Markey ARR Winch System: Tried & Tested in the Toughest Tug Challenges
For more than 30 years, Markey Machinery has worked with the LNG and marine transportation Industries with the goal of developing winches designed to work under the most challenging conditions. The effort includes extensive design shop testing and actual commercial work, a combination that has ultimately produced an understanding of the operational issues facing terminal and tug operators. The many milestones in the development of Markey’s Asymmetrical Render/Recover (ARR) – technology by which hawser winches are able to maintain mean line pulls up to the bollard pull of the tug – came over a period of time that spans 25 years. The initial 20+ years of hawser winch design and Render/Recover development followed a traditional design path, influenced, in part, by market pressures.
