Certified helideck monitoring system for offshore assets,
built for compliance, engineered for reliability, supported worldwide.
Protecting operations. Proving compliance.
Every helicopter movement on your platform depends on real-time, accurate environmental data. A certified Helideck Monitoring System doesn’t just satisfy regulators — it gives your operations team and incoming pilots the information they need to make safe, confident decisions when conditions are marginal.
WISE Group has been designing, supplying, and supporting HMS solutions for over 25 years. Our systems operate on fixed platforms, floating rigs, FPSOs (Floating Production, Storage and Offloading units), and vessels across the UK Continental Shelf, the Norwegian Continental Shelf, Brazilian waters, and beyond — trusted by operators in oil and gas, renewables, and marine sectors worldwide.
Built to comply. Designed to perform.
A compliant Helideck Monitoring System (HMS) must continuously measure and display the environmental parameters that govern whether helicopter operations can safely proceed. The WISE Group helideck monitoring systems are built to satisfy the full range of applicable standards — CAP 437 Edition 9, BSL D 5-1, NORMAM-223, and HCA Standard Rev 9c — for both fixed and moving helidecks.
Standard sensor suite:
- Wind speed and direction (real-time and averaged)
- Air temperature and relative humidity
- Barometric pressure (QNH — sea-level reference; QFE — helideck-level reference)
- Helideck motion — 6 degrees of freedom (for floating rigs, FPSOs, and vessels)
- Visibility and present weather
- Cloud height and cloud amount
DADAS — the proven data acquisition software at the core of every WISE Group HMS — captures, processes, and displays all of this data.
DADAS: Operational clarity under pressure
DADAS (Data Acquisition and Display Software) is designed for one purpose: giving your team the right data, at the right moment, in a format that is immediately actionable. Its interface is straightforward by design — because offshore, complexity costs time.
What DADAS delivers:
- Real-time display of all helideck parameters in clear, unambiguous formats
- Automatic or manual helideck report generation, delivered electronically to helicopter operators and onshore users
- Long-term data logging for post-incident analysis, investigations, and performance audits
- LAN and internet connectivity for remote access and data distribution
- Optional software modules: METAR, SYNOP, HeliMet, DF 22, and further reporting applications
- Scalable from a standalone HMS to a full Environmental Monitoring System (EMS), including MetOcean, Anchor Tension, and Excursion monitoring
DADAS has accumulated a track record spanning over 25 years of deployments across diverse offshore environments — from the North Sea in winter to equatorial waters. It is built for the conditions you actually operate in.
A Helideck Monitoring System Configured for your specific installation
We configure every Helideck Monitoring System (HMS) to your installation’s specific requirements and build it to expand as those requirements evolve. WISE Group does not fit off-the-shelf systems to your operation; we engineer solutions around it.
Fixed and floating helidecks
Full 6-DOF motion sensing for vessels, semi-submersibles, and FPSOs. Fixed platform configurations available without motion instrumentation where not required.
Unmanned installations
An optional ATIS (Automatic Terminal Information Service) module provides real-time audible weather information and remote helideck lighting control for pilots approaching unmanned offshore installations.
System integration
Full integration between the HMS and any other marine, structural, or monitoring systems onboard — eliminating duplication, reducing cost, and simplifying data management across your installation.
Modular expansion
The system’s modular architecture means you can start with a certified core HMS and expand to a complete EMS, adding sensors, users, and capabilities without replacing existing infrastructure.
Deployment flexibility
Rack-mounted, free-standing, or virtual server installation. Trend and history displays are configurable to individual operator requirements.
CAP 437 repeater lights — in partnership with Orga
For moving helidecks required to comply with CAP 437 Ed.9 Chapter 6.4, WISE Group integrates Orga’s L430 HMS Repeater Light system directly with DADAS — giving pilots a live visual readout of helideck operational status at each corner of the deck. Orga is a world-leading supplier of CAP 437 helideck lighting, with its HMS Repeater Light system fully tested across all major HMS suppliers.
Secure cloud data sharing — Orbalux
Share live and historical HMS data securely with helicopter operators, partners, or regulatory authorities through WISE Group’s Orbalux platform. Orbalux connects to DADAS via an outbound-only encrypted link, publishing data to a cloud portal without exposing your operational network.
Remote and onshore access
Live HMS data is accessible to onshore meteorologists, helicopter operators, and operations teams via secure remote connection — reducing reliance on platform personnel to relay conditions manually.
Data retention and audit trail
All helideck parameters are continuously logged and time-stamped, providing a complete audit trail for post-incident investigations, regulatory reviews, and performance analysis.
Redundancy and failover
WISE Group HMS configurations can include redundant sensors and failover display capability, ensuring helideck situational awareness is maintained even in the event of a component failure.
Hazardous area equipment
Sensor and display equipment is available in ATEX-certified configurations for installation in hazardous areas, meeting the safety requirements of offshore oil and gas environments.
Regulatory standards and frameworks
| Standard | Issuing Authority | Applicability |
|---|---|---|
| CAP 437 Edition 9 | UK Civil Aviation Authority | De facto global standard for fixed and floating helidecks |
| BSL D 5-1 / BSL G7-1 | CAA Norway | Norwegian Continental Shelf |
| NORMAM-223 | Brazilian Maritime Authority | Brazilian waters (formerly NORMAM-27) |
| HCA Standard Rev 9c | Helideck Certification Agency | Global |
| ICAO Annex 14 / WMO | International | METAR and SYNOP compliance |
| Canadian regulations | Transport Canada | Canadian operations |
Current systems also support AUTOMETAR/METAR submission to the Norwegian AMHS (ATS Message Handling System) through Avinor’s X.400 API.
Complete helideck oversight with the HAV
Environmental data tells you the conditions. The Helideck Audio & Video Recording System (HAV) records what happened.
Working alongside the HMS, the HAV captures high-resolution video footage of all helicopter operations and logs two-way radio communications between the helideck team and flight crew. Audio and video recording is mandated for Norwegian offshore operations under BSL D 5-1 (§§40–41), and NORMAM-223 includes equivalent requirements for video, audio, and data recording associated with helideck operations in Brazil. Recordings are securely stored and encrypted, and retained for investigations by the relevant authorities where required.
Together, HMS and HAV provide complete operational oversight: real-time data for safe decision-making, and a verified record for compliance, investigations, and regulatory review.
