Motion Reference Unit for DP Systems

As a standard sensor requirement in a Dynamic Positioning system, DP, motion sensors (MRU’s) are used to provide data to aid the vessels response to such forces as waves, currents and weather factors.

Whether for a DP1, DP2 or DP3 system SMC has a specific MRU for price and performance to meet the most demanding system and data requirement within the operating envelope under the specified maximum environmental conditions.

Additionally, with a multiple data outputs an SMC-108 can be used in conjunction with a USBL or part of a Helideck Monitoring System linked to the DP system.

Key points

• Roll & Pitch Data
• Heave Data
• DP1, DP2, DP3
• USBL Support
• Ultimate Reliability
• Rugged Construction

Motion Sensor for DP Systems Motion Sensor for DP Systems

Typical DP2 system with USBL Motion Reference Data Requirement would consist of two SMC-007/SMC-107 Roll & Pitch units and an SMC-108 Roll, Pitch & Heave unit.

SMC has a selection of Accessories to ensure ease of install and protection for the MRU units. All units are supplied with a Junction Box, 10m cable and Power Supply Unit as standard.
