2. A Pilots Perspective: Truth and Consequences Truth: Mississippi River channel maintenance dredging is reduced Truth: Mississippi River channel maintenance dredging is reduced Consequences: Consequences: 1. Reduced safe passing distances for ships 2. Reduced channel creates navigation hazards 3. A reduced channel equals cargo losses 6/13/2016Associated Branch Pilots for the Port of New Orleans 2

12. Lost Channel Depth Equals Lost Drafts and Lost Cargo for the Mississippi River Panamax bulk carriers lose on average 179 tons of cargo per inch of lost draft. Panamax bulk carriers lose on average 179 tons of cargo per inch of lost draft. Thus a foot of lost channel depth is equal to a loss of 2,148 tons of cargo. Thus a foot of lost channel depth is equal to a loss of 2,148 tons of cargo. Considering the recent 5 foot draft reduction due to shoaling, a typical Panamax bulk carrier would lose 10,740 tons of cargo per trip.
