The Army Corps of Engineers says deepening and widening channels in the harbour will lead to improved vessel navigation, safety, and national economic benefits valued at more than $15m annually.

The project’s operational benefits include more room for the largest tankers and container vessels to transit the harbour and fewer delays related to tidal flows. Deeper, wider channels also reduce the need for large vessels to transfer liquid bulk cargo or containers to smaller vessels before entering the harbour.

Environmental benefits include lower fuel consumption because ships will be able to manoeuvre more efficiently through the harbour. Burning less fuel reduces vessel pollution – emissions of particulate matter, nitrogen oxides and
