GARRAF: Implementation of alert and communication solutions to protect installations and the lives of personnel on a high-risk site your title here

River water treatment

Garraf oil field is located in Thi Qar province, approximately 85 km north of Nasiriyah city in Iraq. Waterworks Technologies scope of work included the treatment of water taken from Garraf River to be used for raw wash water and utilities inside Garraf Base Camp. A river water treatment program was set up to produce treated water with a capacity of 1560 m3/day. It is a system that combines filtration and ultrafiltration techniques with all necessary chemical dosages.

ATEX alert and communication systems

Given the environment and the risks involved, it was necessary to set up ATEX alert and communication systems. This helps protect the facilities and the lives of personnel in the event of a malfunction. A2S was consulted and selected to equip the site. The design and implementation of these solutions demonstrate A2S's expertise, its ability to adapt to all types of requests and thus meet all types of needs. Our solutions include the following elements:

• A public address system and general alarm system
• An intercom system
• A radio system
• Fire alarm systems

Unison Intercom System

Atex and Industrial Signaling

The results

As each of the solutions must provide answers to the customer's security needs, we have combined them in the following way:

The sound solution + general alarm

It is a 2 in 1 system combining Public Address PA and general alarm system. We configured it based on A+B system including 1 cabinet with central server, amplifier, monitoring unit and 5 remote cabinet nodes with sub-server and amplifier. The sound is transmitted by 96pcs loudspeaker system (6W for indoor and 25W for outdoor). Besides, we set up 4-zone routine messaging service with alarm message function for worker protection at 5 sites. The operator in the control room can find the person or transmit the alert by voice message. The workers in the field can activate the alarm in case of an accident. With different types of alarm tone, the staff can know what kind of accident has happened and what is the procedure to follow.

The radio solution

It was designed based on a Motorola 1 VHF with battery and antenna and 50 ATEX type walkie-talkies. Thanks to this, it was possible to ensure coverage of the entire GARRAF water treatment plant (utility area, water treatment area, FOB-PWT) in order to protect workers from danger during their daily inspections.

Fire Alarm Solution

It is composed of 3-light status light warning devices, sirens and combined warning devices, and manual alarm trigger, for indoor and outdoor use. This equipment is weatherproof and explosion-proof. In addition, we have installed a complete signaling system to enhance worker safety coupled with a gas detection system. Thanks to the optical and audible warning devices, rapid alarms are issued to warn personnel of danger in noisy areas and to ensure their safety.
