Cathodic Protection Systems Engineering

Petunia Engineering Team has been provided successful cathodic protection solutions to the Oil, Gas, Petrochemical, Water and Power Industries for over 30 years. Structures that are commonly protected by CP are the exterior surfaces of:
  • Pipelines – oil, gas, product, water etc.
  • In plants piping
  • Above ground Storage tank bases (external plates of aboveground storage tanks)
  • Underground Storage Tanks
  • Well Casing
  • Compressor stations
  • Ships’ hulls
  • Marine Structures, Jetties, harbour, etc.
  • Concrete structures –bridges, pipelines, marine structures, etc.
  • Cathodic protection is also used to protect the internal surfaces of:
  • Large diameter pipelines
  • Storage tanks (oil and water)
  • Ship’s tanks (product and ballast)
  • Water-circulating systems.
  • Measuring the resistance of MMO ribbon anode
  • connection to the conductor bar

Our NACE-qualified engineers can provide Cathodic Protection design based on client specifications and recognized international standards.

Petunia engineers are experienced with the design and performance of all CP applications and their particular functions in variant situations. For new or supplemental systems (sacrificial anodes or impressed current ground beds), consideration is given to point or distributed surface configurations, deep anodes, or linear anodes to achieve the client’s corrosion control objectives, and to meet designated CP criteria as efficiently as possible.

Our projects include pipelines, storage tanks, tank farms, docks, offshore platforms, sheet-pile walls/bulkheads, military facilities, boats/vessels, steel/concrete-based structures, and lastly but not limited to, water and waste treatment plants.


The following are just some examples of our engineering services:

  • Current Drain
  • Ground bed location
  • AC corrosion monitoring and mitigation
  • Detailed engineering
  • Technical document preparation
  • supervision of installation works
  • Pre-commissioning and Commissioning of Cathodic protection system
