SEPLAT Western Assets Surface facilities in OMLs 4, 38 and 41 have undergone several modifications due to operational requirements, facility upgrades, and maintenance activities. As a result, there is a discrepancy between the documents available for the facility and what is on site. Since a large amount of information is required to safely operate and maintain COMPANY’s existing and new facilities, an update of information is required.
