At Nor-Shipping 2017, NYK and DNV GL presented the first results of an ongoing maritime data center pilot project. The data center collects operational data from NYK vessels on DNV GL’s recently launched Veracity industry data platform, for monitoring vessel performance and condition-based maintenance schemes, the company said in its press release.
The collaboration between NYK and DNV GL, supported by engine manufacturer MAN Diesel & Turbo, started in November 2015. Over the past 18 months, four NYK container vessels have been uploading operational data to the platform. An extensive amount of engine data has been collected, for use in vessel performance analysis and a condition-based maintenance and survey scheme. The pilot project has been run in several phases. The first phase has been to build the required components, such as data collection and data management. The second phase focuses on testing data quality, security, access rights and curation of data for use in various applications such as predictive maintenance and vessel performance. And the upcoming third phase will look to pilot new digital business models.
As part of the pilot project, a hierarchical data model is developed, creating a digital twin, which links sensor signals from equipment on board the vessels to support both simple queries and advanced analytics. Machine learning algorithms evaluate the data quality in terms of uniqueness, completeness, and a variety of other parameters. By drilling down into the data, the ship manager can see if all sensors on board the vessel are working properly and easily identify non-performing sensors which may lead to low data quality or missing data during a voyage.
