offshore oil rig 3d model

Ultra-detailed 3D model of an offshore oil rig platform, industrial realistic style, no ships or boats nearby. The structure is a massive semi-submersible oil platform standing on multiple ضخ cylindrical support columns rising from the ocean. Complex multi-level deck packed with dense industrial machinery: pipes, valves, pressure tanks, drilling equipment, cranes, antennas, helipad area (optional), staircases, railings, ladders, and interconnected metal frameworks. Weathered materials: worn steel, rust patches, chipped paint in yellow, gray, and industrial orange tones. High realism PBR textures (metal roughness, corrosion, oil stains, salt damage). Include intricate piping networks running horizontally and vertically, with visible joints and bolts. Add structural beams, trusses, and support frames under the platform deck. Large drilling tower (derrick) rising from the center with cables and mechanical detail. Secondary crane arm angled outward.
