DCSA Publishes Complete Framework of Just-in-Time Standards for Main Port Call Activities

Press Release on Shipping and Freight ResourceLatest release of DCSA’s Just-in-Time Port Call Programme provides interface standards and API definitions for all 50 port call event timestamps.

This might also be something that can assist with this so called “unscheduled” and “unannounced” calls of the vessels chartered by the likes of Walmart and Amazon which are reportedly adding to the backlog of ships at the US ports.

AMSTERDAM, November 16, 2021 – Digital Container Shipping Association (DCSA), a neutral, non-profit group established to further digitalisation of container shipping technology standards, in conjunction with its nine member carriers has published interface standards and messaging API (application programming interface) specifications for all 50 event timestamps defined in its port call data definitions, which address the 6 main parts of a port call:

  • Berth arrival planning
  • Pilot boarding place arrival and service planning
  • Pilot boarding place and berth arrival execution
  • Start cargo operations and services
  • Services and port departure planning
  • Port departure execution

The interface standards allow carriers, ports, terminals and other service providers involved in a port call to exchange event data in a uniform way, enabling automated data exchange. The complete framework of Just-in-Time Port Call standards supports digital port call planning, increased operational efficiency and optimal resource utilisation.

It is the next major milestone in the effort to achieve a more transparent vessel voyage ecosystem following the 2020 publication of DCSA Standards for Operational Vessel Schedules, which enable automatic sharing of schedule information between vessel operators and their partners.

By moving container shipping towards a more efficient port call process, DCSA standards enable container ships to optimise their steaming speed, thereby lowering fuel consumption and reducing greenhouse gas emissions. To provide a global industry framework that preserves investments, DCSA collaborated with ITPCO¹ and IMO² to align port call data definitions to existing standards.

The standards are being tested by carriers, ports and terminal operators at multiple ports around the world. These tests will help DCSA ensure its standards address the needs of stakeholders. All API definitions are available to download for free from SwaggerHub, and reference implementations are posted to GitHubDCSA Port Call Data Definitions can be freely downloaded from the DCSA web site.

Achieving just-in-time port calls requires accurate, real-time communication between carriers, ports and terminals,” said Phanthian Zuesongdham, Head of Division Port Process Solution of Hamburg Port Authority.

DCSA digital standards are key to enabling this level of communication on a global scale. We are excited to be part of this effort to test the efficacy of their standards for optimising a very important container shipping process. As Germany’s leading transhipment hub, this collaboration is another example of our ongoing effort to maintain and extend our leadership position by adopting state-of the-art technologies and fostering innovation for our business and the industry at large.

Customers of shipping services want visibility and predictability; having a complete set of standards for port calls is an important step towards improving the efficiency and accuracy of data exchange between all parties,” said Thomas Bagge, CEO of DCSA.

The port call is the perfect way to showcase how critical it is to have an interoperable technology framework that enables seamless communication and cross-stakeholder collaboration. By adopting DCSA standards for Just-in-Time Port Calls, Operational Vessel Schedules and Track & Trace, the industry will see an emerging digital ecosystem where these activities turn into collaborative, data-driven, digital processes. 

Carriers, ports, terminals, service providers and customers of container shipping alike will gain efficiency, cargo visibility and cost savings. Digitalisation also improves sustainability through better communication and planning, thereby reducing fuel consumption, greenhouse gas emissions and paper waste. We are committed to helping all industry stakeholders adopt DCSA standards and realise value for their organisations.
