The Howland Hook Marine Terminal operated by the New York Container Terminal (NYCT) on New York Harbor is being modernized for the next generation of Post-Panamax container ships, which requires deeper water and larger container cranes. The terminal location is shown in figure 1. The NYCT is upgrading its wharf in combination with the Army Corps of Engineers dredging project to deepen the main shipping channels in New York Harbor, thereby permitting larger vessels to enter the ports. Underwater rock blasting was required along approach waterways in the Arthur Kill and at berth 3 to allow passage of deeper draft ships. Berth 3 comprises four reinforced concrete deck sections connected with pile caps to 24-inch (610 mm) and 36-inch (914 mm) diameter concrete-filled steel pipe piles to support four large container handling gantry cranes.
