wells. Shell Offshore installed a record-setting TLP in the Gulf of Mexico in the Auger Field. As corrosion protection for the TLP tendon pipes, a three-layer polyethylene coating system, consisting of thermosetting liquid epoxy primer with chromate pre-treatment, modified polyethylene adhesive and polyethylene layers, was applied for the first time because of its good performance and economy. This paper describes an investigation into the effects of chromate treatment and liquid epoxy primer on adhesive durability. The results for actual tendon pipe coating are also introduced.
