Dredge Report | Week of January 3, 2021
Sand ShifterÂ
The Sand Shifter was back dredging on Thursday after a few days of being out of action after a âwear linerâ was damaged and needed to be replaced (see pictures below). The repair required the Sand Shifter to be brought alongside the dock in the Pocasset River, removal of the top deck of the engine room/dredge pump section, along with the dredge pumps main housing, where the âwear linerâs is located (not a simple task). A crane had to be brought in over two days to remove the damaged âwear linerâ and install the new one. Fortunately, a replacement âwear linerâ was on hand which reduced the time that the Sand Shifter was out of service.Â

Wear Liner Showing Damaged Section
The âWear Linerâ is at the receiving end of the dredged material and protects the large impeller that creates the âsuctionâ moving the material through the pipe onboard the dredge.
As the part is named, the âWear Linerâ is designed to wear away and its life expectancy is related to the volumes & hours dredged, along with the type of material dredged. The Little Bay project had several areas of rocks of various sizes which do their part in hastening the damage to the âwear linerâ.
Typically, rocks smaller than 7â pass through and make their way to the dewatering basin.

We are nearing the end of this project and hope to be completed by mid-week.
Link below does a great job in explaining how some of this sand will be used for beach nourishment in Sandwich.

Cod Fish II
The Cod Fish II is still in Provincetown Harbor along with pipe awaiting a couple of calm days to make the trip to Sesuit. Hoping that this week brings better weather.
