The Navy’s policy is, all activities having custody
of marine gas turbine equipment, that is, single-shaft
engine assemblies or modular engine assemblies (major
sections of the engine that are replaceable), associated
components, accessories, and ancillary equipment, must
maintain service records in a proper and up-to-date
status.
REVIEW MGTE LOG BOOKS (MGTEL)
A periodic review of the MGTEL should be done
and as a GS supervisor you may be tasked with this job.
In the Gas Turbine Systems Technician (Mechanical) 2
and Gas Turbine Systems Technician (Electrical) 2
training manuals you were told the MGTEL is a
hardcover book that houses all the marine gas turbine
equipment service records (MGTESRs). You were also
given a basic description of each record sheet and the
type of information found on each sheet that makes up
the various sections of the MGTEL.
In addition to the information provided in the rate
training manuals and NSTM, chapter 234, you can use
this sample checklist to follow when you conduct a
review of your logbooks. The numbers listed at the end
of each statement or question are reference paragraphs
from NSTM, chapter 234.

UPDATE MGTE SERVICE AND
OPERATING RECORDS
Updating MGTE service and operating records is
normally performed by the log custodian. The log
custodian is usually the main propulsion assistant
(MPA). Even though the MPA is the log custodian, you
may still be tasked to make updates to the logs. In any
case, if you follow the guide provided in the next section
you will know what entries are required and the proper
way to make the update.
WHB OPERATING AND TREATMENT
RECORDS
Even though the WHBs installed on your ship are
considered auxiliary equipment, they play a very
important role in the ship’s ability to remain
