Abstract
The present invention provides a drain apparatus for use in a subsea pipeline to remove liquid from a multiphase flow in the subsea pipeline. The drain apparatus comprises a first channel for carrying a multiphase flow comprising liquid and gas phases; and liquid extraction means for extracting the liquid phase from the multiphase flow in the first channel. The internal diameter of the first channel is substantially the same as an internal diameter of a subsea pipe arranged to carry the multiphase flow in the subsea pipeline, such that a pig travelling along the subsea pipe can pass through the first channel. The present invention also provides a subsea pipeline comprising a subsea pipe for transporting a multiphase flow subsea; and at least one drain. The at least one drain is disposed partway along a gradient in the subsea pipe to reduce liquid holdup.
