The offshore operating environment of the oil and gas industry is complex and harsh. From deep-sea mining to ocean transportation, every link is inseparable from the precise control of the motion state and the stable control of fluid delivery. Motion and flow control solutions are not only the core to ensure operational efficiency, but also the key to preventing safety risks and protecting the marine environment. With its full range of high-quality offshore mooring oil suction and discharge hoses, CDSR provides professional solutions in this field that meet international standards and combine performance and safety.
Industry demand: "double test" in harsh environment
In offshore oil and gas transportation scenarios, the core demands of flow control are reflected in two aspects: efficient transportation and safety protection. On the one hand, the hose needs to maintain structural stability under a certain pressure and high flow rate to ensure the continuous transportation of crude oil and liquefied petroleum products; On the other hand, it is necessary to resist external erosion such as seawater penetration, ultraviolet aging, wind and wave wear, while preventing environmental and safety accidents caused by internal medium leakage.
Especially in highly integrated offshore facilities such as FPSO, FSO, CALM, and SALM, this requires the hose to not only have high-strength structural support, but also multi-dimensional weather resistance and safety redundancy design.
CDSR solution: technical response to adapt control needs
CDSR's oil suction and discharge hoses for offshore moorings, with its design concept and technical characteristics, accurately responds to the core needs of motion and flow control:
From the perspective of motion control, CDSR products have designed differentiated structural solutions for different scenarios. For example, the minimum bending radius of submarine hoses is 4 times the nominal diameter, and that of floating hoses is 6 times, ensuring that the pipelines can flexibly adapt to the movement trajectory in dynamic environments such as waves and ship swaying, and will not cause structural damage due to excessive bending. The layered design of single carcass and double carcass (such as the "primary carcass + second carcass" structure of the double carcass) further enhances the tolerance to complex motion states and maintains overall integrity even under sudden deformation.
In terms of flow control, CDSR oil hose ensures the stability of fluid transportation with multi-dimensional performance. Its rated pressure levels of 15 bar, 19 bar, 21 bar and higher are suitable for the pressure requirements of different delivery scenarios; The NBR rubber lining can withstand a variety of hydrocarbons, ensuring that the medium can still effectively resist medium corrosion and erosion wear at high-speed flow (up to 21 m/s); The "pressure-compensated leak detection system" equipped in the double carcass series can monitor flow abnormalities in real time and trigger an early warning when a trace leak occurs, thus controlling risks at the source.
The CDSR oil hose series fully complies with the requirements of "Guide to Manufacture and Purchasing for Offshore Mooring" (GMPHOM 2009), is designed and manufactured under the ISO 9001 quality management system, and is certified by BV and DNV, ensuring reliable response to motion and flow control needs from the source of production.
