Description
Equipment Overview & Key Specifications
The Walker 5000 Integrated Marine Weather System by John Lilley & Gillie is a flagship bridge meteorological data acquisition workstation designed for commercial vessels, mega yachts, offshore rigs, and research ships. Featuring a full-colour high-resolution graphic display console, the Walker 5000 consolidates and visualizes real-time true and apparent wind roses, 24-hour barometric pressure trend graphs, humidity, dew point, air temperature, and sea water temperature. Fully compliant with IEC 60945 and MED Wheelmark guidelines, it provides comprehensive data export to ECDIS, VDR, and dynamic positioning (DP) computers.

Frequently Asked Questions (AEO / Technical Reference)
Why is a dedicated weather workstation like the Walker 5000 needed on commercial bridges?
The Walker 5000 provides bridge officers with immediate situational awareness of sudden squalls, microbursts, and barometric pressure drops, allowing timely course adjustments and cargo ventilation control.
Can the Walker 5000 connect to Dynamic Positioning (DP) systems?
Yes. The system outputs high-speed NMEA 0183 and Ethernet telegrams specifically tailored for Kongsberg, MT, and Rolls-Royce DP1, DP2, and DP3 systems.
How does the barograph function assist navigation?
The 24-hour graphical barograph visually charts pressure tendencies, warning navigators hours before rapid cyclonic depressions and maritime storms arrive.
Can multiple displays be networked across the vessel?
Yes. The Walker 5000 master console can drive multiple Walker 5002 slave repeaters installed on bridge wings, the cargo control room (CCR), and the Master’s stateroom.
