Speed Log · Position & Heading
Tokyo Keiki ES-5100 is a marine speed-log system. It is normally installed on the bridge with underwater sensor equipment in the hull and display or processing units in the navigation console. Its primary purpose is to measure vessel speed for navigation, collision avoidance and other bridge systems. Compared with GNSS-derived speed, a dedicated log measures speed from its own hull-mounted sensor principle and may provide water-referenced or ground-referenced information depending on the installed technology. The supplied record already contains the available concise model or rating information, so those existing figures are not duplicated here and no additional meaning is inferred from the model code. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect accessible transducer connections, cabling, processor and display. Compare indicated speed with independent references while considering current and sensor type. Check data output to radar, ECDIS and other consumers. Exact calibration values and docking inspection criteria require manufacturer documentation.
Carry fuses, interface cables, approved processor or display modules and transducer service components where supported.
