Hmm, maybe they keep at least the superstructure above water, for cannibalizing.
I wonder why the situation worsened. The watertight compartments are supposed to avoid that.
Compartmentalisation does not help much, if rocks tear open the side of the hull. Though whta exactly happened remains to be seen.
from you link to maritime bulletin:
Norwegian frigate damaged in collision with Greek Aframax tanker, crew evacuated Update frigate to blame
Greek Aframax tanker SOLA TS collided with Norway Navy frigate HNOMS HELGE INGSTAD in the morning Nov 8, probably around 0300 UTC, in North sea north of Bergen, Norway. Laden tanker left Sture Terminal shortly before collision. According to Norway media reports, frigate sustained heavy damages, water ingress, probably in danger of sinking, all 137 crew evacuated, 7 were slightly injured. Tanker said not to suffer serious damages, as of 0530 UTC she was near collision site, moving in northern direction at dead slow speed, escorted by tug. Salvage under way, many tugs and SAR ships in collision area.
Update: Frigate understood to sustain stb bow hull breach with massive water ingress, she’s said to develop heavy bow tilt.
Update: 0700 UTC – according to latest reports frigate was taken to shallow waters to avoid sinking, water ingress is incontrollable.
Comment: Again, laden massive cargo ship collided with Navy frigate, similar to accidents which occurred with USA Nay frigates in Japan and off Singapore, recently. Understood frigate was hit by tanker, it’s like feather-weight boxer being hit by super weight clumsy, slow moving giant boxer. Whatever the situation and ships positions were according to COLREG, Navy is the main culprit. Aframax tanker in full load is restricted in maneuverability by definition, while frigate, by definition, is speedy maneuverable vehicle, supposedly always ready for dangerous situation, manned by a numerous crew.

comment says that the firgate FUBARed navigation, the AFRAMAX is several magnitudes heavier and bigger in size. Hoe do you miss that one and get hit by it?
