To safeguard the technical integrity of subsea pipelines and structures a combination of cathodic protection and/ or coatings are used to protect external steel surfaces from corrosion.

Regular inspection of the cathodic protection systems provides information as to its condition and allows identification of any areas that may be susceptible to external corrosion due to inadequate cathodic protection.

Cathodic protection systems that are not performing satisfactorily can lead to under protection of the steel surface, resulting in corrosion on the pipeline & ancillary surfaces. If remedial action is not taken, continuing degradation processes can lead to thinning of the pipe wall resulting in failure & loss of containment. Depending on the degree of failure & the pipe contents, serious consequences can ensue in terms of injury, loss of life, economic losses & environmental impact.

In order to ensure that offshore CP systems are operating satisfactorily, there are a number of different methodologies that can be employed to provide information as to the condition of a facilities cathodic protection system and thus provide a quantifiable indication of continuing integrity assurance.

After a brief introduction on the basics of cathodic protection in marine environments, the following methodologies will be discussed in reference to pipeline & structural marine CP surveys.

  • Proximity half cell 
  • Single point contact systems (Spot CP ) 
  • Single point contact with continuous CP ( Cell to Cell Method) 
  • Single point contact with Continuous CP & Field Gradient 
  • Trailing Wire CP Survey


Craig graduated as a materials & Corrosion engineer from Robert Gordon University, Aberdeen, Scotland more years ago than he cares to remember and has worked in the offshore oil & gas industry for over 35 years. He has worked in many of the major offshore oil & gas producing areas around the world, including the North Sea, Gulf of Mexico the Middle & Far East and Australia. He was Technical Director for a specialist corrosion monitoring company in the UK and was involved in several innovative developments in corrosion monitoring technologies. He is a professional Member of the Institute of Corrosion in the UK.

Craig is currently Managing Director & co-founder of Inspection Survey & Integrity Services; a company incorporated in Malaysia in 2003 that specialises in offshore underwater inspection activities primarily concentrating on cathodic protection survey of offshore oil & gas installations and pipelines, however other areas of business interest include drone inspection and 3D scanning technologies. The systems and services used for cathodic protection inspection have been developed “in-house” and as such the company has developed a reputation as one of the leading providers of this specialist service worldwide, with offices in Kuala Lumpur, Singapore & Aberdeen. Regular clients include most of the major international oil & gas producing companies.

He has now lived in Malaysia with his wife & family for the last 16 years in what was supposed to be a two year secondment…. The lure of Nasi Lemak & Fish head curry was just too much to resist.
