Modern Corrosion Mapping of Storage Tank Bottoms--Notable Advancements in Critical Zone Coverage,Inspection Efficiency and Data Integrity

Every day,an NDT(Non-Destructive Testing)report will govern key decisions and inform inspection strategies that could affect the flow of millions of dollars which ultimately affects local environments and potential risk to life.There is a direct correlation between report quality and equipment capability.The more able the equipment is-in terms of efficient data gathering,signal to noise ratio,positioning,and coverage-the more actionable the report is.This results in optimal maintenance and repair strategies providing the report is clear and well presented.Furthermore,when considering tank floor storage inspection it is essential that asset owners have total confidence in inspection findings and the ensuing reports.Tank floor inspection equipment must not only be efficient and highly capable,but data sets should be traceable and integrity maintained throughout.Corrosion mapping of large surface areas such as storage tank bottoms is an inherently arduous and time-consuming process.MFL(magnetic flux leakage)based tank bottom scanners present a well-established and highly rated method for inspection.There are many benefits of using modern MFL technology to generate actionable reports.Chief among these includes efficiency of coverage while gaining valuable information regarding defect location,severity,surface origin and the extent of coverage.More recent advancements in modern MFL tank bottom scanners afford the ability to scan and record data sets at areas of the tank bottom which were previously classed as dead zones or areas not scanned due to physical restraints.An example of this includes scanning the CZ(critical zone)which is the area close to the annular to shell junction weld.Inclusion of these additional dead zones increases overall inspection coverage,quality and traceability.Inspection of the CZ areas allows engineers to quickly determine the integrity of arguably the most important area of the tank bottom.Herein we discuss notable developments in CZ coverage,inspection efficiency and data integrity that combines to deliver an actionable report.The asset owner can interrogate this report to develop pertinent and accurate maintenance and repair strategies.

Transurethral Resection of Bladder Tumour: Safe Implementation of Bipolar Technique

Background: Traditionally, monopolar transurethral resection was the standard surgery for bladder tumors. After developing the bipolar technique, it was noticed that patients’ morbidity was reduced. We aim to compare bipolar and monopolar transurethral resection of bladder tumors in terms of efficacy, safety, and oncological outcomes. Patients and Methods: Clinical records of sixty patients with newly diagnosed bladder cancer who underwent either monopolar or bipolar transurethral resection between March 2019 and April 2021 were prospectively reviewed. Results: Thirty patients were included in each group. The mean age in monopolar and bipolar arms was 59.9 and 57.5 years, respectively. The obturator reflex occurred in 13.33% and 36.66% of the bipolar and monopolar arms, respectively (p = 0.032). Bladder perforation was reported in 2 cases in the monopolar arm. The resection time was significantly longer for the monopolar arm (25.45 Vs 22.85 minutes). Also, the monopolar arm reported longer mean irrigation (23.34 Vs 20.11, p = 0.039), with 1 TUR syndrome reported in the monopolar arm. The mean hemoglobin drop was more in the monopolar arm (0.9 Vs 0.5 gm/dl, p = 0.041). No statistical significance was reported regarding the histopathology results, and one patient in the monopolar group did not have muscle in his specimen. There was no statistically significant difference in recurrence and prognosis between both groups. Conclusions: The bipolar technique has demonstrated its reliability and efficiency as a surgical procedure, providing various advantages while minimizing the risk of complications.

Impact of a simulation-based induction programme in gastroscopy on trainee outcomes and learning curves

BACKGROUND Pre-clinical simulation-based training(SBT)in endoscopy has been shown to augment trainee performance in the short-term,but longer-term data are lacking.AIM To assess the impact of a two-day gastroscopy induction course combining theory and SBT(Structured PRogramme of INduction and Training–SPRINT)on trainee outcomes over a 16-mo period.METHODS This prospective case-control study compared outcomes between novice SPRINT attendees and controls matched from a United Kingdom training database.Study outcomes comprised:(1)Unassisted D2 intubation rates;(2)Procedural discomfort scores;(3)Sedation practice;(4)Time to 200 procedures;and(5)Time to certification.RESULTS Total 15 cases and 24 controls were included,with mean procedure counts of 10 and 3(P=0.739)pre-SPRINT.Post-SPRINT,no significant differences between the groups were detected in long-term D2 intubation rates(P=0.332)or discomfort scores(P=0.090).However,the cases had a significantly higher rate of unsedated procedures than controls post-SPRINT(58%vs 44%,P=0.018),which was maintained over the subsequent 200 procedures.Cases tended to perform procedures at a greater frequency than controls in the post-SPRINT period(median:16.2 vs 13.8 per mo,P=0.051),resulting in a significantly greater proportion of cases achieving gastroscopy certification by the end of follow up(75% vs 36%,P=0.017).CONCLUSION In this pilot study,attendees of the SPRINT cohort tended to perform more procedures and achieved gastroscopy certification earlier than controls.These data support the role for wider evaluation of pre-clinical induction involving SBT.
