Isothermal subsea sampling system and method

摘要

A system and method for collecting a selected phase of a representative sample from a multiphase fluid flowing through a flowline, preferably located subsea. The system includes a multiphase sampling apparatus attachable to the flowline for sampling the representative sample; a vehicle sampling apparatus (e.g., ROV) locatable proximate the flowline having a power supply and a fluid sample collector for storing at least one selected phase of the representative sample; an interface for connecting the multiphase sampling apparatus and the vehicle sampling apparatus; and a temperature control arrangement disposed between the multiphase sampling apparatus and the vehicle sampling apparatus configured to minimize the temperature difference between the representative sample and the multiphase fluid flowing through the flowline.

1. A system for collecting at least one selected phase of a representative sample from a multiphase fluid flowing through a flowline, the system comprising:
a multiphase sampling apparatus attachable to a flowline for sampling a representative sample of a multiphase fluid flowing through the flowline, wherein the multiphase sampling apparatus comprises a first sampling port and a second sampling port in fluid communication with the multiphase fluid flowing through the flowline for sampling the representative sample; a vehicle sampling apparatus locatable proximate the flowline, the vehicle sampling apparatus comprising a power supply and a fluid sample collector for storing the at least one selected phase of the representative sample; an interface for connecting the multiphase sampling apparatus and the vehicle sampling apparatus; and a heating element configured to minimize the temperature difference between the representative sample and the multiphase fluid flowing through the flowline.
