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.
Claims17
A control system for a roll-on/roll-off (RORO) vessel, the control system comprising a controller configured to:
- receive at least one pressure reading or at least one differential pressure reading from at least one of a selected area of the vessel or a cargo area during a fumigation;
- in response to the at least one reading, control an air delivery to the selected area of the vessel in order to maintain a selected minimum pressure differential between the selected area and the cargo area with a pressure of the selected area being greater than a pressure of the cargo area;
- and
- maintain the selected minimum pressure differential throughout the fumigation and a subsequent exhaust of a fumigant from the cargo area.
A method of pre-configuring a control system which is ancillary to a roll-on/roll-off (RORO) vessel, the method comprising pre-configuring a controller of the ancillary control system such that the controller is configured to:
- receive at least one pressure reading or at least one differential pressure reading from at least one of a selected area of the vessel or a cargo area during a fumigation;
- in response to the at least one reading, control an air delivery to the selected area of the vessel in order to maintain a selected minimum pressure differential between the selected area and the cargo area with a pressure of the selected area being greater than a pressure of the cargo area;
- and
- maintain the selected minimum pressure differential throughout the fumigation and a subsequent exhaust of a fumigant from the cargo area.
A system for fumigating a vessel wherein the system is ancillary to the vessel, the system comprising:
- a fumigant delivery system configured to deliver a fumigant to a cargo area of the vessel;
- and
- an air pressure system configured to maintain a selected minimum pressure differential between a selected area of the vessel above the cargo area and the cargo area, such that a pressure of the selected area is greater than a pressure of the cargo area.
