The British-owned cruise smashed into the protected Raja Ampat National Marine Park, damaging 13,500 square metres of invaluable coral reef.
Caledonian Sky ran aground in one of the most biodiverse marine habitats in the world.
Carrying 102 passengers and 79 crew, the 4,200-tonne liner crashed into the reef at low tide on March 4.
Passengers had just finished a bird-watching tour on Waigeo Island when the devastating event occurred.
The ecosystem’s fragile structural habitat has been destroyed, with the loss of coral genera diversity.
Indonesia’s government is assessing the damage to the Kri Island reef, with plans to seek compensation from the cruise company.
Due to the unique biodiversity of the area, evaluators will recommend compensation of £650-£985 per square metre, a total of £1.05m – £1.58m.
That’s the advice from Ricardo Tapilatu, a marine researcher from the University of Papua who is leading the assessment team.
Mr Tapilatu said: “A tugboat from Sorong city was deployed to help refloat the cruise ship, which is something that shouldn’t have happened because it damaged the reef even worse.
“They should’ve waited for high tide to refloat the vessel.”
Caledonian Sky had set sail from Papau New Guinea on February 25 and was scheduled to arrive in the Philippines on March 14.
MS Caledonian Sky – owned by UK-based tour company Noble Caledonia – said in a statement: “We are working with local experts to understand how we can assist with the regeneration of the reef. We value our relationships around the world with local people and we are sorry to have impacted the local community.
