Several networks of pipelines in Nigeria oil and gas industry have failed catastrophically in the last two decades because most oil pipelines operate in a corrosive environment and transport corrosive fluids. This research experimentally investigates the corrosion of a carbon steel pipeline immersed in a typical Niger Delta Offshore Environment. The experiment was carried out using the gravimetric (weight loss) method. The carbon steel coupon was immersed in a sample of water collected from the Niger Delta sea and in seawater polluted by 0.5mol/dm3, 1.0mol/dm3, 1.5mol/dm3 and 2.0mol/dm3 tetraoxosulphate (VI) acid respectively. The coupons were retrieved and examined at 4-hour interval. It was discovered that in an unpolluted state, the seawater was not corrosive. However, when polluted by 0.5mol/dm3, 1.0mol/dm3, 1.5mol/dm3 and 2.0mol/dm3 tetraoxosulphate (VI) acid, corrosion occurred. The highest rate of corrosion was observed in the coupon dipped into the seawater sample polluted by 2.0mol/dm3 of tetraoxosulphate (vi) acid and the lowest corrosion rate observed in the least polluted seawater 0.5mol/dm3. Corrosion rate increased with increasing pollutants; therefore, it is imperative for oil operators to carefully dispose of their waste to prevent rapid corrosion of subsea pipelines and other offshore facilities.
