Metis

The Metis was a mid-sized lake freighter, that subsequently had her bridge and engines removed, when she was converted to an unpowered barge. After conversion, her stern has a large notch, into which a tugboat's bow is inserted to push the vessel.

ESSROC, a cement company, operates the vessel. Her relatively small size allows her to visit smaller ports near the quarries where limestone, a key ingredient of cement, is mined.

Unlike larger or more expensive vessels, the Metis carries a conventional land-style crane to make the vessel capable of loading or unloading her holds.
