Which tanker discharge pattern would be the safest and most efficient?

A Start pumping from midships and then work forward and aft simultaneously as the midships tank is emptied
B Start pumping from forward, midships, and aft with the discharge distributed equally among the tanks
C Empty the forward tanks and start working aft, emptying each tank in sequence
D Start discharging with most of the discharge coming from forward, but include some from midships and after tanks
AI Explanation

The correct answer is D) Start discharging with most of the discharge coming from forward, but include some from midships and after tanks. This is the safest and most efficient approach because it helps maintain the vessel's stability and trim throughout the discharge process. Discharging primarily from the forward tanks initially helps maintain the proper trim, while including some discharge from the midships and aft tanks prevents the vessel from becoming excessively trimmed by the head. This balanced approach helps ensure the vessel remains stable and safely navigable during the entire discharge operation. The other options are less desirable as they could lead to excessive trim or instability at various stages of the discharge. For example, option C) of emptying the forward tanks first and then working aft could result in the vessel becoming excessively trimmed by the head, which could compromise its maneuverability and safety.
