AN EXPERIMENTAL STUDY ON THE CAPTIVE MODEL TEST OF KCS IN REGULAR WAVES

Abstract

In order to investigate maneuvering characteristics of KCS in waves, captive model tests in regular waves were conduct-ed. Purpose of the test is measuring maneuvering hull forces in waves. Model tests were carried out using CPMC (Computerized Planar Motion Carriage) of ocean engineering basin in KRISO (Korea Research Institute of Ships and Ocean engineering). Total 6 degrees-of-freedom motion were fixed by two points supporting captive model test device, which is specially designed for the test. Several static drift tests were conducted in calm sea and in regular waves, varying wave amplitude, length, and direction. Hydrodynamic maneuvering forces in waves and hydrodynamic coefficients related to sway velocity were estimated based on the test results.
