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 23 triggered by natural disasters, external
