How It Works Precision machining
Precision machining
For critical support structures
Sea fastening is a steel structure used to secure wind turbine components on installation vessels. Similar support structures are used at fabrication facilities and shipping ports, where towers, nacelles, and other components are stored before installation. These include tower stands and transport frames, which serve as critical interfaces between the support structure and the component itself.
For tower and nacelle applications, these interfaces often consist of large flange connections that must meet precise tolerance requirements. Achieving these tolerances is essential for efficient assembly and reliable positioning of the supported component.
CNC Onsite performs precision machining of sea fastening systems, tower stands, and transport frames throughout the project lifecycle—from fabrication and production facilities to shipping ports and installation vessels. Using Goliath and our mobile machining systems, we machine flanges and mounting surfaces directly where the structures are located, eliminating unnecessary handling and transportation while ensuring precise, repeatable results.
The result is a flexible machining solution that delivers fine tolerances, improved efficiency, and controlled quality across large support structures.
