Monitoring Ship Stresses at Sea
In order to enhance safety during shipboard operations real time motion and stress monitoring information equipment can be supplied by Lloyds Register to a ship at the owners request. This entails the fitting of strain gauges to the deck structure, an accelerometer and a personal computer with software that displays ship stress and motion readings on the bridge. An alarm is activated if the safety limits are exceeded, enabling remedial action to be taken. Where this equipment is installed the notation SEA is assigned and if coupled to a data recorder the assigned notation is SEA(R).
