Duties After Pilot
Departure
After the ship is out of
the port limits and the pilot has gone, the marine engineers have a lot of work
to do - from adjusting the main engine revolutions to run at maximum possible
load as per the weather to starting the fresh water generator, etc. The
complete plant has to be set up to run optimally.
Pilot on Board: What it
Means
When cargo operations
have been completed and port clearance has been given for leaving, a one-hour
notice is given to the engine room and duty engineer. At the receipt of the one
hour notice, the engine room is manned and an additional generator is started.
Thereafter as per the checklist, the Main Engine plant is made ready by the
duty engineers.
Once the main engine has
been lubricated and turned by the turning gears and blown though with air, the
engine control is given to the bridge and they are told to try out the engine.
Before the arrival of the
pilot is expected, the control tests, the steering gear tests, communications
tests, and the main engine is tried out in ahead and after directions on
fuel.The same is written down in the engine movement records book and signed.
When the pilot arrives on
board, the order of "Stand By" is given. This order literally means
stand by as the engine control room and the main engine controls have to be
attended by an engineer at all times during maneuvering. This is because engine
movement can be expected at any moment. Even though the engine is on bridge
control, for failsafe operations the engineer must be present. At any misfire
or problem, the engineer will take control in the engine room and give the
movement.
At the stand by time the following readings are
recorded in the bell book to enable the Chief Engineer to calculate the ROB's
of fuel and lubes.
·
Main engine revolution counter
·
Flowmeters for Main Engine, Generators, and Boilers
·
Flow meter for cylinder oil
In modern ships the HFO purifier is always
running as all systems are on heavy oil; if not then the HFO and Diesel Oil
purifier (on older ships) has to be started.
During maneuvering the movements are
recorded by the data logger in the bridge and movements are only to be written
in the engine bell book if main engine is in engine room control.
Maneuvering is a very critical operation,
and strict control and team work is required by all crew to carry it out
successfully. As engine room people are not aware of what is happening above
the water level, good and sufficient communication by the bridge team is always
appreciated.
Pilot Away!
After the ship is out of the port limits
and safely in the open sea, the pilot departs. After "Pilot Away" has
been informed the main engine rpm is increased to navigational full and RFA of
full away is given on the engine telegraph. Full away indicates that no more
engine movements are expected in normal circumstances and the main engine can
be adjusted for optimal efficiency. The additional generator can be shut and
normal work can be carried out.
Another set of counters and flow meters
must be taken at this moment to enable the chief to do his calculations.
After starting the fresh water generator,
the main engine can be adjusted to maximum revs. The exhaust boiler is then
taken in service and the oil fired boiler put in auto stop.
If the auxiliary engines were being cooled
by auxiliary sea water pumps, then they are changed over to main cooling sea
water pumps.
All safeties tested, and Chief Engineer goes up to his office to
do his paper work and reporting.
