Message explanations
A-78 385585/C
Corrective
actions:
If control seems to be degraded the thruster should be switched off. Check the
input/output interface. Compare measurements on the DP Operator Station
display with indicators on the bridge console. Replace input interface if there is
considerable deviation. If not, replace appropriate output interface.
Thruster/rudder [#] not ready
Description: This thruster, propeller or rudder is not ready (even though it may recently have
been ready).
The reason for this fault may be that the ready state from thruster, propeller or
rudder system is not active. It can also be an error in thruster, propeller or rudder
electronics, digital input interface, or cabling.
Possible
consequences:
Full station-keeping is not guaranteed. Position/heading alarm may come.
Corrective
actions:
(Re)start thruster, propeller or rudder if possible and wanted. If the remaining
thrust is sufficient the DP is fully operational. Check ready state from thruster,
propeller or rudder system.
Thruster/rudder [#] prediction error
Description: This message is reported if the Azimuth/Force/Pitch/Power/RPM setpoint and
feedback of this thruster do not agree.
The method of detection is comparison between expected and measured feedback.
The reason for the fault may be failure in output interface, thruster control
equipment or input interface.
Additional
information:
•
Azimuth, Force, Pitch, Power or RPM
•
Measured feedback
•
Expected (estimated) feedback
Possible
consequences:
If the feedback loop is faulty the performance will be nearly unaffected. If the
control loop is faulty unexpected movements may be the result. The system may
use estimated feedback instead of measured feedback depending on configuration.
Corrective
actions:
If control seems to be degraded the thruster should be switched off.
Check the input/output interface. Compare measurements on display with
indicators on bridge console. Replace input interface if there is considerable
deviation. If not, replace appropriate output interface.
Thruster/rudder [#] ready
Description: This message is reported if the thruster has become ready for use on DP/TC
(Thruster Control). This means that the thruster can now be controlled by DP/TC.
The reason for this is that the thruster was started from the TC Operator Station,
or the command for the thruster was transferred to DP/TC.
Thruster/rudder [#] RPM feedb failure
Description: This message is reported if there is a feedback failure for this thruster.
