SCAR in boulder clearance mode can remove boulders from a predetermined corridor from 10m wide in one pass. Demonstrated capability to significantly wider corridor using multiple passes to 20m and wider. SCAR Seabed Preparation/ Boulder Clearance Key Features: Proven capacity to handle boulders > 2m dia, rough terrain, mega-ripples Operated successfully in harsh work environments e.g. Laggan Tormore, Humber Estuary: launched in 3m significant waves; operated in strong currents; handled 300kPa. Removed gravel, cobbles and boulders up to 2m. Accurate positioning allows for safe deployment and avoidance of subsea structures if required. Unexploded Ordinance removal application Why SCAR? Subsea Trenching System SCAR Plough: Available configurations: - Seabed Preparation/Boulder Clearance - Trenching Plough pre-cut/post lay - Umbilical Plough (multi-pass) - Backfill Plough Variable Soils Capacity (clays, sands, gravel and silt) Economic cost per metre Expandable clearance width 5 to 250 tonne pull capacity – smaller tow forces allow smaller support vessels hence low fuel consumption, more efficient and reduced CO2 emissions Low Mobilisation Costs Can be launched and recovered from a range of vessels in high sea states - no A-frame required. No crane required if stern roller available Very high power to weight ratio Low bollard pull hence low fuel consumption, more efficient and reduced CO2 emissions Road/container transportable – available worldwide Steerability – proven ability to follow vessel route accurately Can operate in deep or shallow water and at shore ends <50m turning circle Decommissioning applications Suitable for both the Oil & Gas and Renewables sectors With rough terrain a speciality, SCAR is robust and reliable in conditions too difficult for conventional ploughs to handle. SCAR is simple, effective and low maintenance.
