Ocean Cargo Barge Solutions

McDonough’s oversized open ocean barges are designed for the transportation of cargo in open sea states. The deck barges provide advantages with open deck space for oversized cargo, as well as shallow port access.

ABS Ocean Barges

These over sized open ocean barges are built to the requirements set by the U.S. Coast Guard and the American Bureau of Shipping (ABS), as the building Class Society. The Class Society is charged with vessel inspection, construction parameters, and verification of standards. The corresponding Class Society documents are required to be carried on board the vessel at all times.

 

Built for Safety and Efficiency

Our fleet of oceangoing barges is classified by the American Bureau of Shipping classification, A-1, Maltese Cross for all-oceans service. Most of these barges have recessed deck fittings which allow unobstructed deck utilization, except for towing padeyes, emergency towing padeye, chocks, and light standards.

Typically, these oceangoing deck barges feature:

  • Shaped Bows & Reinforced Compartments: For superior hydrodynamics and structural integrity.
  • Stern Skegs: To ensure directional stability while under tow.
  • Anti-Fouling Bottom Paint: To maintain fuel efficiency and hull health.
  • Heavy-Duty Protection: Steel rubrails and wooden timber fenders to safeguard the vessel during complex maneuvers.

Project Cargo Capable Ocean Barges

Our ocean barges are the preferred choice for project cargo. We specialize in the transport of massive, high-value components that require precision handling and deck strength.
From offshore wind turbine components and heavy industrial machinery to bridge sections, our oceangoing fleet is engineered to handle concentrated loads. With high deck load ratings and expansive, unobstructed surface areas, we bridge the gap with seamless offshore transportation logistics.

*some of these barges have spudwells.

Spud Barges

Drop Spud Barges can be specially built to support a working crane. This type of barge typically has a boxed stern that provides maximum flotation while operating a crane. Extra strengthening is generally provided under the crane working area by use of additional bulkheads, internal trusses, or deck frames.
