iSSMC: Ship Stabilization and Motion Control
Ship Stabilization and Motion Control System (iSSMC)
The iSSMC is a highly integrated Inertial Ship Stabilisation and Motion Control System which uses an integrated inertial measuring unit and an advanced control processor to control the fins and rudders of the ship to improve the comfort of the passengers or to stabilize a working platform on a ship.
- Ship motion stabilisation system
- controls 2 fins or up to 4 fins and 2 rudders / waterjets
- applicable to all usual fin systems
- provides also control data for a stabilized platform (antenna, satellite communication, working platform, helicopter landing deck, heave compensated platform to access wind turbines ...) as an option
The core of the system is an inertial measuring unit which continuously determines roll, pitch and change of heading (and as an option surge, sway and heave) of the ship with appropriate data rate. These data are fused together with the data of an integrated GPS receiver to control the fins and rudders or azimuth thrusters.
The iSSMC provides all interfaces to control the ships actuators (hydraulic or electric torque generators), to read back the actual fin and rudder position, to provide the system status on the CDU (control and Display Unit) located on the bridge and to feed information via CAN to the ship’s PLC and data distribution system. As an option a WAN based data transmission channel can be made available to provide also remote diagnostics and service capability worldwide.
Standard iSSMC can be upgraded to control up to four fins (stern, bow / starboard, port) and two rudders. Customer specific system configurations can be provided on request.
