  • Method and apparatus for Christmas tree condition monitoring
    Patent number: 7967066
    Abstract: A method for monitoring a Christmas tree assembly installed on a subsea hydrocarbon well includes receiving a plurality of parameters associated with the Christmas tree assembly. A health metric for the Christmas tree assembly is determined based on the parameters. A problem condition with the Christmas tree assembly is identified based on the determined health metric.
    Type: Grant
    Filed: May 9, 2008
    Date of Patent: June 28, 2011
    Assignee: FMC Technologies, Inc.

  • Optical sensing system for wellhead equipment
    Patent number: 7845404
    Abstract: A system includes a Christmas tree assembly mounted to a hydrocarbon well, an optical feedthrough module, and a plurality of optical sensors. The optical feedthrough module is operable to communicate through a pressure boundary of the Christmas tree assembly. The plurality of optical sensors is disposed within the Christmas tree assembly for measuring parameters associated with the Christmas tree assembly and is operable to communicate through the optical feedthrough module.
