| Abstract | Since Vietnam has had oil terminal system development plan, more tank projects have been invested to expand storage capacity. However, quality violation has been alert obviously. From that point, the study suggests model to identify and eliminate those problems beforehand. The study used one tank project as case study to fulfill three objectives. Firstly, quality assurance processes in traditional procurement were modeled. Then, the researcher investigated problems adhering to these processes. Finally, an improving quality model was suggested addressing those problems. The case study was collected from Petromekong Corporation located in southern part of Vietnam. The researcher utilized focus group qualitative method. The researcher discussed with investing department of Petromekong to elicit quality assurance activities of project participants. Then, the researcher defined five problems existing in the case: deigning unavailable material on market, delaying in pressing piles, supply delay of floating roofs, leakage of valves and oil leakage of existing tank system. The researcher looked for some quality improvement approaches from manufacturing industry since. Finally, after conducting expert’s assessment, the researcher demonstrated “supplier partnership” approach should be used in long lead time materials and equipment construction to improve procurement quality. Illustrating pile driving and oil transferring processes as examples, the researcher suggested a chain of tools to detect and solve those problems in the case study beforehand. Such tools are flowchart, check sheet, problem source investigating chart, brainstorming, affinity diagram, fish bone diagram, nominal group technique should be used orderly to improve repetitive, measurable and clear procedure construction processes. |
