Three-Pile Offshore Wind Turbine Foundation Introduction
This project develops a parametric model of a three-pile offshore wind turbine foundation using Dynamo BIM. The model explores how key geometric parameters influence material usage and simplified stability measures under varying water depths.

Model Logic

The foundation consists of three hollow steel piles arranged in an equilateral triangular layout and connected by a simplified deck plate. The model is fully parameterized, allowing dynamic adjustment of water depth, pile radius, wall thickness, pile spacing, and deck dimensions. Changes to any parameter automatically update the geometry and material quantities.

Performance Criteria

Three configurations representing shallow, medium, and deep water conditions were generated.
-The shallow-water case shows high material efficiency but lower stability.
-The deep-water case requires more material and exhibits increased slenderness.
-The medium-depth configuration provides the most balanced performance, combining moderate material demand with acceptable global and bending stability.

Design Scenarios and Key Findings

Three configurations representing shallow, medium, and deep water conditions were generated.
-The shallow-water case shows high material efficiency but lower stability.
-The deep-water case requires more material and exhibits increased slenderness.
-The medium-depth configuration provides the most balanced performance, combining moderate material demand with acceptable global and bending stability.

Conclusion
The parametric model demonstrates how geometric and environmental parameters interact in offshore foundation design. By enabling rapid generation and comparison of design alternatives, the model supports informed decision-making at the conceptual design stage.
