INSTALLATION INSTRUCTIONS
1. Deck mounting flange is attached to the bottom of the Sight Glass by four
bolts. Remove these bolts and save them. You will have (12) 1/2” - 20 x 3/4”
stainless steel mounting bolts. Store the Sight Glass upside down until you are
ready to reassemble it to the deck flange.

Failure to do so may result in damaged glass because the wiper flange extends
below the bottom glass flange.

NOTE: Use 1/8” diameter welding rod for the installation. Set welder to
approximately 125 amps.
For MIG use 0.045 wire at 190-195 amps.

2. Tack weld the deck mounting flange in place as shown in steps 1 and 2 on
page 10.
Do not clamp it to the deck in any way prior to tack welding. Please take all
possible precautions to preserve this flatness and surface condition during the
weld. Finish by welding the inside perimeter and the outside perimeter of the
flange as shown in step 3 on page 10. Failure to follow this welding procedure
can result in a warped flange that may not seal.

3. With the mounting bolts provided, sandwich the Teflon™ mounting flange
gasket between the bottom of the Sight Glass and the top surface of the deck
mounting flange. Rectorseal T Plus 2, or Teflon™ enriched sealant, should be
applied to the Teflon™ mounting flange gasket to insure that there are no leaks.
Install all (12) mounting bolts finger tight and proceed to tighten them in an
opposite rotational pattern to a torque of 12 foot pounds.

4. The Full View Model SGM-1 Sight Glass should be mounted adjacent to the
cargo control valve handwheel, with an unobstructed view of the sump and the
ladder or gauge tree. NEVER mount the Sight Glass over an internal frame which
blocks the view through the Sight Glass.

If you have any questions regarding installation contact ERL at 812-948-8484.

WARNING
DO NOT WELD UNLESS THE BARGE IS DEVOID OF CARGO AND THE CARGO
TANK HAS BEEN CLEANED AND GAS FREED. EXPLOSION HAZARD MAY EXIST.

BEFORE WELDING: SUITABLE EYE PROTECTION MUST BE WORN TO PROTECT

AGAINST EYE DAMAGE DUE TO WELD FLASH. SUITABLE NON-FLAMMABLE
GLOVES AND CLOTHING ARE REQUIRED.

Powerful NEODYMIUM #38 rod magnets are used to insure
superior coupling strength between the CERAMIN #8 float
magnet and the tri-colored gauge rod. The tri-colored gauge
rod, color coded to industry standards, is hermetically sealed
by design, to provide extended service life.

Excerpted from Federal Register, 21 Oct “94” 33CFR Part 155

Minimum Standards For Overfill Devices; Barges
The Coast Guard will allow the owners and operators of tank barges to select one of three
alternatives: (1) an overfill alarm on each tank which includes circuitry to sufficiently identify which
individual tanks’ overfill system is alarming, (2) an automatic shutdown system for the entire barge
and transfer facility, or (3) a high level indicating device installed on each tank, such as a stick gauge.

DESCRIPTION
ERL’s magnetically coupled rising stick gauge is designed to provide continuous visual liquid level
indication on the cargo tank top. The length of indication is specified when ordering and can include
full compartment depth configurations. One meter of indication reflecting the liquid level in the upper
one meter of the cargo compartment is typical and fulfills the minimum requirements set forth in
46 CFR 39.20-3(b) as well as OPA 90 requirements for overfill devices. The tricolored gauge rod with
a powerful magnet at its base is positioned inside a stainless steel pipe extending down from the
tank top. A 7” diameter float with powerful magnets inside floats up and down the sealed pipe with
changes in the liquid level. Due to the powerful magnetic coupling between the float and the internal
gauge rod, they move together providing a continuous visual indication of liquid level on the tank top.

When not in use, and with the tri-colored gauge rod lowered within the stainless steel tube, a
protective weather cap, with tether, is screwed in place. The operation is fully automatic, but the user
must remove the weather cap prior to each use and replace the cap after each use.

Operation of the APM-2 Audio/Visual Annunciator
The APM-2 tank barge liquid level annunciator panel is 24 VDC battery powered.
A stainless steel NEMA/ EEMAC Type 4, 24”H x 16”W x 8”D enclosure houses all
electrical components and the batteries are housed in a separate battery box.
Although rated for outdoor use, these enclosures are not explosion proof and
therefore must be mounted outside of the hazardous area on deck per 46 CFR
111. 105-3 1. More specifically, this panel must be mounted on the open deck a
minimum of 10 feet (3 meters) away from the cargo area (vapor source). When
mounted over the cargo compartments, the panel must be mounted at least 8
feet over the deck per 46 CFR 111. 105-3 1, K(2).
The APM-2 panel utilizes STAHL Model 9251/02
dual channel intrinsically safe repeater relays,
which are UL, FM and CSA approved for
intrinsically safe connection in Class I, II and
III, Division 1 and 2, Groups A - G hazardous
locations. The 8.2 VDC intrinsically safe sensing
circuit, of the STAHL 9251/02, safely interfaces
the annunciator panel with the normally closed
reed switches, which are located in a hazardous
location. The UL approved independently
operating reed switches are float activated to
open at 95% of tank capacity representing HIGH
LEVEL ALARM condition and at approximately
98% of tank capacity representing OVERFILL
ALARM condition. Each cargo tank is fitted with
the aforementioned sensors (switches).
Outwardly, the panel annunciator light layout
reflects the cargo compartment configuration
with an amber and red light pair representing
HIGH LEVEL ALARM and OVERFILL ALARM
respectively for each cargo compartment.
Additionally, amber High Level Alarm and red
Overfill Alarm 2,000,000 C.P. strobe lights sit atop
the panel. The front mounted audible alarms for
both High Level and Overfill have a continuously
rated sound level of 105 D.B. at 1 meter. An on/
off rotary switch with power “on” light, battery APM-2-6
condition voltmeter and red low power warning
light are also located on the front of the panel.

FIXED ALARM PANELS - APM-2

Operation of the APM-2 Audio/Visual Annunciator (Continued)
Panel operation is as follows.

When liquid level reaches 95% capacity in a cargo compartment, the high level
sensor reed switch protecting that compartment opens, breaking the intrinsically
safe sensing loop from its corresponding 9251/02 repeater relay. This relay turns
on the amber High Level Alarm light showing which specific compartment has
the 95% full condition. Simultaneously, the top mounted yellow strobe light
begins to flash and the high level audible signal sounds. After an adjustable
time period of approximately 5 seconds, the amber strobe light and high level
audible signal will shut off, yet the amber individual compartment High Level
indicator light will remain lit. When the first high level condition is achieved,
the High Level series loop of dry panel contacts feeding pins L3 and N of the
Hubbell 516B-IW Barge to Shore Receptacles open. If the barge is connected to
a dock facility, which can accept this signal, the dock will immediately be aware
of the High Level condition. In turn, each subsequent high level condition will be
annunciated as describe above.

In the event liquid level reaches 98% capacity, simultaneously the individual
compartment red overfill light will light, the red strobe light will light, the overfill
audible alarm will sound and the barge to shore connection circuit indicating
overfill alarm will open at pins L1 and L2, alerting
the dock facility of the overfill condition if the
facility has provisions to accept this signal. All of
these system conditions remain until liquid level
is reduced or the annunciator panel power switch
is turned off. With panel power switched “off” or
if the battery power fails, both High Level and
Overfill conditions will be indicated at the barge to
shore connection receptacles. If the annunciator
panel power switch is “on” and battery power
drops too low, to a value of approximately 20 VDC,
the red low power warning light will come on and
the barge to shore connection will indicate both
High Level and Overfill conditions.

During pre-transfer overfill system testing

as required in 46 CFR 39.20(b)3, all system
components are fully tested. During this system
test, battery supply voltage is clearly 0-21 indicated
and if supply voltage is less than 21 VDC, the two
series connected 12 VDC gel cell batteries must be
recharged or replaced with fully charged batteries.
Approximately 50 hours of panel operation can be
APM-2-6 expected from a fully charged battery set. As an
option, solar modules can be provided to recharge
the batteries on the barge making the power
supply maintenance free.

DESCRIPTION OF THE PV-6 II

The ERL Superac 6” High Velocity

weight operated P-V Valves operates
automatically on both the High Velocity
pressure side and the vacuum side
of each valve. All of the operating
mechanisms are located outside of the
vapor exhaust stream. This is critically
important since it eliminates valve
sticking due to contaminant build up
between shafts and bushings. The
Superac design uses sealed stainless
steel bearings at all pivot points,
which greatly improves valve set
point accuracy. This design creates
a valve, which is repeatable to 3%
of set opening point and has a total
PRESSURE EXHAUST - pressure increase of less than 10%
WEATHER COVER CLOSED from initial opening to the full open
flow rate exceeding 18,000 barrels
per hour on the pressure side. The
weather cover can be either closed
or open during operation. With this
cover closed, the pressure side of the valve exhausts through a radial 30 x 30
mesh stainless steel flame screen. The portion of the cover over the vertical
discharge section of the valve is hinged so that it may be opened to allow the
high velocity flow to travel straight up in order to effectively get the vapors
out of the deck working environment.
The focusing nozzle that directs this flow
upward is similar in construction to a high
velocity hose nozzle in that it incorporates
both an inner cone and an outer focusing
shell. This construction results in superior
performance.
The outer shell and weather cover prevent
the possibility of snow and ice buildup at
the discharge nozzle.
The pressure sides of both valves achieve a
minimum discharge velocity of 40 meters
per second even at the lowest flow rates.
This number is obtained due to the fine
finish of the inner cone, smooth air flow
path provided in the nozzle orifice and
the accurately controlled weight operated
PRESSURE EXHAUST -
opening mechanism. A damper is provided
to prevent valve oscillations or chatter on WEATHER COVER OPEN
both the pressure and vacuum sides of
both P-V Valves.

 COMMERCIAL
MARINE INC. DESCRIPTION OF THE PV-6 II

DESCRIPTION OF THE PV-6 II

The vacuum sides of both valves use a Teflon-faced stainless steel seal plate
closing against a machined stainless steel opening. This weight operated
mechanism uses a pivoting arm rather than a vertically sliding shaft to reduce
friction and improve set point accuracy. This design approach yields repeatability
of 3% of set point opening pressure. A drawer style flame screen of 30 x 30 mesh
is fitted to the vacuum inlet allowing rapid cleaning and service.

Valve operation is fully automatic and totally weight operated preventing

changes in performance over time due to spring deterioration or increased
friction within the valve.
Although the operating principal for the vacuum side of each valve is similar, the
PV-6 II has 30% fewer parts, an increased vacuum flow rate and a 16% angled
housing to insure positive drainage of any cargo condensation.

Both the pressure and vacuum sides

of the valve are equipped with test
handles which allow the operator to
easily open the valve for testing.

OPERATION OF THE ERL PV-6 II

OPERATING PRINCIPLE
The term, P-V VALVE is short for Pressure and Vacuum Relief Valve. As the name implies, the P-V Valve is
a dual function valve. Mounted on a liquid cargo vessel, this valve opens at a specific design set point
to relieve vessel tank pressure to the atmosphere. Also, in the event the liquid cargo vessel experiences
a negative pressure, or vacuum, the vacuum side of the valve opens at a specific design set point
permitting outside air to enter the vessel. Simply stated, the P-V Valve allows a liquid cargo vessel to
breath in and out within specific design vacuum and pressure levels.

The Superac™ P-V Valve Model I and Model II are both weight operated on both the pressure and vacuum
sides of the valve. This means that on both sides of the valve there is a round opening, each sealed by a
weight. The area of each opening in square inches is calculated as Pi x r² or 3.141 x 3². The area and the
sealing weight over this area directly relate to the pressure at which the valve opens. The formula for
calculating set opening point of a weight operated valve is:
WEIGHT
SET POINT=
PRESSURE PIVOT ARM 3.141 x RADIUS SQUARED
PRESSURE
FOCUSING WEIGHT PIVOT BEARING
NOZZLE 28.27 LBS. For example:
28.27 lbs.
1 PSI SET POINT=
3.141 x 3 SQUARED

This formula is the same for all weight

operated valve designs and works on
both the pressure and vacuum side of
the valve. The illustration to the left will
help illustrate the principle of our weight
operated valve.

PV Valves are mechanical devices and

they operate in a vaporous environment,
WEIGHT often laden with rust particles. Friction
14.135 LBS. within the PV Valve is a concern, because
set opening points can increase directly as
PIVOT friction increases. Therefore the adjusted
BEARING set point formula below includes friction
to more closely reflect actual conditions.
OUTSIDE
AIR WEIGHT + FRICTION
SET POINT=
TANK TANK 3.141 x RADIUS SQUARED
PRESSURE VACUUM

The ERL PV Valve virtually eliminates friction by eliminating sliding shafts and bushings within the valve.
By using sealed stainless steel roller bearings and pivot arms outside of the vapor stream, valve reliability
and set point accuracy are greatly increased.

The term, High Velocity, pertains only to the pressure side of the ERL P-V valve. This term applies to a
discharge velocity greater than 30 meters/second. Discharge velocities greater than 30 meters/second are
needed to prevent flame propagation into the barge. Per USCG regulations the vacuum side of the valve
is protected by a 30 x30 mesh stainless steel flame screen.

 COMMERCIAL
MARINE INC. TESTING OF THE ERL PV-6 II

TESTING OF THE ERL PV-6 II

Per 46 CFR 39.20-11 (b)2 the ERL Superac™ High Velocity P-V Valve has the
mechanical means to check both the pressure and vacuum sides of the valve to
verify that they open freely. Each test lever is well identified and this test is simply
performed as described in the illustration below. When testing the pressure side
of the valve it does not matter if the weather cover is open or closed. During
testing or normal operation, cargo vapors may be exhausted. Extreme caution
should be exercised as these vapors may be harmful to personnel.

On barge pressure testing or bench testing of both pressure and vacuum

valve functions can be performed by personnel trained to perform such tests.
In the case of on-barge testing extreme caution should be used to avoid
overpressurizing the barge. The test levers on both pressure and vacuum sides
of the valve should be operated to verify the valve operates freely prior to each
vessel loading.

PV-6 II PERFORMANCE

Superac 6” High Velocity PV Valve Model II mounted on collapsible vapor pipe.

NOTE: The velocity of the PV-6 discharge is measured with a precision hot wire
anemometer at the valve seat. The minimum recorded velocity of the PV-6 is 40
meters/second. At flow volumes exceeding 150 cubic feet/minute the PV-6’s flow
velocity is in excess of 50 meters/second, which is at the upper limit indicated by
the instrument (hot wire anemometer) used for velocity discharge testing.

One speed for fast take-up and cable pullout. A second speed for cable tension
and load release. This allows the user to tie barges efficiently as well as easily
tightening the cable to 18,000 lbs without a cheater bar.

• BIRDNESTING A PROBLEM?
It doesn’t have to be. The ERL winch does not reel out the cable with a violent
release like other designs. This causes bird nesting and difficulty sorting out the
cable. The ERL winch releases at your speed.

• TIRED OF REPLACING WINCHES EVERY 5 YEARS?

The ERL winch is the industry first stainless steel construction. Every exterior
part is stainless steel except the powder coated drum. The entire mechanism is
sealed inside with a permanent grease applied. This reduces your lifetime cost
and gives you value.

 COMMERCIAL DESCRIPTION OF THE
MARINE INC. 40 TON WINCH

DESCRIPTION OF THE 40 TON WINCH

The ERL 40 ton winch is the first of its kind. It is truly a revolutionary device for
barge connection. It is the first winch designed for barges that allows the user
to always be in control of the cable. This winch is designed for safe tensioning
and releasing of cable. The ERL 40 ton winch has two ratios. The high ratio allows
the user to apply up to 18,000 lbs of load to the cable. This ratio also allows the
user to release up to 40 tons at the rate the user desires. This ratio is selected
by simply lowering the lever located on the opposite side of the hand wheel.
To apply load to the cable the user simply
turns the hand wheel towards the back of the
winch. To release the load the user simply
turns the hand wheels towards the front of
the winch. This winch does not use dogs to
release the load instantaneously. The load is
released at the rate the user desires by turning
the hand wheel.

The low ratio allows the user to pull out cable

easily and take up cable quickly. This ratio
does not allow the user to apply load to the
cable. The low ratio is selected by raising the
lever located on the opposite side of the hand
wheel. To take up cable the user simply turns
the hand wheel towards the rear of the winch.
The winch can hold a capacity up to 100 feet
of 1” cable on the drum.

MARINE INC. STUFFING BOX

SUPERSEAL™ REACH ROD STUFFING BOX

• 100% STAINLESS STEEL CONSTRUCTION

ERL’s SUPER SEAL™ Reach Rod Stuffing Box is completely constructed of 300
series stainless steel. Produced on computer controlled machines to accurately
control dimensional quality, the body of the stuffing box is a massive 5”
diameter to prevent deformation of the bore from the heat of welding during
installation.

• VAPOR TIGHT PERFORMANCE

Die cut Teflon™ Packing Rings are designed to fit perfectly in each size Stuffing
Box forming an effective vapor tight seal preventing fugitive emissions. The
“T” shaped gland draws downward to lightly compress the Teflon™ packing.
two Teflon™ coated Steel nuts maintain the glands compression setting on
the packing. A grease fitting on the gland allows the introduction of grease
between the reach rod and the bore of the gland. Grease lubrication lubricates
while further reducing fugitive emissions. For best long term performance the
reach rod should be stainless steel. In any case the reach rods surface must be
smooth.

• EASY INSTALLATION
ERL stocks the most popular size stuffing boxes, as listed below, other sizes
are produced as requested. Standard Stuffing Boxes can be flush mounted,
a counterbore also permits mounting on a 2.5” ,3”, or 4” pipe. Other size

 COMMERCIAL OUTER BEARING ASSEMBLY
MARINE INC. SLEEVED(OBAS)

OUTER BEARING ASSEMBLY SLEEVED (OBAS) – 10 LS

• SELF
 ALIGNING BEARING
ERL’s OBA utilizes a self-aligning Ball Bearing. This style of Ball bearing has a
spherical outer race that allows for small amounts of angular misalignment of
the shaft relative to the housing. This reduces friction and heat at high speeds. It
also puts less bending load on the shaft, increasing life.

• TIRED OF REPLACING MECHANICAL SEALS?

ERL’s OBA gives support to the pump shaft directly above the mechanical seal.
This greatly reduces the stress on the mechanical seal from vibration caused by
the diesel engine and the pump. The result is a longer lasting mechanical seal
and less maintenance.

• 100% STAINLESS BEARING HOUSING

ERL’s OBA Housing is completely constructed of 300 series stainless steel
for long life. CNC machined bearing bore has a tolerance of +_.0004” for
exceptional fit. This allows the spherical bearing to accommodate slightly
misalignment in the pump shaft while maintaining support for the mechanical
seal.

• ALIGNMENT LIP
ERL aligns the OBA with the mechanical seal through a male snap fit. This
ensures the OBA gives the mechanical the support it needs for the longest life
possible.

CARGO GRADES
The Grade classifications assigned by the U.S. Coast Guard to FLAMMABLE or COMBUSTIBLE
liquids are defined as follows:

GRADE A Flammable liquid with a Reid vapor pressure of 14 pounds per

square inch absolute (PSIA) or more.

GRADE B Flammable liquid with a Reid vapor pressure under 14 pounds per
square inch absolute (PSIA) and over 8.5 pounds per square inch.

GRADE C Flammable liquid with a Reid vapor pressure of 8.5 pounds per
square inch absolute (PSIA) or less and a flashpoint of 80deg F or below.

GRADE D Combustible liquid with a flash point above 80deg F, but below
150deg F.

GRADE E Combustible liquid with a flash point of 150deg F or above.

RELEVANT DEFINITIONS

Reid Vapor Pressure: Equilibrium exerted by vapor over liquid at 100°F, expressed as
pounds per square inch absolute (PSIA) as defined in 46 CFR
30.10-59.

Vapor Density: This is actually a specific gravity rather than a true density
because it equals the ratio of the weight of a vapor or gas (with
no air present) compared to the weight of an equal volume of air
at the same temperature and pressure. Values less than 1 indicate
that the vapor or gas tends to settle. However, temperature
effects must be considered.

Flash Point: The lowest temperature at which the vapors of a liquid may be
ignited momentarily. Values given in the data sheets are open
cup except when designated “(cc),” which indicates the closed
cup value. In general the open cup value is about 10° to 15°F
above the closed cup value.

Flammable Limits: The range of gas or vapor concentrations (percent by volume in

air) which will burn or explode if an ignition source is present.
Limiting concentrations are commonly called the “lower explosive
limit” (LEL) and the “upper explosive limit” (UEL). Below the LEL
the mixture is too lean to burn, and above the UEL, the mixture is
too rich to burn.

a barge; also, the after part extension of a boat’s keel upon which the rudder rests.
slopesheet - the sloped vertical steel plate forming the end of the hopper barge cargo
compartment and which is part of the rake bulkhead.
specific gravity - this is the ratio of the weight of a volume of the cargo to the weight of an
equal volume of water. In the case of liquids of limited solubility, the specific gravity will predict
whether the product will sink or float on water; for example, if the specific gravity is greater
than 1, the product will sink, and if the specific gravity is less than 1, the product will float.
sponson - an addition to the side of a vessel that is outside its normal hull and which provides
added deck space and/or greater flotation stability.
spud - a steel or wooden post or pile that is placed vertically through a well in the hull of a
vessel and which, when lowered to the bottom of the waterway, anchors the vessel.
spudwell - a casing which is attached to or passes through the hull of a vessel through which a
spud is raised or lowered.
starboard - the right-hand side of a vessel when facing forward.
steamboat ratchet - a sleeve, internally threaded at the ends and with attached eye-rods,
equipped with a ratchet used to turn the sleeve, thereby pulling the rods towards each other.

vapor density - this is actually a specific gravity rather than a true density because it equals
the ratio of the weight of a vapor or gas (with no air present) compared to the weight of an
equal volume of air at the same temperature and pressure. Values less than I indicate that it
tends to settle. However, temperature effects must be considered. For example, although
methane at 68°F has vapor density of 0.55, it becomes more dense at lower temperatures. At
-259°F, the boiling point, the vapor is heavier than air. Vapors from an open container of boiling
methane fall rather than rise.
vapor pressure - the equilibrium pressure of the saturated vapor above the liquid, measured
in millimeters of mercury (760 mm Hg = 14.7 psia) at 20°C (68°F) unless another
temperature is specified.
VCG - Vertical Center of Gravity; an important computation used in the determination of the
stability of a vessel with its cargo.
VTC - Vessel Traffic Control; a central control system used in some ports to safely direct

structural discontinuity, physical rupture, or purposeful opening may occur.
wheel - another term for propeller; also, a boat’s steering wheel.
WHL - West of Harvey Lock; used with mileage designations on the Gulf Intracoastal Waterway,
Harvey Lock being mile zero.
WQIS - Water Quality Insurance Syndicate; an underwriting agency formed by various
insurance companies for the purpose of insuring against losses resulting from water pollution.
