Siemens will deliver 48 SWT-3.0-108 turbines to the project, which will be installed at the Ijsselmeer artificial lake. They will be placed between 500 metres and 1,100 metres from the northern and western dike in shallow waters.
The announcement comes as the project's owner says it has reached financial close. It has agreed a EUR 320 million deal with a consortium of banks, led by ING and Rabobank.
Dutch-utility Eneco has signed a 15-year power purchase agreement with the owners.
Installation will begin in 2015 with a planned commissioning date in early 2016.
In 2013, the German manufacturer was appointed turnkey contractor for the project, meaning it is also responsible for supplying the transformer station and will operate it for a minimum of 15 years.
Dutch firms Mammoet and Ballast Nedam were awarded the contracts to transport and install the turbines and produce foundations for the project.
The 144MW Westermeerwind project, north of Amsterdam, is the country's largest near-shore wind project. It is next to the Noordoostpolder onshore wind farm, where a further 38 Enercon 7.5MW turbines will be erected along the dike.
Siemens has also handed a cabling contract for the project to Dutch firm VSMC. The cabling specialist will 48 inter-array cables and six export cables to connect the turbines to the onshore substation. Cable installation is due to begin in April 2015.
