How to design a critical communications network for an offshore platform complex: inter-platform redundancy, ATEX/IECEx Zone 1 certification, Zetron dispatch integration, and migration without stopping production.
Hydrocarbon operations on platforms off Peru's northern coast (Talara and Tumbes basins) combine marine corrosion, tropical Pacific conditions, and strict ATEX/IECEx Zone 1 requirements. The typical design scenario: modernizing communications across a multi-platform complex with production continuity as the primary requirement.
Marine-grade Rajant BreadCrumb nodes with dual-band links between platforms — 5.8 GHz primary for throughput, 900 MHz fallback for fog penetration — with InstaMesh switching in milliseconds. IECEx-certified nodes in classified process modules. A Zetron ACOM console at the hub platform integrates VHF marine radio (GMDSS channel 16), internal UHF, VoIP over the mesh, and prioritized process alarms on a single dispatcher screen.
Phase A: mesh infrastructure installed in safe areas while the legacy system remains active, with parallel commissioning. Phase B: cut-over in a short planned maintenance window, dispatch migrating last with the legacy console as fallback until nominal operation is confirmed. Regulatory documentation (IECEx certificates, HSE functional safety assessment, GMDSS compatibility, availability records) is part of the project scope.
