Oil spill incidents create serious risks for marine ecosystems, coastal infrastructure, industrial operations, and environmental safety. In emergency oil spill response, containment booms must be deployed and retrieved quickly to restrict the spread of floating oil. Manual boom handling is slow, unsafe, and difficult, especially when the boom becomes waterlogged or exposed to wave and current action. This paper presents the design and development of a hydraulic powerpack-driven boom reel systemfor oil spill containmentapplications. The proposed system is intended to handle a 3.5-ton operational load, operate at a controlled reel speed closeto7RPM,andsupport high-torque boom retrieval under industrial working conditions. The system consists of a heavy-duty boomreel frame, rotatingdrum, support structure, shaft, bearings, hydraulic motor, gearbox, diesel engine-driven hydraulic powerpack, flowcontrolvalve,pressure control elements, filtration unit, and safety components. The design was developed using mechanical designprinciples,3Dmodelling, frame design, hydraulic circuit planning, and preliminary Fusion 360 structural simulation. The hydraulic drivecalculationwas performed for an OMSU 200 hydraulic motor, 15 LPM available flow, 215 bar pressure, and 6.1:1 gearboxreduction.Thecalculation showed an estimated motor torque of 122 Nm at 15 LPM, output speed of 12.17 RPM with one gearbox, and6.14RPMwhenthe flow is divided between two gear motors. The calculated gearbox output torque was approximately 744.2 Nm, indicatingthatfurtherdrivetrain optimization is required to fully satisfy the 2700 Nm target torque. The preliminary cost estimation of the boomreel wasfoundto be approximately ₹1,80,000 to ₹2,50,000. The study demonstrates that a hydraulic powerpack-driven boomreel canreducemanualeffort, improve operational safety, ensure controlled boom handling, and provide a practical foundation for industrial oil spill responseequipment.
