July 3，Floating wind power platform with the largest single capacity in the world“Mingyang Tiancheng”The installation was officially completed in Nansha, Guangzhou，This is also the first offshore wind power platform in the world to install two wind turbines on a floating foundation.，Total capacity up to 16.6 MW。The external cable system of the wind power platform is designed and developed by Liugong Owim Company.、Manufacturing and implementation of installation construction。

“Mingyang Tiancheng”The cable system outside the wind power platform consists of 13 groups of main cables.。Because“Mingyang Tiancheng”To work in a deep-sea environment.，Therefore, higher requirements are put forward for the performance of the cable.。First，The strong corrosivity of the deep sea environment requires the cables to have extremely high corrosion resistance，Ensure that the cable can operate stably for a long time under harsh conditions.。Secondly，Upwind cables are subjected to water pressure from 20 to 30 meters of seawater，And dynamic seal performance is satisfied，In order to resist the impact of seawater infiltration on structural safety.。And，Deep-sea wind power projects put forward strict requirements for 25 years of maintenance-free.，This requires the cable to be maintained，It can still ensure a service life of up to 25 years.。

It took two years，Liugong Owim Company and“Mingyang Tiancheng”The R & D team has successfully developed a floating offshore wind power cable system with high anti-corrosion performance requirements for deep-sea environment.，And that super-large specification of the finis cable is formed.（ST15-67）Forked lug fatigue test、Can withstand 0.3MPa（30mDepth of water）Full-sealing structure of wat pressure inhaul cables、Adaptive universal adjust rigid spacer、Five innovative technologies, such as large swing angle dynamic sealing, integral sealing and sea segmental cable anti-collision structure.，Declare 12 patents。The new technology forms a comprehensive protection from the cable body to the anchor head.，Meet the requirements of corrosion resistance in deep sea environment，Achieve dynamic sealing under 30 meters of water pressure and 25 years of maintenance-free design requirements，To ensure the stability and safety of deep-sea cables。

In addition，The installation of tension system cable on wind power platform is different from the common bridge cable construction.，The process is complex，Extremely difficult，There is no successful experience to draw lessons from in the world.。The construction team of Liugong Owim aims at the particularity of the project.，A detailed special technical scheme has been formulated.，The layout of large temporary structure facilities including the cableway manned hanging basket system and the layout of intelligent tensioning system are mainly studied.，Optimize and modify according to the site environment and conditions in the implementation process.。

This project has very high requirements for cable force and tension synchronization.，For this reason，Liugong Owim Company has specially developed the synchronous phase control intelligent tensioning system.，Preload by stages、Multidimensional monitoring、Ynchronous tensioning and other mean，Accurately control the tension value，Ensure synchronism during cable tensioning，Make 13 groups of main cables reach their respective design pre-tightening force at the same time。And，Each group of cables is equipped with a health detection system for real-time cable force monitoring.，Mutual check of the two data，Ensure the accuracy of the final cable force。

Liugong Owim's floating offshore wind power cable system includes cable product system.、Monitoring system、Construction system、Product production process、Test process，All through the China Classification Society.(CCS)On-site certification，You can go to sea with a certificate，It is the only one in the industry at present.CCSCertified prestressing enterprise。
