실선 성능 해석을 위한 ISO15016:2015 기반 방법론의 적용

Abstract

ISO19030 was developed in order to prescribe practical methods for measuring changes in ship specific hull and propeller performance. ISO19030 was expected to give a set of relevant performance indicators for hull and propeller maintenance, repair and retrofit activities. However, as presented in previous HullPIC conferences, results of ISO19030 is not yet fully verified to give reliable performance indicators. On the other hand, ISO15016 was developed to provide a set of standard methods to analyse results of speed trials of newly built ships with the accuracy of 2% in shaft power and 0.1 knots in speed, if all requirements are met. However, as ISO15016 is intended to be used for sea trials, which are run on somewhat controlled environment with as low environmental forces as possible, some part of ISO15016 is not applicable to ships’ operational data. This paper proposes a new method based on ISO15016:2015 and presents results of applying to operational data of bulk and container carriers and identifies benefits over ISO19030 in ship performance.
