Project Year: 2024
EPC Consortium Lead: SUNWISEGLOBLE CORPORATION (SUNWISEGLOBLE)
Location: Erbil Refinery, Kurdistan Region, Iraq
Project Overview
KAR Group’s Erbil Refinery is a mission‑critical petrochemical complex operating in a high‑temperature, dusty, and potentially explosive atmosphere. The client required a plant‑wide PAGA system that would guarantee clear voice and alarm coverage, comply with ATEX/IECEx and EN 54‑16 safety standards, and integrate seamlessly with the Distributed Control System (DCS), telephony, and security subsystems. SUNWISEGLOBLE, acting as EPC Technical Supporter, delivered a full turnkey solution covering system design, equipment supply, factory integration, on‑site installation, commissioning, SAT, and operator training.
Key Technical Challenges
Solution Architecture
IP Core: 24‑bit / 48 kHz Audio‑over‑IP with AES67 media and AES70 control; dual‑NIC controller for rapid switchover.
End‑to‑End Supervision: All amplifiers, speaker lines, and field devices are continuously self‑monitored; faults are reported in real time via a web‑based GUI.
Hazard‑Rated Coverage: Combination of SWLB‑Ex30Y ATEX explosion‑proof horns and L5 30 W constant‑impedance weather‑proof horns ensures 360° intelligibility in process areas.
Interoperability: Multi‑protocol audio I/O (4‑wire/E&M, SIP) permits direct tie‑in with DCS emergency‑shutdown circuits and the existing telephone system.
Implementation Highlights
Factory‑pre‑wired 42 U cabinets accelerated on‑site installation; SAT passed on first attempt in November 2024.
Bilingual (English / Arabic) O&M manuals and hands‑on training enabled refinery staff to assume full ownership within one week.
Web dashboard reduced mean‑time‑to‑repair to <5 minutes by providing granular alarms down to speaker‑loop level.
Principal Equipment Supplied (selection, quantities withheld)
Client Testimonial
