Tor Olav Troim-backed Borr Drilling is working on financing worth a total of $660m as its liquidity needs increase.
The Oslo-listed rig company has so far this year secured additional cash consisting of a $100m revolving credit facility and a $60m credit line for issuance of guarantees with two international commercial banks.
These mature in May 2020.
It has also released another $25m from an existing $200m facility that had previously been restricted.
