Shetlands




As with many of my posts, this one is very dated and things have moved on a lot since 2001!

Situated some 200 miles north of Aberdeen the Shetland Islands have played a strategically important role in the development of the northern North Sea oil fields.
As the oil companies ventured ever further North in their search for oil deposits so it soon became obvious that the helicopters being used at the time would be stretched to their limits if flying from the Scottish mainland.

As can be seen from this map of the northern North Sea oil fields the Magnus field is approximately 300 miles from Aberdeen airport and aircraft such as the S61 and Puma would not have been able to fly this leg in one go. It soon became clear that it would be to great advantage to set up a base on the Shetland Islands and Sumburgh was chosen as it was already handling oil support helicopters operated by British Airways Helicopters.





The first Bristow aircraft to operate from Sumburgh was probably a Wessex in 1972 but in 1973 a number of S61s joined the base and as can be seen from the photo Pumas and Bell 212s ( this one in Okanagan colours) were also used.





Busy day at Sumburgh circa 1978/79.




The Bristow hangar is the one with the blue roof and the terminal is on the left of the picture. As the operation rapidly expanded, hangars and accommodation had to be provided to keep up and at The Sumburgh Hotel an extension block was added at the rear of the hotel which perfectly blended in with the existing architecture. I think not!
Houses were also built in an effort to persuade personnel to take on the Shetland climate which can be bleak and majestic at the same time with long daylight hours in the Summer and seemingly longer hours of darkness during Winter months.







Taken around 1975 it is interesting to compare this picture with the one above to appreciate the level of development that was required to keep up with the North Sea oil boom.




The airport terminal has provided facilities second to none but from its conception the helicopter operators and oil companies had felt they were being forced to take on an expensive option and Bristows would have probably preferred to operate its own facilities.






Sumburgh has lost all its commercial helicopter operations with various reasons being given. The arrival of longer range aircraft such as the Chinook and Super Puma meant that most of the rig flights could be operated directly from Aberdeen but when Shell finally pulled out and joined a consortium operating out of SCATSTA one of the reasons given was the number of bad weather days averaging 26 compared to SCATSTA's 4.




The above picture is of S61 G-BCLC which is operated on behalf of HM Coastguard, this being the standby machine with G-BDOC in the hangar whilst I was surveying it prior to it undergoing an avionic update at Redhill in 2001. These are the only Bristow aircraft based at Sumburgh at the present time.

The move away from Sumburgh started around 1979 with Chevron operating flights out of Unst initially using it as a staging post as no hangars were available. As the hangar and other facilities came on line so aircraft were based there on a permanent basis.





A couple of S61s in the Unst hangar. I think it can safely be assumed that Unst was the UK's most northern airfield and it must have felt a long way from civilisation in the early days.






Unst Flight Operations where flights to the numerous offshore installations were planned. The notice board contained details of rig positions and movements because many of the offshore helipads were constantly on the move.




Another advantage of short helicopter flights is the cost saving as a cheaper seat-mile aircraft can be used to fly the majority of the journey. This Brymon Airways Dash 8 was probably on the Aberdeen - Unst run.





A muddy G-BFRI at Unst. "It was on the helideck of one of the Ninian platforms when the "mud" pipe to the wellhead burst. The cabin attendant was outside the aircraft when the pipe went and he arrived back at Unst looking like the original flower grader!"











When construction of the Sullom Voe oil terminal was commenced a small airfield was constructed to transport construction workers to and from the UK mainland.
In the mid nineties oil companies looked to SCATSTA as a possible location to consolidate Shetland Islands oil support operations. They moved from Unst and Shell joined them from Sumburgh in 1999 after a 30 year association with the airport.
Prior to Shell moving to SCATSTA the airfield was given a $3.5 million facelift including runway reinforcement, navaid upgrade and expansion of the terminal facilities.
As of mid 2000 the SCATSTA consortium was operating around 5 Super Pumas ( Tigers).
