Paper presented at the The 32nd International Ocean and Polar Engineering Conference, June 5–10, 2022
Paper Number: ISOPE-I-22-340
... ABSTRACT This paper presents an experimental study on wave loads and hydro-elastic responses of a very large container ship in irregular waves. A segmented ship model with variable cross-sections backbone is newly designed to meet similarity conditions of vertical, horizontal and torsional...

Paper presented at the The Twenty-fifth International Ocean and Polar Engineering Conference, June 21–26, 2015
Paper Number: ISOPE-I-15-065
.... The ship model has six segments connected by a steel backbone and the scale is 1:60. For the measurement of stern slamming load, 5 load cells were distributed on the stern area. The stern slamming impact were measured towing the ship model in regular and irregular waves. Head and following sea conditions...

Paper Number: ISOPE-I-14-340
... elastic backbone has been fitted on the model, and an innovative procedure for torsion measurement has been proposed. The first part of the paper is dedicated to the new measurement method. Torsion induced strains in the model backbone are influenced by the entire distribution of torsional moment, so...

... backbone where a number of strain gauges were installed to measure structural responses. A number of force and pressure sensors were distributed on the bow-flare section in order to measure the temporal and spatial distribution of slamming load during tests. Based on the measured data, characteristics...

Paper presented at the The Twenty-fourth International Ocean and Polar Engineering Conference, June 15–20, 2014
Paper Number: ISOPE-I-14-338
... Abstract Backbone structure is widely used in model test to investigate ship elasticity such as springing and whipping because force measurement and stiffness similitude are both possible with backbone. Measured strains on backbone can be converted to vertical bending moment (VBM) or torsion...
