Powerful and easy-to-use

How it works


Get Your API Key

Fill-in the form below to obtain your credentials. Free trial is available.


Select Your Vessel

Using IMO or MMSI, select the vessel you wish to calculate emissions for. 

This allows us to retrieve key information such as vessel type, current position, speed, fuel type and historical performance.


Select Route

Select Port of Departure and Port of Destination. 

This allows us to compile routes that can be taken by the vessel and assess distance, time to go and port congestion. 


Answer Format

The response will provide an estimation in tons of CO2 emitted per TEU for the specified voyage. 


The calculated information available in the estimated time of arrival Module are: 

  • The estimated time of arrival of a vessel in a port  
  • The route time 
  • Statistics of the ship on this route

Our machine-learning software combines the data obtained from a ship’s AIS (Automatic Identification System), with historic voyage data and metocean data to precisely calculate the next port of call of a ship and its arrival time.

To go further on this question :

How Is ETA Computed Using Artificial Intelligence?

The estimated time of arrival Module is a “plug-and-play” solution.  

Thanks to 4 Steps, the results are delivered within a span of a few seconds. 

Sustainable development Goals

Sinay is committed to the fight against pollution and climate change thanks to innovative technology. Reduced port congestion and an optimized supply chain help maritime traffic to be more efficient and more respectful of marine biodiversity.
