A 10900 dwt Gogland is a trailing suction hopper dredger. It´s powerful pumps to dredge down to 30 metres below the sea surface. Dredging is made by suction with pumps able to handle 26000 cubic metres an hour. This material is then conveyed elsewhere, to be disposed by releasing bottom-locks of the ship. Alternatively, it can be pumped by pipes into barges or onto ashore up to one kilometer away.
Gogland is one of the largest ice-going dredgers in the world, it is 122 meters long, 22 metres wide and has the draught of 8 metres. Besides sophisticated dredging equipment, the ship boasts advanced electronic instruments and automation, including positioning and echo sounding.
