....Shell citing the EC155 Sea State issue and added expense of hiring-in 139s as factor for curtailing contract (plus the fact that CHC were virtually throwing the 139s at them might have helped)
Sea State issue came about due to CAP1145, which came about as a direct result of CHC crashing off Sumburgh......
No wonder they say you have to have a sense of humour in this job ;-)
Only Shell employees have been officially informed, Shell probably delaying formal notification until May so 3-months notice would give them a month's overlap.
Crazy situation to be in but apparently such corporate practice does not occur or at least that was what the oil companies told the CAA
