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

Objective: The primary objective of HIPP 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 summary in English

As the industry is pushing for life extension of existing oil & gas fields, they have to cope with an ageing infrastructure. Aging steel structures needs careful considerations with respect to degradation mechanisms as corrosion, fatigue and hydrogen embrittlement. Management of ageing infrastructure is essential to minimize the environmental hazard and avoid large costs due to down time and repair. Elemental hydrogen has dramatic consequences on material properties, especially by reducing the fracture toughness. Degradation by hydrogen initiates through mechanisms occurring locally, and is normally not detectable prior to the final leakage or component fracture. Such incidents are sudden, and sometimes catastrophic failures occur, causing not only huge economic losses, but also irreversible human and environmental impacts. 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.

Project summary in Norwegian

Levetidsforlengelse av olje- og gassfelt i Nordsjøen krever tiltak med hensyn til aldrende infrastruktur. Aldrende stålkonstruksjoner er utsatt for degraderingsmekanismer som korrosjon, utmatting og hydrogensprøhet. For å redusere miljørisiko samt kostnader på grunn av nedetid og reparasjoner trengs derfor tiltak mot degradering. Hydrogen kan ha dramatiske konsekvenser for materialegenskaper, fordi motstanden mot sprekker og brudd reduseres, såkalt hydrogensprøhet. Hydrogensprøhet initieres av mekanismer som forekommer på nanometer-skala, og oppdages ofte ikke før lekkasje eller brudd oppstår. I dette prosjektet vil vi modellere mekanismer som foråsaker hydrogensprøhet og brudd på ulike lengde-skalaer, og verifisere modellene eksperimentelt. På basis av av eksisterende kunnskap og kompetanse innen atomistisk modellering, sprøhetsmekanismer og bruddmekanikk, vil dette prosjektet gi et grunnlag for en helhetlig modell som kan predikere hydrogenbrudd i aldrende offshore og subsea stålkonstruksjoner. Prosjektgruppen består av komplementære grupper ved NTNU Nanomechanical Lab, NTNU IPM, SINTEF Materialer og kjemi og Universitetet i Oslo, med dyktige og erfarne forskere.
