The ship, MV Wakashio, owned by Nagashiki Shipping and operated by Mitsui OSK Lines Ltd, ran onto the reef on July 25, and the resulting oil leak has raised fears of a major ecological crisis for the Indian Ocean island.

Having already declared a state of emergency, Mauritius Prime Minister Pravind Jugnauth said the ship has now stopped leaking oil, but the island nation must still prepare for “a worst-case scenario”.

“We will do our utmost towards resolving the situation quickly,” Mitsui OSK said in a statement on Tuesday, adding that it doubted whether the incident would have a large enough impact on its earnings to warrant issuing a disclosure notice to investors.

The company said it has sent six employees to the site was considering sending more, along with transport supplies. The deployed staff were tested for coronavirus before being sent.

The International Maritime Organisation (IMO) said it had joined international efforts to help Mauritius tackle the oil spill by providing technical advice and coordinating the response.

UN agencies and other international organisations were also mobilising environmental and oil spill experts.
