PO181: BUOYANCY-ASSISTED INSTALLATION: Upending and Lowering Monopiles with Reduced Crane Load
Bas van Wuijckhuijse, R&D Manager, TWD
Abstract
As offshore wind projects scale up in size and complexity, traditional monopile (MP) installation methods are reaching their operational limits. Larger turbines, deeper waters, and less favorable soil conditions are driving the need for heavier MPs, which challenge the lifting capacities of existing installation vessels and cranes. In the coming decade, only half of the target MP installations may be achievable due to limited asset availability. This abstract introduces Buoyancy-Assisted Installation (BAI), a novel approach that leverages the natural buoyancy of MPs to reduce crane dependency and expand the pool of viable installation assets. By sealing, pressurizing MPs or using external floatation devices, significant lifting forces can be generated, enabling more efficient and flexible transport and installation strategies. Several methodologies are presented; each tailored to specific project conditions. These methods demonstrate how BAI can reduce crane loads by up to 50% while maintaining sound workability. Ultimately, there is a novel concept which can upend a MP without the use of a crane. This craneless method, in particular, offers a scalable solution for future ultra-heavy MPs, using ballasting and external moments to achieve vertical positioning without cranes. Main focus of this presentation lies on the floating MP installation method. While BAI is not a one-size-fits-all solution, the technology is widely applicable and can help overcome current logistical and technical barriers, ensuring continued progress toward global renewable energy targets.
