Dynamic positioning system modes and functions

Our dynamic positioning systems can be operated in a variety of different modes.

Systems modes

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

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
