Abstract
Abstract A liner apparatus for a tanker having at least one storage compartment and at least one tubular pipe extending into said compartment for conducting a liquid or gas. The liner apparatus includes an elastomeric, resilient liner contiguous with at least a portion of the storage compartment. A mounting bracket has an opening to receive the pipe therethrough and is suspended from the pipe. A fluid and gas impermeable flexible bladder within the storage compartment has an opening to receive the pipe. The flexible bladder is sealably attached to the mounting bracket, whereby spillage of the liquid or escape of the gas from the bladder will be prevented.
