The tug that took her from Bremerhaven was the 'De Da', a 1979 built ocean going tug. The 'De Da' was still with the Norway when they stopped for bunkers off Cape Town, she was relieved of her tow for a short while by other tugs whilst she put into Cape Town for bunkers and supplies.

Neither of the tugs in your post are the 'De Da', so maybe they are the one's that took her from Port Kelang?
EDIT: Point of interest, the 'De Da' was the tug that was towing the 'SS Constitution' (sister of the 'SS Independence'), when she sank on her way to the breakers.
