Overfill Prevention
September 25, 2017

2. Automated Tanker Over Fill Prevention
• Tanker Overfills occur through a multitude of situations:
• Human Error
• Mechanical Failure
• Policy Violation
2

3. Historical Alpine Recordable Spills
• CD3 02/18/2015
• 2 Gallon(s) 100% Diesel (Class II).
• Manual & Digital Float Gauges Obstructed with Frac Sands.
• Frac Sand Caused Floats To Get Stuck Resulting In Lower Tank Volume Readings.
• Cleanup Cost(s): $1412.25 + Transport & Disposal (Class I Disposal Well CD1-01A).
• CD2 03/11/2015
• 0.05 Gallon(s) 80% Seawater/20% Schmoo-B-Gone.
• Ball Gasket missing from 325BBL product misted out scrubber stack.
• Foaming issue.
• Cleanup Cost(s): Unknown (Beneficial Reuse) .
• CD3 03/04/2016
• 5 Gallon(s) 100% Crude Oil.
• Both Pump Levers (Duel Pump Configuration) Actuated, Allowing Second Pump To Overcome First
Pump Backflowing Crude Oil To 325BBL Tanker.
• Human Error.
• Cleanup Cost(s): $1672.89 + Transport & Disposal [Class I Disposal Well CD1-01A (Snow/Fluid) &
Grind/Inject (Gravel)]
• CD2 04/07/2017
• 110 Gallon(s) Seawater.
• Seawater Transfer From 325BBL To Coil Tubing Unit (3rd Party Contractor).
• Currently Used Configuration Would Not Protect Against This Incident, Unless Coil Unit Was/Is
Equipped With Same Configuration.
• Cleanup Cost(s): $ $1300.72 + Transport & Disposal (Class I Disposal Well CD1-01A).

4. Traditional North Slope Means of Fluid Level Monitoring
September 25, 20174
• Sight Gauges:
• Sight Glasses Break if Unprotected
• Gaskets Leak
• Tubes Require Cleaning
• Low Accuracy (Tank Volume)
• Spill Prevention Reliant On Operator
• Mechanical Float Gauges:
• Tank Entry Required For Repairs
• Float Ball Can Get Stuck In Heavy Fluids
• Requires Tank Cleaning to Maintain
• Low Accuracy (Tank Volume)
• Spill Prevention Reliant On Operator

5. Traditional North Slope Means of Fluid Level Monitoring
September 25, 20175
• Magnetic Float Gauges:
• No Tank entry required for repairs.
• Reliable in light fluids.
• Medium level of tank volume accuracy.
• Measurement by Percentage not
BBL’s.
• Spill prevention reliant on Operator.
• Digital Float Gauges:
• Tank entry required for repairs.
• Float Ball Can Get Stuck In Heavy Fluids
• Requires Tank Cleaning to Maintain.
• High accuracy tank volume, but can be
affected by foaming.
• Can be used for Overfill Warning
System.
• No compensation during transport to
override warning system.
• Spill prevention reliant on Operator.

6. Guided Wave Radar Vs. Level Float Gauges
Guided Wave Radar
• No moving parts
• No tank entry required for
maintenance.
• Works using fluid dielectric
values.
• Not affected by foam or fluid
temperature.
• Optional probe
materials/configurations for
optimal chemical/fluid
compatibility.
• Communication wire options.
• Hardwired option preferred for
North Slope applications.
• Better volume accuracy.
Level Float
• Movement of float/arm to read
volume.
• Float can get stuck in heavy
muds/fluids.
• Requires regular tank cleaning.
• Requires tank entry to maintain
(confined space).
• Tank volume measurement(s) can
be effected by foam.
• Varying option of Mechanical,
Magnetic, and Digital.
• Tank volume accuracy from poor
to good depending on style level
float used.
• Mechanical=Low Accuracy.
• Magnetic= Medium Accuracy.
• Digital= High Accuracy.
• Effected by foam.

7. Automated Tanker Over Fill Prevention
7
• Conoco Phillips Alpine has adopted a
Fail Safe system/process to prevent
overfills.
• Using Titan Logix® TD80™ guided wave
radar level gauging Alpine has
implemented a three (3) tier overfill
warning/protection system.
• Tier One (90% Tank Capacity):
• Red Beacons (interior and exterior)
and Alarm activate (operator
acknowledges).
• Tier Two (93% Tank Capacity):
• Red Beacons (interior and exterior)
and Alarm activate. Air actuated valves
shut in.
• Operator acknowledges and clears
hoses.
• Tier Three (Preprogrammed by
Manufacturer):
• Red Beacons (interior and exterior)
and Alarm activate. Air actuated valves
shut in.
• Operator unable to acknowledge must
off load below spill setting to reset.

8. Finch II Control/Display Operation
• Buttons:
• Comp Select=Compartment Select
• Two (2) Compartment Capability.
• ACK=Acknowledge
• Horn Bypass=Horn Bypass
• Used for servicing operations only.
• DIM/SLEEP=Display Power On/Off
• Lights:
• Level 1=25% of total tank volume.
• Level 2=50% of total tank volume.
• Level 3=75% of total tank volume.
• Level 4=100% of total tank volume.
Quick Reference Operator Should
Use Digital Readout For Volume.

9. Operation Instructions for Drivers
• Signage for all units equipped with overfill protection (Finch II Display).
Titan Logix Operations
Startup Operations:

12. Simulated Spill Mode
12
• Spill mode is the Final Fail Safe Mode
• Spill Mode is not overridable.
• Spill setting is preprogramed by Titan Logix® based on strap chart calibration
(7 ½” down guided wave radar probe).
• Fluid level must be lowered below spill setting to reset system.

13. Truck Racking Compatibility
• Static Ground Verification:
• Compatible with permissive ground
systems.
• Involve Manufacture when wiring for
isolated and non-isolated grounding.
• Meeting existing infrastructure
requirements.
• Optical Truck Rack Modules:
• Compatible with all standard/traditional
Optical Truck Racks/Modules.
• Finch II Display/Control Module
equipped with preexisting terminals for
easy upfit/retrofit.
• Non-Traditional North Slope
Infrastructure.
• May be easiest solution to complying with
International Fire Code 3406.5.1.10
Bottom Loading.

14. Truck Racking Compatibility
September 25, 201714
• Scully Signal System:
• Truck Rack Modules:
• Float Limit Switch (COTU):
• Compatible with Float Limit
Switch’s.
• Breaking Isolated Ground.
• No loading Rack reconfiguration
required.
• Involve Manufacture when wiring.
• Custom Rack:
• Not recommended by manufacture.
• Alpine Developed.
• Communicates directly with facility.
• XV Valve automatically closes if the
bulk tank or tanker hit 90% capacity.
• International Fire Code compliance
was met through communication
between truck and facility
(communication is accomplished
though SetSim).

15. Retrofit and Expansion of Program
• Currently Conoco Phillips Alpine is operating Two (2) 325BBL Vac
Trailers, One (1) 240BBL Dust Control Trailer, and One (1) 130BBL
Chemical Truck with Valve Control Shutdown.
• Retrofit:
• Onsite retrofit costs are ~ $6285.00 +/-
• Retrofit can easily be done anywhere there is an existing Garnet® See-Level™
Gauge or 1” NPT penetration.
• Conoco Phillips Alpine has began retrofits of Wells Support Group 100BBL,
240BBL, and 325BBL tankers.
• Conoco Phillips Alpine will began retrofits of Drilling Support Group &
Roads/Pads 100BBL, 240BBL, and 325BBL tankers no later than summer 2018.
• Expansion of Program:
• Conoco Phillips Alpine is currently exploring using this system to monitor load
levels of stationary and portable 400BBL/600BBL/Tiger/Open-Top tanks at the
truck/trailer level gauge.
