🔍 Key Concepts

• Kinetic energy on impact increases with both displacement (DWT) and speed • Rule‑of‑thumb relationships between ship size and maximum berthing (docking) speed • How small changes in speed cause large changes in impact force on fenders and quay

💭 Think About

• Compare how much kinetic energy changes if you double the docking speed. How does that affect the safety margin for a 120,000 DWT ship? • Think about typical berthing speeds used by pilots for very large bulk carriers: are they closer to tenths of a foot per second, or closer to one foot per second? • Eliminate any option that would likely create excessive fender loads for such a large vessel by thinking about how a small increase in speed greatly increases impact energy.

✅ Before You Answer

• Estimate which speed range would keep impact energy low enough for a 120,000 DWT ship: well below 1 ft/s, or closer to 1 ft/s? • Check which choice best matches conservative pilotage practice for very large ships coming alongside in normal conditions (not emergencies). • Verify that the chosen speed leaves a large safety margin for fender strength and mooring line loads when something unexpected happens during the final meters before contact.
