Bald Head Island Beach Renourishment Begins; Demonstrates Long-Term Terminal Groin Success

Under an $11.7 million contract, Marinex Construction Company of Charleston, South Carolina, began dredging in mid-January for a project on Bald Head Island in North Carolina. The company is moving sand from Jaybird Shoals to shore to both protect a rock groin and to add material to South Beach.

Using its 250-foot long, 24-inch cutter suction dredge Savannah, Marinex will remove an average of 10,000 cubic yards per day for a total of 1.1 million cubic yards from Jay Bird Shoals, which is a sand deposit that sits about a mile and a half from the beach placement area.

According to Thomas Payne, vice-president of Marinex, the Savannah’s size makes it ideal for working in shallower inland inlets and with nearshore borrow areas. In addition to the dredge, the company is also using two tender vessels, a standby tug, and anchor barge and a crane barge.

Work began in mid-January and is expected to be completed by the end of March.

“The great thing about working at Bald Head is that Jay Bird Shoals, in most situations, is blocked by winter (weather) patterns where southwest winds make it rough at the shoals. With that and that the island is secluded with little pedestrian traffic, things go faster,” Payne said.
