This study assessed the viability of efforts to move the Naha Military Port (NMP) from its current location in Naha, Okinawa, Japan, to a new location. This planning effort focused on reviewing and analyzing prior planning, validating Naha Military Port Replacement Facility (NMPRF) requirements, evaluating alternatives, obtaining stakeholder input, and developing a preferred alternative for relocation of the NMP. The resulting plan supports ongoing bilateral agreements between the U.S. Government and the Government of Japan.

​

Key components of the study included:

​

• A stakeholder-driven planning process consisting of interviews, a pre-planning workshop, and an intensive on-site planning workshop. Stakeholders included U.S. Forces Japan (USFJ), U.S. Army Japan (USAJ), Military Sealift Command Okinawa, Marine Forces Pacific, and other port users.

• An assessment and validation of military port operation and facility requirements, port development factors, and project risks.

• A planning-level analysis of explosives safety related to ammunition operations at the pier. Our team created a planning-level Inhabited Building Distance (IBD) ESQD arc based on the operational capability requirement for the NMP Replacement Facility to provide berthing for a ship laden with up to a specified Net Explosive Weight (NEW) of ammunition and associated operational capability, including shipboard training venues, periodic equipment maintenance, and reconfiguration of ship loads.
