ANCHOR HANDLING MOORING WINCHES
DMT MARINE EQUIPMENT has impressive track records in the Designing, Manufacturing, Installation and Commissioning of all kinds of winches for the Civil, Maritime and Hoisting industry according to the latest rules for Lifting Appliances in the Marine environment.
For transferring Barges, Pontons, Ships, Jackups and Semi-Subs in open Sea without a DP-system a Constant Tension or Mooring system can be used.
The floating construction can be equipped with the following CTM (Constant Tension Mooring system):
CTM 4 - Four point mooring system
- 4noswinchesarepositionedinfourcorners.Thefloatingconstruction can be transferred forwards, backwards and side ways with the help of fairleads,all at the same time.- Forsmallfloatingobjectsandlowwaterlevel(uptoabt.20mtr)DMT Spud Pile system can be used.- The Mooring winches are provided with steel wire ropes and can be equipped with an auto Level-Winding spooling device.
CTM 6 - Six point mooring system
- 4 nos Winches are positioned on each corner and the other two winches sidewards at SB and PS. The DMT CTM winches can be driven by Diesel Electro Hydraulic/ Electric power source.
CTM 8 - Eight point mooring system
- 8nosDMTwinchesarepositionedoneachcornerand2nosatSBand2 nos at PS. This system is mainly mounted on Large Semi-Subs, and are also being used for anchoring.- Thewinchesareprovidedwith1000to2000mtrsteelwireandanchors will be drop with the help of an Anchor handling supply boat.

Each DMT winch is laid out for Anchor Handling and Mooring purpose (AMW) are electric driven and the installed power is based on a nominal line pull of 30mT,amax.linepullof60mtwithalinespeedof10m/minonall(8nos)layers.Staticholdonthefirstlayer100mtandthewinchdesignisbasedonalinepullof200T.Theinstalledpowerperwinchis150kw(2x75kw).
The line speed is fully proportional controllable with the Frequency drives between10M/minand20M/minofspeedduringhaulingandreevingatconstantpower.
The installed frequency converters are equipped with air or water coolers, the brake resisters cooled with air or water.
To keep tension on all cables and to maintain the barge in a tight spread of six cables ant to maneuver the barge /vessel in any direction the winch.
