ScanTech stacks up in Azerbaijan
ScanTech Offshore is in the process of delivering a specially customised zone II steam boiler and compressor package to an offshore oil drilling rig in the Caspian Sea.
Thanks to its ongoing relationship with major oil companies, ScanTech Offshore was selected to design and build a bespoke package to include three zone II steam boilers and three zone II air compressors for a drilling rig in Azerbaijan. The contract is to support a long-term well testing programme on a large gas field approximately 100km south of Baku.
The package had to be modified to comply with the demanding project specifications and stringent safety standards:
- the tight confines of the rigs laydown area increases re-circulation of the equipment's cooling air so the cooling capacity has been significantly improved to provide reliable operation in extremely high localised temperatures.
- to overcome the tiny footprint an unprecedented concession required the equipment package to be safely stacked conforming to certifying authority standards and 'best oil field practice'
- in the case of accidental liquid or gas escape the package is designed for use in zone II hazardous areas to mitigate potential sources of ignition.
ScanTech's engineering director, Steve Pierce, says;
'The containerised equipment forms part of our rental fleet, which we have been developing over the past five years, but we have adapted items to suit the needs of the client to form an entirely bespoke solution which is thoroughly tested in-house to ensure it confirms to stringent industry standards before being released.'
Steve's team works with relevant offshore certification bodies to ensure all design certifications are in place. Once the equipment is completed and ready for final inspections a certified surveyor performs checks and function tests all equipment safety devices before issuing a final inspection release certificate.
What do compressors do?
- These compressors will be used to provide air to the burner heads to atomise the well fluids measured during the well testing phase
- The compressed air breaks down the well fluid into small droplets to aid the clean burning process
