What effect will transferring fuel oil from No.1P double bottom to No.3P double bottom have on the trim of a vessel?

🔍 Key Concepts

• How shifting a weight longitudinally (forward or aft) affects trim • Difference between trim (difference between forward and after draft) and mean draft (average of forward and after drafts) • Effect on drafts when a weight is moved aft vs. forward

💭 Think About

• Visualize the ship from the side. Is No.1P double bottom usually located more forward or more aft than No.3P? • If you move fuel from No.1P to No.3P, are you moving weight toward the bow or toward the stern? • When weight moves in that direction, which end of the ship will tend to go deeper in the water, and which draft (forward or aft) will change accordingly?

✅ Before You Answer

• Confirm whether the total weight of the vessel changes when transferring fuel internally (no fuel added or discharged). • Decide which way the ship will trim (by the bow or by the stern) when weight is moved from tank 1P to 3P. • From that trim direction, determine which draft (forward or aft) will increase and which will decrease, and what happens to the mean draft.
