The Skagit TMWW series combination wire rope/chain system is specifically designed for deep water mooring of offshore drilling vessels. The TMWW is electrically driven through a Skagit two-speed gearbox with a water-cooled dynamic disc brake for high-speed payout of the wire rope or chain.
Each traction winch/windlass is furnished with band-type brakes which are spring-set, air-released and designed to meet the necessary regulatory agency requirements. |
