Fatigue reliability and service life prediction of aluminum naval ship details based on monitoring data
journal contribution

promoted an increasing interest in lightweight high-strength materials. Due to its strength and
weight characteristics, aluminum has been proven especially suitable as construction material for
hull structures, as well as other vessel parts. However, fatigue in aluminum naval crafts needs to
be effectively addressed for the proper life-cycle assessment. Structural health monitoring
(SHM) systems constitute effective tools for measuring the structural response and assessing the
structural performance under actual operational conditions. In this paper, an approach for using
SHM information in the fatigue reliability analysis and service life prediction of aluminum naval
vessels is presented. The accumulated fatigue damage and the fatigue reliability are quantified
based on SHM data acquired under different operational conditions, specified by the ship speeds,
sea states, and heading angles. Additionally, an approach for estimating the reliability-based
fatigue life under a given operational profile is presented. Seakeeping trial data of an aluminium high-speed naval vessel are used to illustrate the proposed approach.
