RADAC integrates Norwegian Subsea MRUs for accurate motion-compensated wave data
Dutch company Radac is committed to delivering the most advanced wave radar systems that focus on the task of providing accurate, localised wave and seastate data. To support the highest levels of accuracy and reliability, Motion Reference Units (MRUs) from Norwegian Subsea are used as standard in its WaveGuide radar systems.
This has helped build an enviable reputation for quality in the offshore industry, with Radac’s systems widely recognised for enabling confident decision-making in diverse and dynamic marine environments.
About the collaboration
- Radac delivers wave radar systems for fixed and floating structures, including ships and floating foundations
- Norwegian Subsea MRUs are integrated to provide accurate motion compensation, enabling reliable wave measurements on floating installations such as ships and offshore platforms
- The MRUs deliver real-time roll, pitch, and heave data to support motion-compensated wave monitoring
- Integration supports Radac's goal of delivering reliable and precise wave data in any offshore conditions
- Both companies design systems that do not require recalibration, reducing complexity, costs and downtime
The challenge: Ensuring wave accuracy from moving structures
Radac specialises in reliable wave and sea state measurement systems using unique Frequency-Modulated Continuous-Wave (FMCW) radar technologies. While installation on fixed platforms is straightforward, floating platforms and ships introduce motion that distorts radar readings, making it more difficult to capture accurate wave data.
Motion must be compensated
To achieve reliable measurements from floating vessels and structures, their motion must be removed from the wave data. As Tuna Sener, Business Development Manager at Radac explains, “Our purpose is to measure accurate wave height, wave period, and tide data from a floating structure. In order to do that we need to eliminate or compensate for the motions caused by the waves, otherwise our measurements will be inaccurate.”
Accuracy and reliability as essential deliverables
Clients rely on Radac for critical decision-making and structural validation. This places as much importance on the quality of the WaveGuide system’s input, as it does the accuracy of the data it outputs. Radac assessed various motion sensors before selecting Norwegian Subsea.
"We have tried similar MRUs and Norwegian Subsea was the clear choice, not only for the quality of data, but also the ease of integration"
The Solution: Real-time motion compensation
Norwegian Subsea MRUs provide continuous real-time measurements of roll, pitch, and heave. These inputs allow Radac’s WaveGuide radar to isolate wave motion from platform movement, enabling precision data capture in changing real sea conditions.
Ease of integration built on collaboration
MRU integration is straightforward, and cooperation between the companies is key.
"The collaboration between Radac and Norwegian Subsea has been very positive and has enabled us to overcome challenges that has helped make our technology as reliable and trustworthy as it is today."
No recalibration required
A key value proposition of Radac’s WaveGuide systems is that they do not require recalibration, which is an approach to product development and positioning shared by Norwegian Subsea. The shared design ethos improves operational simplicity, can reduce lifecycle costs, and delivers more system uptime for end-users.
Focus on practical outcomes
While AI, smart operations and digitalisation continue to be in the spotlight, Radac prefers to focus on designing technology for real-world applications, rather than getting too focused on future possibilities. “We tend to develop things that really matter and can instantly be applied to solve the problems our clients face today,” explains Radac’s technical team.
The Impact: Giving end-users confidence to act
Trusted support for operational decisions
Accurate wave information allows operators to act with confidence. Whether validating structures or managing offshore operations, Radac’s systems provide data that supports informed decision-making.
Wave accuracy preserved in motion
With Norwegian Subsea MRUs, Radac systems maintain wave measurement accuracy when operating in rough seas. Our MRUs deliver dependable data that remains accurate including in extreme offshore sea conditions. “With Norwegian Subsea, we are able to provide precision data even in dynamic conditions.”
Minimised maintenance, maximised uptime
Both Radac and Norwegian Subsea offer systems that are factory-calibrated and do not require recalibration. This avoids downtime, reduces costs and ensures consistent long-term performance with minimal intervention.
Collaboration built on results
Radac’s continued integration of Norwegian Subsea MRUs is underpinned by years of cooperation between the two companies. Their work together ensures that Radac offers a motion-compensated wave radar solution designed for accuracy, simplicity and reliability in any offshore environment, regardless of vessel type, platform, or operating conditions.
