FIELD: gas industry.
SUBSTANCE: group of inventions relates to tank (1) for transportation and/or storage of liquefied gas. Reservoir contains insulating layer (2, 3) and a contamination removal system providing for removal of potential gas leaks, which may occur in insulating layer (2, 3). At that, reservoir (1) includes one sealed membrane (5), which limits internal volume (4), for production of liquefied gas, which is divided into two sections by horizontal median plane (200). Contamination removal system comprises one contaminant removal pipeline (8) provided with vertical resultant section (82) extending inside insulating layer (2, 3). Insulating layer (2, 3) comprises a gas outlet, wherein the vertical resultant section (82) extends into the gas outlet and comprises opening (83) which opens into insulating layer (2, 3) between the horizontal central plane (200) and lower plane (100).
EFFECT: neutralization of penetration into insulating layers of gas contained in reservoir.
