Claim Text:
1. A subsea deployable counter-rotating compressor for compressing a fluid comprising: a fluid inlet; a perforated structure downstream of the fluid inlet; a manifold downstream of the perforated structure; wherein the fluid inlet, the perforated structure, and the manifold are configured such that the fluid is to flow from the fluid inlet, both through and around the perforated structure, and into the manifold; a first elongated member rotatable about a longitudinal axis and disposed downstream of the manifold; a first plurality of impellers fixedly mounted to the first member and being shaped and arranged so as to exert force on the fluid in a direction primarily parallel to the longitudinal axis when the first member is rotated in a first rotational direction about the longitudinal axis; a second elongated member rotatable about the longitudinal axis and disposed downstream of the manifold; wherein the manifold is configured to distribute the fluid to the first elongate member and the second elongate member; a second plurality of impellers fixedly mounted the second member such that the first plurality of impellers is interleaved with the second plurality of impellers, the second plurality of impellers being shaped and arranged so as to exert force on the fluid in the same direction as the first impellers when the second member is rotated in a second rotational direction about the longitudinal axis, the second rotational direction being an opposite rotational direction to the first rotational direction; and a motor system mechanically engaged to the first member so as to rotate the first member in the first rotational direction, and mechanically engaged to the second member so as to rotate the second member in the second rotational direction.
