Dobbel Drum Winches

Motors The workhorse of our AHT winches is the radial piston hydraulic motor. This motor has up to 98 % volumetric efficiency under ideal operating conditions. It has proven to function well in many tough applications in In both heavy landbased industry and in the offshore industry. The motors are fitted with custom made load holding manifolds which have several functions. The manifolds will close the lift side if the pressure in the lowering side comes down to a pressure where cavitation could occur. This ensures that the load is held if a pipe is ruptured and also makes sure that the motors never can cavitate. In addition to the load holding function, the manifolds are equipped with a free-wheeling function that can rapidly let the motor rotate freely without any torque being transferred. The manifold also includes pressure relief functions and boost pressure inlet.


Triple Drum Winches

flow from the HPU can be used by fewer motors, creating a higher rotational speed. This is very useful if a light load is being used or if the wire without load needs to be rapidly raised from the seabed. The motors active in different steps are changed automatically to have an even wear of all components. The gearing is fail-safe and does not allow activation if the actual load is too high for the requested gear step. Safety Safety is a key issue. The hydraulic system has several safety features and important functions which are backed up by battery power and sometimes by energy stored in accumulators. All critical functions are hardwired to work even if the control system for some reason is inoperable.

Main control valve The motors are being controlled by a high response industrial proportional valve. This very fast and accurate valve enables us to control the rotational speed and requested pressure acting on the motors. Gear steps The free-wheeling function is also used to create different gear steps. By disconnecting one or a number of motors, the entire 9


SECONDARY WINCHES NDM offers a wide range of secondary winches for AHTS vessels. These winches can be delivered in various configurations and with various pull and brake holding capacities. The secondary winches combine large storage capacity of wire and rope with higher pulling force. The secondary winches can be used for transfering wire and rope to other winches while maintaining a solid back-tension and thus enabling a higher force used on the wire and rope during deployment.

Features Drive: Hydraulic Configuration: Single drum Rated pull (1st layer): 100–200 T Speed: To suit operational requirements Clutch: Hydraulic operated Brake: Hydraulic operated band brake Control: Local and/or remote control

An AHTS vessel normally consists of one (1) or two (2) secondary winches where each of them has a storage capacity of up to 1600 m Ø 203 mm synthetic rope or up to 4000 m or Ø 76 mm steel wire. Our secondary winches are delivered with a pull capacity from 100–200 T. These winches are always equipped with a spooling device to ensure safe spooling onto the drum.



Stern rollers NDM delivers a unique and revolutionary stern roller, short ended type. The short ended stern roller operates as any other stern roller. But what’s unique is the labor and cost saving way the short ended stern roller is attached to the ship’s hull. The unique way of attaching the short ended stern roller, is due to the fact that the shaft is the same length as the stern roller itself, and is fastened to the ship’s hull by means of a welding flange and a fastening flange bolted to the shaft and welding flange. One flange is welded to the shaft, while another flange is welded to the ship’s hull. This enables the roller to be installed much more efficiently than with a more traditional solution. The same advantage is off course prevailing if the roller needs to be removed for maintenance or adjustments.

Single model

Our stern rollers can be delivered from SWL 50 T (single models) and up to SWL 750 T (double models) to fit all types of AHTS vessel and capable of working on all required loads.

Double model

Advantages • • • • •

No steel work is necessary after the welding flange is attached to the hull A man hour reduction of minimum 75 % compared to a traditional roller during installation When dismounting and mounting the stern roller, there is no need for steel cutting or grinding to get the stern roller out By using pressure lubricated bearings, the stern roller will turn with a minimum of friction All in all, the short ended stern roller will be beneficial for both the shipyard (during installation) and ship owner (during operation and maintenance).

This load is achived by securing the winch rope to a fixed point and then locking the winch directional control lever into the pay-in-position.



The winch will hydraulically stall at the pre-determined pay-in-load setting. If the winch should be influenced by a greater external force than that the pay-in load setting, the winch rope effectively pulls from the winch drum. When the external force sunsides to less than the pay-in load setting, the winch will automatically pay in whilst keeping constant tension within the winch rope. Our constant tension are normally delivered with a pull (1st layer) of 5–10 T but other models can be delivered.
