Decision Analysis for Cleaning Method Selection of 26” HCT Shipping Line

Abstract

Many Oil and Energy companies are taking various efficiency and optimization measures that the pipeline facility that is no longer used for operation can be dismantled to reduce maintenance cost and inspection costs. The 26” HCT pipeline owned by Oil Energy Indonesia (OEI) has experiences leakage problems, significant thinning of pipe thickness which can lead to environmental soil pollution and hazard potential to residents around the pipeline. This final project aims to formulate a solution from the proposed alternative cleaning identified in the pipeline. The final project result is selection of several alternatives. Pipe condition problems were evaluated using Kepner-Tregoe (KT) Situation Analysis. The pipeline condition root and safety problem is then analyzed using KT-problem analysis and verified using 5 whys method. In obtaining alternatives that have potential as a solution to the existing problems, Value Focused Thinking method is used. Then alternative selection process uses Simple Multi Attribute Rating Technique method. Qualitative analysis is carried out through group discussions of four people who have deep knowledges and experiences. Alternative proposed to clean the pipeline using De-oiling method.
