Woods Hole Selects Rapp CTD Winch

Posted by Irina Tabakina

Rapp Hydema provided Woods Hole Oceanographic Institution (WHOI) a CTD winch for its new research vessel R/V Alucia, which is being managed and financed by Beta Maritime.  Rapp’s TBW-520E-T90 winch accommodates 7,000m of .322 Rochester Fiber-Optic cable, plus 100 ft. of 2.25-in. synthetic tether.  It has Active Heave Compensation (AHC) set for optimal use at 3000m of deployed line.   Rapp’s unit is compliant with UNOLS’ Research Vessels Safety Standard Appendix B:  Overboard Handling Systems Design Standard, a rigorous requirement that is only now in the process of implementation fleet-wide.  The Rapp winch develops five tons of line pull in Speed Step 1, on the bare drum, while retrieving at 60m/min. 
Despite the presence of Active Heave Compensation, the Rapp winch has a power requirement of 70 kW with 3000m of line deployed.  Rapp’s electrically-driven, electronically-synchronized T90 level wind—popular in various other research vessel applications—is also used.
