Abstract

The analysis of failure and reliability factors of impressed current cathodic protection (ICCP) design toward underwater line of warship (Case study in kri kcr-40 type)

Highlights

  • There is a common problem in the readiness of the Main Defense Equipment of Weapon System (Alutsista) of Navy Indonesia Armed Forces which is often faced with one of them, it is Corrosion

  • This research aimed to determine the factors of failure and reliability value of the design-based impressed current cathodic protection (ICCP) (Reliability by Design) with the Fault Tree Analysis (FTA) and failure mode effect analysis (FMEA) approach, the FTA aimed to identify the risks that contribute to the failure

  • From the results of data processing the determination of SOD rating obtained Risk Priority Number (RPN) results with the highest value, it is the component of "steel potential indicator and rectifier indicator" and the "fan" component

Summary

Introduction

There is a common problem in the readiness of the Main Defense Equipment of Weapon System (Alutsista) of Navy Indonesia Armed Forces which is often faced with one of them, it is Corrosion. This research aimed to determine the factors of failure and reliability value of the design-based ICCP (Reliability by Design) with the FTA and FMEA approach, the FTA aimed to identify the risks that contribute to the failure. This method was carried out with a top down approach, which began with the assumption of failure or loss from a top event detailed the causes of a top event to a root cause, whereas FMEA was a tool used to analyze the reliability of a system and the causes of its failure, by providing basic information about the system reliability prediction, design, and process
