Info

To assist in cases of emergency, the turbines will be equipped with Þ rst-aid kits, life buoys, duvets, Þ re extinguishers and Þ re alarms. There will also be communication equipment on the turbines for direct communication with onshore rescue stations. There will be equipment making it possible for humans to climb out of the water. Each turbine will be equipped with an overnight room equipped with a bed and foodstuffs. Service personnel will be educated in the special risks that are associated with offshore equipment. Service work onboard the turbines will follow special routines. In connection with the construction phase, security routines for work on the turbines as well as for transport to and from the service station in Trelleborg will be devised. All service personnel and other casual visitors will have to undergo survival training in order to be allowed to board a turbine in the wind farm. The same rules as being used onshore, will be used for high current work on the turbines. In conjunction with affected authorities and rescue organisations, a contingency plan will be devised. The Coast Guard and not the coastal communities of Skåne will be responsible for concerted actions. Rescue exercises will be held during the construction phase. Sweden Offshore will propose the security increasing measures recommended by SSPA and decisions in this matter will be made in consultation with the affected authorities. CONSEQUENSES OF THE WIND FARM 119 12.1.3 Assessment ASSESSMENT CRITERIA Very high impact (high value – high impact) • The structure will cause threshold values for environmental quality in- and outdoors, not to be fulfi lled. • The structure will cause very big noise deterioration. High impact (high value – reasonable impact/reasonable value – high impact) • The structure will cause threshold values for environmental quality in- and outdoors, not to be fulfi lled. • The structure will cause big noise deterioration. Medium impact (medium value – medium impact) • The structure will cause threshold values for environmental quality indoors to be fulfi lled and outdoors not to be fulfi lled. • The structure will cause reasonable noise deterioration. Small impact (reasonable value – no impact/small value – reasonable impact) • The structure will cause all thresholds for environmental quality being fulfi lled and will only cause minor noise deterioration. Minor/no impact (small value – minor impact) • The structure will cause all thresholds for environmental quality being fulfi lled and will only cause marginal noise deterioration. Conclusion No thresholds for environmental quality will be exceeded and no noticeable deterioration of current noise levels will occur. In view of the very low accident risk, it is, in summary, concluded that the wind farm will cause very little negative impact for human health.
120 CONSEQUENSES OF THE WIND FARM 12.2 Hydrography The hydrography in the area is described in Chapter 11.2 12.2.1 Impact Saltwater ß ows from the Kattegatt along the seabed past the area where the wind farm is planned and further into the Baltic Sea via the Arkona and the Bornholm basin. During the inß ow, the incoming water is gradually mixed with water of less density from above. For this reason, the salt level and density of the inß owing water is reduced before it reaches the real Baltic Sea. If the wind turbines are built in the path of the inß owing water, the mixing will increase slightly, which in turn will cause water will slightly less salt content and density to reach its destination. SMHI has made a simple calculation of what the maximum size of the mixing may be, i.e. calculated an upper threshold of the impact that the wind farm may get (Attachment 5.2). The calculation has been made so that a high safety margin has been obtained regarding the volume of mixed water. The result shows that the salt water mixing will increase by much less than 1 % compared to the current average mixing. From this, SMHI concludes that the wind farm will not have a negative impact on the saltwater mixing in the Baltic Sea. On behalf of the group, the company Hydromod has also investigated whether a wind farm on the German side of Kriegers Flak may inß uence the saltwater mixing and they have concluded that the impact will be negligible (Attachment 5.1). Within the area of the wind farm, a marginal lowering of the wave height and wave character is expected. This will not have any environmental impact. Summary The salt water mixing will increase much less than 1 % compared to the current average mixing. 12.2.2 Mitigating measures While planning the wind farm, Sweden Offshore has considered the results that have been forthcoming in the investigations and the turbines will be placed where the least possible impact is caused on the ß ow of water. 12.2.3 Assessment ASSESSMENT CRITERIA Very high impact (high value – high impact) • The structure will cause permanent disturbance/ deterioration of the water quality/salt balance that will destroy the eco system and threaten red listed species. High impact (high value – reasonable impact/reasonable value – high impact) • The structure will cause permanent disturbance/ deterioration of the water quality/salt balance that will destroy the eco system or threaten red listed species. Reasonable impact (reasonable value – reasonable impact) • The structure will cause permanent disturbance/ deterioration of the water quality/salt balance that will have a permanent impact on the eco system or a temporary impact on red listed species. Small impact (reasonable value – small impact/small value – small impact) • The structure will cause occasional disturbance/ deterioration of the water quality and quantity that will cause occasional impact on the eco system. Minor impact (small value – minor impact) • The structure will have no impact on the water quality/salt balance that has an impact on the eco system. Conclusion The impact on the hydrography will be minor/negligible.
