A subsea diamond wire saw uses a diamond-embedded wire, driven in a continuous loop, to cut through steel sections too large or complex for a single-jaw shear. Unique Group’s Ren Diamond Wire Saw range covers 20-inch, 26-inch, and 30-inch cutting capacities, cutting multi-string casings, heavy wall tubulars, structural members, and complex pipe systems. Typical work includes pipeline, casing, and riser severance, jacket leg, caisson, and pile removal, and cuts on subsea structures and templates during decommissioning, salvage, and emergency intervention. The 20-inch model is fully ROV-operated and offers time savings and cut quality over traditional cut-and-grind methods. All models are available for rental.
