74Maritime Reporter & Engineering News TECHNICALDECK MACHINERY & HEAVY LIFTING Markey Machinery won the bid for a complete suite of winch systems onboard AGOR-27, the new academic research vessel being built by Dakota Creek Industries. Sponsored by the US Navys Of- fice of Naval Research (ONR), this contract is cen- tral to the need to rebuild the countrys aging fleet of academic research vessels, including ocean ranging vessels like the US Navys Knorr (AGOR-15). Markeys has been a long-term partner in this regard, having previously supplied equipment to the AGOR- 14 Melville (SIO), AGOR-15 Knorr (WHOI), AGOR-22 Moana Wave (retired), AGOR-23 Thomas G. Thompson (UW), AGOR-24 Roger Revelle (SIO), AGOR-25 Atlantis (WHOI), and the AGOR- NOAA vessel Ron Brown. Markeys participation was from the projects out- set, as it was to join Dakota Creek Industries and Guido Perla Associates, as ship board handling sys- tems integrator during the competitive design phase for the vessel in 2010. The order for Markey is for one ship set, including two type CAST6-125 Deep Sea Research Winches with active motion compen- sation, a type DETW-9-11 All-Electric Traction Winch System with two storage drums, one instru- mented flagging block, one ship board wire moni-toring system and a type WES-23 Electric Anchor Windlass with two wild cats and two warping heads. The type CAST6-125 is a third generation winch thatcan support research and explore depths with its drum capacity rated at 10,000m of 0.393-in. diame-ter electro-optical-mechanical cable. The winch fea- tures a close tolerance low mass moment of inertia drum for precise motion control of CTD/Rosettesampling instruments in sea state 5 environments. The feature eliminates unwanted ship motion, thus extending the life of cables for improved safety. The winches use direct coupled vector-duty 125hp non- proprietary electric motors.Features of the CAST6-125 include:?A motor-driven precision level wind system. A pushbutton operator interfaces enables the level wind to electronically adjust to any diameter wire, cable or softline.?A two sheave instrumented fairlead head that eliminates reverse bends. The elimination of one sheave in the cable path and all reverse bends will effectively extend the service life of expensive, fragile cables.?The output sheave of the fairlead is mounted in a flagging block which sweeps 360 degrees. This unique design eliminates the need for deck handsto carry and rig intermediate blocks or fairleads, resulting in less time spent rigging, more time forsampling, which reduces overall operational time and expense. ?A single speed transmission coupled with AC variable-frequency speed controllers improves re- liability and are more efficient, while requiring less maintenance than hydraulic powered ma- chines. www.markeymachinery.com Markey Wins AGOR-27 Deck Machinery Deal Kraaijeveld DeliversWinches to Dockwise At the beginning of March, two special Kraaijeveld windlasses arrived in Korea, in- tended for the Dockwise Vanguard, a semi- submersible heavy vessel which is going to be built for Dockwise. In itself nothing spe- cial, except that the winches are quite sub- stantial in size and will get a special positionin the Dockwise Vanguard. Kees Kraai- jeveld, general manager at Machine- en Lierenfabriek C. Kraaijeveld in Sliedrecht, said: "In one way or another, the winches nowadays are getting bigger, more cus- tomized and more complicated as well." The dimensions of the winch: length 4.5m, width4,5m and height 4m; weighing 90 tons andsuitable for a chain diameter of 157mm, arecurrently the largest chain size available. In addition to the two winches, Kraaijeveld has also delivered the hydraulic drive and the chain stoppers. Both the ship and thewinches had to be delivered in a very short period of time.

It has beentested in the worlds largest offshore wind turbine park,London Array. Even better: only one em-ployee is needed tohandle and adjustthe TP. The type CAST6-125 is a third generation winch
