Some news reports say the bulk carrier had a propulsion failure. Others say the propulsion failure was with the tugboat. I agree with the latter.
Carrier is initially at, or close to full ahead, rudder amidships. Tugboat is under power, thrusting forward (starboard and facing the carrier's stern). Tug is not in contact with the carrier, or towing its bow away from the marina.
Carrier goes to idle.
Tug goes to idle/stop.
Carrier resumes 3/4 ahead, full right rudder. It doesn`t appear to have bow thrusters and the tug is dead in the water, abutting the starboard bow, so the stern swings back through the moored boats.
I would say that the tug`s propulsion problem caused the accident and its position exacerbated the recovery, but I don`t understand why the carrier decided to power out instead of waiting for another tug.
