PURPOSE: A portable device and a method for inspection a leakage of a compressed gas storage tank are provided to use high pressured air being autonomously supplied in a ship or a shipyard, thereby enabling to miniaturize an inspection device. CONSTITUTION: A portable device for inspection a leakage of a compressed gas storage tank comprises a storage unit(110), an IBS adiabatic unit(200), a portable pressure sensor(530), and a first portable pump(510). The storage unit maintains air tightness by using a first screen film(P1). The IBS adiabatic unit maintains the air tightness by using the first screen film and a second screen film(P2) in the outside of the storage unit. The IS adiabatic unit maintains the air tightness with the second screen film and a hull(P3) in the outside of the IBS adiabatic unit. The portable pressure sensor measure pressure variations of the IS adiabatic unit in one side of the IS adiabatic unit. The first portable pump forms vacuum in the IS adiabatic unit by being arranged in the other side of the IS adiabatic unit, thereby inspection the second screen film.
