Abstract
Investigations related to assessing and improving ship structural reliability are discussed: (1) Breaking wave loading on the bow of ships. Steep wave impact pressures and the structural dynamic response of FPSO bows were studied using 1:80 scale instrumented models and time domain simulation. (2) The estimation of added mass of vibrating panels. The added mass on one side of various patterns of vibrating panels on a wall was investigated. (3) The estimation of fatigue and fracture behaviour of sharp corners found in most ship structural connections. A concept that involves treating the corner as equivalent to an additional length of crack was discussed. (4) A methodology for data gathering and reliability and risk assessment of ship structure.
