The barge working positions, provides sufficient space in the navigational channel for smaller commercial, fishing and leisure vessels to safely navigate past. Should a large commercial vessel movement be anticipated close to the works area, then the barge will be moved as required. Figure 1 shows the area of works, figure 2 shows planned positions of the barges during works. This is the first phase of the works. A new notice will be issued detailing works and barge positions when the next phase of works is planned.
