SES unveiled the Scalable Aviation Weather Observation System (SAWOS) in 2023, establishing a new benchmark in offshore aviation support for the company. This innovative system is specifically designed to enhance operational efficiency, safety, and cost-effectiveness for offshore floating installations and vessels.

Designed to meet the most challenging offshore conditions, discover the key features that position SAWOS as a market leader in offshore operations:

1. Real-time accurate data for enhanced safety

SAWOS provides precise, real-time data on a range of critical factors, including helideck surface conditions, surrounding airspace, and weather conditions. This real-time information supports safer and more efficient helicopter operations, whether it’s for pre-flight planning or during the flight itself. Accurate data on wind, barometric pressure, air temperature, humidity, and visibility ensures that offshore helicopter landings and take-offs are conducted under optimal conditions, significantly reducing the risk of incidents.

2. Comprehensive helideck and environmental monitoring

Unlike traditional helideck monitoring systems, SAWOS goes beyond basic functionality. It integrates both helideck monitoring and environmental monitoring into a single, scalable system. The environmental monitoring component offers a broader scope, including features such as acoustic doppler current profiling, strain gauges, lightning detection, and calibrated forecasting. This integration allows for a holistic view of both the helideck and surrounding environmental conditions, facilitating better decision-making and operational planning.

3. Compliance with industry standards

SAWOS is fully compliant with existing and future industry standards, including the UK CAA CAP437 and Norwegian standards. This ensures that the system meets stringent safety and regulatory requirements, providing peace of mind to operators and stakeholders. By adhering to these standards, SAWOS guarantees that it is not only effective but also aligns with global safety protocols.

4. Fully customisable to client requirements

A defining feature of SAWOS is its exceptional level of customisation. The system is designed to be tailored to meet specific client needs, offering flexibility in its configuration and functionality. Whether a client requires specific environmental sensors or unique data reporting features, SAWOS can be adjusted to suit individual operational requirements, enhancing its value and effectiveness for diverse offshore scenarios.

5. Accessible from any device

The system can be accessed from a variety of devices, including Microsoft Windows PCs, tablets, and mobile devices. This accessibility ensures that operators can monitor and manage their offshore operations from anywhere, whether they’re on-site or remote. The user-friendly interface makes it easy to retrieve and analyse data, ensuring that decision-makers have the information they need at their fingertips.

6. Integration with existing sensors

To streamline the installation process and reduce costs, SAWOS is designed to integrate seamlessly with existing sensors and systems. This feature allows operators to leverage their current equipment while benefiting from SAWOS’s advanced monitoring capabilities. The integration also helps maximise cost-effectiveness and operational efficiency by reducing the need for additional hardware.

7. Worldwide support and remote diagnostics

SAWOS is supported globally by SES’s network of specialist engineers, ensuring that help is always available no matter where the system is deployed. Additionally, the system includes remote diagnostics and software upgrades, which keep it up-to-date with regulatory changes and technological advancements. This ongoing support ensures that SAWOS remains a reliable and cutting-edge solution throughout its operational lifespan.

8. Versatile environmental monitoring capabilities

The environmental monitoring component of SAWOS is designed to interface with a wide range of sensors and monitoring systems. This versatility allows for comprehensive environmental data collection and sharing, enhancing operational insights and efficiency. Features such as stress monitoring, water status, and environmental analytics provide valuable information for various offshore applications, from crane operations to vessel planning.

9. End-to-end helideck and refuelling solutions

In addition to its monitoring capabilities, SAWOS complements SES’s extensive range of helideck and refueling services. SES offers a full suite of services including helideck audits, friction testing, maintenance, and refueling systems supply. By integrating SAWOS with these services, SES provides a complete end-to-end solution for offshore aviation operations, helping operators save time and reduce costs.

10. Advanced functionality beyond traditional systems

Finally, SAWOS stands out for its advanced functionality compared to traditional helideck monitoring systems. Its enhanced capabilities, such as real-time environmental data integration and customisable features, set it apart in the market. This advanced functionality not only improves safety and efficiency but also unlocks new possibilities for offshore operations, pushing the boundaries of what’s possible in aviation support.


With real-time data, comprehensive environmental monitoring, and full compliance with global standards, SAWOS enhances both safety and operational efficiency. Its integration with existing systems and global support network makes it a highly versatile and cost-effective solution. By providing end-to-end helideck and refuelling services, SES ensures that SAWOS offers a complete, cutting-edge package that redefines offshore aviation support.
