The Noble Discoverer is a turret moored drillship built in 1976. It has 8 mooring winches with 2-3/4" wire rope.
The existing mooring monitoring system needed to be upgraded with more accurate sensors, local displays for the winch operators, alarm evaluation for tension and payout issues, and PC-based data-logging for winch and operator activity.
Rugged Controls provided 8 RL30 running line tensiometers built with sensors rated for a Class 1, Div 2 (Zone 2) environment. We also provided 4 local winch displays and 4 remote displays enclosed in explosion proof enclosures. Finally, our WinchDAC software was utilized to provide both remote, real-time and historical data-logging capabilities for the bridge of the vessel.
