East Africa’s Leakage Incidents Points to Detection Needs
Barely one year after the commissioning of East and Central Africa’s only refined oil transportation pipeline in Kenya, leakages have been reported, raising concerns about the ability of existing government agencies to monitor the safety of oil infrastructure at a time when similar projects have been unveiled across the region.
Slam-Shut Technology for Ultra-Low-Pressure Protection
Natural gas is an abundant fuel used for both industrial and residential energy and is one of the few energy sources delivered directly into our homes. Because it’s also a flammable, potentially explosive fluid, natural gas utilities and distribution companies are required to prioritize safety and devote focus to their protection systems to prevent over-pressurization accidents, even for systems operating at extremely low-pressure levels (< 1 psi).

Looking to Lessen Fluctuating Flow Problems in Measurement
Good measurement practices suggest flow measurements should occur without instabilities or pulsations in the flow. Even minor inaccuracies in the measurement of high value products can lead to significant financial exposure over extended periods of time.
Using Computational Fluid Dynamics When Equipment Fails
The importance of accurate measurement cannot be under-estimated. In 2012, the oil price was above $100 per barrel, but only a year later, as oil prices began to decline, the average price of a barrel of crude oil was $91, dropping to $42 by 2015.
