The striking caused considerable damage to the protection pier and swing span of the bridge. Rail traffic over the bridge was interrupted until 30 June 1999. Marine traffic through the swing span was suspended until the same date when it was made available on a limited basis. Unrestricted maritime use of the swing span was not available until 26 July 1999." "The Sheena M is a steel tug with the superstructure forward and a towing winch located on the centre line of the main deck behind the superstructure. Two diesel engines driving two reversible propellers constitute the propulsion system which is entirely controlled from the wheelhouse. The towing winch on the Sheena M is situated on the after deck, approximately one-third of the vessel's length from the stern. The drum of the towing winch contains approximately 180 m of 250 mm diameter tow wire connected to two 220 mm diameter towing bridles, each approximately 13 m in length.
