What Would It Cost to Build a World-Class Dredging Vessel in America?

"According to Wikipedia": the three most trusted words in information!

I will say that this is a pretty firm usage if you're in the US, though.  I've only tangentially worked with dredges (I've been on board ... (read more)

What Would It Cost to Build a World-Class Dredging Vessel in America?

Answering your question: Efficient shipping requires a deeper channel than normally exists naturally, and a dredge is used to create a channel of the desired dimensions.  And, of course, since it's not a natural river bed nature keeps trying to make it on... (read more)

A Brief Introduction to Container Logistics

The Port of Long Beach, whose problems instigated the post the OP is responding to, publishes container movements here:

There's enough uncertainty in both of those figures I wouldn't take it to the bank, but it shows that shipping volumes have increased at the port.
