JIT Arrival Guide backs low carbon shipping

The Guide has been developed by the IMO’s Global Industry Alliance to support low carbon shipping (Low Carbon GIA). It documents the findings of a series of industry roundtables which brought together nearly 50 companies and organisations that are key stakeholders in the port call process.

Widely recognized as a means of increasing port efficiency and port call optimization, the successful implementation of JIT Arrivals can have a significant environmental impact through reduced GHG emissions from optimizing the ships speed to arrive just in time.

The concept is based on the ship maintaining an optimal operating speed, to arrive at the Pilot Boarding Place when the availability is assured of: 1. berth; 2. fairway; and 3. nautical services (pilots, tugs, linesmen).

Arrivals also contributes to reduced time at anchorage and therefore reduced congestion in the port area. It is estimated that ships spend up to 9% of their time waiting at anchorage, which could be reduced through the implementation of JIT Arrivals.

The Low Carbon GIA operates under the framework of the IMO-Norway GreenVoyage2050 Project.
