[Reporter Chen Jiayi/Taipei Report] The "Shanghai No. 28" wind farm in the outer sea of ​​Changhua proposed to change the ring difference, hoping to increase the scale of wind turbines, increase the monopile foundation, and cancel the offshore substation. However, the Environmental Protection Committee believes that ecological protection measures such as cetaceans are insufficient. , it should also clarify the underwater noise assessment of the monopile foundation, and it is decided that the case should be re-examined with supplementary information.

The Environmental Protection Agency held today (27th) the second preliminary review meeting of the task force for the "First Environmental Impact Difference Analysis Report on the Environmental Impact Statement of the Strait Offshore Wind Power Project (No. 28 Wind Farm)". The development unit is the Straits Wind Power Company.

The development unit stated that the wind farm on Strait No. 28 is about 14 kilometers offshore, with an area of ​​73.8 square kilometers.

This change plans to add larger-capacity wind turbines to improve power generation efficiency and reduce the number of wind turbines.

In addition, the development unit also proposed that they hope to add a "single-pile foundation" for piling operations.

The development unit pointed out that about 80% of the offshore wind turbines in the world are in the form of single piles. The construction method is relatively mature, and it is more able to withstand seabed changes, and can shorten the offshore construction time.

However, the Taiwan Wilderness Ecology Association questioned that the piling noise of monopile foundations is higher than that of other construction methods such as sleeve foundations, which may adversely affect marine life such as cetaceans.

The Agriculture Department of Changhua County is also concerned that the seabed near Changhua is a thick sedimentary layer, the seabed is geologically unstable, and the supporting force of the single-pile foundation may be insufficient.

In this regard, the Environmental Protection Committee requires the development unit to strengthen the explanation of the suitability of the new single-pile foundation, and compare the underwater noise simulation values ​​of the single-pile foundation and the sleeve foundation under the same piling energy. Assess whether the Changhua seabed geology is suitable for the monopile foundation construction method.

In terms of cetacean protection, the Environmental Protection Committee requires the development unit to strengthen the environmental monitoring plan to understand the possible reasons for the increase in strandings of the first-class protected right porpoise in the Fangyuan area of ​​Changhua; cetacean observers should observe the cable laying process. If cetaceans are found within meters, the speed of the boat should be reduced to less than 3 knots.

This meeting lasted more than 2 hours, and finally the Environmental Protection Committee decided that the case should be re-examined with supplementary information.

The development unit pointed out that the single-pile foundation construction method is relatively mature, can also withstand seabed changes, and can shorten the offshore construction time.
