Q

Why is a VLCC (100,000 DWT+) with a 30,000 Shaft Horsepower Steam Turbine slow to respond to engine movements, and has less stopping power than normal ships?

🔍 Key Concepts

• Power-to-weight ratio and how it affects acceleration and stopping distance • Characteristics of large tankers (VLCCs): very high displacement and inertia • Relationship between installed horsepower and ship size/mass

💭 Think About

• Compare the ship’s enormous deadweight (100,000 DWT+) to the 30,000 SHP: is that a lot of power or a little, relative to its mass? • Think about which factor would make a ship sluggish in speed changes: more power per ton, or less power per ton? • Which choice directly relates to how quickly you can overcome the momentum of a very heavy ship?

✅ Before You Answer

• Identify which options refer to power-to-weight ratio rather than just size of propeller • Ask: For stopping and acceleration, is higher or lower power per ton better? • Eliminate any answer that doesn’t clearly connect to the idea of insufficient power for the ship’s mass/inertia
