Need / Objective
• The Navy needs a mechanism to cost effectively
either extend the shelf life of MILSPEC compliant
paints that are currently used aboard Navy
vessels or look to process improvements and/or
technologies for solutions that results in a
reduction of paints ending up as HW.
• Determine the merit and feasibility of establishing
a process for identifying how and when paints
can be recovered and reprocessed by
manufacturers.
Findings / Recommendation
• The amount of unused paint from ships disposed
of as waste has already been reduced through
various processes.
• Few manufacturers will take waste paint and will
not take from other manufacturers. They also
want a predictable waste stream.
• Due to the above findings, establishing a program
to return expired paints to manufacturers is not
recommended.
Benefits & Capabilities
• Avoid Excessive Disposal Costs and
Waste.

Dynamic Mixing Zone Modeling
Sponsor: NESDI/PSNS NESDI Project #473
Problem: Discharges from Navy facilities must have permits
under the National Pollution Discharge Elimination System
(NPDES) program. Discharge limits imposed by states and/or
the U.S. Environmental Protection Agency (EPA) require all
discharges to meet water quality standards at the end of the
pipe unless a mixing zone is granted within the permitting
process. Existing data collection/models can not address the
unique mixing patterns within the piers/drydocks and
discharge points.
Solution: Implement existing hydrodynamic and fate/transport
model, CH3D, with the Lagrangian transport to address the
resolution issues for mixing in these regions.
Pay off: The product will enable and expand Navy’s managers
with additional predictive modeling tool in managing
discharge permit for Navy facilities.
Lagrangian Transport for Mixing Zone
ACCOMPLISHMENTS • Have implemented and tested Lagrangian transport
between CH3D and GNOME
• Have designed and set up virtual grid with flexible grid
resolution for the dynamic mixing simulation in the
pier/harbor
• Have analyzed and compiled dye study data in Pier 14,
drydock, PSNS, ready for model comparison
• Working on implementing CH3D for internal Lagrangian
transport

Operational Relevance:
• Provide a Lagrangian transport model for Navy
discharge permit manager to help in 1) use the
predictive model tool for better planning and
decision support, and 2) team up with regulator for
acceptance of the modeling tool.

Quantification of PCB Volatilization in Paint
NESDI Project #520
Technical Objective
How This Project/Technology Supports
the Navy Mission Cost Savings / Avoidance
Identify the relationship between temperature
and the airborne release of Polychlorinated
Biphenyls (PCBs) from representative
samples that can be correlated to welding
and cutting operations through controlled
heating and analysis.
• Welding and cutting operations require removal of
PCB paint at a radius up to 24 inches in order to
prevent personnel exposure, resulting in significant
cost, time, and waste generated.
• Accurate quantification of relevant temperature
thresholds that can result in release of PCBs will
enable optimization of the safe radius for paint
removal, reducing costs while continuing to ensure
worker and environmental safety
• Reduced time required to remove paint from
surfaces prior welding and cutting, increasing
operational tempo and dry dock availability
• Reduced waste in the form of hazardous,
PCB-laden paint and contaminated removal
media.
• Reduce worker injury from using mechanical
means to remove paint.

Dry Dock Sediment Management
NESDI Project #503
Left: Triverus MCV during sediment collection in dry dock
Right: Cleaning path over transverse channel with 2” depth
Technical Objective
How This Project/Technology Supports
the Navy Mission Cost Savings / Avoidance
Demonstrate a mobile dry-dock cleaning
and dewatering equipment suite for
• More effective management and removal of
contaminated sediment
• Increased productivity
• Reduced cost through reduction in labor and
asset use (i.e. water, treatment)
Key drivers:
• NPDES permit restricts discharge of residual solids
deposited in dry docks via sediment movement; shipyard
policy dictates that sediment be collected, dewatered, and
disposed of.
• The current cleaning process requires several man-days
to man weeks, depending on dry dock size and sediment
conditions, delaying project work and incurring significant
labor charges
• More capable, process driven mechanization will reduce
crew size, cleaning time, and volume of solid/hazardous
waste produced.
Labor Charges: current cleaning crew requires up to 6-
8 workers approximately one week; new process could
be completed in two days with 3-4 workers
Project time: Dry Docks are not released for industrial
work until dock is clean, which can result in project
delays if not completed expediently
Waste handling: more efficient dewatering equipment
will result in less solid/hazardous waste

Cost Savings / Avoidance
Preventative Management of Contaminated Silt
NESDI Project #543
• Sand traps and other surfaces must be emptied of all silt
entering the dry dock after each docking and undocking
evolution to address contamination and treatment
concerns.
These tasks require extensive pumping and entering the
confined sand trap spaces to haul out deposited
sediment.
• Reduced labor associated with cleaning sand traps
• Reduced maintenance and system strain on
downstream treatment systems when applicable due
to more complete removal of solids.
• Potential for violation and/or fine avoidance through
a gradual, but permanent removal of contaminated
sediment from the surrounding waterways and dry
dock system
NSWCCD PI: Patrick Morrow, [email protected]
To customize and evaluate the use of drop-
in passive silt collection, dewatering, and
removal devices to (1) reduce the burden of
sediment cleanup following docking and
undocking evolutions and (2) incrementally
reduce the amount of contaminants
surrounding the dry dock facilities.
Passive clarifying units can provide:
• Convenient drainage, clarification, and flush points eliminate
the need and time required to manually slurry, pump, and
shovel sediment from the low-lying dry dock areas.
• More complete recovery and segregation of sediment,
preventing its reintroduction to the environment

Multi-Functional Surface Prep Technology for Maintenance
Painting, NESDI Project #532
• Paint removal processes result in large quantities of
contaminated blast media, ultra high pressure
process water, and paint particulate, and can be
burdensome to set up and manage.
• This technology may, in some cases, provide an
alternative solution to remove, contain, and
encapsulate paint from surfaces in preparation for
maintenance and/or repainting.
• In validated scenarios, reduced time and
man-power requirements for setup vs.
traditional paint removal techniques such as
media or water blasting
• Reduced waste disposal requirements
resulting from solidified waste stream rather
than spent media or contaminated process
water.

• Modified Full Scale Unit updated by Norx LLC, packaged and sent to BAE Systems (c/o Steve Cogswell) in early Nov 2016 awaiting ship availability.
Scientific/Naval Impact:
• Provides a basis for more efficient material application and
process control while eliminating problematic overspray
emissions.
Current Practice:
• Generates overspray containing heavy metals that affect ability to comply w/NPDES permits.
• Overspray containment is costly, impacts productivity and the process generates waste that must be managed/disposed of.
