Huan Qiu Wang·2026-01-02 06:36Core Insights - China's largest offshore gas field "Deep Sea No. 1" has completed its 100th oil export operation since production began, with an expected annual output of over 4.5 million tons of oil equivalent by 2025, comparable to that of a medium-sized onshore oil field, indicating that China's deep-sea gas field production and operation technology has reached world-class standards [1][7]. Production and Export Operations - "Deep Sea No. 1" produces 5 billion cubic meters of natural gas annually, along with over 400,000 tons of condensate oil as a byproduct [7]. - The condensate oil is stored in four pillars surrounding the platform, each equipped with a storage capacity of 5,000 cubic meters [7]. - The oil is temporarily stored in the pillars and then transported via a shuttle tanker to onshore refineries for further processing [7]. Export Logistics - The condensate oil export hose measures 220 meters in length, with a maximum export capacity of nearly 15,000 tons, and exports occur approximately every 12 days [9]. - The project team employs a shuttle tanker equipped with an advanced dynamic positioning system to ensure safe oil transport in complex sea conditions [11]. Technological Advancements - The "Beihai New Hope" shuttle tanker, designed specifically for the "Deep Sea No. 1" project, is the first domestic dynamic positioning shuttle tanker, measuring 137 meters in length and capable of carrying up to 15,000 tons [13][15]. - This vessel represents a breakthrough in China's capabilities in the design, construction, and operation of high-end special vessels, previously dominated by foreign companies [15]. Industry Impact - The successful construction and operation of the "Beihai New Hope" has enabled China to master core technologies related to dynamic positioning shuttle systems, which will facilitate the application of these technologies in domestic deep-water oil and gas projects and promote Chinese enterprises and technologies in the international market [17].
