This project consisted of the replacement of 10 bollards at NNS Pier 3. Nine 30-ton bollards were removed from a moored spud barge and replaced with new welded 40-ton bollards. Additional work included the replacement of one 50-ton bollard and dolphin repairs. The repairs included removal of existing hardware, core drilling and installing new hardware, epoxy crack injection on all sides of the mooring dolphin, and pouring a new grout bed for the installation of the new 50 ton bollard.
