S61-S92. Being a bit pedantic but I think that picture of GTIGR was taken in June 1981. It was a BNOC or Britoil contract to the Discoverer 534, a drilling ship. The direct route took us directly over the island of Foula and there was a Godawful row when we did it on a Sunday.
On August 18th I took GTIGR down to Yarmouth to do the Southern North Sea as the Wessexs had been grounded following their fatal crash.
