A torque tool (10) for a subsea vehicle (such as a Remotely Operated Vehicle), a motor assembly (16), and a method of use are described. The torque tool comprises a tool housing, at least one torque drive head, and a drive mechanism operable to rotate the at least one torque drive head. The drive mechanism comprises a first hydraulic motor (17) having a first torque output and a second hydraulic motor (18) having a second torque output. The first and second hydraulic motors are operable to drive a common drive shaft (15). A preferred embodiment comprises a hydraulic motor interface device comprising a first interface surface on one side of the device configured to couple a hydraulic fluid supply to the first motor, and a second interface surface on an opposing side of the device configured to couple a hydraulic fluid supply to the second motor. |
