According to Semco, this marks the completion of a major conversion, expected to be completed today.

“The heavy lifting marks the final and intense part of the project, where the modules are to be installed and hooked up on the rig. Combined with additional modifications of the rig performed simultaneously with the module construction, the former jack-up rig can now be approved and used as a hotel rig,” Semco informed.

The accommodation module has 147 chambers and is now getting ready for the final installation, only eight months after the order was placed in December 2015.

The module was built and outfitted by Semco and its partner Energomontaz-Pólnoc from Poland and was loaded onto a barge heading to Denmark last week.

According to Semco Maritime Vice President Nikolaj Vejlgaard, the company had never built an accommodation block this size before.

The Maersk Guardian which was built in 1986 was designed for year-round operations in the North Sea, and until now, the rig has only been used for drilling. However as of September 2016, it is expected to start a new contract with Maersk Oil as a floating hotel for offshore workers.

Under the agreement, Maersk Oil will use the Maersk Guardian rig in the Danish sector of the North Sea.

The contract will have a duration of five years, with two one-year options, and has been valued at approximately US$142 million (£108.58 million)
