A METHOD OF SUBSEA TESTING USING A REMOTELY OPERATED VEHICLE

摘要

A method of subsea testing using a remotely operated vehicle (ROV) is provided. The ROV has a spectroscopic sensor, preferably an x-ray fluorescence or neutron activation analysis sensor. The method includes identifying seafloor material to analyse, directing the ROV to the identified seafloor material, and analysing the seafloor material with the spectroscopic sensor. The method allows real time, or at least near real time, analysis of seafloor materials of interest without the need to obtain samples for analysis at the surface.
