Question 989 Deck General

The correct answer is D) readily accessible gastight glands shall be provided. The reason this is the correct answer is that U.S. regulations require cargo pump shafts on tankers that pierce bulkheads to have readily accessible gastight glands. This is to ensure that the integrity of the bulkhead is maintained and prevent the potential release of cargo vapors or liquids from one compartment to another. The other answer choices are incorrect because they do not accurately reflect the regulatory requirement. Compressed air is not required as the primary means of cargo discharge, pressure gauges are not mandated, and continuous suction ventilation is not specified in the regulations for this particular situation.
