A luxury cruise ship that ran aground this week in a remote Greenland location with 206 people on board has been pulled free by a trawler, a spokesperson for Denmark's armed forces said Thursday.

The Ocean Explorer cruise vessel had since Monday been stuck in mud and silt in the Alpefjord national park, some 1,400 km (870 miles) northeast of Greenland's capital Nuuk.

Denmark's armed forces and the cruise ship's operator have said there were no injuries among the passengers or crew.

The cruise ship ran aground above the Arctic Circle Monday in the Northeast Greenland National Park, which is almost as much land as France and Spain combined, and approximately 80% is permanently covered by an ice sheet. Alpefjord sits about 240 kilometers (149 miles) away from the closest settlement, Ittoqqortoormiit, which itself is nearly 1,400 kilometers (870 miles) from the country’s capital, Nuuk.

The Greenland Nature Institute’s fisheries research vessel Tarajoq attempted to pull the Ocean Explorer free at high tide early Wednesday morning.

“Unfortunately, the attempt was not successful,” said the Danish Joint Arctic Command, which was coordinating the operation to free the cruise ship.

The cruise ship is operated by Australia-based Aurora Expeditions and has passengers from Australia, New Zealand, South Korea, the United Kingdom and the United States. It has an inverted bow, shaped like the one on a submarine. It has 77 cabins, 151 passenger beds and 99 beds for crew, and several restaurants.

Australian newspaper the Sydney Morning Herald quoted a retired couple from Australia, Steven Fraser and Gina Hill.

On board there are “a lot of wealthy older people” and “everyone’s in good spirits. It’s a little bit frustrating, but we are in a beautiful part of the world,” Fraser was quoted as saying by the daily.

“We do have a couple of cases of COVID, but there’s a doctor on board,” he told the daily, adding he himself had come down with COVID-19 on the ship.
