ore of the worldwide fleet has been fitted with machinery sensors to allow owners to use onboard data to improve
operational efficiency and enhance maintenance procedures. The growing amount of data generated by these networks of sensors means shipowners need to employ more advanced analysis tools to process the data into intelligent information. The adoption of this information analytics is leading the maritime industry into the industrial internet age. Engineering Software Reliability Group (ESRG) estimates that if the global fleet adopted industrial internet technology, it could create up to US$20 billion of opportunities for owners, operators and managers in reduced costs, fuel efficiency, and increased asset uptime and reliability. This is according to the report Bringing the industrial internet to the marine industry and ships into the cloud, written by ESRG’s president Ken Krooner and its general manager Rob Bradenham.

smarter machines and more robust technology, that value-creation potential is projected to grow at 15-20 per cent per year for the next five years. “The benefits to marine stakeholders are significant. Substantial fuel savings, reductions in maintenance and repair costs, and greater assurance of environmental compliance are the largest drivers,” said Mr Krooner and Mr Bradenham in the report.

“Many marine organisations need to bolster their technology and data analysis capabilities in order to take advantage of these opportunities. Some companies are already investing in data collection. But often this means they are overwhelmed with data, so the data can sometimes be ignored. Real- time automated analytics on a vessel and on shore are necessary to transform the raw data into actionable information that can be used to make better operational and maintenance decisions.” To realise these opportunities, shipowners

should employ more comprehensive monitoring and control systems, better broadband communications, and software for analysing huge volumes of data. However, there are significant technical challenges, especially the huge volume of data generated, that will affect the adoption of industrial internet technology. The huge volume of sensor data is one of them. New vessels have more than 1,000 data points, creating 2.5 billion pieces of data over a month. Therefore, a fleet of 100 of these vessels would produce 3 trillion data points per year. If analysed properly, this data could be used to operate and maintain equipment at higher performance levels and lower costs, by adopting condition-based maintenance (CBM) strategies. Analytic software can integrate a variety of data sources in multiple formats and use automated algorithms to turn data into actionable information. The information then needs to be available through multiple channels, including
