CLEAN : Operation starts to refloat ill fated Italian cruise ship

The video tutorial discusses the first phase, 22 E, focusing on reducing the weight on a platform. Initially, the platform weighed approximately 10,000 tons. Through strategic efforts, around 8,000 tons have been removed, resulting in a current weight of about 2,500 tons. The ship remains on the platform, but with significantly reduced weight.

What does the text imply about the ship's stability on the platform?

What is the current weight of the ship before starting the process?
