The photographed was featured in Popular Mechanics magazine, in March 1980.

"Dunlin-A being towed onto site. Intersub 3 was there to cut the tow chains after she was set in place on the bottom.

The tow was a big thing at the time due to her weight."
The Dunlin oilfield is situated 195 km northeast of Lerwick. Originally operated by Shell it was sold to Fairfield Energy in 2008.
The total sub-structure weight was 229,000 tonnes. 
In May 2015, Fairfield Energy announced plans to decommission Dunlin Alpha.
