Rens van Helvoirt
I started my career with Shell R&D in 1977. During my employment with Shell R&D, I was involved in the deriving of the Shell standard test procedure for qualification of premium connections (known under the names TEO/3 or EP 92-0147) since 1985.

During this period, I was in charge of a large number of qualification tests on various designs of premium connections. Furthermore, I was responsible for theoretical and experimental research in the fundamentals of metal-to-metal sealing.
