Results from Navy Region
Northwest CTMA/JTEG Regional
Workshop
The 100+ participants in our 3rd CTMA regional
workshop held in Bremerton, Washington developed 21 possible CTMA
project ideas as a result of the 2-day workshop. Below is a quick
description, along with the person responsible for entering the idea
more fully on the CTMA ideas website,
http://ctmaideas.ncms.org.
Projects will be entered on the ideas website by Thanksgiving, which
will be available to all others interested in learning further
details and possible participation.
-
Portable Water Filtration System (Randy
Baisden,
PSNS)
-
Contaminants
cannot
be
directly
disposed
to
water
system.
-
Hydro
blasting
(closed/open)
cycle.
Copper
content
is a
problem.
-
Washing
the
exterior
hull,
tanks
(MBTs),
heat
exchangers,
dry-dock
floors
are
problem
areas.
-
Containments (Bob Vozzela, PNS)
-
Current
containments
are
single
use,
with
a
lot
of
pre-build,
tear
down
time
averaging 30,000
man-hours
per
structure.
Containments
could
be
made
from
air
structures,
rather
than
current
structural
members
and
(staging)
shrink
wrap.
-
Mold-In-Place (MIP) SHT
(Alan
Orr,
PSNS)
-
There
is
no
procedure
for
removing
Mold-In-Place
(MIP),
from
composites
other
than
with
hand
tools.
-
Development
of a
procedure
is
necessary,
using
methods
such
as
the
3M
Smart
tool.
-
MIP/SHT Removal from Hull (Maxie
McCowan,
PSNS)
-
Costly
and
difficult
to
precisely
remove
MIP.
Possible
solutions
may
be
water
jet
blasting
with
abrasive,
laser
coating
removal,
or
cryogenic
freezing.
-
Damping
Tile
Removal
(Maxie
McCowan,
PSNS and
Max
Shinkawa,
PHNSY)
-
Breaking
adhesive
bonds
is
difficult,
and
can
cause
damage
to
hull,
which
then
require
welding
repair.
Chipping
guns
can
also
cause
ergonomic
injury.
-
Induction
heating
is a
possible
solution.
-
MIP/SHT Replacement Tile Installation (Adhesion)
(Alan
Orr,
PSNS)
-
Expensive
environmental
controls
are
required
to
successfully
apply
tiles.
The
current
21-day
flow-time
(blast,
paint,
QA)
is
too
long.
-
What
is
needed
is a
faster
setting
adhesive
which
is
not
sensitive
to
temperature
and
humidity
levels.
-
Develop Sampling and Inspection Software System
(Dan
Craig,
PSNS)
-
The
existing
database
is
going
away
(MS
Access),
and
data
cannot
be
shared
between
the
shipyards.
So
sampling
inspection
can
be
done
multiple
times.
-
The
project
would
develop
an
automated
sampling
and
inspection
system
that
can
be
used
and
shared
by
all
the
shipyards.
-
Paint
Hose
Temperature
Control
(Randy
Baisden,
PSNS)
-
Electrically
heated
hose
is
not
currently
safe,
and
must
meet
NFPA
Class
1,
Division
1
(explosion
proof),
and
8,000
psi
requirements.
-
Design
paint
hose
that
maintains
temperature
tolerances
for
correctly
maintaining
paint
viscosity.
-
Non-Skid removal on MIP/SHT
(Randy
Baisden,
PSNS)
-
Procedures
need
to
be
developed
to
remove
non-skid
without
damaging
MIP/SHT.
No
solutions
currently
exist.
-
Portable Laser Crawler to Remove Coatings
(Randy
Baisden,
PSNS)
-
Expensive
to
dispose
of
processed
waste
and
hazardous
materials.
-
Develop
a
portable
laser
crawler
system
to
remove
coatings.
-
Replace Radiographic Weld Inspection for Volumetric
Inspection
of
Shipboard
Piping
(Rob Gorman, PSNS)
-
TP-278
requires
RT
as
the
only
method
for
volumetric
inspection
of
critical
piping,
pressure
vessel
and
machinery
welds.
RT
is
too
cumbersome
and
expensive
shipboard,
as
outlined
by
Rob
Gorman’s
presentation.
Problems
are
crew
size,
disruption
of
other
work
(impact
on
schedule),
speed
of
inspection
and
radiological
safety.
-
Currently
5 up
to
30
man
days
required
for
a
single
weld
joint
inspection
(not
including
interpretation).
-
Implement
Phased
Array
(PA)
ultrasonic
inspection
of
welds.
The
solution
needs
to
be
applicable
to
shipboard
piping
sizes
and
material.
-
Submarine
Battery
Layout
and
Placement
(Mark
Kougl,
PSNS)
-
Current
template-based
layout
and
placement
methods
for
hold
down
rails
are
subject
to
excessive
tolerance
mismatch
and
accumulation,
variation
in
as-built
configuration
of
battery
compartments,
and
excessive
time.
Layout
and
placement
of
studs
have
similar
issues.
Welding
of
rails
introduces
distortion.
-
A
possible
solution
for
development
is a
new
process
using
laser-based
3D
metrology
of
as-built
space;
CAD
modeling;
optical
layout
aids;
and
real-time
laser
based
aid
to
maintain
dimensional
tolerances
during
welding.
-
Cleaner Ripout
(Mark
Kougl,
PSNS)
-
Current
techniques
require
excessive
handwork
and
high
likelihood
of
damage
to
structure
requiring
rework.
-
The
project
would
develop
cleaner
methods
of
cutting
steel
in
tight
configurations
and
subject
to
temperature
and
environmental
constraints.
-
Low Heat Input Welding Techniques
(Mark
Kougl,
PSNS)
-
Current
welding
techniques
induce
distortions
in
parts
and
cause
potential
excessive
heat
input
resulting
in
unacceptable
effects
on
coatings
and
adjacent
lead
bins,
with
excessive
process
time
required
to
stay
within
limits.
Problem
will
become
more
severe
in
future
scheduled
refits
with
thinner
steel
material.
-
The
project
would
investigate
alternative
welding
technologies
for
performance
and
adaptability
to
battery
room
conditions.
-
Remote
Monitoring
of
Equipment
and
Processes
(Dana
Ellis,
Epsilon
System
Solutions,
Inc.)
-
Currently
there
are
no
low
cost
means
to
monitor
remote
equipment
–
HPAC’s
etc.
-
The
project
would
develop
secure
wireless
and
software
that
monitors
and
analyzes
operational
parameters
of
various
equipment,
i.e.,
lube
oil
pressure,
bearing
temperature,
discharge
pressure,
etc.
Once
a
low
or
high
condition
is
met,
output
is
linked
to a
repair
recommendation
or
condition-based
maintenance.
-
Material
Management
Container
Location
&
Movement
Tracking
(Don
Adams,
I.D.
Systems,
Inc.)
-
It
is
difficult
tracking
containers
moved
by
vehicles.
-
The
project
would
build
off
the
current
CTMA
project,
CFAMS,
to
integrate
and
record
RFID
tag
and
reader
to
confirm
what
has
been
moved
when,
where
and
by
whom.
-
Point
Cloud to
CAD File
Translation
Tool
(Kyle
Morris,
NUWC
Keyport)
-
The
current
data
translation
process
is
very
labor
intensive.
-
The
project
would
reduce
reverse
engineering
lead
time
and
associated
cost
by
developing
a
software
system.
-
Machined
Parts/Knowledge
Management
(Tom
McClure
TechSoLVE,
Allen
Carrier
PSNS)
-
Lead
time
for
critical
spares
is
unacceptable,
and
there
are
limited
sources
of
suppliers
able
to
provide
short
runs/prototyping.
-
Lack
of
corporate
wide
knowledge
of
existing
DoD
or
Vendor
suppliers.
-
The
project
would
develop:
i.
Improved SW
tools to
reduce NC
programming,
ii.
Establish a
DoD/Vendor
knowledge
management
tool,
iii.
Supplier
Capabilities
Database
(DoD/Vendor)
-
Condition
Monitoring
of
Temporary
Services
Assets
(Peter
Sisa,
RLW,
Inc.)
-
Currently
reactive
response
–
run
to
failure
maintenance
of
high
value
equipment
for
temperature
services.
-
The
project
would
demonstrate/implement
condition
monitoring
capability
for
Shop
99
selected
key
assets.
This
capability
should
integrate
with
eFem
and
trigger
standard
work
orders
and
parts
ordering.
-
Maintenance
and
Repair
Associated
Funding
Strategy
Plan
(Paula
Kramer,
Tooele
Army
Depot)
-
Funding
for
maintenance
and
repair
is a
problem.
i.
No-one in
maintenance
writes SBIR
topics for
maintenance
issues.
ii.
No
SPONSORSHIP
(no 6.x or
7.x series)
iii.
Looking at a
budget
series
number
“Maintenance”
is What is
the DoD
funding pot?
iv.
Lack
of Contracts
vehicle.
-
The
project
would
develop
a
technology
trajectory
for
maintenance
and
repair
generic
topics.
i.
“Top
5” drives
coordination
between
04X’s of
DoD, R&D and
Funding
Decision
Makers.
ii.
Contract
Vehicles put
in place.
-
Central
Repository
for PLM
i.e. CAD
drawings
etc.
(Kyle
Morris,
NUWC
Keyport)
-
CAD
data
is
managed
locally
within
different
DoD
facilities.
-
The
project
would
develop
a
secure,
digital,
on-line
system,
a
“JDMICS
on
steroids”

Polymeric composite materials are seeing
increasing usage in weapon systems due to their superior
weight/performance advantages and resistance to corrosion.
However, repair equipment and processes for composite materials
are only now being developed to address the increasing workload
coming into the DoD maintenance and repair facilities. This
project is focusing upon C-130 Radomes, F-15 Radomes and F-15
Speed Brakes, which are large complex structures, with a high
volume repair rates. The current Radome, and other composite
component, inspection and repair processes are performed
manually by artisans. This project is developing technology to
replace these manual methods with automated systems. The first
phase of this program will be devoted to qualifying individual
processes on a stand alone basis, but performing the function of
each technology using the targeted components to qualify the
technologies. Upon success, a phase will be utilized for
performing the functions required, employing the individual
processes in the machine tool/work environment and constraints.
These technologies will also be applicable to the other services
repairing composites parts. However, the current focus of this
project will be on Air Force Radomes where the benefits can be
quickly realized.
