What are the dimensions of the GREEN signal flag used during well deck operations?

The dimensions of the GREEN signal flag used during well deck operations are specifically standardized at 3 feet by 3 feet. This size is significant because it ensures visibility and clarity, facilitating effective communication during operations where safe handling of smaller crafts or personnel is critical. The well deck area often involves complex maneuvers, and a flag of this size ensures that it can be seen from a distance, allowing for timely responses and actions by crew members on board and those in the surrounding area.

Using standardized flag sizes helps maintain uniformity across different vessels and operations, ensuring that all personnel receive the same visual communication cues regardless of the platform they are working on.
