Per Saevik-backed ferry company Fjord1 has been approved for a full Oslo Stock Exchange listing.
The bourse's board has said the shipowner must fix a date to list no later than 25 September.
TradeWinds reported earlier this year that the company joined the Oslo Merkur Market en route to a full listing, which was expected to be secured in June.
Saevik, who has previously listed a series of OSV companies including Havila Shipping and shipbuilder Havyard, cut his stake from 67% to 33% via a share issue this year.
Fjord1 was founded in 1858 and had 1,280 employees at the end of 2016.
