Abstract This paper describes the design, fabrication and preliminary testing of several types of corrosion measuring probes developed for use on maritime vessels. The probes are part of a system utilizing the electrical resistance method for continuously monitoring corrosion during actual operation. One type of probe to be described is intended for monitoring corrosion on either the exterior surface of the hull or interior structural members in large compartment. Another probe has been developed for measuring condenser tube inlet (tube end) corrosion. A third probe has been developed for measuring corrosion in crevices and pipe lines. Both laboratory and simulated service testing has been carried out. Results of these tests and the effectiveness of the probes in measuring corrosive conditions on ships are discussed. 2.4.2

Steel Deck

The present study employs an electrical resistance method for fatigue crack detection in steel deck. The detection influential factors are analyzed via the finite element analysis under different electrode space and deck width. As a result, the electrode space influenced on detecting precision, and the smaller the better. The resistance measurement method is presented, and the formula of fracture damage ratio and the equivalent crack depth are established. It is proved by fatigue crack detection experiment of U-rib specimen, which shows that using electrical resistance method to detect fatigue crack is feasible.
