High power generation is required on ships for cruise lines, tugs, tankers, and dredgers.
The generator rating depends to a large degree on a fairly close assessment of peak power and the relative timing of each load.
Various electrical loads in merchant ships generally fall in the following
groups:
- (1) propulsion machinery
- (2) auxiliary machinery
- (3) cargo-handling machinery
- (4) deck machinery
- (5) HVAC equipment
- (6) control electronics
- (7) communication electronics
- (8) shop load
- (9) hotel loads
Each individual load in these groups may draw different kW power during different phases of the ship operation.
