Key Info
  • Inventive solution to moving an oil rig
  • Duration: 03:21
  • When something as large as an oil rig needs to be moved it requires a creative solution to the problem. This comes in the form of the Blue Marlin, a transport ship that literally sinks itself in order to pick up its 42,000 tonne cargo. The process takes twelve hours to complete, after which the vessel is almost completely submerged. Once underwater the ship can then scoop the rig out of the sea. In a simple yet brilliantly effective solution, sea water is pumped into the ship in order to allow it to sink. It is them pumped out again when the vessel is ready to return to the surface.First broadcast on 'Supersized Earth' on BBC1 in November 2012.

Ideas for use in class
  • This can be used to show how inventive engineering solutions can be put into place when needing to move large scale objects. It can be used to highlight how engineers sometimes need to think outside of the box when faced with a particular problem to solve. It also shows how the simplest solutions to engineering problems are often the most effective.
