These mechanical system work either by extraction from the bottom of the hold by means of exhaust ventilation or with natural exhaust generated by a supply ventilator. The air flow on open top ships is affected by air entering through the open holds. Due to open structure, gases lighter than air can disappear even without mechanical ventilation. 3. Bilge pumps --- Open top container ships are equivalent with higher capacity bilge pumps in order to remove green water shipped in seagoing condition an...
