Offshore staff

NORWICH, UK – Acteon subsidiary Menck will supply CCCC 3rd Harbour with a hammer spread to support the company’s activities for offshore wind farms in China.

CCCC 3rd Harbour purchased its first hammer from Menck for foundations engineering in 2016.

The MHU4400S is equipped with a one-piece anvil design, 8 m in diameter.

“The demand for bigger hammers and bigger pile adaptions is growing, and I am confident that both 3rd Harbour and Menck will work together to provide technology solutions to this industry today and in the future,” said Frank Köhrmann, general manager with Menck.
