The Haven Seaway is shown passing in front of the Cruise Terminal 2 building on the Admiralty Pier in the Western Docks of Dover Harbour at 7.31 am, Monday, 16th of August 2010.

The barge is being towed to the Jetfoil Basin by the MTS Vengeance tug, out-of-shot to the right.

The photo was taken from Lighthouse and Cafe end of the Prince of Wales Pier.

The Haven Seaway is owned by Red7Marine (R7M, a provider of offshore, coastal and estuarial subsea engineering and marine construction) who describe it as a "Mono-hull Jack Up Barge" (see Jack Up Rig).

The Haven Seaway joins the Haven Seafield Flat Top Barge who is assisting the Waasland Sea Barge and the Gaverland Sea Barge (both owned by Herbosch Kiere Marine Contractors) in removing the wreck of the Spanish Prince (see wreck site and sonar image photos), a blockship scuttled in early 1915 during the First World War.

The Haven Seaway Mono-hull Jack Up Barge only stopped overnight and didn't appear to have anything to do with the Spanish Prince blockship removal.

When in range of AIS, the vessel's current position is shown at:

The Haven Seaway Barge (IMO 0, None)

The Automatic Identification System (AIS) is an automatic tracking system used on ships and by vessel traffic services (VTS) for identifying and locating vessels by electronically exchanging data with other nearby ships and AIS Base stations. AIS information supplements marine radar, which continues to be the primary method of collision avoidance for water transport.
