Abstract: A system for surge protection of a riser adapted to transport gas from a hydrocarbon production well or for surge protection in a well, the system comprising: a flexible tubing, wherein a portion of the flexible tubing extends into the riser or into the well and wherein the tubing terminates inside the riser or inside the well; a pressure control system arranged to create a pressure differential within the flexible tubing such that liquid is drawn from the riser or the well into the flexible tubing if liquid is present in the riser or the well; wherein the length of said portion of the flexible tubing is variable depending on the amount of liquid drawn into the flexible tubing.

Abstract: Subsea apparatus (10) for processing a well stream (2) and a method of processing a well stream subsea is described. In an embodiment, liquid (5) and gas (3) contained in the well stream (2) is separated. The separated gas (3) is cooled and the cooled gas (32) is combined with the separated liquid (5) to form a wet gas (52) for a compressor (90). An active cooling arrangement (30) may be used in one example to enhance the cooling effect provided by the cooler (30). Advantageously, the apparatus (10) can be arranged compactly, and may be provided on a subsea retrievable module.
