Many articles have been published on corrosion protection systems for increasing the life expectancy of steel reinforcement bars. The performance of these protective systems is documented but not necessarily in a manner for easy understanding.

The Oseberg A Condeep offshore oil platform, commissioned for Norsk Hydro in 1988, is a gravity-based platform built upon hollow slip-formed, reinforced concrete columns. Since start-up, over 1.5 billion barrels of oil have been produced. This is far more than originally estimated and it is now thought that a further 1 billion barrels remain.

Corrosion of reinforcing steel in concrete is of increasing concern among engineers. It significantly affects functionality by inducing cracking and spalling, which compromise structural integrity. Corrosion may be defined as the destruction or deterioration of a metal or alloy substrate by direct chemical or electrochemical attack.

Hempel Paints (Saudi Arabia) has launched a new pipecoating speciality product as part of continuous efforts to provide customers with the latest technology for oil and gas transmission pipeline rehabilitation and maintenance.

The Smart Interrupter (SI) is the latest product launch from pipeline specialist Radiodetection of the UK. Designed for use by corrosion technicians when determining the effectiveness of cathodic protection (CP) on pipelines, this new solid-state interrupter enables the interruption of CP current, an essential part of coating evaluation.

Graham Moorfield and Rob Hossell of Grace Construction Products look at the role that corrosion-inhibiting admixtures play in protecting concrete structures.
