International trade, particularly in the intermodal container shipping business, is undergoing significant change as a
result of the Panama Canal expansion. Many shipping lines have announced plans to deploy larger ships which, due to
channel dimension requirements, currently cannot use many U.S. East and Gulf Coast ports.

Performance Advantages
15,000 cubic yards capacity is significantly higher than a
traditional self-propelled hopper dredge enabling the ATB
to be the low cost producer
Required crew complement is significantly reduced
Construction cost is less than a traditional self-propelled
hopper dredge
Reduced insurance premiums
Improved fuel efficiency
Improved operating margins
