Tango123 DanCopters excellent service with 1 or 2 aircraft in Den Helder would not qualifiy them well to take on the running of an operation in the Delta if it were not for the technical brilliance of Shell's own personnel in Nigeria, though no doubt with help drafted in from Rotterdam and Brunei. Shell has basically run Bristow's operations in the Delta for 40 years so the management of change will be very smooth.
