CATHODIC PROTECTION

Pi designs, supplies, installs, and operate and maintains corrosion monitoring and cathodic protection systems for drainage, ports, tunnels, tanks, coastal structures, critical structures, and prestigious buildings, reducing corrosion maintenance costs and extending target life 50 to 100 years.

Supply and installation We prepare detailed construction drawings and method statements, source and supply materials, train and supervise installation teams, commission, and operate. We typically work as a specialist integrated into the main contractor’s team, which permits maximum installation speed without sacrificing quality, and also reduces costs.

Site investigation and surveys Corrosion arises in numerous forms and can be addressed in a variety of ways. Get an expert opinion of your corrosion concerns, together with recommendations.

Operation and maintenance A CP system without routine maintenance and operation by an experienced cathodic protection specialist is prone to underperformance and even silent failure. Protect your assets and reduce your risks, have your system inspected and operated by a cost-effective external specialist.

 


Consultancy We prepare design documents (drawings, specifications, etc) to ensure your project achieves or exceeds its design life at the lowest cost.

Education We want to share the knowledge. The more you understand how corrosion works, the better decisions you can make about preventing and managing corrosion. Pi offers presentations from a 15-minute quick briefing to a 60 minutes detailed seminar. We also offer hands-on workshops for those who really want to get a firm grasp of how corrosion works and how cathodic protection stops corrosion.

 

Where to use cathodic protection

CP offers high value for steel and steel-reinforced concrete structures in several situations:
 
  • Exposure to seawater, water, sludge: piers, jetties, ports, seawater pumping stations, immersed metallic equipment (stop logs, gates, pumps)
  • Long service life is required: infrastructure, prestigious buildings
  • Low tolerance for shutdown for maintenance: seawater cooling systems, sewage processing
  • Structure is inaccessible for maintenance: closed culverts, seawater intakes and outfalls, reservoir tanks and interconnects

iN-HOUSE EXPERTISE

Pi’s in-house expert, Aleksander Kujbida, has16 years experience installing CP systems in one of the world’s most demanding environments for steel and steel-reinforced concrete, the Middle East. His projects include numerous high profile commercial structures, industrial facilities, and infrastructure.

Nakilat sHIPYARD

A massive new shipyard for Qatar Petroleum. Oil and gas people are very familiar with cathodic protection for handling product (it is regulatory in many countries), so naturally choose CP to protect their new concrete assets.

Remote monitoring and control system to impressed current cathodic protection (ICCP) in piles, berths, and adjacent marine structures.

Louvre Abu Dhabi

 

This spectacular, high-profile project is built on reclaimed land, with numerous interfaces with the adjacent sea. BuroHappold Engineering used cathodic protection to resolve their 100 year durability concern about the extensive H-pile network and the steel-reinforced concrete substructure.

Impressed current cathodic protection (ICCP) tubular anodes for H-piles, ribbon anodes throughout the substructure, remote monitoring and control system, 100 years.

And many more

Ports, jetties, seawater cooling systems, culverts, tanks, intake structures, outfalls, pile foundations, and a variety of other structures. The goals that these owners achieve:

  • Reduce maintenance cost and headaches significantly
  • Extend service life
  • Avoid shutdown for rehab
