2.2.4.1 Operation Mode: Consequences Analysis

In Auto Positioning Mode the AlphaDynaPos DP software will continuously verify that the vessel can maintain its position,

even if the worst case failure occurs. The software verifies that the thrusters remaining in operation can generate the

same resultant thruster force and direction as required before the failure.

The consequence analysis will generate an alarm if the occurrence of a worst case failure will lead to a loss of position

due to insufficient thrust for the prevailing environmental conditions.

Note On classified systems Auto Heading mode is not available due to class requirements.

The vessels' heading is kept to the Set Heading and the vessels' speed is controlled by the joystick forward movement.

Only the main thrusters and rudders are used in this mode.

When entering this mode the Set Heading is default set to the actual compass heading.
