ITW teams have successfully completed the last grouting operation at Amrumbank West Offshore Wind Farm in Germany.
The connections between transition piece and monopile have been grouted with the cementitious-based material Ducorit.
According to the company, for the Amrumbank project (80 connections), ITW delivered another turnkey grouting solution including Ducorit, its newly developed equipment and with the installation of the product performed by its own supervisors.
In 2014 the first 19 connections were grouted while the rest of the 61 connections were completed in the period April 19 to May 21, 2015 with an average of 2 grouting operations per day.
The installation of the monopiles and transition pieces was performed from the jack-up crane vessel MPI Discovery and the grouting part executed from Far Sapphire a DP2 grouting vessel equipped with an Ampelmann system.
“We do not prefer one solution rather than the other but at this project it has really worked out well”, says Soren Munk, ITW Supervisor and he continues, “It has been a pleasure working on the Amrumbank project. The setup allowed us to work very intensively for a shorter period.”
Amrumbank West is a 288MW offshore wind farm being developed in the North Sea, Germany. The wind farm will include 80 Siemens SWT-3.6-120 wind turbines rated at 3.6MW each. The turbines will be installed over an area of 32km² in water depths ranging from 20m to 25m. It is located 35km north of Helgoland and 37km west of Amrum .
