GB 17380-1998

This standard specifies the marking requirements, including colors, shapes, and lighting, for fixed and floating offshore structures such as platforms, wind turbines, and navigation aids in Chinese sea areas. It is applied to ensure the visibility and identification of these structures for maritime safety, preventing collisions by vessels and aircraft during day and night operations. The regulation is primarily used by engineers, surveyors, and regulatory bodies in offshore construction, oil and gas, and renewable energy sectors within China's territorial waters.
