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


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



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




Digital Opacity Reader Development

NESDI Project #516

Technical Objective



• Improved data collection process, accuracy, and

responsiveness for monitoring opacity in large scale

vessel recycling operations.

• Ability to accurately measure opacity in controlled

scenarios inside structures with adequate ventilation,

allowing for improved planning and decision making with

regard to production-level ventilation and surface

preparation.

• Reduced time and expense for opacity containment

through accurate opacity measurement that identifies and

contains only those scenarios producing visible emissions.

Left: Current use of MiniMPL to measure smoke stack opacity Left, below: Robust special-purpose enclosure for MiniMPL

Below: Desired operation and placement of MPL system

• Decreased personnel training costs to

achieve Method 9 certification

• Decreased containment costs associated

with preventative smoke collection

• Avoidance of potential fines during open

thermal cutting on surface ships

• Diagnostic testing ability in controlled

environment prior to production work

Modify and evaluate an opacity detection

device based on EPA-recognized Light

Detection and Ranging (LIDAR) technology for

shipyard dry dock use to supplement EPA

Method 9 during recycling hot work.




Technical Objective


the Navy Mission


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


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



Technical Objective


the Navy Mission

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.


Advance and evaluate the effectiveness of

modified surface cleaning and

decontamination gel materials for removing

paint and providing sufficiently clean

surfaces for coating.

Build upon prior Navy experience and

evaluations (SEA 04RX3, et al.) to identify

and target high value applications.

Technical Objective

• 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.
