Bollard pull buoy is worlds largest
The largest offshore structure in the Mediterranean was recently positioned 12 nautical miles off the Ravenna coast in 25m of water in order to test bollard pull. The zone is a special area equipped for testing the power and efficiency of tugboats.
It was in this innovative offshore field, created by the Lucatelli company in Trieste on behalf of the Ravenna Port Authority, that the largest plastic mooring buoy in the world was placed. It is a 20 ton maxi Resinex float measuring 6m wide by 3.5m high and with 58 ton of net buoyancy.
Boats to be tested are hooked to the bollard pull maxi float, which in turn is controlled through an instrument which measures the load.
The jumbo buoy is a Catamaran Resinex type which was specially developed by the technical department of the italian firm in Adro (Brescia) in order to minimize oscillations in relation to the behaviour of the tugboats. Floatability and unsinkability are guaranteed by 24 plastic modules which are inserted in a steel structure which also hosts the balancing bollard pull levers.
The Resinex buoy is equipped with a Marimatech 250 ton quick release hook featuring a load cell which measures the mooring line tension with precision. The equipment includes a reception transmission system which communicates load data to the portable control unit positioned on the tugboat. The system, besides the precise monitoring of forces, is also able to release the hook from distance.
The big catamaran buoy is visible both day and night thanks to a Pharos Marine lantern and a ATONIS T3000 transponder.
