Real time position and report data from ships can be used to improve port related decisions. The document discusses using Automatic Identification System (AIS) data and other datasets like port manifests and customs records to analyze areas like port congestion, unloading times, and route management. It provides details on AIS data collection and encoding/decoding messages to represent vessel movements and analyze ship traffic and routes at UK ports as a test case.

1. Real time position and report data
from ships for better decisions
in collaboration with
Center for Big Data Statistics (CBDS)
Dr Ioannis Tsalamanis

2. The Challenge
• Shipping and trade are of great importance to the economy of the UK
• Can we use real time big data sources to improve port related decisions?

3. Freight Statistics
Inward Traffic Outward Traffic
Department for Transport, Statistical Release, 1 September 2017

4. Areas of interest
Port congestion
Unloading and
Reloading times
Storage capacity
Transportation
of goods
Route management
Customs delays

5. Datasets
• Automatic Identification System (AIS)
• Consolidated European Reporting System (CERS)
• Port manifests
• Customs records
• Big freight companies
• Official surveys

6. AIS data
• Maritime navigation safety communications system
• Can be used to spatially represent vessel movements
• Class A messages from large ships (>300 tonnes) and all passenger ships
• Class B messages from smaller ships, fishing ships and recreational vessels
• 27 different types of messages (position, status, voyage, aid required, …)
• Every 2 seconds from moving vessels
• Up to 3 minutes from from anchored or moored vessels

7. Encoded messages
