Measurements

Cathodic protection is an important step towards high-quality metal products, but it only makes sense if its operation is regularly monitored. That is why Merrem & la Porte has its own team of experts who can perform all necessary inspections, certifications, and tests.

Measurement service of the cathodic protection department

The cathodic protection department of Merrem & la Porte has its own measurement service. Using advanced equipment, our skilled engineers conduct potential measurements. In addition, comprehensive investigations such as Close Interval Potential Surveys (CIPS), and Direct Current Voltage Gradient surveys (DCVG) are also possible.

Cathodic protection measurements:

• Potential surveys
• Baseline measurements
• Research survey
• Coating inspections (ACVG, DCVG, CIP, and ECDA survey)
• Line current tests
• Soil resitivity measurements
• Wall thickness measurements

Proceedings

The cathodic protection department of Merrem & la Porte designs and supplies complete CP systems with sacrificial anodes for underground storage tanks and small underground steel pipelines (such as inverted siphons). Additionally, we design and deliver cathodic protection for large pipeline networks of steel gas pipelines or transportation pipelines in the chemical industry.

Sacrificial method for cathodic protection

At Merrem & la Porte, you can rely on sacrificial cathodic protection methods. Furthermore, Merrem & la Porte specializes in supplying and installing cathodic protection through impressed current. One of the largest projects we have had the opportunity to handle in this field is the Storm Surge Barrier in Nieuwe Waterweg. Our company provided a well-functioning CP system to the full satisfaction of Rijkswaterstaat.
