The paper outlines the operating and maintenance experience of the TYPE H industrial gas turbines on 2 of the platforms in the Greater Ekofisk field on the Norwegian continental shelf.
Traditional preventive maintenance procedures based on elapsed fired hours are discussed. Availability and reliability statistics are presented.
Typical component replacement on inspections is tabulated and comments are given.
Finally the author describes an on line, computer supervised, condition monitoring system which is being used and will help replace traditional preventive maintenance with predictive maintenance.
