Striving For The Sea And Heading For The Deep Blue | HZSS's Ultra-Large 18.4mw Dry Gas Compressor Aftercooler Offshore Ship "High-End" "Goes Out To Sea" Again

HZSS Technology has successfully developed and delivered three dry gas compressor aftercoolers (PCHE) with a power of up to 18.4MW for the West Lake area natural gas transmission and terminal facility capacity improvement project of CNOOC (China) East China Sea West Lake Oil and Gas Operating Company.

Overview of the East China Sea West Lake Region Natural Gas Transmission and Terminal Facilities Capacity Improvement Project

According to the East China Sea regional production planning forecast, natural gas production will increase to 7 billion cubic meters in 2025-2026 and maintain long-term stable production. In order to improve the annual pipeline transmission capacity of the West Lake region, it is necessary to build the "West Lake Regional Natural Gas Transmission and Terminal Facilities Capacity Improvement Project", through the construction of a new natural gas booster platform (DH BOP platform), the submarine gas transmission pipeline from the HY1-1CEP platform to the TWT-CEP platform, and the expansion of the Ningbo terminal, to solve the transmission bottleneck and ensure the full release of the 7 billion cubic meters of production capacity and safe production operation.

HZSS Technology provides key equipment to help efficient and safe transportation of natural gas

The natural gas extracted from offshore oil and gas platforms needs to be pressurized before it can be efficiently and safely transported to land terminals through submarine pipelines. After pressurization, the temperature of natural gas often exceeds 120°C, which is much higher than the temperature that the submarine pipeline can withstand. Shenshi Technology PCHE can quickly cool high-temperature natural gas to 40~45°C, providing a guarantee for long-distance submarine pipeline transportation.

Advanced technology, multiple advantages to achieve an ideal solution

Shenshi Technology's PCHE core is made of advanced diffusion welding technology and has multiple advantages such as high and low temperature resistance, small size, and high reliability. It is an ideal solution for natural gas processing on offshore oil and gas platforms.

1. Tolerance to extreme temperatures: The product can operate stably at extreme temperatures ranging from -19°C to 178°C, further improving the safety and production efficiency of the platform.

2. Small size: The volume and weight are only 15% to 20% of the traditional shell and tube heat exchanger, which greatly reduces the platform's floor space and weight load, freeing up valuable space and weight margin for other equipment.

3. High reliability: Shenshi Technology PCHE has fewer welds and less welding, which greatly reduces the possibility of equipment leakage and enhances the reliability of overall operation. This feature is particularly important in the complex and high-risk environment of offshore oil and gas platforms.

Continuous innovation to promote high-quality development of the offshore oil and gas industry

The three PCHEs provided for the East China Sea West Lake area natural gas transmission and terminal facility capacity improvement project integrate Shen's years of technical accumulation and engineering experience, efficient and compact design, and exquisite manufacturing technology, providing strong equipment support for offshore oil and gas development. In the future, Shen's Technology will continue to uphold the mission of "integration and innovation, ecological technology", give full play to its own advantages, help my country's offshore oil and gas industry develop with high quality, and contribute to ensuring national energy security.
