About this file
This document contains a grounding diagram and specifications for a pier and maintenance facility construction project. The project will construct a general purpose berthing pier and trestle with controlled access, as well as a vessel maintenance facility including parking, fuel distribution and storage systems. The facilities are required to support the Maritime Force Protection Unit at Naval Base Kitsap in Bangor, Washington in providing security escort and defense missions for submarines transiting to test ranges. The grounding diagram specifies that a ground connection be provided at each end of pilings and within equipment slabs, and shows the routing of ground conductors to various structures and equipment.
