A red Hitachi excavator is actively operating in shallow, murky coastal waters, scooping up dark material from the seabed near a rocky shore. The machine's treads are partially submerged, and its bucket moves the material, churning the water. The scene unfolds on a bright, clear day under a blue sky with scattered white clouds. In the background, calm turquoise water stretches towards the horizon, where several rock breakwaters are visible. A metal railing is present in the immediate foreground, partially obscuring the rocky shoreline. The activity is set in a coastal location, specifically Sanremo, Italy.
