Fertiliser automation system project won in Oman

Invensys Singapore and Invensys Middle East have won a US$3.8 million contract to supply a mesh network-based Foxboro process automation system for use on a major fertiliser project in Oman

The joint efforts of Invensys Singapore and Invensys Middle East have won a US$3.8 million contract to supply a major mesh network-based Foxboro process automation system for use on a major, world class fertiliser project in Oman, promoted by the Suhail Bahwan Group.

Currently under construction at Sohar, the US$638 million Sohar Fertiliser Project of Sohar International Urea and Chemical Industries SAOC (SIUCI) includes a 2000 mtpd (metric tone per day) ammonia plant, 3500 mtpd urea synthesis and granulation plant along with related utilities and offsite facilities.

It is one of the world's largest private sector greenfield fertiliser projects and is being built under an EPC contract by Mitsubishi Heavy Industries (MHI) of Japan.

Under the terms of its contract, Invensys Singapore is to supply a Foxboro I/A Series Version 8 process control system.

This uses advanced commercial communications technologies in robust industrial configurations that will give Sohar Fertiliser a high-availability, self-healing mesh process control network backbone capable of connecting thousands of stations at very high speeds.

The I/A Series process control system will be integrated with Triconex Tricon emergency shutdown (ESD).

The Tricon is a state-of -the-art fault tolerant controller based on a Triple-Modular Redundant (TMR) architecture.

TMR employs three isolated, parallel control systems and extensive diagnostics integrated into one system.

It uses two-out-of-three voting to provide high integrity, error-free, uninterrupted process operation with no single point of failure.

Invensys won this major contract as a result of its excellent reputation in Oman for after sales service, together with its close cooperation within Invensys Singapore, Invensys Middle East and Invensys Japan during the tender evaluation phase of the project.

This win puts Invensys in a very strong position to win other upcoming major contracts in Oman.
