regard to setting out the grid, mooring ves- sels alongside and other issues in regard to the installation. While the CoGP requires that information is provided, this is not always the case. And, when it is, it tends to be general literature rather than technical information. Furthermore, the CoGP places the emphasis on the farmer to obtain information rather than on the manufacturer to supply it.
Mooring installation
Farmers should be required to ensure that moorings are installed by appropriately experienced and/or qualified personnel and inspected prior to use. Companies should have
a documented method to verify that mooring grids are laid in accordance with the instruc- tions provided by manufacturers and the moor- ing specification.
After an installation has been completed, the site should be subjected to a full inspection which should include a visual inspection (by diving or camera) of all elements of the system including anchor positioning. Consideration should be given to whether this inspection should be undertaken by an independent third party with expertise in mooring systems.
Changes in provision
There are occasions where farmers may change the facilities at a given site. This could include adding more or larger cages, us- ing different nets, introducing new or larger wellboats, changes in mooring grids or legs, changes in cage orientation, changes in grid components, changing barges or an increase in boat traffic from other marine users. Previously, there was no requirement to consult engineers before making such changes and hence there have been occasions where installations have been changed without professional advice being sought. It is rec- ommended that any significant changes to an existing site or associated operations be undertaken with the advice of a suitably quali- fied and experienced mooring professional
