To facilitate implementation of its just-in-time (JIT) port call standards, the Digital Container Shipping Association (DCSA) released interface standards and messaging API (application programming interface) specifications for the first 18 event timestamps defined in its JIT port call data definitions. The interface standards enable automated data exchange between carriers, ports and terminals for the five main phases involved in any port call. Those phases include berth arrival planning, pilot boarding place, start of cargo operations, cargo operations and department planning, and berth departure execution. The standards are being tested at two unnamed ports to gather feedback on how to ultimately improve them and drive widespread adoption. Eventually, DCSA plans to release a broader set of 50 event timestamps to be standardized as part of its broader JIT Port Call Program.
