Benefits of Just-In-Time Sailing: how to take port operations to new heights

In heavy traffic areas reduced congestion and improved flow of vessels are important benefits deriving from just-in-time arrivals. A simulated study conducted by Wärtsilä on the Port of Singapore’s container operations showed that by optimising ETAs CO2 emissions can be reduced by 1,6M tonnes annually.


The benefits from enabling ships to arrive in port at the optimal time apply to port authorities, terminals, as well as for vessel owners and operators. Just-in-time arrivals:

  • Reduce congestion around the port area by shortening the time vessels need to spend at anchor waiting to berth
  • Increase navigational safety by reducing the number of vessels around the port area at one time
  • Reduce local emissions around the port due to decreased anchorage time
  • Create better data visibility for upcoming operations via digitally shared estimated arrival times (ETAs) for incoming vessels, and the possibility to communicate changed recommended arrival times (RTAs)
  • Allow for nautical services in ports to be streamlined - improving rest hour planning for the crew

Just-in-time arrivals enable more efficient planning of port and terminal operations.
