Proposed Improvement on Availability of Sarawak Marine Aids to Navigations by Using FSA And Swiss Cheese Model

Abstract

The study started with obtaining aids to navigation maintenance data year 2014 to 2016 from Marine Department Sarawak Malaysia. The data is used to determine the availability percentage of Marine Aids to Navigation (AtoN) in Sarawak according to type of equipment. The navigation buoy availability was below the standard set according to IALA and QMS. Formal Safety Assessment (FSA) was used to asses risk by unavailability of navigation buoy. Fault Tree Analysis was used to identify the root cause of failure. Swiss Cheese Model (SCM) was used to identify the management related cause at various management level. Risk control options were proposed based on findings in the FTA and SCM. The best risk control option proposed to top management was based on the five-level cost and effectiveness matrix of Cost-Benefit Analysis. Result of this research is applied to reduce the downtime of navigational buoys and would improve the safety of navigation in Sarawak waters.
