Crowley Maritime Corp. Orders Two 580-Foot Triple-Deck Barges

Crowley Maritime Corporation has ordered construction of two 580-foot, triple-deck barges for service in its Caribbean Division, according to a recent announcement by Leo L. Collar, president of Crowley's Offshore Group, SQ.n Francisco, Calif.

These vessels will be the largest roll-on/roll-off barges in the world, measuring 580 feet by 105 feet by 56 feet. Each barge will have a capacity of 380 forty-foot trailers.

Both barges will join five other 400-foot by 100-foot, double-deck barges already in service for Trailer Marine Transport Corporation, which provides service from Jacksonville and Miami, Fla., to Puerto Rico, with extended service to the Virgin Islands, Leeward and Windwards, and the Dominican Republic. All TMT barges are equipped with a fifth-wheel device that automatically locks trailers securely to the deck as they are driven onto the barge.

"The addition of these two barges will mark a new era in roll-on/roll-off t r a n s p o r t a t i on service for the Caribbean," said Mr. Collar. "We plan to continue using 9,000-hp tugs in the TMT service, and plans for construction of permanent tri-deck ramp systems are underway so that we will be able to continue our quick turnarounds." The barges are being constructed in Portland, Ore., by the Marine and Rail Equipment Division of FMC Corporation. Delivery of the first barge is scheduled for mid-March 1978, and the second for mid-June 1978.
