According to DynaLiners, Ellerman had previously participated in CMA CGM’s PGE service.  

The new service maintains direct connectivity between the United Kingdom, the Netherlands, and Portugal; however, Aveiro will replace Leixões and Setúbal as the sole Portuguese port of call.  

The INEX1 port rotation is as follows:  

London Gateway (Tilbury) → Rotterdam → Aveiro → London Gateway (Tilbury)  

The service will be operated by a single 500-TEU container vessel on a regular, repeating schedule.
