Metal Trades U.S. Navy Contract for DH Barges

Metal Trades, Inc. was con- tracted by Maybank Industries

LLC to build two new types of double hull barges for the U.S.

Navy. Three YON fuel barges and one Ship Waste

Offloading Barge (SWOB) will be built, each type with identical 6,900 barrel capacity cargo and double hull configu- rations. The ABS classed barges are being designed by

Bristol Harbor Group of Bristol, R.I. Production engineering services are being performed by Bluewater Designs,

Inc. of Delray Beach, Fla. This is the second time that Metal Trades, Maybank Industries and Bristol Harbor have teamed up to design and build a new type of double hull barge for the U.S. Navy meeting the latest operational requirements with full compliance with the Oil Pollution Act of 1990. Compared to the previous contract that built two 14,000 barrel fuel barges for the U.S. Navy, this contract addresses two new requirements — a more compact fuel barge design for space-constrained facilities and also a new type of double hull barge to offload and dispose of waste oil from naval vessels.

U.S. Barge Delivers

Double-Hull Barge

U.S. Barge recently delivered anoth- er petroleum barge to Harley Marine

Services. The Barge Anne Elizabeth, designed by Elliott Bay Design

Group, was christened on October 4, 2010 by her namesake, Anne

Elizabeth Hall. The double-hulled barge is OPA 90-compliant, with vapor collection piping and has two isolated cargo systems. The main cargo is intended to be fuel oil and the auxiliary system will handle marine gas oil (MGO). All outfitting was completed in-house by U.S.

Barge. Barge Anne Elizabeth is outfit- ted with a 65-ft, fixed boom and an 11 ton hydraulic crane with main and auxiliary winches. Hydraulic power is provided by twin pressure-compen- sated pumps with electronic clutches.

The barge contains a monitoring sys- tem with tank sensors and alarms and a vapor control system. This new addition to Harley Marine Services’ fleet carries on their longstanding tra- dition of naming barges for heroes in the fight against cystic fibrosis. Anne

Elizabeth Hall was born in 1997 and, shortly thereafter, was diagnosed with cystic fibrosis. She is currently a visi- ble leader in the fight to raise aware- ness and develop new treatments for the disease.
