Soft starters for the Offshore Oil & Gas Industry

Floating crane
Motor ratings: 6.3kV, 250A
Multi-Start- soft starting 2 thrusters

The Shanghai Zhenhua Port Machinery co. was contracted by the Shanghai Salvage Bureau of the Ministry of Communication of the Peoples Republic of China to build a floating crane.

With 2 medium voltage thrusters to start during complex operations, the contractor turned to Solcon for the most dependable soft-starting solution available to ensure continuous performance under intensive and adverse conditions of constant vibrations, temperature variations and corrosive environmental conditions, eliminating the current inrush that causes severe voltage drops.

The choice of Solcon soft starters for motors allows engineers to design with smaller generating capacity, since the inrush current is eliminated thereby reducing the necessary total installed power.
