The Dredge Report | Week of April 4, 2021

Cod Fish I & Cod Fish II – Popponesset Bay, Mashpee

Locus

Dredging continued on Monday but on Tuesday morning the Cod Fish II experienced a mechanical breakdown. The clutch on the main engine ‘seized’ forcing the shutdown of the engine. The dredge was brought into the Cotuit Town dock for repairs. Fortunately, the Sand Shifter was in-between projects and we moved to Mashpee on Wednesday morning to resume dredging on Thursday morning.

A replacement part was on the shelf at the dredge manufacturer (Ellicott Dredge) and was delivered on Thursday morning. On Friday the parts were swapped out and the engine was back up and running by Saturday late afternoon.  As stated often, in the marine environment, and in pace that our equipment is run, breakdowns will occur, but its how quick the repair can be made. In this case, kudos go to Dredge Superintendent Jason Bevis and Maintenance Engineer Rich Randall for the fantastic job they did in making this repair. Bravo Zulu!

On Saturday dredging had to stop as the crew had to move one section of the pipe that crosses over the dune/spit due to the pair of Piping Plovers that are in this zone.

Just 1 1/2 days were lost due to the mechanical breakdown. The total number of days dredged this week were 4 1/2 days, total number for this project is now at 6 1/2 days. Target volume is 9,900 Cubic Yards.

Much of the week was spent on breaking down the pipe and equipment from the beach face and parking areas.
