Question 3234 Deck General

The correct answer is A) Acts as an accumulator. The air receiver in the compressed air system on a MODU (Mobile Offshore Drilling Unit) functions as an accumulator. It stores compressed air and helps to maintain a steady air pressure in the system, which is essential for the proper operation of pneumatic equipment and tools on the MODU. The air receiver smooths out any fluctuations in air pressure, ensuring a consistent supply of compressed air to the various systems that depend on it. The other options are incorrect because: B) Provides overpressure protection is the function of a pressure relief valve, not the air receiver; C) Purifies the air is the role of an air dryer or filter, not the air receiver; and D) Condenses moisture is the function of a moisture separator, not the air receiver.
