Crews have installed a containment boom between the Mike and November piers at the Veterans Terminal in North Charleston following the collapse of a bulkhead this week, the State Ports Authority said Wednesday.

On Sunday morning, port personnel discovered a portion of the bulkhead wall between the piers failed, said SPA spokeswoman Allison Skipper. The wall, composed of sheet piles with a 10-foot-high concrete bulkhead, supports a gravel storage yard used for the stockpiling of rock, she said. No one was hurt.

The affected area was secured on the landside, and crews installed a containment boom on the waterside, Skipper said.

Skipper said there was no indication of pollution from the incident, and salvage efforts were ongoing as of early Wednesday.

Port engineers and contractors are trying to determine what caused the failure of the bulkhead, which was built in the 1970s.

The SPA began leasing the former Navy facility in 1999 from the Charleston Naval Complex Redevelopment Authority.
