SAWOS ensures enhanced operational efficiency, regulatory compliance and safety for offshore installations.

Unrivalled Partnership With Vaisala

We’re proud to serve as the global offshore service partner for Vaisala, a leader in advanced weather-measurement technology. Through this partnership, we enhance our helideck and environmental monitoring services by integrating Vaisala’s industry-leading sensors, delivering precise meteorological data to support safe offshore helicopter operations.

Our technicians have completed specialist training at Vaisala’s Helsinki facility, ensuring they are fully qualified to install, inspect, and recalibrate these critical systems. With a global footprint spanning more than 30 countries, this collaboration strengthens our ability to provide reliable HMS solutions that elevate safety and operational efficiency across offshore environments.

HMS Verification & Calibration

Our Helideck Monitoring System (HMS) provides real-time data on environmental and operational conditions to ensure safe helicopter landings and takeoffs offshore.

Verification and Calibration of the HMS are critical to maintaining the accuracy, reliability, and compliance of this safety-critical system.

Regular verification and calibration are essential to maintain accuracy, reliability and regulatory compliance. Calibration keeps all sensors operating within specified tolerances, preventing errors that could impact flight safety. Verification confirms performance aligns with regulatory standards such as CAP 437 and relevant IMO or CAA requirements. SES Energy’s multi-skilled engineers conduct regular audits, either focused on specific tasks or integrated into multi-scope offshore projects, ensuring your HMS remains safe, compliant and reliable.

BE SAFE, BE COMPLIANT, BE EFFICIENT.
