Canada's BC Ferries has continued its green fleet renewal with a new order in Poland.

The company said it had picked Remontowa Shipbuilding of Gdansk to build another CAD 92.3m ($70m) LNG-fuelled passenger vessel for delivery in 2022.

It will serve the Southern Gulf Islands and is identical to the three Salish Class vessels built by Remontowa for BC Ferries in 2016.
