Application of the new Norwegian standard for certification of fishfarms.

Chairman N.N. Fish Farmers Ass.

3. New technical standards - why? Challenge
Damage and wreckage in floating fish farms in heavy weather
Escaping fish, an issue of protection of wild stocks
Security of the people
Lost money for the farmer
Goal: reduce escaping of fish and improved security

4. Solutions
Floating farms must be proven to withstand forces under extreme conditions at their specific site.
All farms in Norway must conform to a minimum standard.
Norwegian standard 9415 (Nytek) – every farm must have a certificate at each site .
Standard is developed by the authorities AND the fish farmers.
Can neither cope with sabotage, collisions with ships nor with tsunamis.
The German answer would be - Verboten !
By 2012 all equipment must be certified by producers for the site where they are moored.
In the meantime old farms get a certificate called dugelighetsbevis which certifies that equipment is appropiate

5. The site – step I Forces induced by
wind
tides
bathymetry and topography
give site specific currents and waves
These work on the construction.
Measure & calculate site specific forces!
currents (28 days pluss risk margins)
waves are modelled from winddata & topogr.
= input data for further computations
= classification of site.

7. Floating construction – step II
Cope with the forces?
design of mooring system & positioning
strength of ropes, shackles, chains, etc.
PE-rings (steel or wood), nets
Simulate forces in dynamic modell called ConMotion®.
Results in tension map in each point of the construction
Controle if the design of the farm and the chosen equipent complies with the expected extreme forces.

8. Audit documentation – step III
Collecting of specifications, descriptions & manuals for
equipment,
procedures,
maintainance.
Review the documents
complete ?
correct ?
specs. comply to forces?

9. Inspection and deviations – step IV
Visiting the farm and inspect equipment
is it what it claims in the papers?
is it in good shape?
is assemblage correct?
Report deviations.
Follow up correcting of deviations.
Issue certificate.

10. Achievments
improved the technical standards and quality of design and equipment
minimum standard in ALL farms
starts a process in the mind of more people
reducing escapees
