MacGregor has decades of experience in oceanographic winch design combined with cutting-edge drive and control expertise from offshore and subsea operations.
For example, our winches on the German research vessel Meteor are still on duty after 30 years of operation, providing reliable, safe load handling. MacGregor winches have also been chosen for the youngest research vessel Sonne II, and have already been successfully used to bring up sediment samples from a depth of over 9,500m.
With our range of designs for both direct pull and traction winches, we can handle the most common scientific equipment such as CTD (conductivity, temperature and depth) rosettes, corers, sledges, plankton nets, and fish sonars. Usually, only few adaptations are required to meet your specific requirements. If you have a specialist application, we can provide you with references for completely customised winches to give you some idea of our broad capabilities..
Water-cooled, frequency-controlled electric motors provide extremely accurate winch control. For delicate operations such as video-monitored seabed sampling or to increase the weather window for your operations, we offer active heave-compensated winches that make use of MacGregor's lengthy experience and excellent reputation with subsea cranes.
Depending on your personal preferences and the characteristics of your application, you can use cutting-edge permanent magnet or traditional asynchronous motor technology. If you prefer, we are also happy to offer high-pressure hydraulic drives as an economical alternative.
Together with market-leading suppliers of deep-sea cables, steel wire and fibre ropes, we will help you make the right choice of product for your application and, if needed, provide advice regarding the required performance parameters. Our winches are delivered with the cable or rope installed, including slip ring, termination and splice box according to your specific requirements.
