Motion Reference Unit for DP Systems

As a part of the Dynamic Positioning system a motion reference unit is used for aiding and compensation of vessel motions.

The SMC motion reference unit IMU-007 is frequently used in all the DP system variants DP1, DP2 and DP3 for roll and pitch measurements of the vessel.

Depending of the requirements of performance for the mru and the class of DP system, the IMU-00x model and IMU-10x model are selected as appropriate.

Motion Reference Unit for Active Heave Compensation

As a part of the Active Heave Compensation system the motion reference unit provide essential data for the main controller for heave compensation during vessel motions.

The IMU-008 is a cost effective mru for applications such as AHC winch and recovery systems.

SMC is working together with multiple AHC system designers with new build and retrofit modular systems that reduce the investment required in new control systems.

Motion Reference Unit for Hydrographic Survey

In the hydrographic market for single beam, sidescan sonars, sub bottom profiler and fishing multi-beam systems among others where heave compensation is of importance the IMU-008 motion reference unit is cost effective solution.

As an alternative to the IMU-008 the motion reference unit model IMU-108 is frequently used in systems such as shallow water seafloor, harbour and coastline mapping using multibeam sonar systems.

Motion Reference Unit for Helideck Systems

Mega and Super Yachts have an ever increasing sophistication in the systems to meet the high market expectations for accessibility where ever in the world they are located. Helidecks are often a standard requirement governed by the Large Yacht Code, LY3 or the Passenger Yacht Code though a client’s high expectations often the use of industry standard CAP437 compliance is requested.

To fulfill these expectations SMC offer the IMU-008 mru to work with other systems along with the SMC helideck monitoring system and a variety of weather instruments that can provide all the statutory data and customer usability required.
