KCS 선형의 천수역 벤치마크 조종모형시험

Abstract

Recently, manoeuvring ships in shallow and confined waters has again become an issue to people with an interest in safe shipping. In accordance with this trend, the main focus of SIMMAN 2014 is manoeuvring ships in shallow water. The organizing committee of SIMMAN 2014 requested that many international research institutes conduct captive model tests of KCS in shallow water, and requested that they submit test data for comparison. To fulfill this request, a false-bottom facility was built at the Maritime and Ocean Engineering Research Institute (MOERI)/KIOST towing tank. At this new facility, several captive model tests on false-bottom, including HPMM tests, were conducted to check the feasibility of such testing in shallow water. This paper presents the results from the benchmark HPMM tests, and the results of several supplemental tests carried out to check the overall reliability of the test results. Tests were done for three water depth-over-draft conditions (H/D = 2.0, 1.5, 1.2). Among several scale models of the KCS, a 1:31.6 scale model ship was selected for the HPMM tests above a false-bottom, considering the size of the false-bottom and the expected magnitudes of the resultant forces and moments. In collecting and analyzing the data from these HPMM tests, several issues were caused by constraints of the HPMM device, and from the size of the false-bottom.ganizing committee of SIMMAN 2014 requested that many international research institutes conduct captive model tests of KCS in shallow water, and requested that they submit test data for comparison.
