The Sea-Swallows Engineering Tool (SeaSwallowsTool) is a new engineering tool that delivers fast and accurate predictions of nonlinear wave loading on monopile-type offshore wind turbine foundations. It is developed by a consortium led by the Universities of Bath, Oxford, and Strathclyde, and is one of the outcomes of the EPSRC project, Severe Storm Wave Loads on Offshore Wind Turbine Foundations (Sea-Swallows).

The tool is available as a binary executable compiled for Windows, macOS or Linux-based 64-bit operating systems.
