- 2 new locks have been installed at the Pacific and Atlantic sides of the Panama Canal.
- More than 80% of the world’s fleet can pass through the canal now.
- It has affected the LNG carriers the most.
- It reduces the journey to Asia by 10 days.
The Panama Canal which became the game changer for maritime trade 104 years ago, has again set a new milestone. A year after the completion of its expansion project, the canal is now open to 80 percent of the world fleet tonnage. On 26 June 2016, Panama – COSCO Shipping Panama slowly glided along the 427- by 55-metre chamber, and while two tugboats carefully manoeuvred the vessel into the new locks, onlookers held their breath. The container ship was the first vessel to travel through the newly expanded Panama Canal.
18 months later, the new locks have become a grand success. More than 2,500 Neo-Panamax have undertaken the same journey. This expansion project has opened up a new shipping lane for larger, Neo-Panamax vessels. By installing 2 new set of locks at Pacific and Atlantic sides Canal, the size of the vessels moving through it has increased to a maximum length of 294 metres and a beam of 32.2 metres, to 366 metres and 49 metres, means that today 80 per cent of the world’s fleet can transit the Panama Canal.
The traffic flow at the onset
Initially, traffic at the new locks was slow. This is because the procedure for guiding ships through, has changed significantly. “Instead of pulling vessels through with locomotives mounted on each side of a lock, vessels are navigated through using tugboats– with one connected to each end of the ship. This process is a lot more complex than the locomotive system,” explains Marcus Ihms, Ship Type Expert Container Ships at DNV GL – Maritime. “But over the course of the first year, the speed at which larger vessels are processed has increased significantly. Since June 2016, the number of Neo-Panamax vessels passing through the new locks per day has climbed from one vessel in the beginning to an average of four ships per day in early 2017,” says Jeffrey van der Gugten, Market Analyst at DNV GL – Maritime. In May, the Canal Authority noted that this number had increased to an average of 5.9 vessels per day. In December 2017 the number of locks has been increased from 6 to 7 to meet the increasing demand.
Effects on LNG vessels
While container ships will have preference over other ship types when allocating the additional slots, LPG carriers were the most affected. So far, container ships and LPG carriers have been the segments that have made the most of the new locks, logging 1,147 and 636 transits respectively (as per November 2017).
Neo-Panamax LPG carriers which exclusively travelled from North America to Asia via the Cape of Good Hope in Africa are now been completely rerouted, with 100 percent of Neo-Panamax LPG carriers transiting through the Panama Canal.Although Neo-Panamax LPG carriers made fewer transits than container vessels yet they have felt the most impact of the new waterway.
Things To Consider
Operators interested in rerouting their services need to take several factors into consideration before booking a slot for an existing Post-Panamax ship. One of the biggest adjustments concerns the mooring equipment. All chocks and bollards, which are used for the towing operation, need to withstand a safe working load of 90 tonnes, since the tugboats manoeuvre the vessel with greater force than the locomotives would. In some cases, the Canal Authority require owners to change the existing mooring arrangement due to the new handling procedures.
In addition, the ship’s bridge needs to be equipped with five specific conning positions to be used by pilots during transit, and from which certain equipment and indicators have to be accessible and visible. The visibility requirements during the passage are generally stricter than those defined in SOLAS V/22. On laden vessels the view of the water surface from the conning positions may not be obscured by more than 1 × length overall (LOA) forward of the bow. For vessels in ballast, this figure is limited to 1.5 × LOA. And finally, pilots need to be provided with platforms and shelters to protect them from sun and rain.
These retrofit measures can be carried out while a vessel is afloat and do not require dry docking. “Their main purpose is to ensure that the mooring equipment can handle the forces of the tugboats and that the vessel doesn’t suffer structural damage while passing through the new locks. But we have seen that, even if ships comply with these requirements, passing through the new locks can still be demanding,” says Ihms.
Making it through
Overall, he sees the expansion project as a success: “The new locks can help vessels travelling between the East Coast of North America and Asia cut up to more than 5,000 nautical miles (a minimum of ten days) from their journey. And once we see everyone become a little more familiar with the new operational procedures, I think we will see transits become smoother and more efficient.”
However, the constant side wind is a problem and vessels passing through the canal have to adjust with it. “In the old locks this was not such a problem, because the vessel was fixed in the middle by the locomotive – but in the new locks, especially on the Atlantic side of the canal, vessels and their tugs can easily go adrift and slam into the edges of the funnel-shaped entrance at Agua Clara,” says Marcus Ihms, adding that several operators had reported such incidents here. The damage varied from smaller dents to significant gashes in the hull. To avoid this becoming a regular issue, Ihms recommends the installation of protective rubber fenders along the entrance of the Agua Clara locks.
Thus, except minor issues the new expansion has become a huge success.
