Abstract

An exhaust conduit for a cargo vessel. The exhaust conduit is a flexible conduit with a first upstream opening adapted to engage with an exhaust structure and a second downstream opening for exhausted air. The exhaust conduit is inflatable due to the passage of exhausted air and the downstream opening is of smaller cross-sectional area than the upstream opening. The downstream opening is of adjustable cross-sectional area. In a system for fumigating a RORO vessel, the inflatable exhaust is inflatable to a height exceeding the height of the accomodation block. In a method of fumigating a RORO vessel, the method includes providing a temporary flexible exhaust for exhausting fumigant from the cargo area, and/or providing an inflatable exhaust for exhausting fumigant from the cargo area.

Abstract

A methods and systems of fumigating a vessel include delivering fumigant to a cargo area of the vessel. In particular, the vessel may be a roll-on/roll-off vessel. In such a system, an air pressure system is provided for maintaining a selected minimum pressure differential between a selected area of the vessel above the cargo area and the cargo area, such that pressure of the selected area is greater than the cargo area. A control system may maintain the pressure differential.
