1. Radar JMA-9923
The JRC JMA Marine Radar series represents a line of high-performance radar equipment crucial for safe ship navigation, designed to comply with international standards like those set by IMO. Applied in maritime environments, the JRC JMA radar systems provide sophisticated features like Automatic Radar Plotting Aid (ARPA) for target acquisition and tracking.
Along with functions for suppressing sea and rain/snow clutter, enhancing target echoes, and managing navigation data. This technology is essential for collision avoidance, positioning, and monitoring surrounding traffic. For repair and maintenance, only maintenance specialists like us -Lemar are permitted to handle the internal components due to the presence of extremely high voltages.
2. Wind Speed/Indicator
A Wind Indicator is a marine instrument designed to measure and display wind speed and direction, providing vital information for safe navigation and vessel operation. The Marinelite Wi 9000s, for example, uses a sensitive wind sensor mounted on the ship’s mast that transmits data to an onboard display.
This system helps crew members monitor both true wind (actual wind over the sea) and relative wind (wind affected by the vessel’s motion). Wind indicators are widely used on ships, offshore platforms, and research vessels to assist with course adjustment, sail trimming, and weather monitoring.
The readings are also often integrated with radar, autopilot, and navigation systems for enhanced operational safety. During repair and maintenance, technicians usually check the anemometer cups or propellers for dirt, salt, or corrosion, verify the direction vane movement, and inspect cable connections for damage.
3. Transas 4000 display
The Transas monitor for ECDIS is a high-performance maritime display designed for use with the Transas Navi-Sailor 4000/4100 Electronic Chart Display and Information System (ECDIS). It provides clear and accurate visualization of navigational charts, radar overlays, and ship data, ensuring safe and efficient voyage planning and monitoring. The Transas ECDIS monitor typically uses marine-grade LCD technology from Jakob Hatteland, offering high brightness, wide viewing angles, and compliance with IMO and IEC standards for maritime equipment.
During maintenance or repair, typical procedures include checking video signal connections, verifying power supply and grounding, inspecting the backlight or display panel for faults, and cleaning internal components.
4. RPM indicator
The M.E RPM Indicator is an essential marine instrument installed on both bridge wings of large cargo vessels. Its main purpose is to repeat and display the main engine’s revolutions per minute (RPM) from the engine control room. This device allows officers on the bridge to accurately monitor the engine speed in real time, especially during maneuvering or docking operations, ensuring safe and efficient vessel control.
Over time, M.E RPM indicators may experience faults such as display errors, unstable readings, or signal transmission failures caused by vibration, salt corrosion, or damaged signal cables. Regular inspection, calibration, and repair are necessary to maintain accuracy and reliability. Our professional marine service team specializes in troubleshooting and repairing RPM indicators from various manufacturers, ensuring precise synchronization between the bridge display and the main engine. With proper maintenance, this equipment continues to play a critical role in navigation safety and propulsion monitoring.
5. Repeater for autopilot
The Autopilot Repeater is a vital navigation instrument installed near the steering wheel or helm console on large cargo vessels. It functions as a repeating unit for the main autopilot system, displaying essential steering information such as the set course, actual rudder angle, and heading data received from the gyro compass. This allows the officer on watch to monitor the vessel’s navigation parameters clearly and maintain accurate steering control at all times.
Due to continuous operation in a harsh marine environment, the Autopilot Repeater can face issues like screen failure, incorrect heading display, or communication loss with the main autopilot unit. Regular inspection, calibration, and repair services are required to ensure the device’s accuracy and stability. Our marine service team provides professional troubleshooting and maintenance for all types of autopilot repeaters, ensuring precise signal synchronization between the steering position and main control system.
