USS PAMPANITO (SS-383)
THE SECOND DRY DOCKING - 1993
The work we had done during the previous dry docking was evaluated at this time. The zinc anodes we had placed around the underwater hull were deteriorated, as expected, and several additional anodes were added. The free flooding chain locker had remained free of accumulated material and minor damage to the coatings was repaired. The interior surfaces of the submerged superstructure were examined and found to be in good shape. It was decided that the torpedo tube shutter doors would not be removed at that time and we would address this area in the next dry docking. The shaft tapers were in good shape except for the cloth wrapping around the shafts at the struts, so it was repaired.
This shipyard period was complicated by the damage to the outer shell that had been done in a severe wind storm that swept the Bay Area in 1988. The repairs required that over two hundred square feet of shell plating and several frame sections be replaced. Fortunately, the damage repairs were covered by insurance and our hull fund covered the rest of the expenses for additional work not related to the maintenance of the underwater coatings or the storm damage. The damage repairs substantially increased the time needed in the shipyard, instead of four weeks, the time of this haul out, the maintenance work could have been accomplished in five to ten days depending on the weather.
The hull fund was built up to the point that the cost of all the additional work was comfortably accommodated. We now think of the fund as the preservation fund.
