China’s Oil Storage Construction: An In-Depth Guide

China’s oil storage industry is undergoing significant transformation, driven by the need to enhance capacity and ensure energy security. With the world’s second-largest oil consumption, China’s oil inventories provide crucial insights into global demand dynamics. This guide explores the current state of China’s oil storage, the types of storage facilities, and the technical features that define them.

Overview of China’s Oil Storage Industry

China has embarked on an ambitious campaign to expand its oil storage capacity. The country currently operates over 600 terminal locations with nearly 16,000 tanks dedicated to petroleum products and chemicals. These facilities are primarily located along the coast and in major industrial hubs like Dalian, Tianjin, and Qingdao. The storage market is dominated by state-owned enterprises, with the top five operators controlling 70% of the capacity.

Technical Features of Oil Storage Facilities

The technical specifications of oil storage facilities are critical for understanding their operational efficiency and safety. Below is a comparison of key technical features of different types of oil storage facilities in China.

Feature	Above-Ground Storage Tanks	Underground Storage Tanks
Construction Cost	Higher (20% more)	Lower
Operating Cost	Higher (50% more)	Lower
Land Usage	Requires more land	Requires less land
Safety	Moderate risk	High safety
Environmental Impact	Higher risk of spills	Lower environmental risk
Maintenance	Regular maintenance needed	Minimal maintenance (50 years)
Storage Capacity	Limited by surface area	Greater capacity due to depth

Types of Oil Storage Facilities

China employs various types of oil storage facilities to meet its growing demand. The following table outlines the primary types of storage and their characteristics.

Type	Description	Advantages	Disadvantages
Above-Ground Storage Tanks	Large tanks located on the surface, commonly used for crude and refined oil.	Easier access for loading/unloading	Higher risk of environmental spills
Underground Storage Tanks	Cavernous tanks built underground, designed for long-term storage.	Safer, lower costs, less land use	More complex construction
Bonded Storage Tanks	Facilities that allow for tax-free storage of imported oil.	Cost-effective for importers	Limited to specific locations

Current Trends and Developments

In recent years, China has seen a surge in crude oil inventories, particularly during the COVID-19 pandemic. The country capitalized on low oil prices, increasing imports significantly. Major ports faced congestion, leading to longer wait times for tankers. As of 2021, China’s oil purchases are influenced by the availability of spare capacity and ongoing construction of new storage facilities.

The Daxie underground commercial oil reserve project, initiated in December 2022, exemplifies China’s commitment to expanding its storage capabilities. This facility, located in Ningbo, will feature a 3 million-cubic-meter underground cavern tank, enhancing the country’s ability to manage its oil supply effectively.

The Role of Independent Players

Interestingly, independent storage operators are gaining ground in China’s oil storage market. Companies like Vopak and Oiltanking are contributing to the expansion of storage capacity, with 15 out of 26 new projects being led by independent players. This shift indicates a more open market, allowing private companies to participate in a sector traditionally dominated by state-owned enterprises.

Conclusion

China’s oil storage industry is at a pivotal point, with significant investments in new facilities and technologies. The expansion of both above-ground and underground storage options is crucial for meeting the country’s energy demands and ensuring stability in the global oil market. As China continues to build its storage capacity, it will play a vital role in influencing oil prices and supply dynamics worldwide.
