Exploration of the Nawara region resulted in the discovery of a large quantity of natural gas. A partnership between OMV and ETAP – the Tunisian National Oil Company - was created to extract the gas which would meet the energy needs of the country.
Located in the desert in a very remote area of the Nawara region, the project comprises three main components; a Central Process Facility with related eight Flowlines, a 380-km export pipeline and a final Gas Treatment Plant built in Gabes. Together the new facilities will be able to treat 2.7 million cubic meters per day.
This project is considered the biggest economic driver in Tunisia and will provide growth accelerating the general commercial development activity in the country.
OMV awarded three engineering companies with EPC contracts for the design of the new gas processing facility in the Nawara concession; the Max Streicher – Bouchammoui Industries joint venture for the CPF Process Facility and Flowlines, Enereco for the pipeline and ABB for the Gas Treatment Plant in Gabes.
Health, safety, security and environment were declared the most important features of this project, to be guaranteed for the entire life of the facilities and RINA, thanks to its highly skilled consulting engineering team, was awarded the development of all HSE and Operation & Maintenance activities by all the engineering contractors.
More specifically, a wide range of hazard identification activities were carried out in order to ensure that all safety issues were thoroughly addressed. These activities provided, through the Quantitative Risk Assessment Study and other Safety Studies, the correct input for the safe design of the facilities.
Occupational Health Risk Analysis was developed for setting up the Occupational Health Management System whilst Failure Mode, Effects and Criticality Analysis and Reliability, Availability and Maintainability Analysis provided the input for the Maintenance and Operating activities. This data was used to define a suitable Asset Integrity Management Plan and maximise plant production performance.
The Environmental Impact Assessment, Waste Management Studies, Oil Spill Contingency and Reclamation Plan were all undertaken in order to guarantee the proper protection of the surrounding environment. In addition, specific Security studies were developed for protecting the facilities against external threats.
This project required the development and execution of a full range of complex Safety and O&M activities. RINA also had to ensure operational consistency while supporting three different international contractors. For RINA this represented a very important and significant achievement.
