In another step forward for the Panama Canal Expansion Program, the second shipment of four rolling gates for the Third Set of Locks arrived today from the port of Trieste, Italy to the waterway’s Atlantic side on board the semi-submersible vessel STX Sun Rise.
“This is another milestone as we now have half of the 16 gates that will be used in the new locks,” said the administrator of the Panama Canal Authority, Jorge Luis Quijano.
Following a nearly one-month journey, the ship completed its second trip that began in mid-May in the Port of Trieste, crossing the Gibraltar Strait and maneuvering the waters of the Atlantic Ocean.
As opposed to the first shipment, these gates have two different dimensions, according to their final position in the lock chambers.
The taller, “Type C” gates were fabricated for lock head number 3 in the middle chamber of the Pacific locks. They are 57.6 meters long,10 meters thick, 31.9 meters tall and weigh approximately 3,900 tons, with all internal appurtenances installed. The shorter, “Type A” gates will be located in lock head 1 in the Atlantic site’s upper chamber, adjacent to the lake. They are 57.6 meters long by 8 meters thick and 22.3 meters tall, and weigh approximately 2,300 tons.
The four rolling gates will be disembarked in the dock especially built for this purpose on the Atlantic side.
While the two gates destined for the Atlantic complex will remain in the staging area until the time of their installation, the other two will be transferred to the Pacific site once the installation of the concrete supports is completed in the dock built for their unloading.
