A system for reduction a system for reduction of emissions from volatile liquid cargo within a pipe work supplying cargo into a cargo tank, the pipe work including an upper pipe segment (1.1) and a lower pipe segment in the form of a mainly vertical drop pipe (1.4) terminating near the bottom of the cargo tank, and having means controlling the pressure within the pipe work during loading. According to the present invention a flow restricting device is installed in the upper pipe segment (1.1) in front of the drop pipe (1.4) so as to assure positive pressure throughout the upper pipe segment, and the drop pipe (1.4) is provided with a perforated pressure equalization pipe (1.7) and a free flow dampening device (1.6) surrounding pressure equalization pipe, the upper portion of the drop pipe above the upper pipe segment (1.1) is provided with a top section (1.5) so as to form a gas collecting as well as pressure monitoring and controlling volume communicating with the pressure equalization pipe of emissions from volatile liquid cargo |
