Engine diagnostic system
WiDE uses the EDS to analyse and compare data against predefined references,
identifying any discrepancies between ‘reference’ and ‘actual’ data. The findings
are then consolidated, and any predicted issues or required actions are high
-
lighted to the crew. This allows for improved planning and automation of subse
-
quent supporting processes like troubleshooting, maintenance, spare parts
handling and identification.
Analysis
The EDS analyses the DCM data to obtain a full engine diagnostic by using sev
-
eral methods:
•
The ‘digital twin’, an engine thermodynamic model which is calibrated at
the engine’s shop test and sea trial, receives and simulates real-time engine
parameter inputs. This provides an ongoing performance assessment by
measuring any deviations between the simulated model and the real engine.
•
An algorithm rule set is used to monitor, analyse and diagnose the sub-
system components. It encapsulates WinGD’s expert knowledge by consid
-
ering calculations, documentation and investigations.
•
Data trends are recognised from a combination of DCM monitoring and
historical sample data that is uploaded to the EDS during installation, ena
-
bling progressive performance improvement.
Prediction and
troubleshooting
This ongoing analysis is consolidated to a final output, allowing the EDS to
make predictions. If a potential ‘critical’ fault is diagnosed the crew is notified,
enabling them to decide on immediate action. However, if no action is taken, the
EDS will proceed with the troubleshooting process in the following sequence:
•
At the initial stage all proposed actions largely follow the directions of the
engine’s operation manual.
•
Followed by recommendation procedures defined by the maintenance
manual, the EDS may also connect to the Planned Maintenance System
(PMS), updating the maintenance plan and the spare parts list.
•
If required, the EDS will connect to external help and support, potentially
engaging with human experts through on-line and remote troubleshooting.
•
Once the risk is resolved, the EDS collects all the available feedback and
creates relevant reports archiving it for future references.
Support
As well as the actions mentioned above, when the EDS responds to single-case
instances or potential issues, it also provides ongoing supports other ways:
•
The troubleshooting module keeps track of current issues, collecting and
displaying data.
