When bunkering is complete, which is the correct procedure concerning the bunker hoses?

The proper procedure for handling bunker hoses after bunkering is to drain them, blank them off, and store them securely. This practice is crucial for several reasons. First, draining the hoses ensures that any residual fuel is removed, minimizing the risk of spills and leaks during the storage process. Properly blanking off the hoses is essential for preventing contamination and evaporation of the remaining fuel in the hose, as well as protecting the hose fittings from dirt and moisture. Lastly, securely storing the hoses helps to protect them from potential damage, wear, or environmental exposure, which can affect their future use.

The other options do not align with best practices for ensuring safety, operational integrity, and environmental protection. For example, stowing hoses vertically might not be practical or effective in preventing leaks. Cleaning them with a degreaser or hot soapy water does not address the immediate need to remove residual fuel and may introduce additional substances that could contaminate the hoses or cause other issues. Proper draining, blanking, and secure storage is the industry-standard practice that effectively manages these risks.
