System and method for fumigating a vessel with exhaust

An exhaust conduit for a cargo vessel, the exhaust conduit comprising a flexible conduit having a first upstream opening adapted to engage with an exhaust structure and a second downstream opening for an exhausted air, wherein the exhaust conduit is inflatable due to the passage of exhausted air, and wherein the downstream opening has a cross-sectional area which is at least one of (i) smaller than the first opening or (ii) adjustable.

A system for fumigating a roll-on/roll-off (RORO) vessel, the system being ancillary to the vessel and comprising:

• a fumigant delivery system configured to deliver a fumigant to a cargo area of the vessel;
• and
• a temporary flexible exhaust configured to assist with a removal of the fumigant from the cargo area, wherein the temporarily flexible exhaust has first and second openings, and wherein the second opening has a cross-sectional area that is smaller than the first opening.

A system for fumigating a roll-on/roll-off (RORO) vessel that has a cargo area and an accomodation block, the system being ancillary to the vessel and comprising:

• a fumigant delivery system configured to deliver a fumigant to the cargo area;
• and an inflatable exhaust configured to assist with a removal of the fumigant from the cargo area, wherein the inflatable exhaust is inflatable to a height that exceeds the height of the accomodation block.

A method for ventilating a roll-on/roll-off (RORO) vessel, the method comprising:

• providing an exhaust for exhausting a fumigant from a cargo area of the vessel, wherein the exhaust is at least one of (i) a temporary flexible exhaust, or (i) an inflatable exhaust.
