[$_____ per _____]
The contract drawings indicate the point at which the Government will deliver
such utilities or services and the quantity available. The Contractor will be
responsible for work required beyond the indicated point to which the
Government will deliver utilities or services including making connections,
providing transformers, and disconnections. The Contractor shall clean up
the work area and dispose of debris [off station] [at a location designated
by the Contracting Officer] if any part of the mooring camels is constructed
on station.
1.7 Record Drawings: Maintain one set of full-size contract drawings
marked to show any deviations which have been made from the contract
drawings. Upon completion of the work, deliver the marked set of prints to
the Contracting Officer.
Requests for partial payments will not be approved

[1.10 Interchangeability of Camels: The design of the camels has built
into it the ability to take the double camels apart and to make two single
camels from each double camel. This is done as shown in Figure 1-1. To
provide this interchangeability, the Contractor shall use a full-scale
template for locating holes in members B1 and B4 to ensure that the frames
can be mated up to an adjacent frame or to a fender beam assembly.]
[The Contractor shall test each camel to determine and to ensure
interchangeability of units. Mating parts shall be match marked so that the
same parts that were mated during the testing can be mated again at a future
date.]
1.11 Inspection and Workmanship: Materials and workmanship shall be
subjected to inspection by the Government representative as services are
rendered. The Government shall have the right to reject inferior material
and workmanship or require its correction. If the Contractor fails to

sparks, and flame during storage, mixing, and application.

PART 3 - EXECUTION
3.1
CLEANING AND PREPARATION OF SURFACES:
3.1.1 Solvent Cleaning: SSPC SP 1. Remove visible oil, grease, and
drawing and cutting compounds by solvent cleaning.
3.1.2 Blast Cleaning: SSPC SP 10. After solvent cleaning, complete
surface preparation by near-white blast cleaning. Remove residual dust from
blasted surface by blowing with dry, oil-free air, vacuuming, or sweeping.
Provide surface profile of at least 1 1/2-mil thickness.
3.2
PROPORTIONING AND MIXING OF COATING SYSTEM:
NFSS-C39
09875-2
3.2.1 Proportioning of Epoxy-Polyamide System: Epoxy-polyamide coatings
consist of a two-component system that includes a pigmented polyamide resin,
Component A, and an epoxy resin, Component B. Mix both components in a ratio
of 1 to 1 by volume. Should the coating thicken appreciably during cold
temperature application, and thinning is necessary, or to improve application
characteristics, add up to one pint of ethylene glycol monoethyl (EGM) ether
for each gallon of the coating.
3.2.2 Mixing of Epoxy-Polyamide System: Mix components of coating by
power stirring until a smooth, uniform consistency results. Stir coating
periodically during its induction period. Follow Table 1 for induction time
and pot life of mixed batches.

COATING APPLICATION:
3.3.1 General: Apply primer coating to dry surfaces not more than 4 hours
after near-white blast cleaning. Except as specified, shop or field apply.
Apply coats of each system so that finished surfaces are free from runs,
sags, brush marks, and variations in color. Coat surfaces to minimum
thicknesses specified.
3.3.1.1 Application Method for Epoxy-Polyamide System: Allow previous
coat to dry to tack-free condition but not more than 72 hours before applying
the next coat. If more than 72 hours should elapse between coats, then clean
the surface and apply a fog coat at a minimum dry film thickness of one mil,
using the same material as the previous coat. Allow the fog coat to become
tacky, and then apply the subsequent coat.
3.3.2 Repair of Defects: Repair detected coating holidays, thin areas,
and exposed areas damaged prior to or during installation by surface
treatment and application of additional coating or by manufacturer's
recommendations. Allow a period of not less than 72 hours to pass following
the final coat before placing in immersion service.
3.3.3 Three-Coat Epoxy-Polyamide System:
thickness of between 3 mils and 4 mils.
NFSS-C39
09875-3
Apply each coat at a dry film
3.3.4 Dry Film Thickness: Provide total epoxy-polyamide system minimum
dry film thickness of 9 mils. Measure using a magnetic gage.
3.3.5 Antifouling Paint: While the last coat of epoxy-polyamide is still
tacky, apply first coat of antifouling paint. After first coat is dry, apply
a second coat. Total minimum dry film thickness for both coats shall be
4 mils.
3.4
SURFACES TO BE COATED:
3.5
FIELD TESTS:
Coat steel work.
3.5.1 Holiday Testing: Prior to installation, test for holidays in total
coating system. Use a low-voltage holiday detector of less than 90 volts in
accordance with manufacturer's instructions. After repair of any holidays by
surface treatment and application of additional coating or by manufacturer's
recommendation, retest with detector.
3.5.2 Dry Film Thickness: After repair of holidays, measure the total dry
film thickness of the epoxy-polyamide system and the antifouling paint using
a magnetic dry film thickness gage in accordance with ASTM D1186 and
ASTM E376.

APPENDIX A
PROCUREMENT INSTRUCTIONS
The plans and technical specifications provide technical data required by the
Contracting Officer to procure mooring camels.
A mooring camel is used to space a ship a given distance from the pier and to
transfer the berthing and mooring energy and forces from the ship to the
pier.
Two different widths of camels can be ordered under these plans and
specifications.
A double camel is 64 feet 1 inch (+) wide. Two double camels are typically
used to moor aircraft carriers because of the large deck overhang.
As shown on NAVFAC SD-1404046, a double camel consists of:
1 each, frame with a male tongue plate assembly.
1 each, frame with a female tongue plate assembly.
2 each, fender beam assemblies.
A single camel is 34 feet 10 inches (+) wide. Two single camels are
typically used to moor ships without a large deck overhang.
As shown on NAVFAC SD-1404046, a single camel consists of:
1 each, frame with a male tongue plate assembly (less the male tongue
plate assembly).
1 each, frame with a female tongue plate assembly (less the female
tongue plate assembly).
2 each, fender beam assemblies.
Additional fender beam assemblies can also be ordered with these drawings and
specifications.
The camels are designed to separate the double camels into two single camels
as shown in Figure 1-1. However, to provide the interchangeability feature
(the ability to make two single camels from a double camel), take special
precautions as specified in Section 01010, paragraph entitled
"Interchangeability of Camels." The interchangeability feature is costly and
therefore should not be requested unless there is a definite projected need
to use single camels.
NFSS-C39
APPENDIX A-1
Below are typical ordering examples for ordering mooring camels with the
drawings and specifications.
Example No. 1
The mooring camels will typically be used to moor aircraft carriers and
occasionally to moor other ships.
Order two double camels for each berth and do not specify that the camels
be interchangeable.
The order blank on NAVFAC SD-1404045 and in Section 01010, paragraph entitled
"General Intention" reads as follows:
Double Camels
Single Camels
Additional Fender Beam Assemblies
2 Each
0
0
This order is the most common way it is anticipated that mooring camels will
be procured with the drawings and specifications.
Example No. 2
The mooring camels will always be used to moor ships other than aircraft
carriers.
Order two single camels for each berth and do not specify that the camels
be interchangeable.
The order blank on NAVFAC SD-1404045 and in Section 01010, paragraph entitled
"General Intention" reads as follows:
Double Camels
Single Camels
Additional Fender Beam Assemblies
0
2 each
0
The single camels should consist of one frame with the female plate
assemblies and one frame with the male tongue plate assemblies.
Example No. 3
The mooring camels will be used to moor aircraft carriers and it is desired
to be able to moor two ships without a large overhang at a different time
with the same set of mooring camels.
Order two double camels and four additional fender beam assemblies.
that the camels be interchangeable.
