PRE OWNED SIMRAD AP-9 SIMRAD AP-9 MARINE AUTOPILOT

The Simrad Robertson AP-9 (and the popular AP9 MK3) is one of the most flexible and respected autopilot systems ever designed for professional maritime use. In the Bhavnagar market, it is highly valued for its ability to be retrofitted into almost any existing bridge system, regardless of the brand of steering gear or compass.

SIMRAD ROBERTSON AP-9 MK3 AUTOPILOT

PRODUCT OVERVIEW

The Simrad AP-9 MK3 is an IMO-approved adaptive autopilot system known for its extreme versatility. It is designed to interface with "virtually any type of steering gear," including hydraulic systems, dual solenoid systems, and even thrusters. This makes it a primary choice for refurbished vessel projects where cross-brand compatibility is essential.

Equipped with sophisticated software that "learns" the vessel's rudder response, the AP-9 minimizes overshoot and unnecessary rudder activity. This efficiency not only reduces wear on the mechanical steering components but also provides measurable fuel savings. The control unit features a clear, backlit LCD for heading data and a dedicated bargraph for rudder demand, ensuring the bridge team has total situational awareness.

KEY FEATURES & APPLICATIONS

-- Adaptive Steering Algorithm: Automatically compensates for vessel wear, play in the steering gear, and varying load conditions to ensure precise course-keeping.

-- Dual Compass Support: Can simultaneously monitor two heading sources (e.g., a Gyro and a Magnetic compass) with automatic switching if the primary source fails.

-- Integrated Thruster Control: The AP-9 can be configured to control both the main rudder and a bow/stern thruster simultaneously for enhanced maneuvering at low speeds.

-- Pre-Programmable Parameters: Features two complete sets of steering parameters that can be switched instantly to suit different sea states or vessel speeds.

-- Extensive Interface Options: Compatible with various distribution units (D9X series) to handle different steering voltages and analog signal requirements.

-- Watch Alarm Integration: Includes a commercial watch timer adjustable from 1 to 120 minutes, serving as a critical safety reminder for the bridge crew.

TYPICAL CONDITION (USED/REFURBISHED)

Our refurbished AP-9 MK3 units from the Alang/Bhavnagar yards are among our most requested items. We conduct full bench tests on the D9X Distribution units to ensure the relay contacts and analog output boards are functioning perfectly. The control unit (20169207) is checked for display clarity and backlight consistency. We also verify the NMEA ports for correct data parsing from GPS and Gyro sources to ensure a "plug-and-play" experience for our clients.
