Through a competitive bidding process, ADNOC Offshore awarded the EPC contract for seven jackets under the Umm Shaif Long-Term Development Program Phase 2 (US LTDP-2) and Lower Zakum Early Production Scheme Phase 2 (LZ EPS-2) to National Petroleum Construction Company (NPCC). The EPC contract scope covers engineering, procurement, fabrication, installation, and commissioning. This project aims to sustain and enhance production efficiency while unlocking long-term potential at both fields.

Through intensive collaboration with CNOOD-Wenchong Heavy Industries Co., Ltd. (CWHI), Ziking secured the jacket fabrication subcontract after passing ADNOC and NPCC's factory qualification audits and being included on ADNOC's approved vendor list. The contract presented exceptional manufacturing challenges, involving steel pipes with a maximum wall thickness of 80mm and a minimum diameter-to-thickness ratio of 15.2. These specifications demanded extreme precision in welding, forming, and dimensional control, alongside rigorous process monitoring and acceptance criteria. Facing tight delivery schedules, Ziking held multiple pre-production and progress review meetings, implementing dedicated order tracking, on-site coordination, and third-party quality surveillance to ensure efficient contract execution. All pipes have now passed final inspection and been shipped.

ADNOC is among the world's leading energy and petrochemical conglomerates with extensive hydrocarbon exploration operations, while NPCC is a highly regarded EPC contractor specializing in oil and gas projects across the Middle East. Supported by comprehensive quality and HSE management systems and robust production capabilities, Ziking serves leading domestic and international oilfield operators. The successful delivery of these JCOE products with ultra-low D/t ratio marks another milestone in Ziking's provision of manufacturing services to the Middle Eastern hydrocarbon sector.
