BASF / Wintershall, i.e. the German company behind it, has already
announced they will be expecting compensation for the certification blocking.
So far only petty change is being mentioned, but this could go a lot higher especially if their investment in and expected returns from Severneftegazprom are considered. And based on past similar cases, including ones that involved Wintershall, we'll likely be talking full compensation and potential figures of several dozen billion Euro. Might take a while though.
There's a good reason why the German government has been avoiding this kind of interference so far despite the rather extreme pressure from the Americans.
