Parkeston Quay (Port Code:GBPAQ), now known as Harwich International Port, is a North Sea seaport in Essex, England, and one of the Haven ports. It lies on the south bank of the River Stour one mile upstream from the town of Harwich, opposite the Port of Felixstowe. The main user of the port is the regular ferry services of Stena Line who run twice daily passenger and freight services to the Hook of Holland; as well as freight only services to Rotterdam Europort. The main vessels serving the port are the RoPax ferries the Stena Hollandica and the Stena Britannica, and the RoRo ferries.
Cruise ships once called regularly at the port during the summer months, although in recent times these calls have become more and more infrequent. The year 2016 saw 12 visits – the lowest since the service started. While the majority of opinion puts this down to the recent economic downturn, others feel the reason is due to the lack of facilities for visitors when compared to the likes of Southampton or Dover. Tankers call at the Carless refinery, and some general cargo and bulk cargos are worked at the port.
There are four ro-ro berths with linkspans. The specialised pier for the High Speed Ferry Discovery is disused now that the high-speed ferry service has been discontinued and its linkspan has been removed. There are extensive railway sidings adjacent to and within the port with 40 acres of standing for cars including electric vehicle charging points. In total, there are over 105 acres (0.42 km2) of operational land with parking for over 1,000 trailers.
