6Nov21. Dredging equipment seen at the mouth. Vessel A is a spud barge moored with through-deck pilings driven into the sand at the bottom of the water to provide stability and, perhaps, an additional crew boat. Vessel B is the 18" "Yellow Fin" suction dredge. Vessel C is a Marsh Master anchor barge. Vessel D is the amphibious Marsh Buggy with pontoon tracks good for wetland use. Vessel E is the spare discharge end screening device or basket.

The dredged material is moved to this disposal area located a short distance on the down drift side of the mouth. It is pumped through a hydraulic pipe seen laying on top of the sand that is connected to the dredge. The plan is to replenish beach sand further down the coast lost to coastal drift and wave action. Hopefully, the dredge material can be an important part of restoring/preserving the coast.
Section of completed dredging from Thu 10-28 to Fri 11-05 (estimated).

Based on daily reports, the following metrics have been calculated:
LF (Linear Feet) = 7,590 (78.2% of 9,700)
CY (Cubic Yards) = 208,203 (57.5% of 362,163)
From Fri Oct 29 through Wed Nov 03, the dredge’s guidance computer was down. They were not able to identify their current stationing for that time. What is shown on the sketches I’ve provided during the middle of the reporting period are estimates.
Rigid’s downtimes throughout the reporting period covered the typical items (moving anchors, cleaning pump and cutterhead, etc.). The major downtimes for the dredge was due to electrical issues, cable repairs, and pump and bearing maintenance. All in all, a fairly uneventful week, other than the guidance computer.
- Boaters please stay clear of markers, the dredge pipe, all equipment, and the discharge area.
