CRP/CPP SYSTEMS OPERATIONS
In this section, we will briefly cover routine and
emergency operations of the CRP/CPP systems. Since
the various ship systems are functionally the same, we
will not indicate ship type except when necessary.
However, if you need to review the basic design and
operational characteristics of these systems, consult
GSE3/GSM3, volumes 1 and 2.
Propeller pitch changes can be made through the full
range of travel in one continuous movement. The pitch
change can be made in automatic, remote manual, or
pitch change, 30 seconds from full ahead to full astern,
is determined by the response of the hydraulic system.
Pitch change rate is NOT determined by the speed of
movement of the control lever.
The CRP/CPP systems were designed to maximize
the ability of the ships propulsion GTE to accelerate
and decelerate rapidly and to enhance maneuverability.
To further enhance the systems performance and to
make them more user friendly, some subtle changes
were made. These changes have been installed on the
newest gas turbine ship platform, the DDG-51 class
ship. The following sections will explain some of these
changes and the contributions they make to system
As a GS supervisor, you should be aware of the
changes incorporated in the CRP/CPP systems installed
on the DDG-51 class ships and the advantages they offer
