⏱️ 5 min read

Explore SEANAV MARINE’s India catalogue for YDK Technologies and legacy Yokogawa navigation equipment, spares and service enquiries. Select the actual equipment or part below, then provide the full model designation and vessel schedule for a confirmed quotation.

Find the right YDK model or spare

Gyrocompass systems, gyrospheres, repeaters, autopilots, electromagnetic speed logs, displays and course recorders perform different jobs. A model family or seller SKU alone does not establish interchangeability.

Repeaters

Product or part What to confirm
YDK Technologies MKR056 Steering Repeater Compass Send the full nameplate code, mounting photographs, master compass model and wiring details so the correct configuration can be reviewed.
YDK Technologies MKR050 Gyro Repeater Compass Confirm the full model suffix, input arrangement, power rating and mounting details from the installed unit and drawings. A matching appearance does not establish electrical compatibility.

Gyro

Product or part What to confirm
YDK Technologies CMZ900 Gyrocompass Identify the complete system as CMZ900B/B2, CMZ900S or CMZ900D, and include the master-unit nameplate, serial number and connected repeaters.
YDK Technologies MKT007 Gyrosphere for CMZ900 Send the existing sphere marking, master-compass model and serial number. Confirm the exact suffix, service kit and installation requirements before ordering.
YDK Technologies KT005 Gyrosphere for CMZ500 / CMZ700 Provide the existing gyrosphere code and suffix, master-unit model and serial number. KT005 and MKT007 must not be treated as interchangeable merely because both are gyrospheres.
YDK Technologies KT005 Gyrosphere for CMZ700 Send photographs of the sphere label and CMZ700 master-unit nameplate, together with the last service report and required port date.

Speed Logs

Product or part What to confirm
YDK Technologies EML500 Electromagnetic Speed Log Identify the master unit, indicator, sensor code and hull fitting. State whether you need a full system, a compatible component or a service assessment.
YDK Technologies EML900 Electromagnetic Speed Log Send the complete system code, sensor and sea-valve details, master-unit and indicator types and installation drawings. A system family name does not define the full supplied package.

Recorders

Product or part What to confirm
YDK Technologies MDR290 Paperless Course Recorder Specify the installed recorder code, input sources, software or storage details where available and whether the requirement is a complete unit, spare or repair assessment.

Displays

Product or part What to confirm
YDK Technologies MHR110A Universal Data Display Provide the complete model suffix, existing display function, source equipment, electrical ratings and mounting dimensions from the unit or drawings.
YDK Technologies MHR112 Assist Monitor Send the full model and suffix, displayed function, nameplate, mounting arrangement and interface drawing. A monitor listing does not imply independent heading or speed measurement.
YDK Technologies MHR120 Universal Data Display Include the full suffix, display function, source system, rating and mounting photographs. Confirm the applicable configuration before comparing it with another MHR-series unit.
YDK Technologies MHR130 Analog Indicator Send a clear photograph of the scale and full nameplate, together with the source system and wiring details. Confirm range, units and mounting before ordering.

Autopilot

Product or part What to confirm
YDK Technologies PT900 II Autopilot Send controller and cabinet nameplates, serial numbers, software details where available and steering interface drawings. The listing name alone does not establish that two PT900 assemblies can replace each other.
YDK Technologies PT900 Marine Autopilot State the full PT900 designation, steering-gear interface, controller details and current system drawings. Specify whether the requirement is a complete system, replacement unit, spare or service visit.

Maintenance, repair and overhaul

Requests can concern fault diagnosis, preventive maintenance, workshop repair, a replacement component or equipment-specific overhaul. Share alarms, previous reports and installation drawings so the responsible personnel can confirm parts, test procedures and service documentation. Required OEM, flag or Class authorization is checked for the actual work; a catalogue entry does not establish blanket authorization.

Legacy Yokogawa identification and support

Older equipment may carry a Yokogawa Denshikiki nameplate. Send the original marking and serial number with your enquiry. For CMZ700 systems, review the YDK service-parts notice and check current parts availability before planning maintenance or an upgrade. Different KT005 and MKT007 listings must be assessed against the fitted gyrocompass.

Country and port enquiry locations

The following links are locations in the existing SEANAV service directory. Share any other country, port, shipyard or offshore location for assessment. Attendance, parts delivery, freight, local partner availability and port access are confirmed for each enquiry.

Questions before ordering or booking service

Can I request service without ordering a new product?

Yes. Send the model, fault history and vessel schedule. The desk will assess repair, maintenance or overhaul scope separately from replacement supply.

Can you supply or attend at my next port?

Send the country, exact port or terminal, ETA/ETD and agent details. Availability, access, freight and a service arrangement must be confirmed before a commitment is made.

Are all parts in the same family interchangeable?

No. Full part codes, suffixes, serial numbers, electrical interfaces and mounting arrangements must be checked against the installed equipment and documentation.

Request a YDK product or service quotation

Email service@seanav.org with vessel name, IMO number, full model or part reference, quantity, fault or work required, nameplate photographs, country, port and ETA/ETD. Ask for the equipment condition, documentation, service scope and applicable transportation charges in the quotation.
