Question 1 of 27070

The most critical time for preventing an accidental oil spill during bunkering, is when the __________.

🔍 Key Concepts

• Bunkering operations sequence: start, steady transfer, topping off, and completion • How tank levels, pressure, and overflow risk change during different stages of bunkering • Typical causes of overflows and deck spills in fuel transfer operations

💭 Think About

• At which stage is there the highest risk of overfilling or sudden overflow due to small remaining tank capacity? • When do operators usually need the most careful monitoring and communication between ship and shore or barge? • Which step involves the finest control of valves and flow rate rather than just connecting or disconnecting equipment?

✅ Before You Answer

• Identify when the tank ullage (empty space) is smallest and overflow risk is greatest • Consider during which choice a small mistake in valve handling can quickly cause a spill • Think about when continuous sounding/level checks and slow-down of pumping rate are most critical
