Everyone is more lively and the ocean is more exciting with you. Everyone is welcome to participate in more forum exchanges and discussions.----------------------------------------------------------------Ocean engineering equipment is* * A strategic emerging industry, the hydraulic submersible pump system is a key equipment for liquid cargo ships such as FPSO, product oil tankers, chemical tankers, etc. It is a pumping system that realizes the external transportation of liquid cargo, and has functions such as liquid cargo unloading and cabin cleaning. Due to its extremely high requirements for safety, reliability, and system integration, its key technologies such as high-efficiency hydraulic component design, high-pressure and large-flow debugging valve design, power unit shock and noise reduction, product health status monitoring, and product testing have never been conquered, and the domestic and foreign markets have always been monopolized by foreign companies. On July 30, 2019, Wuhan Marine Machinery’s domestic submersible pump system for CNOOC Liuhua 16-2FPSO successfully rolled off the production line after completing various tests to simulate real ship working conditions. After testing and verification, the product performance is stable and reliable, and major technical indicators such as unloading efficiency and energy consumption have reached the level of internationally advanced products. On July 31, under the leadership of China Shipbuilding Industry Corporation and CNOOC, relevant leaders and industry experts gathered at Wuhan Marine Machinery to witness the acceptance of the localization results of the submersible pump system.
During the design and development process, Wuhan Marine Engineering started from the construction of technical system to conduct research on the reliability of submersible pumps. The first is to benchmark the international first-class hydraulic submersible pump system, from the overall hydraulic submersible pump system, submersible pump, hydraulic system, electrical system, system accessories, etc. to benchmark the technical parameters of the international hydraulic submersible pump system to form a benchmark data table. The second is to carry out system reliability design, analyze the failure modes and failure causes of the hydraulic submersible pump system, submersible pump, hydraulic system, and electronic control system, propose detailed control strategies for each failure cause, and form a control strategy table. The third is to build a product testing system around the core technology of hydraulic submersible pump products and establish a stable and complete hydraulic submersible pump technology chain. Focusing on the hydraulic submersible pump system products, a core technology system with independent intellectual property rights has been established, forming the "Hydraulic Submersible Pump System Core Technology Catalog and Patent Plan". Based on the core technology system, a series of patented technologies have been formed around a number of core technologies such as overall integration, pump unit structural design, hydraulic design, seal leakage monitoring, and system installation and layout methods. More than 40 patents have been applied for and accepted (including more than 30 invention patents). Fourth, relying on Wuhan ship machinery and marine engineering electromechanical equipment * * The innovative advantages of the engineering laboratory have built a new closed-circuit high-precision hydraulic model test bench, and renovated the liquid cargo product manufacturing plant starting from digital and intelligent manufacturing to provide guarantee conditions for product development. In the end, the test results of the hydraulic system and electronic control system of the submersible pump were qualified. All functional tests and performance tests of the WHP100, WHP200, WHP250, and WPP150 submersible pump products met the design requirements and passed the BV classification society inspection. The domestic submersible pump system's technical indicators such as unloading rate, hydraulic parameters, head, and efficiency are equivalent to similar foreign products, and some functions are superior to foreign products.
