CASE STUDY - 10 HURRICANE
SITUATION: HURRICANE INCIDENT: STORM FRACTURED THE WALKWAY
RESPONSE: INCREASE SPECIFICATION The situation:
The night of 11th January 2005 will re- main long in the memory of those living and working on Scotland’s west coast and islands. The hurricane brought with it the highest ever recorded wind speeds in Scotland.
The hurricane severely tested all that was in its way. As well as the immense wind speeds, fi sh farmers spoke of the storm surge, which greatly increased the height of the tide and speed of the cur- rent.
The incident: A number of fi sh farm sites suffered greatly in the hurricane. This example is of steel pens on the west coast of Scotland. Putting together the evidence from the remains of the site, the farmers think that one cross member of the steel walkway fractured in the extreme condi- tions, leading the walkway to submerge. This dragged the top of the net below the surface causing many fi sh to escape. The severity of the conditions and the longevity of the storm not only gave rise to considerable damage but also made it harder to access the site to try and rec- tify the situation.
THE RESPONSE
Despite the extreme and unprecedented weather conditions, the company reviewed its equipment in the light of the in- cident. They decided to increase the specifi cation and change their equip- ment to reduce the likelihood of similar instances should the unthinkable happen again.
Such reviews were carried out by other affected farmers. The industry is of the opinion that the very considerable in- crease in specifi cation makes such sites less vulnerable to any future extreme weather event.
