MariFlex P.U.M.P.S.® (Portable Ultra-viscous Marine-fuel Pumping System)
De-bunkering & Salvage operations in cold climate conditions with Heavy Fuel Oil (HFO) reaching ultra-high viscosities, present the ultimate challenge for all existing fuel oil transfer methods.
Where accessibility is difficult and conditions are extreme MariFlex is frequently contracted to provide a solution for the transfer challenges faced.
Continuous R & D within the MariFlex Group led to various pumping solutions with amongst others MariFlex P.U.M.P.S.® (Portable Ultra-viscous Marine-fuel Pumping System).
This system incorporates an improved modular version of the proven water injection transfer method coupled to the existing MariFlex F.O.T. (Fuel Oil Transfer) system.
Specifications: MariFlex P.U.M.P.S. ®
– Water input fraction of <4%
– Pressure build up drops from 12 bar to 1.4 bar, pressure drop reduction of >95%!
– Test results show flow rate improvement up to >35 m3 an hour with HFO-380 @ 20 °C (4000 cSt)
– Viscosities up to 50,000 cSt
– Pipe lengths up to 1 kilometer
– Customized solutions
Tests in a real transfer system confirmed the designer’s very promising theory and the system gained operational status. The graph below shows thedifference between P.U.M.P.S.® and a
conventional F.O.T. system.
The green line represents the pressure drop (bar/m) during transfer of HFO-380 @ 20°C (4000 cSt) with the F.O.T. system through 200 m of 4-inch hose with a maximum safe working pressure of 12 bar.
This leads to a flow rate of 13 m3 an hour. The light blue line however represents the pressure drop (bar/m) during transfer of the same utilizing P.U.M.P.S.® This leads to a flow rate of 35 m3 an hour with a pressure drop of only 1.4 bar. A pressure drop reduction of more than 95% is obtained!
