Benefits of slow steaming exaggerated?

Studies by Simpson, Spence and Young, a leading global shipbroking firm, seem to indicate that emission benefits of slow-steaming have been exaggerated.

One reason offered is that the ‘cubic law’, which says that fuel consumption rises as the cube of ship speed, is erroneous for many vessels, and is only approximately true at the designed speed of the ship.

Another problem is that slow-steaming effectively reduces capacity, requiring more ships to cover a route with a regular schedule, for instance. Those extra ships produce more emissions even though the per-ship emissions might be smaller.

Capacity is not a problem at present. There’s not enough cargo. But scheduled service may suffer.

There are a lot of moving parts in considering emissions release.

The best way to attack the problem may be to get to zero or low-emission ships as quickly as possible. But in the short run, these considerations in he study are worth thinking about.

Ammonia-powered West Australia to East Asia green corridor in five years

The West Australia – East Asia Iron Ore Green Corridor Consortium has released a study showing the way for a green corridor to use ammonia fuel. The study looked closely at the capability of the ports to provide ammonia bunkering and sources of clean ammonia.

Ammonia-powered ships could be a reality quickly, because the engine architecture is very similar to current marine engines. However, storage of ammonia bunkers at sea is still an issue, and safety standards have not yet been designed.

The consortium started in November of 2021, with major charterers BHP and Rio Tinto, and shipping companies Oldendorff Carriers and Star Bulk Carriers working jointly to make the corridor successful.

I was unsuccessful in finding a copy of the actual report online. but it’s good news, because this route is one of the major world bulk carriage routes, and reductions in emissions will be helpful.

Rail storage fee disputes – STB or FMC?

When containers go by rail to or from ports, we would expect that any detention or storage fees would fall under the Surface Transportation Board (STB) which governs rail traffic in the US. And these fees have become more common, as railroads in the US struggle with manpower shortages, longer trains, lower traffic, and efforts to operate in a leaner fashion. But who to send the bill to?

Many containers are owned by ocean shipping firms, and it would seem like they should be billed if their containers are not picked up in a timely fashion. But it’s the shippers who get the bill.

The Federal Maritime Commission (FMC) has come down with some fairly explicit rules about detention and demurrage charges. The rules specify who is billed, what information must be provided and when, and how disagreements over bills can be resolved, through a process. But when the charges are from rail detention, the FMC claims they have no jurisdiction.

Shippers think the ocean carriers should be billed, and bill disputes be handled at the FMC under the new rules. But ocean carriers think the STB should handle rail demurrage.

I don’t think this can be settled without some Congressional input. It’s one of the gray areas that come up often in logistics, where many partners collaborate to move cargo or cause delays. The parties are never going to agree. For ocean carriers the divided authority is just fine; since they are not getting the rail bills, they have no stake in disputes.

We just need to get a single point of oversight, to lay down rules, like those of the FMC, for demurrage and detention charges including the rail lines. It’s a big ‘just’.
