Norway's Solstad Offshore has logged its highest operating profit since it merged with three other shipowners four years ago.

The Oslo-listed company's Ebitda rose to NOK 500m ($55m) in the three months to 30 September, from NOK 395m in the same period of 2020, in recovering offshore support vessel markets.

This equals the best figure since Solstad merged with Rem Offshore, Farstad Shipping and John Fredriksen's Deep Sea Supply following the last offshore vessel crash in 2016 and 2017.
