Participation in TV documentary

 

We took part in a TV documentary about the evolution of offshore platforms. The series is called 'Big, Bigger and Biggest', produced by National Geographic and Channel FIve, and was broadcasted on 18 August 2009. Watch it here if you are in the UK.

This is how Channel Five describes the programme:

Documentary series that examines the technology behind some of the largest feats of engineering in the world. This edition studies six developments that have made the construction of a giant floating oil rig possible. The 45,000-ton Perdido platform lies in the Gulf of Mexico with pipes stretching 3,000 metres into the sea. This feat of off-shore engineering is largely due to six design breakthroughs stretching back to the first oil rig over water in 1891.

 

Vortex shedding

This is an educational video to introduce the mechanism of vortex shedding from a circular cylinder. The cylinder is fixed in a circulating water channel. I used hydrogen bubbles illuminated by a green-light laser sheet. Produced at the Aeronautics Dept., Imperial College London.
