A Study on the Manoeuvrability of KVLCC2 by Indoor Free Running Model Test in Calm Water

Abstract

This paper aims to study the manoeuvrability of KVLCC2 based on the indoor free running model test (FRMT). A position measuring system is developed by the electro-optical auto-tracking instruments, i.e. total station, for the indoor FRMT. The model ship speed is estimated by applying the low-pass filter to the data by Euler differentiation of the position measurement. The position and speed measuring system is verified by the outdoor and indoor test data produced by RTK-DGPSand the towing carriage. A 1/100 scaled model is used for the manoeuvring test. Straight-line speed test, 35° turning test, and 20°/20° zig-zag test are carried out in the ocean engineering basin of Korea Research Institute of Ships & Ocean Engineering (KRISO). The KVLCC2 FRMT results of this study are compared with those of Maritime Research Institute Netherlands (MARIN) and National Research Institute of Fisheries Engineering (NRIFE).
