Title: CHAIN DRIVEN DIAMOND WIRE CUTTER
Abstract:
A diamond wire cutter (100), using an adjustable length pulley system, a diamond wire saw (1), and a movable pulley cart (10), can perform a through-cut of complete sections of a structure such as a tubular (200) subsea by fitting a chain about an outer surface of the structure, securing the chain to the movable pulley cart and using the chain to move or otherwise guide the movable pulley cart about the outer circumference of the structure to cut while using a diamond wire (50) to effect a cut between the movable pulley cart and the diamond wire saw (1).
