In recent years, offshore wind power, an important part the Longyuan Zhenhua 3 with a lifting capacity of 2,000 tons.
of the world's clean energy development, has stepped into As the world's leading wind power installation platform, it is
a period of rapid development in recent years. Especially in a multi-functional platform integrating offshore piling, lifting
order to achieve the goal of "peak carbon dioxide emissions and transportation, engineering installation and wind farm
and carbon neutrality”, offshore wind power will usher in a maintenance. "Longyuan Zhenhua 3" can operate in muddy and
bright prospect. Due to the complex and changeable operation sandy waters within water depth of 50 meters and is equipped
environment at sea, the transportation and installation of with DP1; it can operate in standing or floating status; its tail
equipment requires high reliable equipment with high operation crane is up to 1,500 tons. It has a deck area of 3,000 square
ability. Therefore, the self-elevating wind power installation meters, and can carry 3 sets of 6 MW wind turbines or 2 sets
platform, as a "secret weapon", emerges at the right moment. of 8 MW wind turbines, which can meet the area requirements
As early as in 2009, ZPMC began to enter the field of the owner when operates in the wind farm to the greatest

capacity of wind turbine is also gradually increasing, so the lifting position in the field of wind power platform design in China.
capacity of the installation platform must be improved to meet the ZPMC is also keenly aware of the operation and
new market demand. Due to the requirement of high accuracy maintenance needs of offshore wind power, and the next era of
offshore installations, ZPMC team designed the DP1 dynamic offshore wind power will focus on operation and maintenance.
