Sikorsky has introduced a software fix for its S-92 that it says will address a 4R vibration some pilots have experienced at high cruise speeds. The company has already retrofitted new active vibration control software to some of the fleet.
CHC Helikopter Service
With North Sea competition investing in the EC 225, Super Puma Mk 2 and S-92, is there still a role for the Sikorsky S-61N? The workhorse has been providing sterling service for more than 40 years, but the oil majors regard it–as a people-carrier at least–as obsolescent hardware.
In 1999, in a wide-ranging re-alignment of North Sea helicopter assets, Canadian Helicopter (CHC) bought Norway’s Helikopter Service, together with Brintel and Bond in the UK. The company was soon relaunched as CHC Scotia.
It was bound to happen eventually. British International (BI), the company that rose from the ashes of what was once North Sea operator British International Helicopters, is back on the energy-support map. This month it will start flying Shell workers out to an economically promising but politically controversial gas field known as Corrib, 62 miles off the northwestern coast of the county of Donegal in the Republic of Ireland.
