  4. Basic philosophy of power turbines • Long service life / 100,000 hours average design life • For gas generator servicing, power turbine remains in place - alignment is • not disturbed • “Industrial” type construction • Infinite life hydrodynamic bearings • Overhung rotor design - no hot bearings • Cooper pioneered the aeroderivative gas turbine concept • It is now the standard prime mover concept for oil and gas production and • pipeline power 26/03/99 009666/02 PPT
