Technical Service


    Cathodic Protection Computing and Research Center, SRI is a professional organization providing technical services in cathodic protection and AC/DC interference numerical simulation and computing prediction. The center is focused on CP and interference researches, aiming at solving corrosion problems in industries related to pipeline, offshore structure, electricity transportation systems, railways, city metro systems, etc. The services include CP diagnosis, CP effect assessment, optimized design for CP systems, life span prediction for sacrifice anodes, AC/DC interference prediction, interference risk identification and assessment, mitigation project design and optimization, etc. The center owns world-advanced simulation software and laboratory facilities. The technical team is well equipped with knowledge and experience in computing simulation. The team consists of 2 professors, 3 associate professors, 4 doctors and a dozen of masters, among whom many are NACE CP certificate holders. 

Core Technology
  • Cathodic Protection Numerical Simulation Technology and Station Area Cathodic Protectoin
  • CP Effect and Service Life Assessment for Offshore Facilities
      Using the method of CP numerical simulation, this technology can comprehensively assess the effectivity, optimize the design and extend the service life for CP systems on offshore facilities, including offshore platforms and subsea pipelines. The cost can be reduced and efficiency increased. Plans for future tests and updates can also be provided.
  • AC/DC Interference Prediction and Mitigation Design
      By using advanced numerical simulation software, maximum and average interference can be predicted and assessed for newly-built pipelines, electricity facilities and finished projects. Accordingly, mitigation and optimizing designs can be conducted, and protection effect can be predicted. The service life of the mitigation measures can also be assessed based on the results of simulation and relevant researches.
