Cylinder base for Detroit Harbor aid #5,  filled with rock to create mass.

Detroit Harbor, Washington Island -  

The second of two steel cylinders was transported to Washington Island Friday afternoon, June 1st, and was lowered over H-piles where buoy #5 had previously been tethered on chain and concrete sinker.  Roen crews began filling each cylinder with stone from their second work barge, and by late Monday, both #4 and #5 cylinders were ready for concrete.

A stationary mixer truck on deck was used to combine gravel, sand and cement, then the product was pumped into the cylinder. (photo below)

The bulkiness of these new harbor additions will be hard to overlook, even without their 20-foot or so tall light towers, yet to be added.

By Thursday, June 7th, if work on the two cylinder bases is completed, the Roen work barges and crew may depart this location in preparation for their next contract.  The final stage of light pedestal installation will follow later, after shipment of the units is received from the fabricator.
