Some Closing Thoughts…

  • It took the right technology, the right

preparation, the right attitude and definitely some luck to successfully conduct any restorations.

  • You can’t prevent natural events like

earthquakes, but what you can do is to prepare well, in advance, and have the people with the right attitude to execute the plan.

  • Co-operations amongst carriers can

improve the chances of overcoming subsea network events, whether these events are triggered by natural disasters, external
