FRANKFURT, July 7 (Reuters) - Orsted Orsted, the world's largest developer of offshore wind power farms, is launching the sale of Hornsea Two in a deal that is expected to value the British offshore wind park at roughly 3 billion euros ($3.54 billion), including debt, people close to the matter said.

Orsted is working with Credit Agricole on the partial divestiture.
