Dynamic positioning system modes and functions

Systems modes

Depending on the application, our dynamic positioning systems can include the following operational modes:

Dynamic positioning system follow target mode
Follow target mode - Enables the vessel to automatically follow a moving target and keeps the vessel within a "position window" relative to the target
  • Joystick: The joystick mode allows the operator to control the vessel manually using a joystick for position and heading control.
  • Joystick high-speed: The joystick high-Speed mode allows the operator to manoeuvre the vessel manually at normal cruising/manoeuvring speeds
  • Auto heading: The auto heading mode automatically maintains the required heading
  • Auto position: The auto position mode automatically maintains the required position and heading
  • Mixed joystick/auto: The mixed joystick/auto mode allows the operator to select automatic control of either one or two of the surge, sway and yaw axes
  • Follow target: The Follow target mode enables the vessel to automatically follow a moving target
  • Anchor assist: The anchor assist mode provides thruster assistance when operating within a mooring pattern
  • Autopilot: The Autopilot mode enables the vessel to steer automatically on a predefined course
  • ROT pilot: The ROT pilot mode allows the operator to manoeuvre the vessel using Rate Of Turn control
  • Auto track: The auto track modes (low-speed, move-up and high-speed) make the vessel follow a specified track described by a set of waypoints. All Auto Track modes are for marine operations only and are not to be used for navigation purposes
  • Track line: The track line mode enables the vessel to follow a constant Course Over Ground (COG). The Track Line mode is for marine operations only and are not to be used for navigation purposes
