The Application of Fuzzy Inference System during Risk Assesment Process Study Case: 14" Subsea Pipeline PT. PHE-WMO

2019 Maritime Safety International Conference (MASTIC 2018)   unpublished
Potential hazard that could lead to the failure of the operations of gas pipelines 14 "PT PHE-WMO is often found in the offshore and onshore area. In order to prevent potential damage, the companies need to conduct risk assessment. This study compares the risk assessment approach between Muhlbauer and Fuzzy Inference System to get a proper risk assessment for gas pipelines 14" PT. PHE-WMO. Muhlbauer scoring system used in this approach i.e. third party damage index, corrosion index, design

On the other hand, Fuzzy Inference System approach applied in the scoring system is Mamdani method (Max-Min) that includes the formation of fuzzy set, the implications of the application functions, composition rules, and defuzzyfication. The comparative results of both RSS approach are used as consideration to determine the next appropriate mitigation step for gas pipe 14 "PT PHE-WMO. The calculation of pipe using fuzzy approaches provides greater difference value in RRs. The greater difference value of RRS makes it easy and clear in administering the rank for each segment of data input. Thus, the fuzzy method is more accurate and precise than the Muhlbauer.
