The Tengiz oilfield in Kazakhstan is one of the deepest developed super giant oil fields in the world, with further expansion projects in the pipeline.
The aim of the Future Growth Project is to increase the daily production of crude oil to 850,000 barrels per day, a planned growth of 240%. Running simultaneously, the objective of the Well Head Pressure Management Project is to keep the existing plants full by lowering the flowing pressure at the wellhead and then boosting the pressure to the inlet requirements of the six existing processing trains. Plans include the construction of a crude stabilization unit, an oil gathering system, power generation facilities and two sour gas compressors.
Tengiz prides itself on not only being one of the largest oilfields in the world, but also one of the safest, meaning the provision of emergency safety showers to protect the workforce is of utmost importance.
As with many sites of this nature, challenges such as lack of a constant water supply, extremes in temperature from -40°C to +45°C and remote and hazardous environments must be considered when sourcing emergency safety showers.
Due to the extremes in the Kazakhstan climate the provision of tepid water is essential. If the water is too hot a casualty is at risk of scalding, too cold and they are likely to leave the shower before the ANSI recommended 15 minutes rinse time is complete.
Additionally, any outdoor safety showers must offer protection from the elements to ensure a safe and comfortable environment for a casualty until help arrives.
Hughes provided a fully customised solution to the end user. Floor mounted emergency safety showers with eye/ face wash, featuring stainless steel pipework were specified for indoor use where a mains water supply was available to feed the safety showers. The same model was also specially engineered for the more remote indoor facilities with the ability to feed it via a gravity fed water tank, the most efficient method due to the unreliable water supply.
