Internal Corrosion Direct Assessment (ICDA) is a pipeline inspection technology where in-line inspection is not practicable. Internal Corrosion Direct Assessment consists of four turn-key processes as follows:

ICDA Processes

• Step 1: Pre-Assessment
• Step 2: Indirect Inspection
• Step 3: Direct Examination
• Step 4: Post Assessment

The most essential key parameter for the success of ICDA process is to understand pipeline flow concepts since ICDA was developed based on pipeline flow concepts. NexCorr has very strong backgrounds regarding multiphase flow and corrosion.

• LP - ICDA (Liquid Petroleum Pipeline Internal Corrosion Direct Assessment, NACE Standard SP-0208)
• DG - ICDA (Dry Gas Internal Corrosion Direct Assessment, NACE Standard SP-0206 )
• WG - ICDA (Wet Gas Internal Corrosion Direct Assessment, NACE Standard SP-0110)
• MP – ICDA (Multiphase Flow Internal Corrosion Direct Assessment, NACE standard SP-0116)

NexCorr also provides a training workshop regarding “Determination of multiphase flow on corrosion in onshore and offshore pipelines”, “ICDA” and “ECDA” upon client request.
