Abstract: A method of processing a fluid produced from a well, the produced fluid being a high pressure fluid, the method comprising: reducing the pressure of the fluid to a reduced pressure such that a gas phase and a liquid phase are formed; separating the gas phase from the liquid phase thus forming a gas product and a liquid product; and storing the liquid product in a storage tank at a pressure such that the liquid product remains in a stable liquid phase during storage, wherein the reduced pressure is greater than atmospheric pressure.

Abstract: Subsea equipment-protection apparatus including a fluid monitoring apparatus for detecting a first fluid, a second fluid and a third fluid. The fluid monitoring apparatus including a first float having a density less than that of the first fluid but greater than that of the second fluid; a second float having a density less than that of the second fluid but greater than that of the third fluid; and a sensor configured to detect the first and second floats so that the position of the floats can be determined. The first float floating when a fluid with density greater than the first float is present and sinking when a fluid with density less than the first float is present. The second float floating when a fluid with a density greater than the second float is present and sinking when a fluid with a density less than the second float is present.
