Vortex Dredge - Mini Gas Sampling Tool - Version 2.2

1.INTRODUCTION
The vortex High pressure Gas Sampling tool is designed to capture gas and liquid samples in a
subsea environment and recover said samples to the surface in a high pressure state of no more
than 1800psi (124bar) by means of an electro mechanical operated syringe to ingest sample then
purge sample into a sample bottle after recovery to surface.
This tool is designed to be deployed from the surface with the bottle bled of air and a vacuum
entrained in the system. Sample filling relies on the entrained vacuum and ambient water
pressure filling the bottle when the main isolation valve is operated.

2. SAFETY
2.1 Overview
All local HSE procedures must be followed. Use of PPE should follow guidelines outlined with
handling of potential sample. For example hazardous gas samples should have PPE appropriate
to mitigate dangers associated with that gas. Safety glasses should be considered minimum
requirement irrespective of potential sample. Your safety is your responsibility. Think and plan
ahead accordingly.
2.2 Risk Assessment
Consult with local HSE and installation operators to identify best practice steps needed for safe
operations. Identify if the task been done and implement lessons learned. JHA, permitting and
toolbox talks should preclude all operations.
2.4 Mechanical
Ensure all fittings and fasteners are secure. Check general condition of tool against images in
manual for anything which may indicate potential operational issues.
•Remember, your safety is your responsibility. Think and plan ahead
accordingly. If in doubt, please ask.

3. TECHNICAL SPECIFICATIONS
3.1 Description
To “Suck” the sample into the syringe the operator will function the main isolation valve to open
the circuit to ambient pressure and ‘draw’ the sample into the bottle.
To entrap the sample in the sample bottle the operator will function the main isolation valve
closed to seal the circuit and entrap the sample in the sample bottle.
