“Our primary aim is to help engineers to develop the necessary knowledge, skills and confidence to be able to dramatically reduce the risk of pipework vibration related incidents both onshore and offshore”
Many serious pipe vibration issues can be easily detected using simple vibration screening techniques. If undetected, excessive vibration can result in fatigue cracks at welds resulting in pipe fracture and leakage.
In industries dealing with hazardous liquids or gases, such fractures could lead to serious incidents involving major injury, fire, explosion or pollution.
Skills necessary to perform vital risk assessment surveys on business and safety critical pipework and associated small bore connections (SBCs) can be learnt by investing in a few days training.
All VibTech training is live and instructor led. No pre-recorded videos
Bespoke Training Courses (for organisations)
The majority of VibTech Online Training courses are bespoke ‘corporate courses’ for individual companies and are attended only by engineers from that company.
This means that the company can tailor the course to meet their specific requirements, focussing on key corporate objectives.
This might include a greater emphasis on such areas as:
- Theoretical focus – Stronger emphasis on office based Quantitative Assessments to calculate Likelihood of Failure (LOF)
- Practical focus – Stronger emphasis on on-site measurement based methods, including visual inspection and vibration and strain monitoring
- Solutions focus – Stronger emphasis on diagnostics and implementation of Corrective Actions and permanent Solutions
To provide great flexibility to meet all requirements, VibTech has developed a suite of up to 10 training sessions covering all aspects of pipework vibration, including the causes of vibration-induced fatigue damage, assessment methods, and problem solving.
The 10 sessions are made up from over 36 individual training Modules covering all aspects of the subject of Pipework Vibration compliance and the avoidance of vibration induced fatigue failures.
Companies wishing to arrange training for their staff can select all required sessions from the full list of online training sessions.
