ITB

as in “integrated tug-barge,” as distinguished from “articulated tug-barge,” now in greater favor. Here’s the tug portion of ITB Philadelphia uncoupled in GMD drydock from its intimate partner barge. Yes, that’s a tug.

 

For a sense of scale, watch the self-propelled crane aka “man basket” at floor of dry dock.

 

Yes, there is a dock worker in the man basket.

 

For a company diagram of this vessel to see tug integrated with its barge, click here.Top down view fascinates me.

 

ITB Philadelphia has an LOA of almost 700 feet, with the intergrated barge!

More on this vessel later.
