was so effective that we use it in our design office to
this day.
3) A Master Drawing List & Schedule. Every drawing
delivered by every engineering entity was tracked in
a single spreadsheet, which proved to be invaluable.
In the end, there were over 3,000 drawings listed,
most with several sheets! Maintaining this list was a
full time job for the project’s document-control per-
son, and we turned to it daily as a management re-
source.
Can we say that a Word docu-
ment task list and an Excel
spreadsheet were the tools for
managing this vast engineering
enterprise? Yes, we can, but
nothing works without everyone
buying in to the tools and using
them in their daily work.
3. Involve Class and Flag in your
design process.
When the decision is made to
build a vessel to the standards of
a classification society or a flag
state, it is just as important to
make the decision to involve
both parties in the design and
engineering process. There are
endless examples we can point
to both in this project and others
where a surveyor is surprised by something they see on the
vessel.
Simply put, do whatever you can to avoid this type of situa-
tion! It can be as easy as sending class and flag concepts,
and getting their feedback. Remember, it is their job to sign
off on the project and verify it is built to standards. If you
make their job easier, everything seems to run a little mo
smoothly.
4. Involve test procedures & criteria in your drawings.
The launch of any vessel invariably includes a battery of
tests to be performed, both for quality assurance and fla
class compliance. Most yards, including Derecktor, have
in-house team that is dedicated to this cause, which begi
the first time metal is welded, and concludes with the fin
sign offs.
This quality team often strug-
gled with the simplest of que
tions, and would often not kn
the basis by which to verify q
ity. This team often worked fr
the engineering drawings, wh
invariably did not contain the
data that would answer thes
types of questions: “What is t
required flow rate of this sys-
tem?” “What is the safe work
load of this winch?” “How fas
should this life raft deploy?”
In the end, we as naval archi-
tects and designers work to
standards and make assump
tions on loads and material
properties. Put this informati
on your drawings, and that will make sure that the desig
targets are built, and tested properly.
5. Failure Modes and Effects Analysis (FMEA)
Just before Christmas 2009, Tom Derecktor, then Presid
of Derecktor Shipyards, gathered all of engineering and p
duction together and launched the Failure Modes and Ef-
