High-Frequency Ship Response Assessment of Large Containerships

To assess high-frequency ship response for rule development purposes of large modern containerships, numerical predictions were compared with experimental data. Numerical results relied on a technique that superimposed rigid body motions on elastic hull girder deformations. A finite element Timoshenko beam idealizing the hull was two-way coupled to a RANS solver. Experimental data were obtained from model tests of a segmented 10,000 TEU containership equipped with load cells, accelerometers and pressure sensors. A long-term measurement campaign onboard a 4,600 TEU Panamax containership yielded full-scale measurements. Predictions accounting for high-frequency response yielded higher section loads than those based on rigid body assumptions.
