The repair operation of the 16-inch oil transfer pipeline from the Bahregansar platform to the Bahregan onshore facilities was successfully completed with the cooperation of diving teams from the operational areas of Khark and Bahregan, along with support from the relevant production operation units.
Details of the repair operation
Abdul Rahim Davoodi, the head of the Bahregan operational area, announced the details of this project: After receiving a report of a problem in the pipeline, the pressure in the line was reduced to the lowest possible level. To prevent oil from spilling into the sea, the separation of water along with oil was halted, and specialists from the Bahregansar platform took necessary actions to prevent oil leakage by continuously injecting water into the leak area.
Davoodi added: During this period, there was no interruption in the production process. Simultaneously with this operation, a vessel was dispatched by the marine operations unit along with HSE experts to the area, and the spraying of materials to combat oil pollution was carried out in the vicinity of the leak site.
Project challenges and actions taken
The head of the Bahregan operational area pointed out the geographical conditions of the Bahregansar oil field, stating: The high concentration of sediments and near-zero underwater visibility made the diving operations significantly complex and operationally challenging. Due to visibility limitations, part of the operation was conducted by divers through tactile means.
After five days of drilling operations using the dredging system, access to the pipeline for the next stages of repair was made possible. Davoodi stated: Using specialized underwater hydraulic equipment, the exact point for repair was identified, and divers proceeded to install the leak clamp and tighten it.
After the clamp was installed, the pipeline was subjected to standard operational pressure from the platform, and to ensure the proper functioning of the clamp, its status was continuously monitored for 24 hours.
The head of the Bahregan operational area, referring to the confirmation of the clamp's proper performance, said: After ensuring the stability of the repairs and placing the pipeline under the operational pressure approved by the region, this hard and complex project was successfully completed.
Davoodi also appreciated the efforts and cooperation of the executive team of this project, particularly thanking the production management, the Khark operational area, the diving teams, and various units involved in this operation.
