Apparatus for synchronizing movements in anchor cable and a load cable
Abstract
Abstract VESSEL WITH AN ANCHOR WHOSE CABLE IS DRIVEN BY A FIRST WINCH AND ANOTHER LOAD SUCH AS A DIVING BELL WHOSE CABLE IS DRIVEN BY A SECOND WINCH, HAS A SWELL COMPENSATOR FOR EACH OF THE TWO CABLES, THE COMPENSATORS BEING INTERCONNECTED TO PREVENT MOVEMENT OF THE LOAD RELATIVE TO THE ANCHOR. THE TWO SWELL COMPENSATORS ARE COUPLED HYDRAULICALLY. THAT OF THE ANCHOR CABLE CAN COMPRISE A HYDRAULIC CYLINDER CONNECTED TO A PRESSURE VESSEL ON ONE SIDE AND TO A HYDRAULIC CYLINDER OF THE COMPENSATOR FOR THE LOAD ON THE OTHER SIDE. ALTERNATIVELY, THE WINCHES CAN BE INDIVIDUALLY COUPLED TO POSITIVE-DISPLACEMENT HYDRAULIC MOTORS WITH ONE SIDE OF THE ANCHOR MOTOR CONNECTED TO A PRESSURE VESSEL AND THE OTHER SIDE OF THE ANCHOR MOTOR CONNECTED TO ONE SIDE OF THE LOAD MOTOR AND WITH THE OTHER SIDE OF THE LOAD MOTOR CONNECTED TO A RESERVOIR FOR HYDRAULIC FLUID.
