An oil and water discharge tube is provided which may be inside or outside the water tube. If inside, then one end of the membrane is connected to the air tube and the other end to the ballast tube to form a gallery for reception of the overspill. If outside, then one end of the membrane is connected to the air tube and the other end to the discharge tube to form the gallery. Pumps may be provided in the discharge tube to remove overspill from the gallery.
