In view of the problems that the materials used in the deep-water riser vibration suppression device have not been localized, and the supply price and cycle of foreign products are uncertain, domestic products are selected, the formula is determined through experimental design and screening, and sample production and performance testing are carried out at the same time. The test results show that the synthetic materials are tested by American national standards, and the performance is better than that of well-known foreign manufacturers. It is realized that the use of domestic processing equipment and domestic materials can be manufactured to meet the needs of China's far-reaching offshore development for vorticity vibration devices. The spiral plate vortex induced vibration suppression device for deepwater risers consists of structures such as clamps, fins, clamps, grooves, etc. The device with a single pitch length consists of 6 units, and the spiral plate on one device is composed of multiple sets of fins with specific parameter shapes. There is a 60° angular displacement between the card strip and the card slot.

摘要

In view of the problems that the materials used in the deep-water riser vibration suppression device have not been localized, and the supply price and cycle of foreign products are uncertain, domestic products are selected, the formula is determined through experimental design and screening, and sample production and performance testing are carried out at the same time. The test results show that the synthetic materials are tested by American national standards, and the performance is better than that of well-known foreign manufacturers. It is realized that the use of domestic processing equipment and domestic materials can be manufactured to meet the needs of China's far-reaching offshore development for vorticity vibration devices. The spiral plate vortex induced vibration suppression device for deepwater risers consists of structures such as clamps, fins, clamps, grooves, etc. The device with a single pitch length consists of 6 units, and the spiral plate on one device is composed of multiple sets of fins with specific parameter shapes. There is a 60° angular displacement between the card strip and the card slot.
