Crowley Ships Massive Electrical Equipment
Crowley Maritime Corporation’s liner services group recently transported two massive electrical equipment enclosures with a combined weight of 196,000 pounds to San Juan, Puerto Rico.
Crowley said the feat required shifting the company’s 580-foot triple-deck barge La Princesa beside its normal berth at the Crowley terminal in Jacksonville, Fla., so that the pieces could be rolled onto the lower deck of the barge free of obstruction from the loading ramp.
“This orchestrated shifting of the barge and specialized loading operation is not commonly done,” said John Hourihan, senior vice president and general manager, Puerto Rico services. “The Crowley team not only came up with the solution for handling this heavy, oversized cargo, but executed the plan safely and successfully.”
Crowley was contracted by ATS International (ATSI) for the ocean transportation of the 12-foot wide, 16-foot tall, 63-foot long enclosures, which contained generating equipment. ATSI handled the over-the-road transportation and delivered the enclosures to the port on over-length, four-axle specialty trailers. To safely load the cargo, Crowley’s tug Sentry pushed the barge 100 feet beside its normal berth, where it was secured to the dock with wires and chains. The barge was then ballasted down to match the dock height while two contracted harbor tugs pressed against it on opposite sides at 90-degree angles to hold it in place. With the barge and dock level, the trailers were backed onto the vessel. Wood matting was laid in two trailer lanes prior to loading to create lanes large enough to accommodate the width of the trailers. Altogether, the cargo took up eight trailer spaces front to back on one side of barge.
After arrival in San Juan, the cargo was backed off of the barge and securely stowed until dispatch to ATSI.
