파랑 중 접이안 거리에 따른 FLBT와 접안 선박의 유체동역학 계수 추정

Abstract

In generally, bunker oil is used in the ship’s fuel but exhaust gas occurs by using bunker fuel. Recently, regulations have been progressively tightened for a range of emissions. Using the Liquified Natural Gas(LNG) fueled ship is an alternative to solve the problem that emissions control area(ECA) is increased Floating LNG Bunkering Terminal(FLBT) is the floating facility in order to storage LNG and transfer LNG to LNG Bunkering Shuttle(LBS). For LNG bunkering process in FLBT, LNGC and LNG bunkering shuttle should be berthed. The criteria of environmental load such as wave, wind and current is very important because berthing of vessels is one of the most difficult areas in the operation of the vessel. In this study, we conducted a numerical analysis using the high order boundary element method and analyze the behavior and hydrodynamic coefficient by berthing distance to suggest the environmental criteria in berth.native to solve the problem that emissions control area(ECA) is increased Floating LNG Bunkering Terminal(FLBT) is the floating facility in order to storage LNG and transfer LNG to LNG Bunkering Shuttle(LBS).
