SECONDARY BARRIER IN THE LIQUEFIED GAS TANK AND INSULATION BARRIER WITH A SAME

摘要

PURPOSE: A secondary barrier of a liquid cargo hold and an insulation wall of a liquid cargo hold with the same are provided to reduce time required to make a secondary barrier by making the secondary barrier of a cargo hold with a welding method. CONSTITUTION: A secondary barrier of a liquid cargo hold comprises a main panel, a first connecting panel(22), a second connecting panel(24), and corrugations(26a,26b). The main panel is installed in secondary insulation panels(1) and primary insulation panels(3). The secondary insulation panels are adjacently arranged at a predetermined gap. The first connecting panel covers the gap of the secondary insulation panels. The second insulation panel is installed at a crossed point formed by the separation of the secondary insulation panels. The corrugations connect points where the main panel and first and second connecting panels are met each other.
