The U.S. Army Corps of Engineers, Honolulu District has commenced maintenance dredging of the Honolulu Harbor, located on the southern coast of the Island of Oahu.
Honolulu Harbor is the principal seaport of the State of Hawai‘i, receiving more than 98% of all goods through its harbors. Much of the containerized items are first shipped into Honolulu Harbor, then separated and trans-shipped to the neighbor islands.
Dredging of the harbor has been split into 3 different phases due to funding and agency coordination. Prior phases were completed in 2022 and 2016, where dredging was done in other areas of the harbor. Current dredging action is expected to take approximately a month.
This is the third maintenance dredging project that the Corps has undertaken this year in Hawai‘i. Maintenance dredging at Kaunakakai Harbor, located on the south-central coast of the island of Moloka‘i, and Kahului Harbor, located on the northern coast of the island of Maui, were previously completed on April 30 and June 7, 2024, respectively.
Approximately 28,000 cubic yards of sediment were removed from Kaunakakai Harbor, and approximately 142,000 cubic yards were removed from Kahului Harbor, so vessels could safely enter, exit, and maneuver within the harbors.
