JAK® ATB Coupling System
Pneumatically actuated, electrically controlled articulated tug-barge coupling system in five sizes for tugs up to 10 000 hp and barges up to 35 000 tons.
Description
The JAK® ATB Coupling System connects a tug to a barge with two couplers, allowing tug and barge to pivot vertically independently and reducing forces in the joint. The original invention was made in 1991 and has been developed by Beacon Finland since. The standard P-type is pneumatically actuated and electrically controlled; a hydraulically actuated H-type is also available. Coupling is controlled from the bridge and/or a local panel in the coupler compartment. Pin loads were model tested at the VTT ship model basin in different sea states, speeds and angles of attack.
Key features
- No on-deck equipment and little space demand under deck
- Power consumption only 5 kW, using the tug's existing 24V DC and 425 psi compressed air supply
- Pneumatic operation with environmentally friendly oil lubrication
- Options: JAK® "Lightering System" (tug stays in the notch during loading) and JAK® "Hydralok" hydraulic interlock
- Scope of supply: application design, classification drawings for tug and barge, FEM strength analysis, two coupler units, two guide and socket plate assemblies, pneumatic valve panel, control system and instructions
- Installations accepted by ABS and LRS
Applications
- JAK®-100: sheltered waters, significant wave height up to 2 m
- JAK®-200: rivers and lakes, up to 5 m
- JAK®-400 / 700 / 1000: coastal and offshore, up to 7 m
