The Brunei petrochemical project is an important node project in the "Belt and Road" initiative. In this major project, the key construction tasks undertaken by COOEC played a decisive role in the smooth operation of the entire project, while the application of CDSR oil hoses became an important technical support for ensuring the safe and efficient progress of the project.
The Brunei petrochemical project is located in an offshore oilfield development area, and the oil transportation system needs to face multiple influences such as seawater environment, tidal stress, temperature changes and fluid chemical composition. Conventional hoses may be affected by internal and external corrosion, localized wear, or mechanical damage during long-term service, thereby increasing the risk of leakage and maintenance costs. To improve system reliability and extend service life, CDSR 24’’ double carcass oil hose was selected as the solution for the oil string trunk line.
As a company with over 50 years of experience in rubber product manufacturing, CDSR has long been focused on providing high-quality fluid engineering hoses for the global marine energy transmission industry. Its 24’’ double carcass oil hose design is ingenious, adding a secondary carcass to the standard primary carcass.
This design effectively accommodates the transported medium that overflows from the primary carcass due to slow leakage or sudden failure, greatly improving the safety and environmental friendliness of the oil transportation process. Meanwhile, the oil hose is also equipped with a highly efficient and reliable leak detection system that can monitor the hose's operation in real time. If any abnormality occurs, operator can quickly take countermeasures.
In the Brunei petrochemical project, the CDSR 24’’ double carcass oil hoses were mainly used in two 24’’ double carcass floating oil hose strings and two 24’’ submarine oil hose strings. In floating oil hoses applications, the excellent flexibility and weather resistance enable CDSR floating oil hoses to adapt to complex and ever-changing marine environments. Whether facing the impact of waves or the corrosion of seawater, these hoses can operate stably and ensure the efficient transportation of crude oil. In the submarine oil hoses section, due to the excellent pressure resistance and sealing performance, CDSR submarine oil hose can ensure the safe and continuous transportation of crude oil under high pressure, effectively avoiding risks such as crude oil leakage.
The successful application of CDSR 24’’ double carcass oil hose in Brunei petrochemical project is of profound significance. It not only effectively promoted the smooth implementation of the project and ensured the supply of crude oil for petrochemical production, but also demonstrated China's technological strength and innovation capabilities in the field of offshore oil engineering equipment.
At the same time, this application case has earned CDSR a good reputation in the international market and provided valuable experience for more similar projects in the future. This will help China's offshore oil engineering industry move steadily forward in the Belt and Road Initiative and further strengthen energy cooperation and economic exchanges with countries along the route.
