NAVIS - Steering and Thruster Control Systems

The ACP-I offers an absolutely new approach to information display in “lower level” control systems and is the most compact and functional of its type in the industry.

Based on the priority display of alarms and information, the system contains more than 20 possible messages within the boundaries of the screen, thus making the panel multipurpose while keeping its dimensions to a minimum.

The start/stop system combines two principles of operation: electromechanical and logical. This is to improve reliability using additional electromechanical control contacts along with digital CAN bus.

The additional information display contains data about true and required rudder positions, thus avoiding the need for extra electromechanical indicators on the bridge. This, in turn, reduces panel dimensions and makes the system more accessible

The Emergency Steering Control Panel displays the hydraulic pump drive start/stop and provides an alarm signal. The ESC-P panel is specially designed for inexpensive applications and is optional for large vessels providing independent control even when failure of the main controller occurs.

Compact and with highly informative indicators, the unit’s button configuration facilitates easy decision making for operators.

A continuous indication of the status of the hydraulic pump drive means that the panel even updates information in the passive mode.

The FFU lever is equipped with TAKE/GIVE buttons with an active station indicator and an ALARM ACK button. The unit also features a dimmer, operated via CAN-DIM bus to change the highlighting level of the devices supporting this protocol.

For Non-Follow-Up control, an identical NFU lever with the NFU OVERRIDE button can be used.

STCS4000 uses a new type of combined indicator for the required/true rudder position display. The blue-coloured pointer indicates the true rudder position, while yellow-coloured pointer shows the required rudder position. The indicator incorporates a unique system of emergency transfer of pointers to an unseen dial area, in case acceptance limits are exceeded or indicator power failure occurs. This is to prevent the operator misinterpreting the information displayed.

The scale includes a ‘Lead To Current’ indicator that makes it possible to keep the operator informed about the need to match the required rudder position to the true one while switching to other control stations. Before matching the required and true rudder positions, the last set position should be saved.
