DNV GL released a new report providing recommendations on how to perform wellhead fatigue analysis, and describes the main challenges related to wellhead fatigue analysis in the oil and gas industry.
A sufficient margin to failure for drilling operations is a growing challenge for the oil and gas sector, as wellhead fatigue can have significant effects related such as safety, technical and financial.

Examples to perform fatigue analysis in the report include:
- Rig motions including low frequency motion;
- BOP hydrodynamic properties;
- implementation of met ocean conditions;
- how to represent damping in the global riser analysis.
Liv A. Hovem, CEO, DNV GL – Oil & Gas noted that “in the report more than a third (36%) of 813 senior sector players surveyed, expect to increase spending on R&D and innovation in 2018: the highest level recorded in four years. This is encouraging to see.”
Moreover, almost 50% of senior oil and gas professionals said that there is no significant investment in inspection and maintenance of infrastructure and equipment. Despite this fact, a small percentage of the 813 people surveyed answered that they project an increase spending on safety in 2018.
Moreover, according to DNV GL’s report, 49% don’t believe that profitability has impacted safety performance, with 20% believing the opposite. However, more time is needed to determine if profitability impacted safety, DNV GL added.
