Patented technology for hard ground trenchingThe CBT3200 uses a patented trenching system to create an open vee trench for seabed protection and stabilisation of large diameter pipelines in hard ground. With triple chain cutters and four dredge pumps, CBT3200 has the power to produce trenches down to 2m in rock up to 40MPa compressive strength and still operate in soft seabed’s using a buoyancy system which reduces the submerged weight to 20 tonnes.
