Finnish PHD thesis says ship was loaded with 37,000 T of crude,
grounded near Porvoo Lighthouse, 570 tons spilled, lots of ice.
Cedre has this spill at 700T.
IOPCF says 600 to 700 tons..
How does a ship ground near a lighthouse?
We need circumstances, machinery problems????
This ship was involved in a 1979 grounding at ventspils.
