This study presents the design and optimization of an electronic remote-controlled Platform Supply Vessel (Rex Maris), integrating systematic hull optimization with unmanned propulsion control. Principal dimensions were determined via regression analysis of reference vessels; four hull variants were evaluated using Maxsurf hydrodynamic simulation to minimize resistance. The selected monohull design achieved 15% resistance reduction (total resistance = 14.73 N at design speed Vs = 10 m/s) yielding Effective Horsepower of 147.3 W. Comprehensive propulsion calculations incorporating hull efficiency (ηH = 0.67), propeller efficiency (ηo = 0.35), and relative rotative efficiency (ηrr = 1.0) yielded propulsive coefficient Cp = 0.23 and overall propulsive efficiency of 0.67 - 0.70, exceeding conventional PSV benchmarks (0.55–0.65). Energy analysis indicates 8% fuel consumption reduction while maintaining full remote control operability via 7-channel 2.4 GHz wireless system. Results demonstrate that integration of remote control technology does not impose propulsive penalties when coupled with hull optimization, addressing the research gap in electronic remote-controlled support vessels for Indonesian offshore operations.
