Barbers Point Harbor, Hawaii, is located on the southwest coastline of Oahu. The present harbor complex consists of an entrance channel, deep-draft harbor, barge basin, and a private resort marina. Current and potential future users of the harbor would like the capability for fully loaded vessels to enter and leave the harbor, but safe vessel draft is restricted by existing harbor and entrance-channel depths. For a vessel to enter and leave the harbor, there must be a safe distance between the bottom of the vessel keel and the ocean bottom (underkeel clearance). The two fully loaded design vessels (modified Bunga Saga Empat bulk -cargo carrier and APL C-9-class containership) used in this study could not enter and leave the now-existing harbor configuration safely. Presently, the State of Hawaii Department of Transportation (HDOT) is using a 0.6-m (2-ft) underkeel clearance criterion in the harbor that translates to a 1.8-m (6-ft) underkeel clearance in the channel. The Corps of Engineers’ Pacific Ocean Division (POD) criterion is more conservative, calling for a 1.2-m (4-ft) and 2.4-m (8-ft) underkeel clearance in the harbor and entrance channel, respectively. Objectives of this study were to determine the optimum vessel draft/entrance-channel depth combinations that can safely transit the entrance channel and harbor. Simulations of the two design vessels’ transit through the entrance channel and into the harbor were made for selected wave conditions, and the underkeel clearance was measured.
