Mining Firm Buys Ex-Cruise Ship for Greenland Worker Housing

Ex-Soviet Ferry Turned Cruise Ship Gets New Role as Floating Workforce Camp

A U.S.-listed mining and exploration company has purchased a veteran polar cruise vessel to serve as accommodation for its rare earth minerals project in southern Greenland. According to a report by The Maritime Executive, Critical Metals Corp. has acquired the expedition cruise ship Ocean Endeavour for €7.5 million ($8.5 million), with plans to house roughly 300 personnel working on its Tanbreez project near Qaqortoq.

From Baltic Ferry to Arctic Workforce Hub

The Ocean Endeavour has a long and varied service history. Built in Poland in 1982, the vessel began life as the Soviet passenger ferry Konstantin Simonov, operating in the Baltic Sea. It changed hands multiple times over the decades, was converted into a cruise ship in the early 2000s, briefly ran for an Israeli operator, and was later refitted in 2015 for polar expedition cruising.

Most recently the 12,900 gross ton, 137-meter ship was owned by SunStone Marine Group, which chartered it out to several parties. Earlier this year the Danish Defence used the vessel to accommodate Danish and NATO troops taking part in the Arctic Endurance exercise, giving the ship added visibility before it went up for sale last month.

The vessel can carry 190 passengers along with a crew and staff complement of 124, and its ice-strengthened construction and proven track record in both Arctic and Antarctic waters were cited by Critical Metals as key reasons for the purchase.

Easing Pressure on Local Infrastructure

Critical Metals, which took a controlling stake in the Tanbreez project in 2024, describes the site as one of the world’s largest undeveloped rare earth deposits, with heavy rare earth elements considered essential for defense systems, clean energy technology, and advanced electronics.

By mooring the Ocean Endeavour alongside the project site, the company intends to provide flexible, self-contained housing for up to 300 workers without straining the limited hotel and tourism capacity in Qaqortoq and the surrounding region. Company Chairman Tony Sage said the ship gives the firm “a flexible, proven platform” to support its workforce, streamline logistics, and improve operational efficiency as development activities continue. He also noted the vessel strengthens the company’s ability to carry out its long-term growth plans while prioritizing safety in a region with sensitive infrastructure limitations.

Why It Matters for the Maritime Industry

The deal highlights a growing trend of repurposing decommissioned or underused passenger vessels as accommodation platforms for remote industrial and defense operations, particularly in areas where land-based housing is scarce or environmentally sensitive to develop. Greenland’s expanding role in the global rare earth supply chain, combined with limited local infrastructure, appears to be driving demand for these floating housing solutions.

For ship owners and managers, the transaction also underscores the extended commercial life that well-maintained, ice-strengthened vessels can achieve outside their original passenger trade — provided their structural and mechanical condition is properly verified before changing hands.

A Note on Vessel Condition Ahead of Repurposing

While the source report does not detail any survey or condition assessment tied to this transaction, projects that convert vessels to new uses — whether floating accommodation, storage, or offshore support — typically benefit from independent condition and pre-purchase surveys to confirm structural integrity, machinery status, and compliance before entering long-term service in remote or harsh environments. Apeks Marine provides these types of pre-purchase and condition survey services to ship owners and operators evaluating vessels for repositioning or repurposing.
