UNDERWAY REPLENISHMENT
LEARNING OBJECTIVES: Explain
procedures for day and night underway
replenishment (UNREP). List ships involved.
Explain the use of flag signals, transfer station
markers, distance line marker, emergency
breakaway, and communications alongside.
Another part of your duties as a Signalman is to
be able to communicate effectively during night and
day UNREP. To be able to communicate during
replenishment, you first must understand what
Figure 8-5.—Day and night storm-warning signals.
UNREP is all about. This section defines UNREP,
including the ships involved and the day and night
signals used to communicate.
Underway replenishment is a broad term applied
to all methods of transferring fuel, munitions,
supplies, and personnel from one vessel to another
while under way.
SHIPS INVOLVED
There are usually two ships involved in an
UNREP. One serves as the control and delivery ship,
the other as the approach and receiving ship.
Control Ship
The control ship is normally the ship delivering
the product. She maintains replenishment course and
speed and normally serves as the guide.
