Full compliance with IMO MSC.36(63), MSC.96(72), A.694(17) and A.824(19), required for the vessels of 50,000 GT and greater. Delivers high precision measurement required for berthing and docking maneuvers. 3-beam transmission reduces the effects of vessel's pitch and roll in order to output precision measurements. Ground-tracking speed measurement range of up to 200 m. Workload for installation has been greatly reduced thanks to its compact transducer unit. 8.4-inch color LCD display gives high-legibility, real-time information in both graphics and alphanumerics. Remote controller and dimmer controller available. (optional supply) Waterproof box for the display for wing installation. (optional supply) Additional remote display can be selected from color LCD (DS-600/RD-50) and red LED display. (RD-20) Water-tight connector available for the transducer. (selectable upon purchase order)

When a vessel moves through the water, acoustic noise is created and is known as a boundary layer. This noise layer can cause errors with acoustic devices. By measuring speed through water (STW) farther away from the keel, the DS-85 penetrates through this noise and boundary layer resulting in a more stable and accurate speed measurement compared to an electromagnetic speed log. With the new transducer and newly designed process algorithm, the impact of foam is reduced, enabling highly accurate and stable ship speed information. The new compact and lightweight ball-type gate valve is 30% lighter than the traditional valve. When replacing the previous model (DS-80), the same tank or valve can be used, reducing the cost of a retro?t.

DS99 is a single axis Doppler Speed Log, displaying ship’s speed relative to water in one axis(STW, Fore/ Aft) and distance (Trip/ Total) in 7 inch TFT LCD, using Doppler principle. Applying new technology of high integration and stability, DS99 provides you the optimum choice for large ship under 50000 GT. Its rugged and modern design offers excellent user feelings.

Highly accurate and stable measurement tools use high-frequency ultrasonic waves to ensure stable speed data. The JLN-205 incorporates a small transducer that can be mounted on the bow where the effects of foam are least. The ultrasonic beam is transmitted in the fore and aft direction. At the same time, the ship's motions, such as rolling and heaving, are detected and eliminated by simply measuring the difference in the Doppler shift received signal, ensuring accurate and stable speed data even in the most severe conditions. The transducer unit is compact and lightweight and made of molded rubber. It is designed to minimize the effects of ventilation and achieve stable and accurate operation. The JLN-205 Doppler log has a high-visibility 4-inch LCD display. The main data is displayed in large characters for easy reading. Many display modes such as general reader, instruction annotation and graphic reader can be selected from the menu. The Doppler log has a very reliable interface connection area. You can easily connect a range of additional devices to optimize the configuration. These also include a second display, a small remote display and analog indicators. The JLN-205 can also output measurement information to radar and ECDIS. By connecting a GPS receiver, the JLN-205 Doppler log can display comprehensive speed information received from satellites, ensuring highly reliable and accurate positioning.

The JLN-550 Doppler sonar locator is designed to provide you with high stability and stable speed information in dual-frequency mode. The lower ultrasonic frequency ensures the ground speed (up to the maximum depth), and the higher ultrasonic frequency calculates the relative speed of the boat to the water flow with minimal ventilation effects, achieving stable and accurate operation. The ultrasonic beam is transmitted in the fore and aft direction. At the same time, the hull motion, such as left and right rolling and heaving, is detected and eliminated by simply measuring the difference in the Doppler shift received signal, ensuring accurate and stable speed data even in the most severe conditions. The sensor supports dual-frequency transmission, but the volume is smaller than traditional models, and can be installed in the position of the bow that is least affected by foam, achieving stable and accurate operation. By connecting a GPS receiver, the JLN-550 Doppler sonar locator can display comprehensive speed information received from satellites, ensuring highly reliable and accurate positioning. (Optional) Online maintenance is a unique feature that allows you to remotely monitor and analyze the Doppler sonar locator, so that you can take immediate action and provide service for any errors that may occur during navigation. The Doppler sonar locator comes with a very reliable interface connection area. You can easily connect a series of additional devices to optimize the configuration.

The EML900 is a High-performance electromagnetic log using a next-generation master indicator. The electromagnetic log measures the speed and indicates the traveled distance. It does this by measuring the speed through water from the flow of water at the bottom of the ship and calculates the total distance of navigation. There are two types of sensors, a single-axis measuring fore-to-aft and a dual-axis that measures fore-to-aft and the starboard-to-port.

A preamplifier is built into the sensor for stable and long-distance transmission (max.300m long) of the current signal. The EML500 can receive a backup signal(NMEA-0183) from external speed sensors such as a GPS receiver. A dual-axis sensor (optional) measures a ship’s transverse speed as well as its longitudinal speed. HD1 Single Axis diameter 35F double bottom type; HS1 Single Axis 35F diameter single bottom type; HV1/HV2 Single/Dual Axis 70F diameter single bottom type; FA1/FA2 Single/Dual Axis 48F diameter single bottom type.
