Transport of contents of a vessel (2) such as a production vessel or storage vessel to a handling location without exposing the contents to the environment in a preferably disposable transport container (10) having an inlet port (14) provided with a second door (16). The contents are released to the transport containers through an outlet port (18) having a first door (20) and which is located on the vessel. By rotational engagement, the respective ports (14, 18) are couplable on the one hand and the respective doors (16, 20) are couplable on the other hand so that when the ports are coupled and the doors are coupled, the coupled door combination can be displaced to permit communication between transport container (10) and vessel (2). The surfaces of the doors which in the uncoupled state of the transport container and the vessel are exposed to the environment are sealingly engaged together to prevent ingress of material therebetween. When transfer of contents of the vessel into the transport container (10) is to be terminated, communication between the transport container (10) and the vessel (2) is closed off and the doors (16, 20) are disengaged to leave the ports closed by respective doors. |
