Hydrogen-induced degradation of offshore steels in ageing infrastructure – models for prevention and prediction (HIPP)

Project lead: Professor Zhiliang Zhang, Norwegian University of Science and Technology -NTNU, Department of Structural Engineering, Faculty of Engineering Science and Technology, NTNU Nanomechanical Lab, Norway

For more information about the project, see the project webpage

The primary objective of HIPP Project is to develop a model framework which describes and couples environment-assisted hydrogen degradation mechanisms at different length and time scales towards a predictive mechanism-based integrity assessment approach for oil and gas steel infrastructure.

Project Duration: 2014-2018, Funding: The Research Council of Norway, PETROMAKS2 Program

This project attacks the challenge by linking modelling of fundamental mechanisms on different scales. On the basis of existing knowledge and expertise on atomistic simulations, embrittlement mechanisms and fracture mechanics assessment, this project will provide a scientific platform for an integrated model that can assess hydrogen induced failures in offshore steel structures.

The project team consists of three complementary groups (NTNU Nanomechanical Lab, SINTEF Materials and Nanotechnology, and University of Oslo), of skilled and experienced scientists that join their efforts in order to realize a mechanism-based integrity assessment approach.

The Network of Excellence (NoE) in Hydrogen Embrittlement


The Network of Excellence (NoE) in Hydrogen Embrittlement aims to strengthen scientific and technological excellence by developing an integrated and interdisciplinary scientific understanding of hydrogen degradation of engineering materials and their co-evolution with science, materials science, industry and society, and also by addressing the fragmentation of European and Worldwide research in this area.

The Network of Excellence in Hydrogen Embrittlement is structured so that it consists of the following branches:

  1. Hydrogen Embrittlement Group on LinkedIn
  2. Hydrogen Embrittlement  – Understanding and research framework Project  on ResearchGate
  3. Hydrogen Embrittlement Group on Mendeley
  4. Hydrogen Embrittlement and Materials Science Blog on WordPress
  5. Research Topic titled “Hydrogen Embrittlement Mechanisms” (now closed) in collaboration with Frontiers in Materials Journal within Corrosion Research section
  6. Damage and Fracture Mechanism Group on LinkedIn
