THE MEASUREMENT OF HULL AND LINE SHAFT STRESSES IN RESPONSE TO CRANE AND SEA STATE LOADINGS, S.S. PHILIPPINE BEAR

Approximately eight weeks of wave, trim, and cargo induced stress data were obtained on a single LASH-type cargo vessel operating in the Gulf of Mexico, the U.S. Pacific West Coast, and the South Pacific Ocean to Australia. Data were taken from strain gages mounted on hull longitudinal and transverse members in the inner bottom structure, on the shaft thrust bearing casing and foundation, and on the lower main gear case and foundation, as well as strain gage telementry units mounted on the rotating propeller shaft. Specific hull and shafting response was ideally measured during short-term loading to two-million pounds by means of the vessel cargo handling lighter crane. Additional measurements of deflection were taken by means of a jig transit, linear variable differential transducers (LVDT's), strain gage deflectometers, and a laser alignment system.
