The present invention relates to a subsea installation for treatment of hydrocarbons from a subsea well, having a pipe system comprising a first manifold (2) connected to at least one well (1) and at least two first pipe segments (3) with an inlet connected to the manifold (2) and where the first pipe segments (3) comprise at least two outlets, where the first manifold (2) and the first pipe segments (3) are arranged in a first plane and where one of the outlets from the first pipe segments leads to a second manifold (7). According to the invention a second of the outlets from the first pipe segments (3) leads to at least two second pipe segments (9) arranged in a second plane and where at least one of the outlets forms an inlet to the second pipe segments (9), where the second pipe segments (9) comprise at least one outlet leading to a third manifold (12).
