Creating mathematical models

All of the system variables act together and is represented in a mathematical model which is the foundation of the control system. The operator commands with joysticks or control panel is translated to immediate actions for example the motor and in turn the crane or winch will act based on the logical connections in the mathematical model representing the system.

When presenting the physical crane or winch in a visual representation the digital twin of the system comes to life. You can easily create a visual representation of the system and mimic the system functionality based on basic simplified algorithms. Many simulators are based on this model, but fail to give the operator the experience of how the system actual respond to the commands given.  

 

 

Digital twins in Seaonics

In Seaonics we create the digital twin based on the mathematical models of the components and forces acting upon the actual operation, connect them to the actual real-life control system and visualize the system. The result is a digital twin with identical properties to the real life system.

 

In Seaonics we create digital twins based on the actual real-life control system for two purposes:

1. It gives an increased quality assurance of the project delivery and ensures that the system delivered and performs according to specification
2. It gives the operator a true digital twin of their system and gives the operator valuable experience with how the system works and they can train on various situations

 

 

Digital twin for Odfjell Drilling

One example is the digital twin developed for Odfjell Drilling in the delivery of 90t XT-winch for Deepsea Nordkapp. From March 2019 we were doing operational testing of the seabed operation with the digital twin until first and successful XT-operation May 29^th on Deepsea Nordkapp. See the video of the system here https://youtu.be/35aiXAVMt0U created by cooperation partner Morild Interaktiv.
