A method for the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead, the multi-phase production fluid comprising a water phase, an oil phase and a gas phase. The method includes introducing the multi-phase production fluid into a pipeline, the pipeline extending from proximate the wellhead to a point remote from the wellhead; imparting rotational motion to the multi-phase production fluid; wherein the rotational motion of the multi-phase production fluid separates the water phase from the oil phase and the gas phase and reduces the pressure drop along the pipeline. A system for the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead and a method for reducing hydrate formation during the subsea transport of a multi-phase production fluid from a wellhead to a point remote from the wellhead are also provided.
