Analytic Hierarchy Process Analysis for Industrial Application of LNG Bunkering: A Comparison of Japan and South Korea

From January 2020, the International Maritime Organization has regulated ship emissions to reduce sulfur content. As an alternative this, LNG bunkering was proposed, and infrastructure ships were deployed. Therefore, we used analytic hierarchy process AHP techniques determine optimal methods of for shipyard safety. First, conducted a literature survey on concept type bunkering, global trends, features Japan South Korea cases compared them. Thereafter, expert conducted, data analyzed using techniques. Finally, derived applicable industry. The analytical results revealed that priority method in order STS method, TTS PTS method. result this study can serve as theoretical basis make safer more economical shipyards prepare expansion demand LNG-fueled LNG. However, inevitably limitations ranking reversals paradox it by experts, assuming no weights STS, TTS, or PTS.
