Question 66 ONC04 - Mate of LT 500-1600 GRT

The Correct Answer is C **Why Option C ("Replace the hose") is correct:** When a leak develops in a fuel hose during bunkering (taking on fuel), the immediate action is to stop the operation. Before resuming pumping, the system component that failed (the hose) must be fully restored to a safe and reliable condition. Fuel hoses, especially those used for large-scale operations, are subject to high pressure and carry flammable materials. Replacing the damaged hose ensures that the entire pressure boundary is sound and meets all required safety and environmental standards, eliminating the risk of the leak recurring under pressure. This is the only acceptable permanent solution for damage to critical high-pressure, hazardous material transfer equipment. **Why the other options are incorrect:** * **A) Notify the terminal superintendent:** While communication is important and the terminal/dock safety staff should likely be informed of the incident, simply notifying them does not solve the underlying mechanical and safety problem. You cannot resume pumping until the integrity of the transfer system is secured. * **B) Place a large drip pan under the leak and plug the scuppers:** These actions are essential for pollution mitigation *while* the leak is happening and during cleanup, but they are not a substitute for repairing the breach in the transfer line itself. Placing a drip pan and plugging scuppers does not allow you to safely resume pumping high-pressure fuel. * **D) Repair the hose with a patch:** Patching a high-pressure hose used for transferring flammable liquids is an unacceptable and inherently unsafe temporary repair. Patches are likely to fail under the operational pressure (or when subjected to strain/movement), leading to a catastrophic release of fuel, creating a severe fire and pollution hazard. International safety regulations and best practices mandate replacing (not patching) critical transfer hoses.
