Italian shipbuilder Fincantieri has added to its orderbook in a €300m ($332m) deal with French line Ponant.

The company has contracted two 230-passenger luxury expedition cruise vessels, with one option attached.

The order is subject to the finalisation of technical and financial conditions.

The yard group has built four ships for Ponant before, delivered in 2010, 2011, 2013 and 2015.
