Rapp technicians recently completed a winch drive retrofit for Otto Candies in Houma, LA, early this year. An existing Rapp hydraulic winch was converted to electric, making use of Rapp’s Active Heave Compensation (AHC) package. Rapp’s package includes a motor recognized at the 2010 Offshore Technology Conference (OTC) Spotlight on Technology ceremony. Its design features liquid cooling—despite the fact that the R&D team at the outset considered myriad air-cooled designs before opting for liquid-cooling. Owing to favorable acknowledgement in the industry, Rapp patented the design. The motors are mounted on Rapp’s own in-house manufactured gearbox, that it developed long ago for its hydraulic winch lines.
