Riser Monitoring

NORSUB Subsea Motion Sensors provide accurate, real-time measurements of roll, pitch, yaw, surge and sway velocities and positions. State-of-the-art MEMS sensors give robust and accurate measurements. Communication is via Ethernet, RS-232 or RS-485. A range of industry standard and custom protocols are available for easy interfacing. A riser is typically fitted with 3 – 5 subsea motion sensors along its length and data is transferred via a subsea cable to a topside monitoring system. NORSUB subsea sensors have low power consumption and compact size. They are easily fitted to the riser by customizable brackets and clamps.
