Thats why close scrutiny of their
operating and treatment records is so important. The
importance of maintaining accurate WHB operating
records, boiler water and feedwater chemistry logs and
records must not be underestimated. The engineer
officer and assistants use the data in these records to
measure the performance, stability, efficiency, and state
of material readiness of the engineering plant.
Remember, the decision-making process involved in
effective WHB operations and the water chemistry
program aboard your ship is supported by the
information contained in these records. To be an
effective engineer and supervisor, you should be
familiar with the purpose, content, and general
procedures to properly review and train your personnel
to maintain each of these records.
UPDATE WHB OPERATING RECORDS
WHB operating records information is derived and
compiled from several different logs and inspection
Basic boiler information is recorded in the
engineering log as events occur. These events normally
include start-ups, shutdowns, and blowdowns.
However, the primary log where the majority of
information is compiled is the WHB Boiler Water
Chemistry Worksheet/Log. This log is updated as
events occur and is closed out on a daily basis.
Basically, all maintenance performed on the boiler and
its operating systems, chemical treatments, and
operating hours are entered in either the Remarks
section or the Boiler Data section on the backside of the
WHB Boiler Water Chemistry Worksheet/Log.
The last source of boiler status information that we
will discuss is the Boiler Inspection and Repair
Management Information System (BIRMIS) report.
This systems purpose is to enhance the value of
auxiliary boiler inspections. The BIRMIS report
contains useful information concerning the health of
your WHB. This report is filled out by the boiler
inspector at the completion of any standard or emergent
boiler inspection. As a supervisor you must understand
the information provided in this report so you can
effectively plan (schedule) and correct the listed
discrepancies. In figure 1-10 of this next section, there
is a sample of a BIRMIS report. This sample report
should help you identify and understand the information
As you can see, the BIRMIS report is broken down
into three distinct sections.
This sample report is
representative of the inspection of the No. 3 WHB. The
first section is the cover sheet and some standard
information that you provide to the inspector. The
second section is for inspector comments. In this
sample, the inspector chose to provide a list of
references that would be used as guidelines to perform
the inspection. The third section contains (from left to
right) the item (component) inspected, the number of
d i s c r e p a n c i e s n o t e d ( e n t r y c o n d i t i o n ) , t h e
recommended repair, and the deficiency status code.
For clarification and standardization, the BIRMIS
system uses set codes to identify each boiler component
and subcomponents being inspected. As in the sample
form, the C represents the boiler tubes (primary), and
the Cl and Cll represent specific sections of the tubes.
And finally, the entry condition is the sequential listing
of each discrepancy found for that component.
UPDATE WHB WATER TREATMENT
As a GS supervisor you must become more familiar
with updating and reviewing WHB water treatment
records. Depending on your assignment within the
engineering department and if your ship has boilers, you
will be tasked either daily or intermittently with
updating and reviewing these records. In the remainder
of this section you will find two basic check sheets (figs.
1-11 and 1-12) that you can use to properly review the
WHB water treatment records. These check sheets are
not mandatory, but the information is very helpful. This
information was taken directly from an NSTM and the
numbers listed at the end of each question should be a
help to you.
In this chapter we have discussed various programs,
reports, and records needed by GS supervisors. The
titles of the different sections of this chapter may sound
like many of those presented in some engineering
administration publications. Even though the topics are
in other publications, the information in this chapter is
specific togas turbine-powered ships. Throughout this
chapter you have been referred to the EOSS, applicable
technical manuals, or the PMS for specific information.
You must use these references to guide you through the
procedures. Use of the EOSS, technical manuals, and
the PMS will help you make the proper decisions to best
handle the duties of a GS supervisor.
