Dynagas LNG Partners, a US-listed owner of six LNG carriers, has filed papers preparing for the possible sale of shares or other securities in the company worth more than $400m.

That includes the entire 42.4% stake held in the firm by Procopiou family-controlled Dynagas Holding, which has a current market value of close to $60m.

According to the shelf registration submitted to the US Securities and Exchange Commission on Thursday, Dynagas LNG Partners said it “may from time to time, in one or more offerings” sell securities worth up to $350m.
