TECHNICAL SPECIFICATION DOCUMENT STABILIZER HULL UNIT DESCRIPTION: A stabilizer hull unit is the energy transfer device in Quantum’s fin stabilizer systems. The hull unit is installed in the turn of the bilge with its main shaft penetrating through the vessel’s hull to connect to the stabilizer fin. It uses hydraulic cylinders to rotate the main shaft, which in turn, deflects the fin to reduce roll. Designed using the latest technology and high-quality materials, the QC1500 is a rugged machine that is capable of significantly reducing vessel roll during both underway and Zero SpeedTM operations. FEATURES: SIMPLE INSTALLATION: The hull unit is delivered fully assembled for easy installation into the vessel’s structure, via the supplied welding bushing. PRECISE FITS AND CLEARANCES: The main shaft features a tapered cut for true stabilizer fin connection, and a rotating-spline connection to the tiller and hydraulic cylinders. These precise fits promote a smooth transfer of energy from the hydraulic cylinders to the stabilizer fin. SAFETY PRECAUTIONS: Heavy-duty bolts are used to manually return the fin to its center position in the event of an emergency. LOAD HANDLING: A series of sleeve bearings and a spherical roller bearing distribute the motions and loads imposed on the hull unit. MINIMAL MAINTENANCE: The hull unit is simple to maintain during normal operation, with stainless steel components used extensively to minimize corrosion. Easily accessible grease nipples are built-in with internal porting for regular greasing of the bearings. The unit is designed for replacement of o-rings, seals, and bearings during vessel haul-outs every other year.
