Winter weather at the Black Sea ports: planning discharge windows

The western and central Black Sea ports share a problem: they face north, and between November and March the north is where the weather comes from. Operations suspend, vessels leave the berth, and a discharge that was planned for three days takes seven.

What actually stops work

It is rarely wind alone. It is swell entering the harbour and making the vessel move against the fenders, which stops crane work long before conditions look dangerous from ashore. Vessels are sometimes ordered off the berth to ride it out in the roads.

Plan the discharge, not the arrival

Arriving on time into a weather window that closes the next day helps nobody. Where the cargo allows, we plan around the forecast window rather than the ETA — sometimes recommending that a vessel waits at anchorage for a day to start into a clear stretch rather than beginning a discharge that will be interrupted.

Laytime consequences

Weather working days and the treatment of suspension periods vary by charter party. Statements of fact need to record the start and end of every weather stoppage precisely, with the reason. Reconstructing this after the event is where laytime disputes begin.

Practical steps

Ask for a forecast-based berth recommendation before fixing the laycan, keep the statement of facts current daily rather than at the end, and expect at least one interruption on a winter call. Planning for it costs nothing; being surprised by it costs demurrage.
