Fast Ann a decommissioned and unmanned cargo vessel waiting to be dismantled, parted her moorings on an ebb tide in dense fog in the River Humber. Her radar echo was acquired and tracked by Humber Vessel Traffic Services (VTS), who made several unsuccessful attempts to establish communications with the unknown contact. A pilot vessel and two tugs were then tasked to investigate. One of the tugs managed to identify the vessel and made fast a tow line to her stern. Dense fog and a strong ebb tide of about 4 knots hindered the efforts of the tug, which could not prevent Fast Ann from making contact with the Immingham Oil Terminal structure.
