The Chergui gas field, located on and around Kerkennah Island, near Sfax, Tunisia, was discovered as part of the West Kerkennah exploration permit granted in the late 1970’s with preliminary reserves estimates of 50 billion standard cubic feet (SCF) under the anticipated development programme. Petrofac’s share of the investment required to complete the development is expected to be USD 20 million. The construction of a 20 million SCF per day central production facility and a 57km pipeline to shore is already underway, the completion of which will be managed by Petrofac. Commencement of production from the field is expected during 2007. Produced gas is to be delivered to Société Tunisienne d’Electricité et Gaz. Remote Control (UK) will supply actuation packages for the Pneumatic quarter turn application. The RCC pneumatic steel actuators are mounted on carbon steel ball valves ranging from 1in to 8in for actuation in order to complete three different design criteria: shutdown valve, blowdown valve and failsafe arrangement. Remote Control will also integrate in the scope of supply: control system packages including solenoid valves; filter regulators and positioners; explosion proof design EEx d, zone 1, group 2B, class T3; air accumulator tanks for three cycles; tank volumes 11/50ltr; and partial stroking devices. All complete units are tested at Remote Control (UK) automation center/ facilites before shipment to Tunisia.
