Offshore Wind

Offshore Wind 4Subsea

Wind energy is a green energy source that is developing rapidly. It is a remarkable source of energy in contrast to the challenges that we see in the oil and gas industry today.

However, we do meet similar obstacles in both sectors. At 4subsea, we have enabled technology transfers that assist operators in reducing the LCOE (Levelized Cost of Energy).

Cost-efficient Technology

4Subsea has developed cost-efficient technology and services for the offshore renewable energy industry. We are a technology-driven company focused on providing services and solutions that can minimise environmental harm, as well as minimise damage to personnel.

Our engineers are continuously improving and updating our technology and solutions. We do this to be leading in the development of efficient and reliable solutions for offshore wind. We want to be part of a positive environmental impact.

Our services include digital twin technology for offshore wind, which enables operators to optimise the production and to reduce costs.

Offshore Wind – Sensor Monitoring

We deliver the SMS Guard™ sensor kit, which is a support system for optimised production from offshore wind turbines. SMS Guard™ is an autonomous sensor kit and digital service for monitoring of floating and bottom-fixed offshore wind substructures.


With the SMS Guard™ Sensor Monitoring, you will get:

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


Areas for cost reduction:

  • Lifetime extension of sub-structures.
  • Lower maintenance costs.
  • Reduction of cable failures and hence reduced cost and risk of production loss.
  • Optimal replacement scheduling; repairing or replacing equipment due to age rather than actual status of equipment.


The offshore wind sensor monitoring system will help operators to realise the potential of reduced costs compared to using traditional digital tools. The system assists operators to make efficient decisions more quickly.

Wind Farms

There is a large market for renewable energy, such as offshore wind energy. Renewable energy is competing with fossil energy sources to obtain sufficiently a low energy production cost. That is why there is a growing need for innovative and efficient low-cost solutions in offshore wind projects, reducing the overall LCOE.

4Subsea can assist with creating economical and valuable solutions for your needs.

Our engineers have developed advanced tools and methods based on extensive accumulated experience, knowledge and sophisticated analysis of substructures used in the offshore wind industry.


Levelized Cost of Energy

Our services and solutions can help with reducing operational efficiency and LCOE. There is great potential to reduce costs by turning to more digitised and economical solutions.

Let us show you the benefits of choosing more accessible  digitised solutions to help avoid loss of production and to have more profitable operations.


The Potential of Wind Power

The potential of wind power is enormous. The energy that we can produce worldwide from using wind power alone could meet all of the world’s demand – without harming the planet and altering the climate.

Wind energy generates no pollutants, and this may be why the wind industry has grown at around 26% each year for the past few years. The market is growing more rapidly than ever, and more companies realize the need for renewable energy.

Avoiding CO2 emissions is becoming more critical to many decision-makers in both smaller and larger businesses.
