Condition | Behavior | Standard |
On a steam vessel of at least 1,000 HP, on simulator, or in a laboratory,
|
the candidate assists in starting a main propulsion turbine engine, describing the actions as they are being performed.
|
The candidate:
-
Starts the main lube-oil pump;
-
Verifies that there is flow through the gravity tank overflow line using the sight-glass;
-
Verifies that there is lube-oil flow to all main-engine bearings;
-
Engages the jacking gear to the main engine;
-
Makes notification of jacking gear status;
-
Turns on jacking-gear motor;
-
Establishes steam flow to the gland-seal regulator and adjusts it to recommended levels;
-
Starts the gland exhaust condenser fan;
-
Verifies that the main circulator high-suction and overboard-discharge valves are open;
-
Starts the main circulator pump;
-
Opens the main-condenser saltwater header vents until flow is observed;
-
Verifies that main condensate pump suction and discharge stop valves are open;
-
Verifies that main condensate pump vent line valve is open
-
Starts the main condensate pump;
-
Opens the inlet/outlet valves to both the first and second stage air-ejector elements;
-
Lines up steam to the air-ejector pressure reducing station;
-
Opens the steam root valve to the second stage main air- ejector element;
-
Observes progressive increase in vacuum;
-
Inspects the entire system for proper operation;
-
Correctly describes actions as they are being performed; and
-
Takes proper action to prevent safety and pollution violations.
