Gdynia Shipyard Group developed stowable ro-ro (sto-ro, or: ro-lo) ships of 8222 class - primary for paper roll
and palletized wood pulp transport, but also for boxes - 716 TEU. (L = 157,50 m, B = 25,60 m, H = 16,30 m).
Such versatile ships were ordered by consortium Palkkiyhtyma OY (Finland) and B&N Nordsjöfrakt (Sweden)
and have highest ice class. Three vessels were delivered as initially planned:

In year 2006 all three ships were lengthened at Blohm+Voss by ca. 20 m, increasing capacity to 759 TEU.
In 2018, the third one was converted by new owner into power station vessel.

There was also fourth vessel ordered by consortium, but contract was cancelled, while under construction.
The launched, incomplete hull was later sold to Dutch Wagenborg and delivered in June 2004 as:
