Dutch manager Chemship has said the cause of a collision between one of its tankers and a passenger vessel is not yet known.
The 14,300-dwt Chemical Marketer (built 2004) and river cruiseship Viking Idun were damaged above the waterline on Monday in the Westerschelde in Terneuzen.
Chemship said that following the impact a number of passengers on Viking Idun suffered injuries and had received medical attention.
"No pollution has occurred as a result of the incident. Both vessels have sustained damage above the waterline and are in a stable condition. A full assessment of the damage will follow later," it added.
"Regardless of the exact circumstances of the incident Chemship would like to express its deep concern over the injuries to the passengers and disruption to other guests on board of the Viking Idun. Also the company would like to thank the local authorities for their swift assistance."
Immediately after the incident Chemship informed all relevant authorities and parties, it said.
"The exact cause of the incident is yet unknown," it added.
A full investigation will follow, to which Chemship will offer its full cooperation.
Chemical Marketer has meanwhile moved under its own power to the port of Flushing awaiting further instructions.
A superintendent of the company will be attending to the vessel shortly, Chemship said.
The tanker was carrying a cargo of aromatics from Iskenderun, Turkey, to Antwerp.
