Engineers Bell Book
The engineers bell book is a chronological
record of orders pertaining to the speed of the
engines. The book contains a record of orders
affecting each shaft. It shows the time of receipt
of each order to change the propeller speed, the
meaning of the order, and the revolutions per
minute resulting from action taken in obedience
to that order.
The structure of our shipboard organization
allows ships to operate safely and effectively.
Seldom do ships operate in exactly the same
manner, but all classes of ships have the same
basic organization. As new ships and new
technologies are developed, our organizational
structure will be adjusted to operate them
One thing that will never change, however, is
the chain of command. Someone will always be
ultimately responsible for the operation of the
ship: the commanding officer. Likewise, someone
will always be assigned to assist the commanding
officer: the executive officer. Department heads
and division officers will also be assigned areas
While names and titles may change, the
function of the chain of command will remain the
same on naval ships. It will continue to ensure
organization aboard the ship, which contributes
to the accomplishment of its mission.
