In the last year Siebenhaar Antriebstechnik GmbH delivered six large scaled winches for a Cutter Suction Dredger to Jan De Nul Group. These are the main winches of the ship which are responsible for main lifting appliances.

 

1x Ladder Winch G6160 WH 04/0
1x Ladder Winch G6160 WH 05/0

The ladder winches, type G6160 WH, are used in the Cutter Suction Dredger for lowering or raising cutter head assemblies (boom systems). Both winches are installed below deck and are differentiated into starboard and port side execution.

 

Technical data:

Rope pulling force, nominal / max. value 1.150 / 1.650 [kN]
Weight 69.000 [kg]
Installation surface space requirements l x w x h 10,0 x 9,8 x 4,2 [m]

 

 

2x Spud Hoisting Winch 6180 WF 02/0

The spud hoist winches, type G6180 WF, are used in the Cutter Suction Dredger for lifting and free-fall mode operation of the main anchor spud. 

Free-fall mode: Out of a pre-defined height the spud drops to the sea floor penetrating it i. e. ramming the sea floor.

Lifting mode: In lifting mode the spud can be lowered to pre-defined height or can be pulled out from the ground and lifted to the deck.

 

Technical data:

Rope pulling force, nominal / max. value 1.750 / 3.500 [kN]
Weight 74.000 [kg]
Installation surface space requirements l x w x h 9,6 x 6,4 x 3,6 [m]

 

 

1x Side Wire Winch G6180 WH 02/0
1x Side Wire Winch G6180 WH 03/0

The side wire winches, type G6180 WH, are used in the Cutter Suction Dredger for lateral pull movements on the ship used to generate the required lateral feed for the cutter module (milling function). Both winches are installed on the working deck and are differentiated into starboard and port side execution.

 

Technical data:

Rope pulling force, nominal / max. value 2.000 / 3.000 [kN]
Weight 80.000 [kg]
Installation surface space requirements l x w x h 8,0 x 6,4 x 4,3 [m]

 

 

Siebenhaar will deliver further winch types for this project in year 2016.
