When it comes to transiting the new locks on the Panama Canal, not all ships are created equal.
In the original configuration of the waterway, small locomotives are used to pull ships through the locks. In the expanded section of the canal, tugboats are used to move the vessels along.
In both situations, lines from the train or tug run through openings in the ship’s hull called chocks and then are secured to bollards.
But those chocks and bollards have to be able to stand up to the forces experienced during a towing operation. Plus, they need to be in the right spots on the ship.
“Every ship has chocks and bollards,” a shipbroker with maritime experience said. “But they might not be strong enough to be pulled by the tugs or might not have been in the right position.”
According to Capt. Guillermo Manfredo, executive manager for operations/canal operations captain, up to four tugboats are used to maneuver ships into the locks. Once in the locks, one tug is on the bow and one or two are on the stern, depending on the ship.
The new requirements came with plenty of advance notice, Manfredo said.
Back in August 2012, four years before the Neopanamax locks opened for business, “Vessel Requirement for the Panama Canal,” was published, detailing where chocks and bollards had to be placed.
Since the Panama Canal can now handle tankers as large as a Suezmax, most newbuilds up to that size will have the necessary chocks and bollards in the correct positions.
That was the case when the Aegean Unity, the first Suezmax laden with crude transited the canal in August. The ship first hit the open water earlier this year.
Some shipowners have taken it upon themselves to retrofit their vessels so the tankers can pass through the Panama Canal.
“It would behoove people to get it done,” the shipbroker said.
