Corrosion Management
The corrosion management expertise offered by INTECSEA is listed below:
- Cause and effects of corrosion
- Causes of failure to pipelines, risers and subsea equipment
- Forms of corrosion - galvanic, crevice, pitting, preferential weldment corrosion, corrosion fatigue, inter/intragranular, SCC, SSC and HIC, SOHIC, MIC
- Internal and external corrosion mechanisms on pipelines, subsea structures/components, topsides components, piping
- Corrosion theory, anodic/cathodic reactions, polarization diagrams, Evans diagram, principles of cathodic protection, over potentials, galvanic series/couples
- Cathodic protection systems for subsea components, offshore pipelines, offshore structures and onshore pipelines and tanks and terminals
- Chemical inhibition recommendations
- Ensuring that compatible coatings are used
- Specifying and checking coatings before, during and after application
- Coatings selections for pipelines, risers and subsea structures and topsides, e.g. coal tar, FBE, polyolefinics, 3 layer systems, PU, insulation
- Coating testing (laboratory and field) – cathodic disbondment, impact, high temperature, high pressure, collapse, sour service
- Selecting, specifying and checking cathodic protection monitoring systems and site surveys
- Field joint coating materials selection, design and application methodologies
- Corrosion monitoring by coupons, ER, LPR probes
- Hydrate prevention (methanol)
- Dehydration systems (MEG/TEG)
- Dew point control
