A man is depicted performing maintenance on a large, heavily rusted ship propeller. He stands within the curved metal structure of the ship's stern, which partially encases the massive propeller blades. The man is wearing practical work attire, including a dark blue jacket with an orange shoulder panel, dark trousers, a dark beanie, safety glasses, and ear protection. He is actively operating a power tool, likely an angle grinder, on one of the propeller blades, generating a visible shower of sparks. The propeller itself shows significant rust and corrosion across its surfaces, though the areas where the man is working appear to have been partially cleaned or ground down to bare metal. The scale of the propeller and surrounding hull suggests a large vessel, such as a cargo ship or tanker, undergoing repair or overhaul in a dry dock or shipyard. The scene is well-lit by natural light, indicating it is daytime. The man appears focused on his task. There is no visible text in the image. The described location context for this activity is Bol'shie Mkhi, Russia.
