Electrical Repairs of Piers 2, 6, 7, and 11

Electrical Repairs of Piers 2, 6, 7, and 11, Naval Station Norfolk, Virginia

This project provides the design for the repairs of Piers 2, 6, 7, and 11, which each feature four berths for the docking of Navy vessels, including but not limited to aircraft carriers, supply boats, combat ships, and more. Piers 2, 6, and 7 each had identical scopes and were brought up to date with Pier 11 in order to provide electrical power supply to berthed and occupied ships by mobile power stations (MPS) on rails located on the lower deck of the piers. Each pier has four MPS, one at each of the four berthing stations, featuring a rail and tracks to move along for when ships dock for maintenance or general power needs.

On the underside of the piers, above the water, exists all electrical conduit bundled into racks running the length of each pier. RQ-Blackwater JV demolished and provided new conduit where necessary, and designed and installed stainless steel frames to protect the under-pier conduit from buoys and rising water levels. In order to perform this scope of work, our team used barges to install the protective web of steel framing. While Pier 11 already featured MPS, it was upgraded to receive stationary power stations (SPS) and required minimal concrete curb updates.
