1. What is the primary purpose of a pressure relief valve on an
offshore platform system?
A. Increase system pressure
B. Store excess fluid
C. Protect equipment from overpressure
D. Control flow direction
Rationale: Pressure relief valves prevent system failure by releasing
excess pressure.
2. Which lubricant is most commonly used in high-load offshore
rotating equipment?
A. Water-based lubricant
B. Grease with low viscosity
C. Synthetic oil
,D. Diesel fuel
Rationale: Synthetic oils provide stability under high load and
temperature conditions.
3. What is the main function of a centrifugal pump?
A. Compress gas
B. Move fluid using rotational energy
C. Measure pressure
D. Filter contaminants
Rationale: Centrifugal pumps convert rotational energy into fluid flow.
4. What does cavitation in a pump indicate?
A. Excess lubrication
B. Electrical failure
C. Formation of vapor bubbles due to low pressure
D. High fluid viscosity
Rationale: Cavitation occurs when pressure drops below vapor pressure.
5. What is the purpose of a gasket in mechanical joints?
,A. Increase torque
B. Reduce vibration
C. Prevent leakage between surfaces
D. Increase speed
Rationale: Gaskets seal joints to prevent fluid or gas leakage.
6. Which component converts reciprocating motion into rotary
motion?
A. Gearbox
B. Compressor
C. Crankshaft
D. Bearing
Rationale: Crankshafts convert linear motion to rotational motion.
7. What is the function of a heat exchanger?
A. Store fluid
B. Increase pressure
C. Transfer heat between fluids
D. Filter gas
, Rationale: Heat exchangers allow thermal energy transfer without
mixing fluids.
8. Which tool is used to measure shaft alignment?
A. Multimeter
B. Tachometer
C. Dial indicator
D. Pressure gauge
Rationale: Dial indicators measure small deviations in alignment.
9. What is the primary hazard of working with compressed gas
systems?
A. Electrical shock
B. Explosion due to pressure release
C. Noise pollution
D. Low temperature
Rationale: Sudden release of compressed gas can cause explosions.
10. What does API lubrication standard primarily regulate?
