Global Supply Chain News: East Coasts Ports Continue Race to Handle Larger Ships

New Sailings from P3 and G6 Networks to Create Pressures Soon even with Panama Canal Delay; Depths, Tides, Port Rotations and More

 

SCDigest Editorial Staff

 

Major East Coast ports are continuing with varying degrees of success or rather speed to upgrade their capabilities to handle larger ships and process more containers.

The size of ships generally has of course been on the rise for a number of years. But East Coast ports were give a real wakeup call when the planned expansion of the Panama Canal was announced in 2006, a move that will allow much larger ships through the Canal, most of them headed to the US East Coast.

SCDigest Says:

Miami expects to have its 50-ft channel completed by 2015, while Savannah, Charleston, Jacksonville and Port Everglades are at least three years beyond this, and in some cases nearer to the end of the decade.

Most of those ports at the time would not have been able to handle many of the larger ships.

The Canal project's completion has now been pushed back again, until early 2016, while several ports are engaged in dredging and other projects they hoped to complete around mid-2015.

But even with the latest delay in the Canal project, there may be pressure on US ports even earlier anyways, due to recent change in container line consortia. Last year, Maersk Lines, the world's largest ocean container shipping company, formed an alliance with its two next largest competitors (Switzerland's Mediterranean Shipping Co. and France's CMA CGM) to share capacity on major shipping lanes in an arrangement it calls the P3 network (the companies are still awaiting regulatory approvals for the move).

Late last year, a rival consortium called the G6 network (Hapag-Lloyd, NYK Lines, Orient Overseas Container Line. Hyundai Merchant Marine, APL and Mitsui O.S.K. Lines) announced it was beefing up its route schedule to better compete with P3.

The net effect of all of that is the by pooling services, both networks will likely be in a position to sale larger ships handling at least 8000 TEU, versus the smaller ships that largely call on US East Coast ports currently. The cost efficiencies of the larger vessels are a key driver of the potential benefits to the container lines from the consortia.

If all goes well with the regulators, both the P3 and G6 networks plans to start sailing by the end of Q2 this year.

Just how large a ship a port can handle turns out to be a more complicated question than might be thought. The most important attribute, of course, is how deep the water is in the port area and any channels leading to the docks, usually measured as the depth at low tide.

But how a ship is loaded also impacts its draught. For example, according to Drewry Shipping Consultants, a number of current East Coast ports are now servicing ships that can hold 9000+ TEU on Asian all-water services via the Suez Canal, but that is because "the inbound cargo tends to consist of relatively low weight consumer goods, and outbound vessels have significant empties aboard, so maximum draught is never reached."

Conversely, Drewry says ships coming from Europe to the East Coast, which consist of the bulk of most EC port volumes, tend to consist of heavier industrial goods. Plus, the trade flow is relatively balanced, meaning inbound and outbound vessels can be well- laden with import and export containers.

"Fully laden with heavy cargo, a typical 8,000 TEU vessel has a draught of around 14.3 meters (47 feet) which, with under-keel clearance, would require channel depth of at least 49 feet (14.9 meters)," Drewry says - a depth only Baltimore, Norfolk and New York/New Jersey currently enjoy.

Further complicating matters, tides can fleetingly ameliorate base channel depth issues to a degree. For example, in Charleston, high water adds approximately 5.5 feet (1.7 meters) to its water depth, and other East Coast ports have a similar tidal range of around 6 feet, which could enable them to get to the 50-foot depths required for the larger ships in theory. However, the effects tides have "on permissible vessel draughts and tidal windows is complex," Drewry notes.

Finally, port rotations can also play a role, as a partially full ship after unloading stops at deeper ports may be able to enter more shallower channels if it carries significantly less weight.

Projects at Every Port

Almost every port has some active deepening projects. Miami expects to have its 50-ft channel completed by 2015, while Savannah, Charleston, Jacksonville and Port Everglades are at least three years beyond this, and in some cases nearer to the end of the decade.

It isn't easy to get such projects going. The channel deepening project at the port of Savannah received the last of its federal and state regulatory approvals in 2013 - after 14 years of study and review.

Although the height of the Bayonne Bridge fronting the New York/New Jersey ports is sufficient to permit ships in the 8-9,000 TEO level, there is an on-going $1.3 billion proiect to raise the bridge so that new 13,000-TEU Panamax vessels can get to Port Elizabeth.

Drewry nicely summarizes all the East Coast port projects in the graphic below.

 


There are also major concerns that larger ships entering the ports and unloading more containers will add pressure to so-called "landside" operations - SCDigest will cover that issue in more detail very soon.

Let's not overlook a huge, multi-million TEU market in the Gulf Coast in the conversation.  Ports like Houston, Mobile and Tampa enjoy deep water channels today (The Houston Ship Channel is 45ft deep and has a self-funded dredging program underway at its container wharves to match). Houston handled 1.95 Million TEUs in 2013, much larger than many of the ports mentioned in your article.
