MD3/HD3/UD3FLEXIBLE SLOT PLOUGHSThe Smart Plough range including the Multi-Depth Plough (MD3), Heavy Duty Plough (HD3)and Ultra Duty Plough (UD3), is recognised globally as setting the standard in cable ploughing,reliably trenching in most soils including sands, clays and soft rock. The range is designed tohandle cables up to 150, 200, 300 and 400mm diameter electrical cables and repeaters fortelecommunication systems. The ploughs come with a further range of cable MBR capabilityfrom 1.5m to 6.0m.Using patented technology, the ploughs are designedto minimise pull force requirements and provideeffective trenching capability from zero to 4m depth.Their performance can be enhanced with jetting androck ripping upgrades. Coupled with a tow winches,umbilical winches and wide angle A frames, SMDare able to supply a turnkey flexibles burial solutionfor a wide range of cable sizes and vessel tow loadtogether with cabel and handling systems suchas drum cable engines (DCEs) and linear cableengines (LCEs).FEATURES• 80 –250te max pull capability• 2-4m max trench depth capability• Product burial from 150 to 400mm dia.,1.5 to 6.0m MBR• Diverless subsea unloading• Diverless subsea loading• Emergency cable unload• Multi depth burial capability• Steering bridle +/- 12 degrees• Jetting system for enhanced burial in sand• Jetting thruster for positional accuracy whenlanding on seabed• Comprehensive instrumentationand surveillance• Optional kit for beach operations• Proven Curvetech TM components throughout• DVECS robust distributed control platormprovides reliable, ergonomic operaonsand good diagnostics• Range of SMD designed A-frame based LARSfor standard and high sea states• Containerised control and power system
