N1 - Funding Information:
The experiment for measuring the pressure distribution on the ship hull was conducted by a joint team of Osaka University and Hiroshima University. The authors are indebted to contribution of that joint team, especially its leader Prof. Hidetsugu Iwashita of Hiroshima University. The present work was done partially with JSPS Grant-in-Aid for Scientific Research (A), Grant Number 17H01357.

N2 - In modern shipbuilding industry, merchant ships tend to increase in size. Accurate prediction of the vertical bending moment in large-maplitude waves has become important for structural design. For establishment of an accurate estimation method, more detailed local hydrodynamic quantities such as the spatial pressure distribution on the whole ship hull surface should be checked. For that purpose, the experiment has been conducted by means of Fiber Bragg Grating (FBG) sensing technology. Using the measured local pressure distribution by only sticking the FBG pressure sensors onto the hull surface, we can evaluate the wave loads; which may lead to establishment of a new evaluation method for the wave loads without using a segmented model. We confirm favorable agreement of the pressure distribution between measurement and computation by Rankine Panel Method (RPM). Furthermore, the vertical bending moment computed at some transverse sections shows favorable agreement between measured and computed results.
