Abstract
A vessel (1) includes a spud (10), a spud lifting device (20) and a plurality of spud guiders (30). The spud guiders (30) are arranged to hold the spud (10) in a substantial vertical orientation and guide the spud (10) when moving in a substantial vertical direction between a lower position in which it can engage with a water bottom and an upper position. The spud lifting device (20) is arranged to lift the spud (10) from the lower position to the upper position. The vessel (1) further includes a spud position detector (40) to detect passage of the lower end (11) of the spud (10) along one or more spud detection points at predetermined heights.
