(The) study of ships' safety domain based on the Philippine navigators' risk perception index
Dimailig, Orlando S Mokpo National Maritime University 2018 국내박사
Abstract This paper conducted a study of the risk perception of the Philippine navigators while navigating the approaches to harbors, either maneuvering at inner harbor or outside harbor, but near coast. The aim is to construct an index on safety domain of the minimum safe distances relative to the ship’s four-cardinal sides when navigating within the proximity of hazards that may cause risk and danger to safe navigation. Being the major source of manpower in the maritime field and one of the sources of navigating officers, the paper chose the Philippine navigators as the subject of the study. The paper uses a descriptive research through questionnaire survey. It carried out the survey with the experienced navigators and collected 71 return responses wherein descriptive statistics, ANOVA and Cronbach’s Alpha, are used in testing the significance and content reliability. It also uses Pearson-Product Moment Correlation for comparing the variables, mostly the types of vessels, in relation with the adverse effects of restricted visibility, strong winds and currents in navigation. The statistical analysis is contained in Chapter 4. Chapter 2 presented the various related maritime traffic risk assessment and evaluation models presently in use or studied. It presents the transportation phenomena, difficulty in maneuverability caused by land and environmental stresses (ES), traffic phenomena, FSA, MARA, PMSC, US evaluation models. It also extensively demonstrates the IALA risk management tools, PAWSA and IWRAP. Chapter 3 lays out the data collected from the survey and presents them in graphical and tabulated forms. It, then, concludes with the outcome and recommends a continuum of this study to make full use of its findings. Among the outcomes of the study, the minimum safe distance was found to be strongly significant and there is reliable association with the variables. The perception of fear when measured from the different encountering scenarios and condition are almost constant in the four-cardinal sides of the ships. At inner harbor: ahead 7.0 LOA, stb’d 5.4 LOA, port 5.5 LOA and astern 5.9 LOA. When navigating at outer harbor, the results are: 7.7 LOA, 6.5 LOA, 6.4 LOA and 6.5 LOA, respectively. In the perceived level of fear, the dominant levels are ‘minimal’ at –1, and ‘considerable’, -2 which means that the navigators did not show undue fear perception when meeting vessels at inner harbor and in the periphery of port approaches. Key words : Ship’s domain, Minimum safe distances, Philippine navigators, Risk management, Risk perception index, ES model, Marine traffic
