Abstract

  In order to study the strength and the effectiveness of reinforcement measure of offshore flexible direct current converter valve during marine transportation, a finite element model of offshore flexible direct converter valve was established, and the dynamic response of the converter valve during marine transportation was studied combining with its own vibration characteristics, and the vibration reduction effect after the reinforcement measures were analyzed. The results show that there is a large displacement at the top terminal of the weak axis direction of the two single towers before and after the connection of the converter valve. After the reinforcement measures are taken along this direction, the displacement in the same direction is significantly reduced, and the stress of each part is further reduced on the basis of meeting the safety requirements, and the reinforcement measures are effective.
