NautoSteer AS is a modular steering-control system from Anschütz. Its configured arrangement can provide follow-up and non-follow-up control with designated control-position transfer and fallback functions. The exact installed modules and wiring must be established before service or replacement is specified.
What identifies the correct NautoSteer service scope?
Use the installed system version, control units and steering arrangement. Similar panel appearances do not establish equivalent functions. Record the failing station and retained local functions before planning a component substitution.
Details that help assess this equipment
- System version and unit part numbers.
- Station and operating mode.
- Available configuration and wiring drawings.
Equipment references and their scope
- Anschütz: NautoSteer AS — An example steering-control architecture; exact fitted variant determines function.
These references explain equipment or system examples. They do not establish the fitted configuration, SEANAV manufacturer authorization or a vessel’s acceptance limits. Use the installed model’s documentation for the actual work.

Information and checks needed
- Identify the installed operator units, feedback devices, amplifiers and system revisions. Compare them with the vessel drawings.
- Review steering-command and rudder-feedback signals, control ownership and the available operating modes.
- Inspect network or supply faults and the relevant diagnostic records before attributing a failure to a single module.
- Plan checks of the fitted fallback arrangement with the bridge and steering-gear personnel, following the maker’s procedure.
Important limits
NautoSteer steering control and an interfaced NautoPilot perform distinct functions. Do not infer the installed redundancy or emergency arrangement from a generic brochure. Review current maker service information, including any applicable feedback-device maintenance notices.
Planning the service
Seanav Marine provides independent technical service support. Share the vessel and equipment details so the desk can confirm capability, the proposed scope, required parts, access and any manufacturer involvement. Review the reported symptoms and available records before deciding whether a field device, interface, supply or controller requires repair.
Agree isolation, operational restrictions and testing with the vessel before attendance. Preserve available configuration records and document any proposed wiring, software or parameter changes. Settings and acceptance criteria must follow the installed equipment documents rather than a generic service checklist.
Documentation and approval
The service record should identify the equipment, work performed, test method, results and unresolved defects. Routine maintenance, manufacturer-authorized work and statutory survey are different scopes. A service report does not issue or renew the ship’s statutory certificates, and no direct OEM agency is implied.
Changes affecting approved navigation, steering or emergency functions may need the appropriate manufacturer, owner, flag or recognized organization review. Confirm that requirement before modifying the installation. Maintenance intervals and test methods depend on the equipment and the vessel’s applicable requirements.
Request support
Send the vessel name and IMO number, equipment identification, port and ETA/ETD, fault description, alarm screenshots and relevant drawings or logs. Include any survey deadline. Attendance, parts and the service scope are subject to confirmation.
