A short delay was necessary to allow time for some minor adjustments to be made to the video equipment before the vessel sailed at 1230. Once in deep water to the north of Fraserburgh, the initial task of stretching and improving the lay of the umbilical on the TV winch was carried out by deploying the sledge and most of the cable then recovering the equipment under tension.
