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.
