ETC says 3605B fuel oil, near Gothenberg.
CEDRE paper says 24684 tons.
But the only Bellona I could find
is a small Swedish produict carrier
IMO 6514376, 2366 grt, 3796 dwt,
so it should not really be in the CTX database.
No other info.
This spill may have been the source of the name of the
Norwegian environmental group, Bellona.
