Borr Drilling, the start-up of Norwegian investor Tor Olav Troim, will be applying for a listing on the Oslo Stock Exchange in the second half of this month.

The move is partly aimed at preparing the company for further asset purchases or mergers and acquisitions, it says.

The Olso-listing will not involve an initial public offering (IPO) but a listing of its 315 million shares valued at about $1.5bn.
