Welcome to the mid-February edition of the Corrosionpedia News Roundup. We create the News Roundup to keep our readers informed on everything new in the world of corrosion and corrosion prevention. This roundup features stories about several emergencies caused by corrosion such as an ammonia pipeline rupture and a university apartment evacuation. Also highlighted is an exciting new coating method.


Corrosion to Blame for Pipeline Death

An investigation of a pipeline leak that killed a man in Nebraska in 2016 has recently been closed. The failure analysis found that corrosion-induced cracks were to blame for the pipeline rupture. Corrosion fatigue cracking is a common occurrence in structures that are subjected to loading cycles in corrosive environments. Corrosion fatigue cracking occurs when corrosion begins on fatigue crack substrates. The corrosion decreases the time to failure compared with normal fatigue cracking. With an ammonia pipeline, fatigue cracks can corrode quickly and cause rapid failure.

New Nickel Coating Technique

Researchers at Purdue University in West Lafayette, Indiana have developed a new nickel coating technique. The exploration of this new method aims to eliminate problems with conventional nickel coatings such as low strength and susceptibility to corrosion caused by undesirable grain boundary conditions. The team at Purdue was able to achieve this goal by using an approach that promoted the growth of twin grain boundaries and avoided normal grain boundary formation. Twin grain boundaries occur when two adjacent grains are mirror images of themselves across the boundary. This symmetry between grains enhances strength capabilities and impedes corrosion.


Delay Caused by Corrosion Affects Oil and Gas Production

BP, a British oil and gas producer, has announced that it will not be able to complete the third phase of its Egyptian offshore project until the end of 2020. The delay, which occurred in the Raven gas field portion of the phase, was caused in part due to corrosion issues. The project in its entirety is named the West Nile Delta project. When completed it is projected to produce 1.4 billion cubic feet of gas per day. The project started in 2017, and the Raven gas field was supposed to be completed at the end of 2019 until the issues with corrosion arose.

Report Shows Falkland Islands Helicopter Crash Caused by Corrosion

A helicopter in the Falkland Islands crashed in 2018, and until recently the root cause was unknown. However, a report released by the Air Accident Investigation Bureau confirmed that corrosion was the root cause of the crash. After a routine maintenance trip to the United Kingdom, the helicopter was transported back to the Islands. On its first post-maintenance flight, it went nose down immediately after take-off. The report states that corrosion caused a bearing to seize up, which in turn caused the helicopter to crash. The corrosion was thought to have started from inactivity while the helicopter was being transported for maintenance. Fortunately no one was injured during the crash.

University Evacuates Students from Corroded Buildings

Officials at Northern Kentucky University have decided to evacuate students living in some of its on-campus housing units. The apartments were found to have excessive amounts of corrosion on some of their structural components. The findings were revealed in an engineering report performed for the university. According to WCPO, a local news station, the report stated that immediate attention was needed to replace or reinforce the current corroded structures. The university is taking steps to follow the report’s guidance during the evacuation period.

Jakarta Building Collapse Caused by Corrosion

A building that collapsed in Jakarta, the capital city of Indonesia, was caused by corrosion according to the Central Forensic Laboratory, a government lab also located in Jakarta. It is suspected that leaks in the building allowed moisture to come into contact with the steel supports. Over time, this resulted in corrosion that caused the structures to thin out to the point where they could no longer bear the weight of the building and its contents. Eleven people were injured as the building gave way.
