QYSEA’s One-Stop Offshore Wind Power Solution: Contributing to the Global Goal of Carbon Neutrality QYSEA’s One-Stop Offshore Wind Power Solution: Contributing to the Global Goal of Carbon Neutrality

As the country pays more and more attention to issues surrounding energy conservation and environmental protection, wind energy has garnered growing importance as a clean and renewable global power source. Under China's '30·60' decarbonization goal, renewable energy -especially wind power- is on course to become the nation's mainstream energy source, a vital path in lowering carbon emissions and eventually achieving the goal of carbon neutrality.


01 World Leader in Offshore Wind Energy Development


Incentives to innovate, tax reductions, financial subsidies... the implementation of these support policies and measures have led to the comprehensive recovery of the nation's marine-based economy. In particular, the rapid development of marine-based energy sources has become an essential pathway in achieving China's dual-carbon goals.

To achieve carbon neutrality, we must first reduce the use of coal-based thermal power in exchange for clean and renewable energy sources, such as solar, nuclear, wind, and hydro power.


Offshore wind power essentially relies on natural winds to generate energy. In recent R&D breakthroughs, the implementation of a smart grid is one of the technologies which will help the wind industry to effectively use wind power plants and reduce the cost of operation and maintenance, with the first domestic intelligent wind farm being connected to the grid in the Jiangsu province.

China has become the world's second-largest wind power market in recent years. According to the latest data, the country's new offshore wind power capacity has led the world for three consecutive years. As of the end of June 2021, the cumulative installed capacity of offshore wind power throughout the nation has exceeded 11.1 gigawatts. The International Energy Agency predicts that China’s installed offshore wind power capacity will be equivalent to that of the EU by 2040, and where emission reduction capabilities will be further improved.


02 Challenges in Traditional Operational Methods of Offshore Energy


As an emerging industry, offshore wind power is almost is limited in terms of a solidified guide to underwater operations and maintenance. After the rush to install many of these structures in recent years, there will inevitably be various structural problems that will appear. Only through frequent professional inspections and assessments is it possible to maintain the structural quality and avoid any major issues.

Offshore wind power operation and maintenance tasks are mainly divided into inspections of monopile frames, pile foundations, structural scours, submarine cables, and more. The traditional method of assessments would mainly involve sending divers into the dark and narrow spaces to operate, which is costly, timely, as well as risky.



Main Factors & Challenges of Traditional Operating Methods

Environment: The underwater working environment is complex and unpredictable, resulting in potentially harmful risks for divers during their operations.

Time: In addition to human risks involved, the time and energy required for each dive are not optimal and likely to result in delays and added costs to the project.

Data: At present, underwater construction operations are lacking real-time feedback visualizations and data collection systems. In addition, the ability to make collective decision-making is limited.

Led by QYSEA, the industry has seen underwater robots are equipped with high-definition cameras and sonar systems to provide first-hand information for workers onshore to help assess the engineering accuracy, improve the engineering efficiency, and reduce construction costs of the project.
