Join us in Aberdeen for an evening meeting featuring presentations on:

Discovery and remedial of HISC failures in the North Sea region

Filippo Mazzoni, Pipeline Operations Engineer, ETAP, North Sea Region

The North Sea region has a history of failures associated with Hydrogen-Induced Stress Cracking (HISC). This presentation will bring to light two recent case studies of failures during operations.  It will cover the journey from discovery through safe remediation to being put back into production service. 

Filippo is a chartered Civil Engineer and is part of bp’s North Sea team responsible for pipeline operations at the ETAP platform.  Outside of work Filippo is married and has two young girls. In his spare time he tries to do a good job as a football referee, but according to spectators that is often not the case. 

Hydrogen Embrittlement with an emphasis on HISC (Hydrogen-Induced Stress Cracking) 

Stephanie Okoye, Vysus

Hydrogen-Induced Stress Cracking (HISC) is a form of Hydrogen Embrittlement (HE) that affects Corrosion Resistant Alloys (CRA) when exposed to Cathodic Protection (CP) under stress or load.  Hydrogen generated on the steel surface due to CP penetrates the material, reducing its ductility and toughness. This increases the risk of embrittlement, particularly in offshore structures, where it can lead to sudden failure.   The presentation will address relevant specifications, standards, and recommended practices, along with potential engineering solutions to mitigate these risks. 

Stephanie is a Chartered Senior Corrosion Engineer with over 15 years of experience in the oil and gas industry, specialising in corrosion and integrity management of North Sea assets and processing plants. She works with Vysus Group and holds AMPP Senior Corrosion Technologist certification. Stephanie also serves as an executive member of ICorr.
