Abstract

Pipeline is widely used in the offshore industry to transport all the oil and gas product from the offshore platforms to the onshore facilities. Large investment has been made by most oil and gas company in order to make sure offshore pipelines could last for their design life. So far, cathodic protection system and coating protection are the best solution in order to control the corrosion process along the pipeline. Over the years, cathodic protection has doing great in controlling the corrosion process for all offshore pipeline which either been buried or being laid in the deep water. However, the corrosion problems for pipelines near tidal zone area seems to have been overlook by the people in this industry. All these years, pipeline coating has been widely used in order to protect the pipeline in the tidal zone area.
Generally, this research will study and analyze the response of cathodic protection system near tidal zone area. It will focused more on finding out the cathodic protection potential at tidal zone area close to shoreline. A few equations is being used and adapted with cathodic protection design from PETRONAS PMO in order to find out the dissipation of cathodic protection potential at tidal zone area. It seems that sacrificial anode does not function effectively in tidal zone area due to the absence of stable seawater electrolyte. Sacrificial anode needs a stable electrolyte around the metalwork to enable the anode to function effectively.
