Driven by the dual strategies of energy security and core technology autonomy, Saisi's high-performance chips and atomic clocks have deeply empowered CNOOC's deep-sea exploration, accelerating the unlocking of billion-ton oil and gas fields.

The oil and gas circle has expanded again, and Saisi has completed the business layout of the "Three Oil Giants".

In this field, Saisi uses high-precision "clock synchronization" as a strategic fulcrum to deeply empower the "Three Oil Giants" - CNOOC, Sinopec, and CSG - from land-based refining and chemical production to deep-sea exploration application scenarios.

The early land-based breakthrough - the "Three Oil Giants" used Saisi's timing system to achieve full-link high-precision time synchronization; now the deep-sea breakthrough - CNOOC's deep-sea underwater exploration equipment is equipped with Saisi's high-performance chip atomic clocks.

Saisi's high-performance chip atomic clocks help CNOOC unlock billion-ton oil and gas fields.

As global oil and gas exploration advances into "deepwater and ultra-deepwater", the deep sea has become a new battlefield in the energy competition among major countries. As the main force in China's deep-sea oil and gas exploration and development, CNOOC has already discovered five oil and gas fields over 100 million tons in the Bohai Sea and South China Sea in the past 24 years.

In the development of deep-sea oil and gas fields, the time synchronization accuracy of deep-sea underwater nodes directly determines the accuracy of seismic wave data and the efficiency of oil and gas resource positioning. The time synchronization error between deep-sea underwater nodes needs to be controlled within the microsecond level; otherwise, it will lead to signal distortion and affect the accuracy of layer imaging.

As a benchmark enterprise for clock synchronization, Saisi has customized high-performance chip atomic clocks for CNOOC. This atomic clock is a micro atomic clock based on the coherent population trapping principle and MEMSA technology, which can output an accurate and stable 16.384 MHz standard frequency signal and 1PPS pulse signal to the deep-sea underwater node equipment.

At the same time, the product adopts an anti-pressure and corrosion sealing design, which can work normally within the temperature range of -10℃ to +70℃, highly adapting to the high-pressure environment of the deep sea; it has ≤130mW low power consumption and ultra-stable performance, which can ensure the array synchronization triggering of deep-sea underwater sensors and effectively reduce the error rate of exploration data.

After more than ten years of deep involvement in the field of clock synchronization, Saisi has laid out a comprehensive strategy from high-performance key components (clock chips, crystals, atomic clocks) - complete equipment (NTP/PTP time synchronization servers, time synchronization devices, timing security protection devices, time frequency testers, etc.) - end-to-end solutions for the entire industry, achieving multi-dimensional scene coverage from land to airspace to deep sea.

In the future, Saisi will continue to adhere to the concept of "leading time and frequency manufacturing, creating a precise world", providing more comprehensive products and solutions for thousands of industries in society, solving the problem of time and frequency reference. At the same time, it will extend the cooperation chain and expand the business chain, promoting the expansion of Saisi's "circle of friends" in thousands of industries.
