Arrangement for a tank (11) for transport of environmentally harmful liquids in vessels, pipes (16) being connected to the tank for loading or unloading of the liquid (21) as well as for inert gas treatment of remaining air. In order to avoid spillage to the environment in the event of running aground, said pipes (16) are provided with valve members which make it possible to screen off the tank space from the surrounding atmosphere. Moreover, vacuum pump members (17) are arranged for reducing the internal pressure of the tank, until this pressure falls below the surrounding atmospheric pressure. |
