Norwegian offshore vessel giant DOF Group is facing another attempt by rebel shareholders to replace its board as a key decision on its possible bankruptcy approaches.

Directors of the Oslo-listed company, which is trying to forge an equity-swap deal to reduce $2.25bn of debt, have received an email from a group of investors demanding another extraordinary general meeting.

This is little more than a month after a rebel group ousted the board that had negotiated a deal with banks to save 4% of shareholders’ equity.
