GIANT NEW WINCH BUILT TO PULL UNDERSEA PIPE

Recently, Pengo Hydra-Pull Corp. delivered a marine hydraulic winching system to J.H. Pomeroy & Co., Inc., for use in pulling offshore submarine pipelines. First application for this large capacity will be in the immediate future when Santa Fe-Pomeroy plans to pull a 14,500-ft, 44-in. dia pipeline from a refinery site to an offshore mooring buoy location. This system is one of the largest hydraulic winches ever built when both full drum pull and drum capacity are considered. The 2.5-in. dia wire rope which will be used has a breaking strength of approximately 300 tons. The system's maximum tension can be present and line pull cannot exceed the set value. By reducing or eliminating the effects of accidental overloads, the wire rope can be used to somewhat higher limits. An illustration shows how the winch will be located on a derrick barge and how the barge will be anchored.
