Beacon-Finland-JAK-ATB-Coupling-System

JAK ® Innovative Features Supervision Tested Performance Beacon has conducted an extensive series of model scale tests to gather basic data of the behavior of tug/barge combinations in different sea states. The tests have been carried out by the Ship Laboratory of VTT Technical Research Centre of Finland. Providing design data for each individual tug/barge sea state combination, the results form the basis for selecting the suitable size of the JAK ® ATB Coupling. The tests and the calculation method are recognized by major Classification societies. Higher Strength Materials Beacon Finland uses the highest strength steels in all of its’ JAK ® ATB Coupling Systems. For example the coupler pins are made of solid stainless steel. All of the JAK ® ATB Coupling’s equipment meets or exceeds the ASTM standards and ABS´ and other Classification societies’ requirements. JAK ® Hydralok System The hydraulic interlock system, HYDRALOK , is an attachment for the pneumatically operated JAK ® ATB Coupling System. The HYDRALOK system’s purpose is to significantly reduce, or possibly eliminate, the horizontal movement of the tug while engaged with the barge by “locking” the coupler pins, while in the extended position. The hydraulic pressure is produced by a separate hydraulic power unit and is controlled by an adjustable pressure relief valve. Control system: The HYDRALOK control system is integrated into the JAK ® control panels, which are located in the coupler compartment and the pilot house. The HYDRALOK system is operated manually. The release of the unit occurs automatically when retracting the coupler pins. Indication system: The control lights will illuminate automatically when the HYDRALOK system is activated. JAK ® Lightering System Beacon Finland Ltd has developed the capability of the JAK ® ATB Coupling System so that the tug remains in the notch of the barge during loading and unloading operations in harbor and calm sea conditions. The method is simple, as the Coupling System’s coupler pins remain extended in the vertical grooves of the socket plates, port and starboard, allowing the barge to move vertically, up or down.
