OSLO, May 25 (Reuters) - Equinor on Wednesday submitted a plan to develop a cluster of gas and condensate discoveries in the Norwegian Sea for 9 billion Norwegian crowns ($940 million), part of a rush of new petroleum projects expected in Norway this year.

Halten East contains reserves of around 100 million barrels of oil equivalent, 60% of which is natural gas, and is expected to begin exporting to Europe in 2025, Equinor said.

Operator Equinor holds a 57.7% stake while Vaar Energi holds 24.6%, Spirit Energy 11.8% and Norway's Petoro 5.9%. ($1 = 9.5715 Norwegian crowns) (Reporting by Nerijus Adomaitis, writing by Terje Solsvik, editing by Gwladys Fouche)
