Norrona was built by Flender Werft in Luebeck if I'm not mistaken!
Designed by FSG and built with extensive engineering support from them. She was originally to be built at FSG but a combination of yard availability, cost (Smyril couldnít fund her in time for the original slot apparently), and politics (Flender needed the work) meant she wasnít.
I am sure if expertise was required FSG would not be found wanting in contracting it in to complete the design.
Which would cost. Donít forget they are trying to get costs down, not increase them.
Also more than a little embarrassing for a business actively advertising its design expertise!
