Confirms a clean departure from the origin port and establishes the first credible ETA/ETD pair that seeds pilot, tug, and berth planning in Rotterdam. Shares the vessel’s key particulars and any constraints that influence berth selection, then initiates continuous ETA refinement using live voyage intelligence. The aim is to set a reliable baseline for all downstream commitments. Getting this right limits knock-on replans and protects schedule integrity.

Issues an early, lightweight intent to call that provides core identifiers, timing, and any relevant risk indicators. This enables the port and terminal to provisionally allocate capacity, begin preliminary safety screening, and lets agents line up critical services and documentation. As routing and weather evolve, the notice is iteratively sharpened to keep plans aligned while preserving flexibility. The goal is early visibility and fewer late surprises.

Converts intent into a formal request for berth and operations in line with local procedure. It locks preliminary ETB/ETD windows, triggers required regulatory and operational submissions, and reserves pilot and tug windows subject to confirmation and conflicts. Roles, messages, and cut-offs are clarified from this point forward. The outcome is an executable, synchronized port-call plan that all parties can operate against.
