Digital Twins for Vessel Life Cycle Service

Alternative title: Digital Twins for Vessel Life Cycle Service

Awarded: NOK 20.0 mill.

Nowaday, modern marine vessels operate increasingly autonomous through strongly interacting subsystems. These systems are dedicated to a specific, primary objective of the vessel or may be part of the general essential ship operations. Between sub-systems, they exchange data and make coordinated operational decisions, ideally without any user interaction. Designing, operating and life-cycle service supporting such vessels are complex, and require an efficient development approach to consider the mutual interaction between subsystems and the inherent multi disciplinarily. Indeed, the work flow in maritime industry does not stop after vessel delivery. Through system updating or due to life cycle maintenance, subsystems can change. The overall behaviour of the entire vessel still needs to be optimal. That requires traceability through a performant data management system that spans the entire product lifecycle. The recent years have seen an increasing interest in developing and employing digital twins for maritime industrial system design, ship intelligence, and operational service. Digitalisation has become a key aspect of making the maritime industries more efficient and fit for future operations. Increased use of advanced tools for designing and evaluating system performance, safety and structural integrity are generating a range of digital models of a vessel and its equipment. In the operational phase, cheaper sensors and increased connectivity together with increasing data storage and computational power, are enablers for new ways of managing a vessel safety and performance. The goal of this research is to develop digital twins of maritime systems and operations, which is an open virtual simulator as next generation of marine industrial infrastructure not only for overall system design, allowing configuration of systems and verification of operational performance, but also providing early warning, life cycle service support, and system behaviour prediction. So far the project has gotten the following achievements. 1. The co-simulation framework is almost ready. The testing version will be soon issued. It is the main result for WP1. 2. Related to WP2, one high level journal on path planning and optimization has been published. Also several new methods for conditional based support for on board system in ship have been developed and published in journals. 3. Related to WP3, a case study has been made already. One publication is on the way. All the milestones and deliveries are fulfilled. The project has been finished according to time schedule.

We made a full scale digital twin of NTNU research vessel Gunnerus. It is a good demo for academia and industry.
