I was once told a tale about the Methil yard by a Lloyds Inspector. His job was to sample check welds using an ultrasonic tester, this involved being lowered down inside the tubular leg of the production platform on a type of harness with a rudimentary seat . It was a warm summers day and as he worked lower and lower he became more and more aware of the horrible smell. On finishing the job and returning to the top he asked the yard supervisors about this smell, the reply was that the welders were on piecework, and if the call of nature came on them when they were down inside the tube, they didn't waste time getting back to the top and going to the toilet - it all dropped to the bottom of the tube!
