MMA Method
In order to satisfy NVIC 17-14 Task 6.1.D , MMA students must:
- Successfully complete MMA Assessment OICEW-7-1E Parallel generators
- Successfully complete MMA Assessment OICEW-7-1D Connect ship service diesel generator to main switchboard

OICEW-B1.1 Basic configuration and operation principles of the following electrical, electronic and control equipment
Preparing, starting, paralleling and changing over generators
|
| Condition | Behavior | Standard |
|---|
|
On a vessel of at least 1,000 HP, on a simulator, or in a laboratory,
|
the candidate plans for and connects the ship’s service generator to the main switchboard, and takes original on-line unit off the board.
All
The assessment is required for all OICEW endorsements regardless of any limitations for propulsion mode and/or vessel equipment.
|
The candidate takes the following actions, describing them as they are performed:
Ensures the plan reflects proper sequence of actions, is complete, and conforms to the requirements of manufacturer’s instructions and ship’s procedures; Pre-inspects and starts the generator prime mover; Verifies that automatic voltage regulator is at recommended voltage and manually adjusts as necessary; Turns on synchroscope and observes direction and speed of rotation; Manually adjusts generator speed so that the scope rotation is moving slowly in the “fast” direction; Manually closes the in-coming unit’s circuit breaker to stop the synchroscope at the 12 o’clock position; turns off scope; Divides load simultaneously and evenly between on-line and in-coming units by observing available switchboard meters; Continues to shift load between unit to remain on-line and off- going unit, observing available switchboard meters; Continues to manually reduce the off-going unit load until off- going unit circuit breaker trips, or trips breaker manually as the kW load of off-going unit approaches 0; and Takes proper action to prevent safety and pollution violations.
