Tanker Familiarization Emergency and Fire Procedures Questions and Answers 1 — Questions and Answers
Question 1: A fire is detected in the cargo pump room while the vessel is discharging at the terminal. After sounding the alarm, what is the most critical immediate action regarding the emergency systems?
- Manually activate the emergency fire pump.
- Activate the Emergency Shutdown (ESD) system. (Correct answer)
- Release the fixed CO2 system for the pump room.
- Ventilate the pump room to clear smoke and gas.
Correct answer: Activate the Emergency Shutdown (ESD) system.
Activating the Emergency Shutdown (ESD) system is the most critical initial action. This system is designed to stop cargo flow, shut down pumps and compressors, and close manifold valves, thereby isolating the source of fuel for the fire and preventing escalation of the emergency. While starting the fire pump is important, stopping the cargo operation via the ESD is the first priority. Releasing CO2 is a secondary step taken only after the space is confirmed to be evacuated, and ventilation would feed oxygen to the fire.
Question 2: According to SOLAS, what is the primary fixed fire-fighting system required for the cargo tank deck area of a tanker?
- A high-expansion foam system.
- A fixed dry chemical powder system.
- A fixed deck foam system. (Correct answer)
- A fixed water-spraying (deluge) system.
Correct answer: A fixed deck foam system.
SOLAS Chapter II-2 specifies that the cargo tank deck area on tankers must be protected by a fixed deck foam system. This system is designed to blanket the deck and the tops of cargo tanks with foam, effectively smothering a liquid fuel fire by cutting off the oxygen supply and providing a cooling effect.
Question 3: A small cargo spill occurs on the main deck during loading operations. Which of the following actions should be taken FIRST to contain the spill?
- Wash the deck with fire hoses to dilute the cargo.
- Apply foam from a portable extinguisher to the spill.
- Ensure all deck scuppers are securely plugged. (Correct answer)
- Notify the port authority and request assistance.
Correct answer: Ensure all deck scuppers are securely plugged.
The first and most immediate action to contain a deck spill is to ensure all deck scuppers are plugged. This prevents the spilled cargo from escaping overboard and causing marine pollution. Once containment is assured, other actions like stopping the operation and cleaning up the spill can follow.
Question 4: During a fire drill, a scenario involves a fire on the cargo manifold. Which of the following is a critical step the Master or Officer in Charge should consider regarding the vessel's movement?
- Increase speed to create a stronger wind over the deck.
- Maintain course and speed to avoid disrupting traffic.
- Immediately drop anchor to stabilize the vessel.
- Alter course and speed to place the fire on the leeward side. (Correct answer)
Correct answer: Alter course and speed to place the fire on the leeward side.
In the event of a deck fire, the vessel should be maneuvered to minimize the effect of wind on the fire and keep smoke and flames away from the accommodation block and personnel. Altering course to put the fire on the leeward (downwind) side is a standard procedure to aid firefighting efforts and enhance crew safety.
Question 5: What is the minimum frequency for conducting a fire drill for all crew members on a tanker, as required by SOLAS?
- Once every week.
- Once every two weeks.
- Once every month. (Correct answer)
- Once every three months.
Correct answer: Once every month.
SOLAS Chapter III requires that every crew member participate in at least one fire drill every month. If more than 25% of the crew have not participated in a drill on that ship in the previous month, a drill must be held within 24 hours of leaving port.
Question 6: A cargo hose ruptures during a ship-to-ship transfer, spilling oil onto the deck and into the sea. After raising the alarm and stopping the transfer, what is the immediate responsibility of the deck watch?
- Take photos of the incident for the official report.
- Deploy the ship's oil spill containment boom.
- Activate the Shipboard Oil Pollution Emergency Plan (SOPEP). (Correct answer)
- Start cleaning the deck with absorbents.
Correct answer: Activate the Shipboard Oil Pollution Emergency Plan (SOPEP).
In any incident involving an oil spill, the Shipboard Oil Pollution Emergency Plan (SOPEP) must be activated immediately. This plan outlines the specific procedures, reporting requirements, and allocation of duties for responding to the spill. Actions like deploying booms and cleaning the deck are part of the SOPEP response but activating the plan itself is the overarching first step.
