Abstract: There is described subsea apparatus and a method for processing fluid from a well. In an embodiment, a pipeline (6) may be arranged to carry the multiphase fluid containing liquid and gas from the well. An outlet (10) extending through a wall of the pipeline may let gas out of the pipeline from said region and through the outlet to separate said gas and liquid. A compressor may be connected to the outlet to compress the separated gas. The separated liquid and the compressed gas may be combined. Separated liquid may be conveyed along a sloping portion of the pipe to a low point in the seabed terrain, and may be conveyed to a pump for boosting the flow of liquid. The pump may be located in an excavated hole or glory hole below the seabed.
