Ship Systems & Power

The floating city. Pumps, generators and the ship's electrical plant, piping systems, fresh water, ballast and automation.

• Pumps — Pumps add energy to liquids. Learn centrifugal vs positive-displacement pumps, head, flow and hydraulic power, pump and system curves, efficiency, affinity laws, NPSH and cavitation, and series/parallel operation.
• Generators — Generators turn mechanical energy into electricity. Learn the alternator EMF equation, frequency–speed relationship, excitation and AVRs, governor droop and load sharing, and the conditions for synchronising to the grid.
• Ship Auxiliary Systems & Electrical Power — Everything that keeps a ship alive besides propulsion. Learn electrical power generation and load analysis, switchboards, emergency power, shaft generators and diesel-electric plants, pumps and piping systems (bilge, ballast, fire, fuel, lube), ballast-water treatment, fresh-water generation, HVAC and refrigeration, sewage and oily-water separation, steering gear, compressed air, and automation/alarm systems — with Python for load balance, generator sizing and fresh-water production.
