Maersk had chartered the ship, which according to ship operator Rickmer Shipmanagement is owned by undisclosed private investors. The company met with Iran's Ports and Maritime Organization on Wednesday and said the company "must presume" the seizure was related to the dispute.
"We must insist that the crew and vessel are released as soon as possible. The crew is not employed by Maersk Line, nor is the vessel owned by Maersk Line. Maersk Tigris and its crew are thus not in any way party to the case."
Maersk, the world's biggest container shipping line, said it had agreed to pay an Iranian company $163,000 after an Iranian court ruling in February which related to a dispute about 10 container boxes transported to Dubai in 2005.
"Only today, 30 April, have we learnt that the appeal court has ruled Maersk Line to pay $3.6 million. As we do not have the details of the ruling, we are not able to comment hereon,
