Abstract
The operators' visibility of underwater construction equipments plays a key role for safe and efficient construction. The visibility can be limited within 30cm in the West Sea of South Korea where water is considerably turbid. This paper investigates the appropriate location and projection angle of light to be used for construction equipments using model tests. It was discovered that visibility was obtained when the light was located near the target objects with a projection angle of $45^{\circ}$.
