The Portable Top Drive System (PTD) was developed as an attempt to introduce Maritime Hydraulics into new markets worldwide, and so far it seems like we have succeeded. Maritime Hydraulics are now able to offer well proven technology to the Land rig and compact Offshore rig market at a reasonable cost. Maritime Hydraulics utilities its expertise, gained from the beginning of a major offshore drilling equipment supplier, when recently developing the Portable Top Drive System (PTD). This system is a tailor made but at the same time, standardized product which allow the operators of Land rigs and Compact Offshore rigs to enjoy all the benefits the Top Drive Drilling Technology offers and a reasonable cost. The Top drive gearbox is an integrated assembly including a main gear and one or two pinions complete with seals and bearings. For greater drilling torque, an additional motor and pinion or bigger motor(s) are mounted on the gearbox. The various combination of motors enable the PTD system to give various drilling torque on speed output. Advantages of Top Drive Drilling A Safer Drilling Operation: • The top drive make-ups and breaks-out many connections, thereby reducing the hazards of rotary tongs and spinning chain. Remote operated Kelly valve reduces ( optional ) mud spillage when back reaming or breaking off after circulating above the rig floor. Reduce total drilling costs by increasing drilling efficiency. Connections made up by the Drilling motor using the Torque Arrestor as back-up. During side-track operations, drilling operations can be performed with stands. Saves survey time. If no radical changes arise in the downhole technology, the Top Drive Systems will continue to be the predominant method of drilling offshore wells also in the future.
