BECC Test 5 2026/2027 Questions & Answers | Pumps, MRG, Lube Oil, Hydraulics, Steering Gear, OWS & Shipboard Engineering

This 23-page BECC Test 5 2026/2027 exam study guide provides an extensive collection of questions and answers focused on shipboard engineering systems, machinery operation, maintenance, fluid systems and auxiliary equipment. The material covers centrifugal and rotary pumps, oily-water separation, heat exchangers, gears, couplings, bearings, main reduction gears (MRG), propulsion shafting, tanks, ballast systems, piping, refrigeration, lubricating-oil quality management, cooling-water systems, compressed air, reverse osmosis, hydraulics, steering gear, conveyors, anchor windlasses and lubricating-oil purification. The opening sections provide detailed review of pumps and fluid-handling equipment. Questions examine centrifugal-pump operation, impellers, check valves, recirculation lines, pump cavitation, rotary gear pumps and pump wear protection. The document then addresses the Oily Water Separator (OWS) system, including oily-waste holding tanks, duplex strainers, waste-oil tanks, oil-content monitoring and the stated 15 PPM discharge limit. Heat-transfer material covers conduction, convection, condensers, plate-type and double-tube heat exchangers, helical/spiral arrangements, and parallel and cross-flow configurations. A substantial section focuses on gears, bearings, couplings and main propulsion machinery. Students review spur, internal spur, helical and double-helical gears, torque, idler gears, flange and flexible couplings, needle and journal bearings, anti-friction bearings, resistance temperature detectors and friction. Main propulsion questions address line-shaft and strut bearings, the Kingsbury thrust bearing, bulkhead seals, propulsion shafting, MRG lubrication, dehumidification and routine bearing monitoring. The guide also examines shipboard tanks, ballast, piping and auxiliary systems. Covered concepts include potable-water tanks, VCHT systems, seawater-compensated fuel-storage tanks, feedwater, baffles, sounding tapes, tank vents, sight glasses, draft, ballast and deballast operations, flexible hose assemblies, hydrostatic testing, unions and spring hangers. Refrigeration and air-conditioning questions review refrigerants, receiver relief pressure, temperature control, chill-room operation and refrigerant-flow components. Another major study area is lubricating oil and LOQM/JOAP procedures. The material covers 2190 TEP and 23699 oils, MRG and line-shaft-bearing oil inspections, bright-and-clear sample characteristics, BS&W testing, sample connections, centrifuge operation, flash-point testing, oil-purifier efficiency, batch renovation, settling tanks and oil-analysis responsibilities. Later questions examine purifier components and operation, including bowl-locking screws, purifier disks, worm-wheel drives, water seals, regulating tubes and the operating values provided in the source. The final sections provide concentrated review of auxiliary machinery and control systems, including AMCW, auxiliary seawater, low- and high-pressure compressed air, dehydrators, intercoolers, reverse-osmosis water production, Pascal's law, hydraulic actuators, unloading valves, strainers, hydraulic fluids, viscosity, steering gear and axial-piston pumps. The document concludes with vertical package conveyors, anchor windlasses, wildcats, capstans, brakes, gearboxes and associated operating terminology such as paying out and heaving in. Relevant students: This document is particularly relevant to students and trainees studying BECC, basic shipboard engineering, naval engineering fundamentals, marine engineering, propulsion and auxiliary machinery, machinery maintenance, and shipboard mechanical systems. It is also useful for learners reviewing pumps, fluid systems, MRG and shafting, LOQM/JOAP, hydraulics, steering equipment, compressed air, OWS, refrigeration and other engineering-system terminology represented in the exam material. Course code and university: The uploaded document identifies the assessment only as “Becc Test 5” and does not provide a separate academic course code, university or college name. No institution has therefore been added to the title without documentary support.
