随着海上风电机组大兆瓦趋势不断增强，海上风电基础重量和尺寸也随之增加。成本最低、应用最为广泛的单桩基础，从2015年的500~700t（4MW），发展到如今的3000t（16MW），甚至未来会出现5000t的超重单桩基础。在传统的海上风电单桩基础施工工艺中，海上风电浮吊装备已经无法满足施工吊重要求。在此背景下，本文研发出气囊助浮技术。因其成本低、操作简便、可减少吊机负荷的优势，成为未来超重单桩（3000~5000t级）的潜在解决方案。本文详细探讨气囊助浮技术的理论基础、工艺设计及其优势，介绍了其在海上风电单桩基础施工中的应用及前景。研究表明，气囊助浮技术在提高施工效率、降低成本和减少环境影响方面具有显著优势，能够达到“小船干大活”的效果，未来在海上风电领域具有广阔的应用前景。

In light of the rapid development of offshore wind power， more economically efficient construction techniques are required. Traditional heavy-duty maritime cranes in construction face high costs and significant risks. On the other hand， the balloon-assisted floatation technology， with its low cost， ease of operation， and ability to reduce crane loads， presents itself as a potential alternative. This article provides an in-depth exploration of the theoretical foundation， technological design， and advantages of balloon-assisted floatation technology， elucidating its potential application prospects in offshore wind turbine single pile foundation construction. Research has shown that the balloon-assisted buoyancy technology offers significant advantages in terms of enhancing construction efficiency， reducing costs， and minimizing environmental impact. It is poised for broad applications in the offshore wind sector in the future.
