FEED OBJECTIVES

Engineer a feasible repair method that can be executed by available installation contractors in the region

Develop a method based on use of industry proven equipment and procedures

Review the method with potential EPCC contractors to get feedback on their construction risks.

Develop a method which offers no or minimum stoppage of Gas to the consumers

Develop a method which enables restoring the gas flow to the full design pressure as early as possible

Conduct risk work shop and identify risks that should be managed by PMT

Identify long lead items for procurement so that repair work can be executed as early as practically possible
