Since the cruise ship tragedy, the public's attention has focused on the search and rescue operation. The Ministry of Transport said rescue professionals carefully considered every operation to make the best choices under the circumstances. Here are some frequently asked questions and the answers provided by professionals:

How was the underwater rescue method determined?

A: Major rescue work includes cutting, righting and diving searches. Salvage experts said the divers' underwater search and rescue was the most efficient immediate plan because cutting into and righting the ship needed more time to prepare, and rescuers had to wait for heavy lifting equipment to arrive. In addition, cutting into the ship and righting it could have harmed survivors.
