Abstract

The suction bucket jacket foundation has become a widely choice for supporting offshore wind turbines. Assessing the installation of the suction bucket foundation (SBF) is important as it significantly affects the stability of the offshore wind system and the overall project cost. Currently, experience with suction bucket jacket foundation installations primarily revolves around stiff clay and dense sand, drawing insights from North Sea projects (e.g. the design method reported by DNV-RP-C212). However, there is a shortage of publicly available knowledge concerning SBF installations in the South China Sea, characterised by deep-covered mud (i.e. very soft clay) and extensive layered soils. Existing design parameters may not adequately address these challenges, highlighting the need for a site-specific installation design method. This study introduces a tailored approach for evaluating design parameters of the SBF installation in the seabed conditions of the South China Sea. Utilising field data from 19 suction bucket jacket installations across the region, the proposed method undergoes rigorous validation and testing. The findings of this study aim to contribute to the advancement of offshore SBF installations in the intricate geological setting of the South China Sea. By presenting the SBF installation design method, the research offers practical guidance for both the evaluation of suction bucket jacket foundation installations and the optimisation of turbine locations in the region.

评估中国南海的吸水桶夹套地基安装：实地安装经验的启示

吸水桶夹层基础已成为支撑海上风力涡轮机的广泛选择。吸水斗地基（SBF）的安装对海上风力发电系统的稳定性和整个项目的成本有重大影响，因此对其进行评估非常重要。目前，吸水桶夹套地基的安装经验主要来自北海项目（如 DNV-RP-C212 报告的设计方法）中的硬粘土和密砂。然而，有关南海 SBF 基础安装的公开知识却很匮乏，南海的特点是深厚的淤泥（即非常软的粘土）和广泛的层状土壤。现有的设计参数可能无法充分应对这些挑战，因此需要一种针对具体地点的安装设计方法。本研究介绍了一种量身定制的方法，用于评估南海海底条件下的 SBF 安装设计参数。利用该地区 19 个吸油桶夹套装置的现场数据，对所提出的方法进行了严格的验证和测试。本研究的结果旨在为在中国南海错综复杂的地质环境中推进海上 SBF 安装做出贡献。通过提出 SBF 安装设计方法，该研究为吸水斗护套基础安装评估和该地区涡轮机位置优化提供了实用指导。
