The RGIs Upgrade and Topside Modification (Debottlenecking) project executed by ISKER for NCOC is a true testament to their exceptional expertise and unwavering commitment to delivering exceptional results for their clients. This challenging offshore project in the Caspian Sea aimed to increase the raw gas injection capacity at EPC-2 and EPC-3, thus boosting the production of the already impressive Kashagan field.
The project was executed during the NCOC Turnaround window of 2022, which presented a significant challenge. But with the help of critical techniques such as SIMOPS, integration with TA & Turbine works, and 3D Laser Surveys, the experienced ISKER team rose to the occasion, executing the project with precision and efficiency.
One of the biggest hurdles of the project was the presence of high H2S and flammable gas inventory under high pressure. However, ISKER's state-of-the-art equipment and techniques, including the use of Inconel 625 & Inconel 825 Piping and two 500 ton capacity mobile cranes, ensured a safe and successful execution of the project.
ISKER's commitment to HSSE standards was evident throughout the project, from providing a safe haven for personnel during general and toxic alarms, to ensuring the use of 100% PAUT with 100% local manpower. The team worked tirelessly, even in night shifts and hot bedding conditions, to complete the project 30 days in advance, out of the 77-day execution period during the turnaround.
ISKER's successful execution of the Kashagan Bundle 1 project is a testament to their capabilities as a reliable partner in the oil and gas industry. Their dedication to delivering high-quality results, combined with their expertise and commitment to HSSE standards, makes them a truly remarkable company. We are proud to highlight their incredible achievements and contributions to the industry.
