DESCRIPTION:



     The COMPUTE FATIGUE LIFE command (for offshore structures) will

abort if member fatigue stress computation positions are not specified in

the FATIGUE MEMBER command.  The following example illustrates a case

when the abort would occur:



     FATIGUE MEMBER DATA

      2200010 SCF VAR USER -

      START SAD AX 6.0 IPB 0.0 OPB 7.5 CRO AX 7.3 IPB 2.4 OPB 0.0 -

      END SAD AX 5.5 IPB 0.0 OPB 8.0 CRO AX 8.0 IPB 2.5 OPB 0.0





     COMPUTE FATIGUE LIFE DISCRETE BASE PERIOD 5.2481E8



The abort would occur in the COMPUTE FATIGUE LIFE command.



The FATIGUE MEMBER DATA command which includes the correct position data

that eliminates the abort, is shown as follows:



     UNITS DEGREES

     FATIGUE MEMBER DATA

      2200010 PIPE EQUAL 45.0 SCF VAR USER -

      START SAD AX 6.0 IPB 0.0 OPB 7.5 CRO AX 7.3 IPB 2.4 OPB 0.0 -

      END SAD AX 5.5 IPB 0.0 OPB 8.0 CRO AX 8.0 IPB 2.5 OPB 0.0
