This was a risky connection to begin with - whether SAS would be in the same alliance or not (it never was).
I’ll assume based on tomorrow’s schedule, that you’re scheduled to arrive 7:15 and are connecting on BT132 (codeshared by SK) departing 8:15. That’s not an impossible connection, but the problem is the next direct flight departs at 20:00.
An easier option would’ve been SIN-HEL-VNO.
