Under the guidance of the “two-carbon” strategy, the global energy industry structure is rapidly reshaping, and offshore wind power has become a powerful starting point to promote energy transformation. With the vigorous development of China’s offshore wind power industry, the scale of operation continues to expand, and the new installed capacity has broken records repeatedly. Wind farm construction to the deep sea, the large-scale unit, equipment integration has become the inevitable trend of offshore wind power installation.

However, faced with wind, ocean currents, sea fog and other extreme weather, the difficulty of offshore construction operations has increased sharply. The far-reaching sea environment farther offshore and deeper waters also puts forward higher requirements for the stability and reliability of the core equipment of wind power installation ships.

In June, the 1200T jack-up wind belt installation ship of Huaxia Jinrent Shenda 01 and 02 was successfully launched. With a total length of 106.6 meters, a width of 44.2 meters and a depth of 8.45 meters, the design draft is 5 meters, the maximum operating water depth is 60 meters, and the maximum lifting height is 185 meters, which is suitable for navigation and operation requirements in unlimited navigation areas. The platform has DP-1 dynamic positioning and is equipped with a high-power electric propulsion device, which can move freely between wind fields. The two platforms can cover the installation of 16MW offshore wind power units, and are currently the deepest operating water depth, the longest pile leg, the highest floating crane lifting height, the most complete function and the highest efficiency of cylindrical pile leg wind power installation platforms in China.

Huichuan Technology provided AFE type water-cooled electric propulsion frequency converters for the whole ship of Huaxia Gold Lease No. 1 and No. 2, including 2 sets of 2000KW main propulsion water-cooled frequency converters and 2 sets of 1400KW bow propulsion water-cooled frequency converters. During the trial of ship 1, the water-cooled inverter worked at full load and experienced numerous tests, escorting the exploration of Chinese ships to deeper waters.

It’s called MD880

MD880LC high-performance functional inverter to help China’s Marine automation industry localization upgrade. Among them, AFE low-harmonic water-cooled inverter has become the first choice for Marine and offshore electric propulsion applications.

As a high-end variable frequency speed regulation product technology platform of Huichuan Technology, it supports two modes of air cooling and water cooling. The product is divided into two topological forms of single transmission and multi-machine transmission. It is a drive product that is positioned in high-end transmission, high-performance speed and torque control, high reliability and high power density coverage.
