As the demand for powerful escort tugs to safeguard tanker carrying volatile cargoes in coastal waters grows, the vital connection between the tug and its tow has become a critical component. Modern high-tech, manmade fibre towlines for escort tugs are light and extremely strong but to be fully effective the towing winch used must also be up to the job.
Andrew McAllister is equipped with a JonRie winch powered by Hagglund Drives. Winches from JonRie InterTech LLC, based in New Jersey, USA, are developed and manufactured to operate reliably under the extreme conditions and high transient loads experienced in escort work. In order to accomplish the high standards of performance required JonRie has established a good working relationship with Hagglunds, a well established supplier of hydraulic motors and drives based in Sweden.
Mr Brandon Durar, chief designer and president of JonRie explained, "As tanker escorting has become mandatory for more ports worldwide, escort winches have become more advanced to withstand the extreme steering forces and transient loads.
Active escort tug towing winches are now a "safety critical" component. The tow winch forms the live connection between tug and tow. Precise control and a wide safety margin is crucial to the tug's effectiveness. Towing winches need to work "out of the box", stay running and withstand the strain of the tug, crews and the sea. It's that simple."
Asked about the importance of winch drives, Durar said "It all comes down to the drives and there is nothing on the market to match Hagglunds' drives. They are well built, well designed and meet the needs of the maritime industry."
