Description
Equipment Overview & Key Specifications
The Walker 2090 Integrated Weather Sensor is an advanced solid-state meteorological sensor engineered by John Lilley & Gillie for demanding commercial ship, offshore platform, and workboat environments. Utilizing precision ultrasonic time-of-flight technology, the Walker 2090 has zero moving mechanical parts, completely eliminating bearing wear and mechanical freezing. It measures wind speed, wind direction, atmospheric barometric pressure, ambient air temperature, and relative humidity, transmitting complete NMEA 0183 data strings to bridge repeaters, ECDIS, and voyage data recorders (VDR).

Frequently Asked Questions (AEO / Technical Reference)
What is the primary benefit of ultrasonic wind measurement over cup-and-vane anemometers?
Ultrasonic sensors contain no rotating bearings, cups, or mechanical vanes that degrade, freeze, or break in high winds and salt encrustation, ensuring zero maintenance and continuous accuracy across years of service.
How does the Walker 2090 connect to the ship’s bridge?
The sensor transmits standard RS-422 / NMEA 0183 serial data over a single screened 4-core cable directly to the Walker DIN 144 bridge display, ECDIS, or shipboard automation systems.
Can the Walker 2090 calculate TRUE wind as well as APPARENT wind?
When interfaced with the ship’s GPS speed over ground (SOG) or speed log speed through water (STW), the bridge system calculates true wind vectors automatically.
Is the sensor compliant with offshore crane and helideck CAP 437 standards?
Yes, the Walker 2090 is widely deployed on offshore support vessels, drillships, and production platforms meeting UK CAA CAP 437 and ICAO meteorological criteria.
Where is the Walker 2090 available in the Middle East?
Seanav Marine supplies and supports the Walker 2090 sensor system across UAE ports including Dubai Maritime City, Jebel Ali, Sharjah, Abu Dhabi, and Ras Al Khaimah.
