Roll damping system designs as especially tank and filling the tanks to create a stabilizing moment opposite to wave motion. Fishing vessel designs usually consist of roll damping system to meet particularly important stabilization criteria which can also satisfy hydro-dynamically control in many loading and weather condition. Seakeeping characteristics of the fishing vessels need compensation of motions even at low or zero speeds because of operation areas in high sea-states.
Roll damping tanks define as also anti-roll tanks can be divided into two main categories as free surface solution which is simple rectangular containers with central obstruction to impede the flow waters and U-tube solution consists of two separate tanks connected by a water conduit at the base and optional air channel in the roof, with valves in the flume to adjust the fluid flow. While some design companies can create its own shapes to implement the vessel, some companies specialize in the system design and control arrangements.
Regenerate power is the latest trend in the newbuilding segment. Furthermore, new solutions are releasing to the market to increase efficiency and energy recovery. When a system has common usage in a vessel type, improving the current solution and make a new opportunity can be a more efficient way. That’s why a new technology to have regenerated power from roll motions in reduction tanks may be a new trend in this segment. This new technology, free unlimited power, was released by GEPS Techo and to be implemented in our new innovative and eco-friendly vessel NB64 LIBAS with each 30 kW two turbines as the stabilizer with the recovery of energy.
Because of free power, roll reduction devices investments return on in a certain period to the client. Our expectation from the future, this type of solutions to be more common and reduce the initial cost in this way.
Electrical or hydraulic is one of the key questions while selecting winch solution in the fishing vessel..
