The oil and petrochemical industry is on high alert for risks to safety and rising maintenance costs, but accidents still happen.
The second day of StocExpo Europe spelled out the real risks and ongoing failures and best ways to prevent them.
The solution is very much to be found in training and refining regulations, Waddah Ghanem, Chief EHSQ Compliance Officer, Emirates National Oil Company, notes.
This issue resonates into the field of tank cleaning with a surprising 80% of accidents caused due to human error. This is mostly down to low level qualifications and foreign contractors finding difficulty assimilating regulations, Orecos Michael Meyer finds.
Tank cleaning has been made more complex today with the focus moving from technical and economic issues to health, safety and the environment.
Orecos Blabo system aims to reduce the loss of Volatile Organic Compounds (VOCs) and eliminates the risks associated with manual tank cleaning, which Meyer believes is still prevalent in most regions of the world.
Players in the sector have teamed-up to examine how best to reduce emissions. Royal Haskoning has collaborated with France-based CarboVac and Aker Cool Sorption on a recent study to look at the effect on reducing power consumption to reduce emission concentrations from 10g/m3 to 150mg/m3. The result was an optimal emission concentration of PSA 2g/m3.
The reduction of emissions concentrations can be also be improved by the pressure drop of a membrane filtration, Royal Haskonings Ben Veldmeijer, explains.
In addition to decreasing emissions, the sector is keen to ensure when maintenance is needed it is available and reliable. For tank terminals operating non-continuous stand-by periods, with alternative line-ups available, and spare parts vendor stocks, the argument is why is maintenance needed?
The need is in reply to tightening regulations, ageing infrastructure, increasing competitiveness, new products such as biofuels and new materials such as coatings. Greater life cycle costs generate the need for more analysis. Teboudins Maurice Houben recommends the use of Failure Mode, Effects, and Criticality Analysis (FMECA) as a proper tool; it has an adequate level of detail and evaluation of risk versus performance targets.
Teboudin recently and successfully worked on Vopak Botlek terminal tank-pit 19 on eight storage tanks at 156,000 m3 containing petrol and ethanol.
Due to FMECAs limits, such as limited examination of external influences, Houben advises the analysis includes a maintenance chapter, asset register and spare
Key speakers on the afternoon of day three of the conference will include Stefano Cagnola from Isoil Impianti, Ulf Johannesson from Rosemount Tank Gauging, Bekaerts Boris Meary and Frank Kouwenberg, and finally David Adams from Honeywell.
