Henschel Announces New Steering-Failure Alarm

Already operating successfully aboard tankers of a major U.S. oil company fleet, the new Henschel Rudder Follow-up Failure Alarm meets the recently proposed U.S. Coast Guard rules requiring an alarm upon steering failure. It provides the required audible and visual warning in the pilothouse in the event of loss of rudder control from the pilothouse. The system consists of a bulkhead mounting alarm panel with attached bell for the pilothouse, a special rudder angle transmitter, and a synchro coupled to the helm wheel. It operates on the proven-reliable application of synchros, together with solid-state technology.

If, at any time while in either automatic (autopilot) or handelectric (full follow-up) steering, the rudder position ordered and the actual rudder position differ by more than five degrees for more than 30 seconds, the alarm is actuated. When in hand-electric (nonfollow-up) steering, the system is deactivated. The alarm system is totally independent of the steering gear control system and its power source, except for the mechanical connection of a synchro to the helm.

The system is ideally suited to retrofit existing ships as well as new construction.
