I apologize for the confusion, but it appears there's a misunderstanding regarding Saphan Plazao Udom in Thailand, Laem Chabang. From the information available to me up to 2023, Saphan Plazao Udom does not specifically pertain to a beach but may refer to an area or infrastructure-related to Laem Chabang, which is known for its port facilities rather than recreational beaches. Laem Chabang is more notable for being Thailand's main deep-sea port, focusing on shipping and industrial activities.
