ASR - 21/22Four Point Moor Anchor Windlass Design Review,

摘要

This Center was requested to investigate and recommend alterations to correct difficulties being experienced by the ASR's 21and 22,USS PIGEON and ORTOLAN,during deep sea mooring operations. The difficulties being experienced by the ships were found to fall in the following categories: (1) Anchor chains jumps off wildcat during payout operation; (2) Electric motors overload and stall during anchor retrieving operations in 1000foot water; (3) Hydraulic components (pumps and motors) and fluid overheat; (4) Wildcat locking head dogs travel in their slots causing 'hammering'on the anchor windlasses;and (5) Wildcat shafts bushings (bearings) damaged during operations.
