length of joint after depth has been reached due to the inability of the hammer to operate beneath the level of the upper deck is avoided and substantial savings in time and money are achieved moreover operation of the hammer at the level of the lower deck or below allows for utilization of longer length of pipe joint and hence savings in time taken for welding joints of pipe together and savings in time normally taken for cutting joints all of which results in substantial improvement in the economics of hammering operations from the foregoing it will be recognized that the pile driving rig of movable character as described in the afore mentioned preceding application when characterized by the universally angulating knuckle lead disclosed herein possesses market opportunity for the economic operations of driving a pattern of pile or conductor pipe in an offshore environment by moving the pile driving rig on the skids to predetermined positions on the platform the pile driving functions become readily accomplished without cumbersome movement of derrick barges likewise the elimination of a drill rig for such preliminary operations becomes advantageous substitution of the pile driving rig therefor for the derrick barge and drill rig produces market savings because of the substantial costs otherwise incurred moreover and further in accordance with the principles of this invention the utilization of the universally angulating knuckle lead mounted within the pile driving rig and supported thereby for angularly positioning a diesel or other hammer means significantly increases the versatility of the already.
