Container ship dumps containers in Pacific

[GordMay]

A TEU or Twenty-foot Equivalent Unit is an exact unit, used to measure cargo capacity, for container ships, and container terminals.
There are two common international standardized container types: twenty, and forty feet long.

A twenty-foot equivalent unit (TEU) is a shipping container whose internal dimensions measure about 20 feet long, 8 feet wide, and 8 feet tall. It can hold between 9 and 11 pallets, depending on whether they are standard pallets or EUR-pallets. Two TEUs have the capacity of a single FEU, FEU = Forty Foot Equivalent Unit, both are used to describe the size of a container.

Thanks, it appears to cubic capacity of 20 and 40' containers.

Shipmates,

Some may agree and some may not. You can satisfy some of the people some of the time, and you even may satisfy all of the people some of the time, but you cannot satisfy all of the people all of the time. With that said, please allow me my opinion. Because of this new world of oceans littered with an unknown Number Of SeaLand Containers floating all over the world, I would say that money spent on a FORWARD-LOOKING-SONAR is money well spent. Better spend for that than lose Your Boat and maybe Your Life also.

Sailing4jesus, I do not have nor have I ever used a forward-looking sonar, so enlighten me: my understanding of it is that it “ looks” in a cone forward, and gives a return of that cone on a screen or display of some sort. If I have that part right(?) seems like the part of the cone that reaches the surface would be so far forward and diffused as to not be helpful. And I can imagine that depending on mounting location, the hull could obscure meaningful return in that upper sector, much in the same way a mast or funnel results in obscured or “ blind” sectors on radar. How much of this do I have right?

Thanks! I would have been more prone to a tare and a gross per container as stenciled on them. As I recall, it is the ships engine that coordinates loading from quite an array of gauges on the bridge deck. That may be the problem, insufficient attention the the center of gravity and the resultant reduction of GM. Time at the pier is money so cutting corners may be the problem.

Because the containers have to be offloaded in an order at the various ports of call which avoids double handling the loading plan is not carried out by the crew during loading it's done beforehand and these days is generally computerized. Consequently my money would be on design rather than operational failure.

TEU is more commonly used to describe the carrying capacity of container ships in the same way that deadweight tons ( when loaded ) are used to describe the size of tankers.

Maybe that is the problem? A bigger concern for the economics of LOFO than the weight distribution. Net profit. Out of curiosity does anyone know who dumps the most containers?

The individual containers have a rated load limit and it would be interesting to see whether they use this figure when they design the vessel or a lower average as they do for passengers in the airline industry.

Weight distribution is also included as a major "concern". A buddy of mine work on load planning of containers. It's all considered and weight distribution is the major factor influencing fuel comsumption.

I probably did not make the question clear? Which shipping company or country?

The term "dump" tends to create the wrong impression. They don't actually "dump" them, they "lose" them and whilst it's probable that the losses are often the result of carelessness or negligence of some sort they are not deliberately throwing them overboard. Dump is better saved for their crimes of "dumping" plastic waste or oil from tank cleaning etc. when we really need to emphasize the criminal nature of their activities.

You are correct. A poor choice of words. I'm not sure lost is any better. How about inadvertently discharged overboard.
