Safe well testing in offshore environments
Post-Macondo (Deepwater Horizon disaster), duty holders and operating companies alike have modernised safety cases for their installations to ensure the highest safety standards are written into operating procedures.
The distance between a ‘Safe Area’ and a Zone II classified area, in accordance with IP15, is three metres from any part of the surface process system. That recommendation is written for fixed production systems employing welded joints, not specifically for temporary well testing systems employing numerous mechanical connections.
During surface well testing, or whilst hydrocarbons are at the surface, steps should be taken to remove sources of ignition in the event of an undesirable gas or liquid release. The volume of gas in a working well test spread can be visualised as a 32ft sphere at atmospheric conditions.
Propagation of a sizeable liquid or gas release in a 25mph wind could be 36ft/s and in this time frame such an event would make it difficult to guard against, especially where engine or boiler intakes do not employ flame traps and/or isolating dampers. To those ends, it is easy to understand why the eminent operating companies and certifying bodies are insisting on using Zone II compressors and Zone II steam generators during surface well testing.
Zone II air compressors and steam generators
Late in 2012, the first pair of Zone II steam generators manufactured were deployed via airfreight to Tanzania. They joined existing 1,600ft²/min Zone II compressors and HeaterSentry® equipment hired by an established British operator involved in gas exploration. Similar projects using Zone II air compressors and steam generators are now ongoing worldwide, as demand continues to soar.
DNV 2.7-2 certified equipment
ScanTech Offshore’s range of equipment now includes a significant fleet of Zone II units built to meet the new DNV 2.7-2 standard, which covers the basic safety requirements from multiple internationally recognised standards, including SOLAS, MODU code and IEC electrical standards.
The DNV 2.7-2 certified air compressor has been designed and developed by ScanTech Offshore to cope with the harsh environments associated with well testing. Using the proven Caterpillar 3406 marine engine and robust 1,600cfm air-ends, the unit is both rugged and reliable. The versatility and safety features of our flagship air compressor have been further enhanced by recently achieving the latest DNV 2.7-2 certification.
Improved safety features include:
- Gas and heat detection
- External refuelling
- External emergency stop
- Safety shutdown system
The DNV 2.7-2 certified steam generator is a 2,500kg/h containerised steam boiler, designed and developed by ScanTech Offshore to cope with the harsh environments associated with well testing. The design criteria and safety functions are built-in to make the boiler suitable for use in offshore Zone II hazardous areas.
Improved safety features include:
- Remote fuel tank
- Fire detection and deluge system
- Safety alarm for low diesel level
- Safety shutdown system
