Is there any reason to suppose this is more than the entrepreneurial actions of a single company?  Why suppose any official Norwegian involvement?
According to this page the Norwegian state doesn't own any shares in this company. We are no talking about Statoil or hydro here, where the state owns 70%(link) (select share, then shareholders(top 20)) and 43%(link).
The company in question, DNO (Det Norske Oljeselskap) has no Norwegian state ownership, this is purely the entrepreneurial actions of a single company.
