Your EMS and HMS Systems Are Running Well.
Let’s Keep It That Way.
Most operators do the right things. Sensors are cleaned, readings are checked, and any obvious anomalies are flagged and resolved. The system keeps running, the data keeps flowing, and there is always something more urgent to deal with than scheduling the next service visit.
That, quietly, is where long-term performance erodes.
Meteorological and oceanographic monitoring systems — HMS and EMS installations in particular — operate in some of the most demanding environments their components will ever encounter: UV exposure, salt air, vibration, moisture ingress, and seasonal extremes that accumulate over months and years. Daily care keeps things operational. Annual service is what keeps them accurate, calibrated, and fit for purpose over the full lifecycle of the installation.
What annual service covers
WISE Group’s general recommendation is a full service review every 12 months. For Helideck Monitoring System (HMS) installations, this is reinforced by regulatory requirements that specify a maximum permitted interval between system verifications — meaning annual service is not just best practice, but a compliance obligation for many operators.
A structured annual service covers a review of system performance against the original specification, sensor status and calibration, firmware currency, communications integrity, and the documentation needed to demonstrate compliance. Depending on system configuration and location, this can be carried out on-site or remotely, and results in a clear record of system status for your own records and any third-party audits.
Resources in the Knowledge Base
Our recently expanded Knowledge Base includes a dedicated Maintenance & Operation section with practical guidance for operators and technicians. Relevant articles include:
- Annual and remote service for HMS and EMS systems
- Routine sensor inspection and care
- Cleaning and environmental effects on sensors
- System verification for regulatory and third-party requirements
- Maintenance, reliability, and warranty considerations
Whether you are preparing for an upcoming service visit, carrying out in-house checks between visits, or verifying compliance ahead of a third-party inspection, the articles are there to support you.
Book your annual service
If your annual service is due — or if you are unsure when it last took place — the best next step is to raise a ticket and let our team take it from there. We will confirm the scope, agree logistics, and get it scheduled.
