The CP engineering team at CPCL frequently work on a variety of metallic structures, which are either buried or submerged.

CP can be applied to all metallic structures that are buried in soil, sand or concrete; and those submerged in seawater, potable water or other aqueous phases found in oil production and storage.

Our main customers are in the following industries: oil and gas; energy production (e.g. gas, coal, solar, wind); storage (such as firewater tanks); marine ports and harbours; bridge operators and so on. The typical types of structures protected by CPCL can be found below.

Pipelines

Typically modern pipelines are well coated and CP requirements can be either GACP (Galvanic Anode Cathodic Protection) or ICCP (Impressed Current Cathodic Protection); with ICCP being used in longer life, or larger systems and GACP to protect shorter life or smaller systems.

In-plant piping

Either GACP or ICCP can be utilised. Structure isolation is a key question here and CPCL’s preference is for local groundbeds with canistered or linear anode ICCP systems.

Above ground storage tanks

ICCP is recommended when ring-beam type constructions are to be utilised. Oily and Bitumen impregnated sands must be avoided.

Buried tanks and vessels

External and internal CP by either ICCP or GACP.

Well casings

Typically ICCP with a deepwell groundbed is used for this application.

Internal CP to heat exchangers and condensers

ICCP is preferable.

Steel and/or reinforcing steel bar (rebar) in concrete

Predominantly used in the middle east with a growing market in the UK, Europe and other parts of the world.

Harbours and jetties

GACP (with aluminium anodes) is the largest market in this sector, but ICCP can also be applied and is CPCL’s preferred method of protection. ICCP is more suited to longer life applications and can have significant CAPEX cost savings on larger structures. ICCP anodes can be designed to be installed without the use of divers.

Bridge caissons

Submerged steel caissons can be protected with ICCP.

Fixed offshore structures / Floating offshore structures / Ships / Submarine pipelines

These structures are generally protected using GACP and do not fall within CPCL’s core business. We would be happy to recommend other suppliers for this.
