Maximum Operating Condition
Operating condition defined by the operator as the maximum permissible for the system.
NOTE The maximum operating condition can be different for each riser and can be different for different phases of the operation. For example, the maximum operating condition for hydrostatic test might be a one year winter storm, while the maximum operating condition during production might be a 100-year winter storm.
