The SPIDER system was developed for the excavation of the escarpment area on ORMEN LANGE.

The 30 degree slope required a pre dredge trench of 10 m and 4 m deep in 30 degree slope.In the stiff to hard seabed, the SPIDER dredged these sectiion successfuly in 2005.The terrain dredger system was based on the idea of the Menzimuck terrain forester machine,

and is classified as walking machine.The SPIDER has proven capacity in up to 300 kPa soil, can handle boulder up to 10,

and has an arm with reach of 6 m. It maneuvers with both use of thrusters orby the use of the walking legs.

Further it has a fully operational VR control system,and all operation are done in 100% VR and with no requirement of any visibility.
