The failure of a 5″ casing hanger at an oil well led to costly workover operations and lost production. The brittle failure was due to the instantaneous propagation of a circumferential fracture, initiated at a geometrical stress raiser. Combined o

The analysis of multiple cracks in a heat exchanger tubeplate at a petrochemical plant led to experimental replication of in-service damage. High lifting stresses created a first leak that was repaired. Extended branched intergranular cracking develo

In the last thirty years lightning properties have been measured with a high degree of detail. Yet, the mechanisms by which lightning causes failure of buried structures are still not fully identified. This work addresses results from experimental st

This article analyzes a 3.5% Ni steel cryogenic cylindrical vessel, after the detection by nondestructive inspection of cracks in a circumferential weld. Possible in-service damage mechanisms are discussed, in particular, vibration, low cycle thermal

The failure of a 24“natural gas pipeline buried in the 1960s led to a blowout followed by fire. The damage caused the breakage and expulsion of 20 meters of tube; flames reached 30 meters high. The break occurred at the edge of a high transit route

A drill bit with polycrystalline diamond (PDC) inserts lost one of its three blades when operating in an oil well, leading to a costly failure. Operating conditions and associated stresses were analyzed, bit core material in the failure and adjacent

Drilling with casing (DwC) is an innovative method particularly widespread in deep shale plays, that reduces the time and cost of drilling stages. However, casings are not designed for this purpose, and still the pipes and connections are required to

Catastrophic failure of cranes is a potentially very dangerous event and has often fatal consequences. The failures of two cranes are discussed in this study. Both cranes have different designs, but common root causes have been identified, related to

Buried pipelines interact with the soil that is founding them. Pipelines are subjected to additional loads transmitted by the movement of the ground. Geotechnical remedial works to control soil (fast) slides or (slow) creeping are often costly, so th
