Hmmmm. Be interesting to know who owns it and who is flying and maintaining it. Statoil terminated the offshore contract with Bristow/Everett (or should that be Everett/Bristow?) back in 2015. The two airframes were relocated to Bristow ops elsewhere and I believe that they are now on the SNS.
It's owned, flown and maintained by Everett.
The previous contract with Statoil was ended when Statoil decided to finish drilling 1 year early because of the falling oil price. The contract with Statoil was an Everett one, on the Everett Tanzania AOC with Bristow having 2 contracts, one for supply of airframes and another for crew. There were actually 2 airframes for O&G and a separate dedicated SAR one fitted with auto hover, twin winch, nite sun and FLIR - the first civil SAR auto hover helicopter in Africa. Both of the O&G aircraft were also winch-capable for back up. The 2 O&G machines ended up on UK offshore, but the SAR machine was moved to Nigeria where it stayed for more than 1 year flying for Bristow Nigeria. The present 139 was flown to Tanzania from UK recently after being purchased by Everett and operating for Statoil from Dar es Salaam on Kenyan AOC. It was flown out by Everett Head of Flight Operations
