Towing vessel fire protection regulations require that all fuel tank vent pipes comply with all of the following provisions EXCEPT that the vent _______________.

AI Explanation
The correct answer is A. Towing vessel fire protection regulations do not require that the fuel tank vent pipe have a positive-acting shut-off valve to prevent water from entering the tank in heavy weather. The other provisions - having a 30-by-30 corrosion resistant flame screen, connecting to the highest point of the tank, and discharging on a weather deck through a U-shaped 180 degree pipe bend - are all required by the regulations. However, a positive-acting shut-off valve is not a mandatory requirement for the fuel tank vent pipe system.
