The loading pipe connects a cargo tank and a liquefied natural gas loader to allow for flow of fluid between them. The pump columns are formed in a hollow column shape parallel to the loading pipe and connect the cargo tank and a liquefied natural gas unloader to allow for flow of fluid between them. The loading pipe and the pump columns form a triangle tower. The cargo pumps are detachably installed in the hollow of the pump columns.
