  • Abstract:
    Fiber reinforced polymer (FRP) composite piles were used on a pier rehabilitation project at ; Little Diamond Island in Casco Bay near Portland Maine. The project was the replacement ; of an aging wooden pier at the ferry berthing terminal. The FRP piles were installed as ; fender piles, designed to absorb the kinetic energy of vessels docking at the pier, to prevent ; damage to vessels and to provide an abrasion resistant surface. The FRP piles were 11.25 ; inch diameter, 5 ply, hollow piles, having similar properties to wooden piles. The piles also ; have a heavy duty abrasion resistant sleeve, 0.75 inch thick. There were no significant ; problems during construction of this project. Using the FRP composite piles required a re-design of the bolting configuration, due in part to the fact that counter-sinking for bolt ; heads is limited on the hollow FRP composite piles. Despite the increased cost of this ; installation, the project furthered the Department’s understanding of the requirements of ; using composite piles. In addition, the project will provide an opportunity to observe the ; performance of composite piles compared to wooden piles.
