Underwater Facilities Inspection and Assessment at Deperming Pier Trident Refit Facility, Bangor, Washington
The 254 of the total 650 piles in the Magnetic Silencing Facility Deperming Pier belonging to the Trident Refit Facility at Naval Submarine Base, Bangor, Washington not included in the Oct 1980 inspection, were subjected to a Level I and Level II inspection. In addition to the piles, 30 timber pole troughs which span the space between the finger piers and support the X-loop cables, were also examined and measurements of mudline to bottom of trough were obtained for every other trough. The overall condition of the examined piles is excellent. Eight piles have sustained minor mechanical damage in the form of ring shakes. In two piles this damage has resulted in marine borer (Bankia) attack. It is recommended that the above two piles with mechanical and marine borer damage be encased with plastic wrapping at the zones of damage. The cost of this would be approximately $5,000.00. Damage found in three piles during the previous inspection has been repaired. The overall condition of the timber troughs is good. However, extensive marine borer damage was observed in the timber framing members at the pole/bent joint. Several timber members restraining the cable assemblies have also sustained damage. It is recommended that a comprehensive and detailed inspection be carried out of all these members. Keywords: Underwater inspection; Washington(State).
