The package “Operational Analyst” includes complete or customized analysis catalogs that offer in-depth information about the vessel operation. The fact sheet for the Data Analysis Catalog can be found on the hoppe-marine.com website.

Yes, all system-included sensors and values can be monitored. The detection of failed interfaces and malfunctioning sensors, as well as testing the exceedance of operationally not reachable limit values are part of the scope of performance. Normally, in-depth validation algorithms that assume knowledge about sensor behavior, can only be applied to sensors made by Hoppe Marine.

The data quality is based on the quality of every single signal. One can distinguish between Primary Signals (data essential for reporting and optimization of operation) and Secondary Signals (further ship operation data for monitoring, planned maintenance, etc.) to output aggregated quality. The quality for each signal is calculated in consideration of invalid and implausible data (limit value exceedance, etc., application of algorithms).

Furthermore, with the Data Analysis Catalog a correlation matrix will be created, including the evaluation of different engineering processes and their relationship on board. The correlation has no direct influence on data quality, since in this case an evaluation for the exact determination of the faulty input variable is performed by a technician.

In case a signal is transmitting invalid data of a normally intact sensor, a check regarding implausible behaviour due to unfavorable environmental or operating conditions is done, to figure out whether the sensor is malfunctioning or not. For example, the alleged offset of a flow meter on a ship during standstill can be of various reasons.

In case conspicuous sensors are detected, further agreements with clients are possible to directly offer corresponding spare parts and service jobs.

Daily evaluation of data quality is performed by a team, consisting of marine engineers, naval architects and experienced service technicians. For at least once per working day, the team visualizes and traces data losses, implausibilities and deterioration in quality on the highest aggregated level. Based on sudden events and also on gradual changes, technical clarification and troubleshooting is done. Situations which can be solved internally by analyzing the data with the Hoppe Marine Signal Inspector, Data Analysis Catalog or by remote access, as well as the communication with clients or third party providers in terms of interface troubleshooting, are part of the daily business.
