Why is MRU important for helicopter deck monitoring?

Motion Reference Units (MRUs) are critically important for Helideck Monitoring Systems (HMS) because they provide precise, real-time measurements of the vessel's or platform's motion. Safe helicopter landings and takeoffs depend heavily on understanding the dynamic movement of the helideck, particularly its roll, pitch, and heave.

An MRU accurately measures these key parameters, delivering essential data to the HMS. This information allows the system, pilots, and deck crew to assess whether the helideck's motion is within the established safe operational limits. Without accurate motion data, attempting landings or takeoffs, especially in challenging sea conditions, poses significant safety risks.

Norwegian Subsea MRUs, such as the MRU Marine (IP68 rated for deck mounting) or the MRU Ex (for hazardous areas), deliver the high accuracy, reliability, and robustness required for this safety-critical application. Our sensors utilize advanced algorithms and state-of-the-art MEMS technology, validated in real sea conditions, ensuring trustworthy data for Helideck Monitoring Systems, thereby enhancing operational safety. Our MRUs meet the requirements of Cap 437 (CAP 437: Standards for offshore helicopter landing areas).
