How long does it take to stop a tanker?

The Enormous Distance a Tanker Travels Before Stopping

Due to their massive size and weight, supertankers require a significant distance to come to a complete stop. When fully loaded and traveling at normal cruising speed, a supertanker can take nearly 20 minutes to halt. This is due to the immense inertia that needs to be overcome.

However, in emergency situations, specialized procedures can be employed to reduce the stopping distance. By utilizing techniques such as reversing the engines and deploying drag chutes, the stopping time can be shortened to approximately 14 minutes.

Factors Influencing Stopping Distance

Several factors contribute to the extended stopping distance of supertankers:

• Mass: Supertankers have enormous mass, which makes it challenging to decelerate quickly.
• Speed: The faster a tanker is traveling, the greater the distance required to stop.
• Drag: The hydrodynamic drag of water acting on the tanker’s hull slows down its progress.
• Engine Power: The power of the tanker’s engines is a crucial factor in overcoming inertia.

Emergency Procedures

In emergencies, the following procedures can be implemented to reduce the stopping time:

• Engine Reversal: The tanker’s engines are reversed, creating a force that opposes the forward motion.
• Drag Chutes: Parachute-like devices are deployed from the stern of the tanker, increasing drag and slowing down the vessel.
• Rudder Adjustment: The tanker’s rudder is adjusted to create a turning force that helps to dissipate energy.

Conclusion

The extended stopping distance of supertankers highlights the challenges of navigating these massive vessels safely. The use of emergency procedures and careful planning is essential to prevent accidents and ensure the safe operation of these maritime giants.
