Digital Twin Technology

Digital Twin Platform


4Subsea provides services, products and support systems that use digital twin technology to enable operators to “know it before it happens”.

Our solutions assist operators with critical decision-support and help fix an issue before it happens by using a digital twin.

Digital twin technology gives you the ability to track and gather data in real-time from a  subsea asset or wind turbine using IoT sensors connected to the cloud services.

Digital Twin in Offshore Wind

Are your company an offshore wind-based company who is looking for a way to reduce costs, and to predict potential outcomes and loss of production?

At 4Subsea, we deliver crucial decision support for optimised production for offshore wind turbines. We deliver an autonomous sensor kit called SMS Guard™, used for monitoring wind substructures that are floating or bottom-fixed.

This solution uses and provides key decision support through a digital twin. This way, wind farm operators can detect anomalies, predict operational issues and fix any issue before it happens.

Benefits Experienced Using SMS Guard™

The SMS Guard™ Sensor Monitoring is a monitoring system used for subsea monitoring. It can help operators predict the potential outcome “before it happens”.


The system provides benefits such as:
  • Decision support as an easy-to-use digital service.
  • A simple to install instrumentation package that enables continuous integrity monitoring of offshore wind turbines.
  • Autonomous, retrofittable sensors, combined with advanced machine learning algorithms.
  • 4Subsea’s domain expertise to help operators realise the significant potential of reduced LCOE (Levelized Cost of Energy).


This monitoring system assists operators in realising the potential of reduced costs compared to using traditional digital tools. The system also helps operators to make efficient decisions more quickly.


It helps your company lower costs in areas such as:
  • Maintenance and operational costs
  • Optimal replacement scheduling; repairing or replacing equipment due to age rather than the actual status of equipment.
  • Reduction of cable failures and hence reduced cost and risk of production loss.
  • Reduced capital expenditures with a lifetime extension of sub-structures beyond design life.


Digital Twin Drilling

A digital twin can be used to avoid aborting drilling operations. Together with Lundin Norway, we have developed a case study where we are showing how digital twin technology works using our SWIM™ solution. Lundin Norway avoided escalated conductor instability by utilising a well specific digital twin.


We combine the following to create effective digital twins:
  • Machine learning
  • Anomaly detection
  • Artificial intelligence
  • Advanced algorithms
  • Prediction analysis
  • Domain expertise
  • Expert engineering
  • Operational experience


By combining these, we see that this provides decision support to both onshore and offshore operations.


The results of the Lundin case at Luno II

In the spring of 2018, Lundin Norway experienced escalating conductor instability while drilling on one of their exploration wells. The instability was caused by soil wash-out, resulting from vessel and wave induced motions on the BOP and by challenging soil conditions. Lundin Norway used an ROV to visually observe the movements of the BOP.

By using the well specific digital twin to update conditions, evaluate the consequence and verify wellhead integrity throughout the remains of the operation after soil stability issues, the operation did not have to be aborted. The drilling campaign continued, with the benefit of significant cost savings.

Benefits of Using Digital Twin Technology

Some experts describe digital twin tech as “powerful masterminds to drive innovation and performance”. A digital twin is a useful tool that can help a company with advanced monitoring and analysis.

The digital twins are predictable, and companies who use this technology will most definitely see an improvement in reduced costs and improved physical assets.

Through this technology, companies can learn how to predict anomalies and damages before they happen. Are you interested in learning how your company can benefit from this? Contact us for more information!



At 4Subsea, we have developed cost-efficient solutions, technology and services for the offshore renewable energy industry and oil and gas.

We are a team of slightly geeky engineers. We are a technology-driven company who are focusing on providing services and solutions that can minimise environmental harm, as well as minimise damage to personnel.

Our dedicated team of engineers are always improving, updating and rethinking our technology and solutions. We do so to be one of the leading companies in the world when it comes to developing reliable, safe and cost-efficient solutions for companies.

We provide decision support systems that help oil & gas and offshore wind operators to “know it before it happens” so that they can avoid costly repairs or production shutdown.



4Subsea was established in 2007, and today, we are a leading provider of engineering systems and subsea technology, solutions and services. Our clients include the major energy operators in the world.

By combining expert engineering competence, operational experience and digitalised decision support, we ensure the integrity of subsea assets from the reservoir to the deck.

We want to be part of a positive environmental impact, and that’s why we always have this in mind when developing new solutions.
