Division 2.3.2.2 Lock planning, medium-term

Medium-term lock planning is dealing with the planning of a lock up to two or four lock cycles ahead.

In this case the traffic information is used to map the arriving vessels to the available lock cycles and based on the planning to inform the conning skippers about the RTA.

ETA shall be available on request or shall be exchanged if the deviation from the original ETA exceeds the deviation allowed by the competent authority. All other information shall be available once at the first contact or on request. RTA is the response to an ETA report or may be sent from a lock to propose a locking time.
