Onshore pipelines otherwise known as land pipelines refer generally to fully buried transport pipelines in the earth. These pipelines are generally coated with organic/polymeric materials for primary corrosion protection. Their cathodic corrosion protection is usually from installed impressed current systems particularly for high resistive soil environments. During the design and construction of such pipeline systems challenges from pipeline routing make it inevitable that a pipeline will cross a fjord or a lake. The cathodic corrosion protection design solution becomes immediately affected where two generally distinct electrolyte environments (soil and water) are involved. This paper attempts to address some of the most common design challenges for a best cathodic corrosion protection system with the use of either an impressed current system for both electrolyte environments installed on land or a combination with a galvanic anode system in water. The use of temporary cathodic corrosion protection systems during construction as a monitoring tool to ensure a good coating quality leading to optimized current density requirements for the pipeline system during the operational life will also be discussed.
