What is the main purpose of vessel traffic services?

The main purpose of vessel traffic services (VTS) is to provide navigational assistance and coordinate vessel movements. VTS acts similarly to air traffic control for marine traffic, ensuring that vessels navigate safely and efficiently in busy waterways. By monitoring vessel movements and communicating with mariners, VTS helps prevent collisions, manage congestion, and facilitate smoother passage through navigational channels. This coordination is crucial in areas with significant maritime traffic, where effective management can enhance safety and efficiency.

The other options, while relevant to maritime operations, do not encapsulate the primary function of vessel traffic services. Monitoring environmental conditions is important but is typically a separate function conducted by environmental agencies or other entities. Facilitating the loading and unloading of cargo pertains more to port operations and logistics than to VTS. Training new mariners is vital for safety at sea but falls outside the scope of VTS, which focuses on navigation and vessel coordination rather than training.
