Deep sea mining: an explainer

The video tutorial explains the extraction and processing of natural gas off the coast of Sarawak, Malaysia. It describes the dimensions and location of the extraction unit, which is anchored offshore. The unit liquefies natural gas by freezing it to -162°C without bringing it ashore. The liquefied natural gas (LNG) is then transported back to land by carrier vessels.

Where is the natural gas extraction unit located?

• Off the coast of Sarawak, Malaysia

• Near the coast of Singapore

• In the Gulf of Thailand

• Off the coast of Vietnam

What are the dimensions of the extraction unit?

• 60 meters wide and 300 meters long

• 50 meters wide and 200 meters long

• 70 meters wide and 350 meters long

• 80 meters wide and 400 meters long

What is the purpose of anchoring the unit at a specific site?

• To pump natural gas into the unit

• To conduct marine research

• To serve as a tourist attraction

• To extract oil

At what temperature is the natural gas liquefied?

• Minus 162 degrees Celsius

• Minus 150 degrees Celsius

• Minus 200 degrees Celsius

• Minus 100 degrees Celsius

How is the liquefied natural gas transported back to land?

• Using trucks

• By helicopters

• Through underwater pipelines

• By carrier vessels
