Prior to developing new sites it is vital that a full survey is carried out. This is particularly important as Aquaculture spreads to new regions of the world and current technology is stretched to the limit.
Although for best results, our surveyor should visit the site and carry out a full survey we can supply a detailed questionnaire which can enable the customer to provide the required data and allow us to give a recommendation based on that data and our experience. However, the quality of the report will very much depend on the quality of the information provided. |
Surveys ADCP, Madeira.
|
A Kames specialist surveyor will carry out the following services.
Wind & wave climate assessment
Wind rose demonstrating wind strength and distribution.
|
Most wind statistics will come from terrestrial weather stations such as airports or meteorological centres. Wind speed should be estimated to give a good degree of accuracy and seabed topography and an anchor test to assess sediment type and likely anchor efficiency.
|
Hydrographic survey
Current meter.
|
A current meter is used to measure current velocity, direction and duration
|
Bathymetric survey
Survey to plot underwater contours and sea bed shape.
|
In locations with complex underwater topography it is essential to make a detailed survey to locate any underwater obstructions and understand the differing materials which may be found in the sea bed . This will enable the designed to properly locate the fish farm.
|
Calculating the forces
|
The force acting on the mooring lines is a combination of wind, wave and current. External non environmental forces are also taken into consideration . This might include large ships which have to moor along -side the cages occasionally or feed rafts. Safety margins and redundancy are also built in to the design at this point.

Anchor tests
Anchor tests are used to prove anchor holding power at different locations around the proposed site .
