Data handling framework for ship performance and navigation monitoring

Summary of research topic and postdoc project

L.P. Perera has developed a machine learning based data handling framework with various data analytics to overcome the respective challenges in ship performance and navigation monitoring. There are various industrial challenges encountered in large-scale data handling situations among vessels and shore based data centers.
The proposed data handling framework consists of pre and post-process sections as onboard and onshore applications, respectively. The pre-process as a part of ship IoT consists of the data analytics with data anomaly detection and parameter reduction/data anomaly compression facilitated by data driven models, i.e. digital models.

The pre-processed data communicate through onboard data transmitters in much smaller improved data sets and that are obtained by shore based data centers through data receivers.
The post-process as a part of onshore data centers consists of the data analytics with parameter expansion/data anomaly recovery, integrity verification & regression and data visualization & decision support facilitated by the same digital models.
These data analytics has special features of self-learning (i.e. data clusters and the structure of each data cluster), self-cleaning (i.e. sensor and DAQ fault removal and compression, data
recovery, data regression & integrity verification), selfcompression & expansion (i.e. parameter reduction and expansion).
Furthermore, that has a multi-purpose structure that can be used for both ship energy efficiency and system reliability applications.
