Virtual twins: the future for ship class, lifecycle management

Mr Bryhni explained how digital twins are used in maritime and offshore applications, enabling greater simulation of operations, better maintenance decisions, improved vessel efficiency, better crew training and to implement remote and autonomous technologies.

“Digital twins support operational decisions, such as when to maintain engines or replace filters, and using vessels most optimally,” said Mr Bryhni.

Owners can use digital twins to decide when to clean hulls, overhaul engines and replace engineroom components. They can be used by naval architects to optimise hulls, and test structural integrity and stability. Digital twins can be used for crew training, helping seafarers to operate vessels more effectively, understand advanced systems and test out scenarios of complex operations in a simulator before implementing them.

Another use case for digital twins is in remote and autonomous vessel operations. Digital twins of unmanned vessels can be used in remote operating centres to support their operation.

“Digital twins give people the best understanding of how vessels behave, replicating experiences on vessels in operation centres,” said Mr Bryhni.

When digital twins are built, they require data from live operations, input from crew and sensors to remain updated.

“A practical challenge is getting high-quality data for use cases and analysis”

“We need standardised data models of vessels in fleets. We run a high number of simulations with a digital twin to gain confidence in the model.”

For different use cases, smaller, purpose-built models could be required, such as to analyse ship propulsion or to train crew on daily operations and prototype offshore activities such as heavy-lift operations.

This will focus on enabling remote control of semi-autonomous vessels where a digital models of vessels and ship systems is needed.

“People will have to be involved,” said Mr Bryhni. “There will be humans in the loop and people on board, so we will need effective human-machine interfaces to help operators interact with autonomous vessels.”

For these operations, vessels will need strong satellite communications through very small aperture terminals and low Earth orbit constellations feeding real-time information into these digital twins.

“We see research is ongoing and developments are evolving in tying these things together for the lifecycle of vessels,” said Mr Bryhni. “There will be a lot of research happening in this area over the next few years.”
