Things To Consider Building a safer, stronger more efficient fleet is an evolution. It will

not happen immediately.

With each new build are we looking at our historical failures and how we can eliminate these failures?

Did we look for ways to improve safety or spill prevention in our equipment?

Have we looked at builds from other fields and contractors for ways to improve our builds?

Are we being non-biased when assessing equipment and human interaction? (i.e. Needs of the End User, Fleet Shop, Materials)

Arctic Self Clearing Running Boards

Traditionally running boards have had the slip hazard mitigated through:

• Studded Anti Slip Pads & Tape

• Screws in running boards

• Grip Strut screwed to running boards

• Aggressive 3 points of contact policies

OEM and after market running boards in use with BPXA, CPAI and contractors have all experienced slip related injuries with varying degrees of severity.

May 2, 2023 5

Arctic Self Clearing Running Boards In 2008-2009 the Alpine Equipment

Shop designed a heavy duty, durable running board.

The constant replacement of the OEM running boards was the primary driving force.

The final design idea uses 1 ¼” X 3/16” type IWB aluminum bar grating, 1 ¼” X ¼” aluminum flat bar & ¼” X 4” aluminum flat bar.

The 1 ¼” X ¼” flat bar was used to wrap the bar grating edge to prevent injury.

After the first units were installed it was discovered that this design did not hold mud, ice, or snow creating a safer running board.

May 2, 2023 6

Side Entry Box Van Fold Out Step

In 2014 Alpine designed a new Kenworth T440 Valve Truck in place of the old Freightliner “Bread Van” design.

The decision to use a Kenworth chassis was based on parts availability.

The decision created stairwell access problems forcing Alpine to come up with a solution other than the standard RV Step.

Using knowledge gained from the pickup running boards Alpine designed a stout fold out access step built using 1¼” X 3/16” Type IWB aluminum bar grating and square tube to provide a solid, slip resistant base step.

Recessed LED pod lighting activated by opening the exterior door provides lighting until the interior lights can be turned on.

A dash mounted warning light was installed to notify drivers if the step is in the lowered position.

This light is pressure switch activated, remaining a low maintenance layer of safety.

May 2, 2023 9

Vac Trailer Rear Dog House Steps

Vac trailers produced by Westmark have a solid, rear doghouse step with a poorly engineered locking mechanism.

The spring loaded lock seizes or comes out of alignment with the locking hole.

A better system must be used if we expect drivers to protect this needed component from the brutal North Slope roads.

The field engineered system to solve the rear step problem is a simple slide or flip lock.

Vac Trailer Front Doghouse Steps

During a 2010 refurbishment of an older vac trailer, Alpine recognized the front doghouse access step needed to be redesigned to provide a safer walking/working surface.

A full width step, level with the doors, would eliminate a fall or slip risk.

The design allowed for a second step permitting easier access.

A flip up access panel in the upper step for allowed easy access to air, electric, and camera connections.

The design originally allowed for all connections to be run under all access stairs eliminating trip hazards.

May 2, 2023 12

Tractor Deck Steps

Tractor deck stairs and handrails have specific challenges when it comes to design.

DOT standards/regulations Trailer swing. Steep, narrow riser design

Normally, short handrails are

only on the forward side of the deck and offer the driver little protection from slips, trips, and falls.

To comply with the 3 points of contact policy upright posts were welded to the top of a manufacture’s handrail.

The upright post has become

the standard answer to steep, narrow risers.

May 2, 2023 13

Tractor Deck Steps In 2010, working with Kenworth & Browns Services, a safer deck access was designed.

Removing one stair riser allowed the stair risers to be widened, decreasing the angle of the run and permits a more natural stance for ascending/descending to the tractor deck.

Angled handrails were added to both sides of the stairwell to allow 3 points of contact. The rear handrail protects the operator/mechanics from stepping into the stairwell and a potential fall. Lessons learned from incident Alpine had in 2014 prompted changes to the tractor handrail design and create new best practices for equipment

specifications.

• Rear stairwell handrail is removable to accommodate trailer swing (If Needed).• All tractors will use a 272” wheelbase to eliminate the chance of operator error, unless the application requires a shorter wheelbase.

May 2, 2023 14

Space Cap Removable Rear Access Steps

In 2012 Alpine purchased their first Spacecap.

Alpine discovered we had

not considered the safe access to this canopy.

The Alpine mechanic shop welder/fitter modified a standard box van step design.

Rather than welding or bolting to the frame the step was re-designed to use the Class V hitch the connection point.

The end user can remove the step for towing operations if needed, with no risk to the equipment.

May 2, 2023 15

Weld Body, DSO Body, Roads & Pads Body

In 2012 Alpine and Knaphide built a custom utility body to provide a safer access to the bed on our DSO and Weld Trucks.

The rear passenger side cabinet was removed to add a stairwell with hand rail to provide 3 points of contact.

This change was to provide our oilers and mechanics safer access to bed mounted equipment (i.e. welders and DSO pumps).

A custom utility body was chosen to provide the end user the ability to maintain better house keeping practices.

This design option is now given to all user groups utilizing utility bodies at the time of new equipment acquisition.

May 2, 2023 16

Flatbed Access Stairs

In 2012 Alpine began placing steps on the rear of all flatbed pickups to provide safer access to the deck.

The steps created unique challenges.

• Towing• Vendor Design• 3 Points of Contact• Property Damage

Most of the challenges have been overcome with the exception of 3 Points of Contact.

May 2, 2023 17

Volvo MCT135 Skid Steer OEM manufactures are starting to understand the emphasis on safety driven by industry end users.

As a result product selection has become more important.

In 2013 Alpine chose to try a Volvo MCT135 Skidsteer in place of the standard Bobcat rubber track skidsteer.

This decision was made based on the side door access improving the safety of our operators entering and exiting the machine.

The Volvo skidsteer design allows the use of side mirrors (provided OEM) improving visibility for the operator.

• Bobcat T190 = 1900 LBS Operating Load, 7283 LBS Tipping Load, 3250 PSI Hydraulic Pressure

• Bobcat T250 = 2500 LBS Operating Load, 7167 LBS Tipping Load, 3300 PSI Hydraulic Pressure • Volvo MCT135 = 3000 LBS Operating Load, 8628 LBS Tipping Load, 3350 PSI Hydraulic Pressure

May 2, 2023 18

Ergonomics Red Zone Reduction

May 2, 2023 19

Mechanic Shop Trucks In most equipment designs ergonomics are only incorporated for the operator.

Alpine recognized when designing equipment the access and ergonomics for a mechanic was just as important as for an operator.

Alpine has made a great effort to provide our mechanics equipment that is designed in a way to minimize awkward positions, maximize green zone components, exterior access to all components, and more space to work on componentry.

May 2, 2023 20

Kenworth T440 Lube Truck

By using drop below frame compartments and exterior access design. Alpine was able to mitigate the hazard of loading grease drums into trucks.

Alpine also used a locking slide to allow for external loading of grease drums, mitigating soft tissue injuries, pinch points, and line of fire hazards.

To further mitigate material handling hazards Alpine intends to purchase (In the future) a Birds Beak Drum Handler for the J8 mechanics shop to use with their Bobcat Toolcat.

May 2, 2023 21

Mechanics Ford Box Van Alpine purchased a new small mechanics box van (heat and start truck) in 2014.

A side entry design allowed all frequently used components to be placed to the rear of the truck.

Moving the components mitigated the trip hazards traditionally seen in rear entry box vans.

Just like in the larger box vans, all major components (I.E. genset, indirect fired heater, and rotary screw air compressor) are accessible from the exterior of the truck and mounted on locking slides.

May 2, 2023 22

Kenworth T440 Box Vans

By once again using the drop below frame compartments, exterior access, and locking slides for side mounted generators.

Alpine was able to improve the ergonomics for mechanics working on these generators and mitigate soft tissue injury and pinch points.

The locking slide allows for fast safe replacement of any major component (I.E. engine, generator end, genset)

using mechanical means mitigating soft tissue injury, pinch points, and crushing hazards.

May 2, 2023 23

Custom Weld Bodies Alpine’s custom weld bodies are an adaptation of a pipeliner weld body.

Removing the forward drivers side compartment allowed us to mount a welder in a manner allowing the operator to access all welder controls from ground level.

The utility body cabinets allow the end user to practice safe housekeeping, allowing an open work environment for Mechanics and Oilers to access the welder.

May 2, 2023 24

Custom Weld Bodies The addition of a double wide, five foot tall cabinet allowed placement of our gas bottles and

regulators safely in a cabinet out of the weather and other potential damage sources.

This cabinet incorporates a ¼” plate dividing the 2 compartments. Each compartment is independently vented and equipped with bottle clamps or tie downs.

The lower bottle height allows the operators to easily load the gas bottles from ground level.

May 2, 2023 25

Tank Straight Truck Lowered Doghouse

In 2010 Alpine received its first new tank truck in 5 years.

The rear doghouse was lowered placing the connection points and hose reels at a more ergonomically correct height for the operator.

The design opened up

space in the doghouse, allowing more space for mechanics to work on componentry in less awkward positions.

This has become a standard for all new builds done by Alpine.

May 2, 2023 26

Chemical Truck Redesign (Conceptual)

The continuous improvement in equipment design for end users and mechanics has lead to a 2015 redesign effort to build a side compartment chemical truck in cooperation with West-Mark.

The design allows a user more positive process safety controls and ease of access and the servicing mechanics improved access to components for mechanics.

With this design Alpine was also able to increase capacity of the tank from 90BBL’s to 161BBL’s, minimizing the number of fill transfers and spill potential.

The increased capacity only increased the truck length1.5 feet beyond a standard 90BBL truck.

May 2, 2023 27

Tractor Headache Rack Hose/Electrical Connection Bulkhead

The 2010 tractor headache rack redesign incorporated a removable hose/electrical bulkhead.

Previously mechanics worked under the chassis in between cab and headache rack.

The small modification gave Alpine mechanics the ability to repair hydraulic hoses, electrical/camera cables, air lines and connections in a safe and un-cramped position.

May 2, 2023 28

Process Safety & Asset Protection

May 2, 2023 29

Therm Dynamic Flameless Heater

Process Safety Management improvements in early 2013 Alpine researched flameless heater options.

In 2014 Alpine purchased two Therm Dynamic TD1200 Heaters after a trial in the 2013 winter season.

The Therm Dynamic produces heat in two ways • Primary heat is produced through low pressure hydraulics. • Secondary heat is converted and recycled from engine exhaust.

Optional improvements for process safety included Chalwyn Air intake shutdown valves and a brushless alternators.

May 2, 2023 30

Tioga Heater Explosive Gas Monitor/Run Away Protection

Indirect fired heaters have been a process safety concern industry wide.

The concerns have greatly gone unaddressed (in Alaska) outside of using the hot work permit standard.

In 2013 Alpine did a single Tioga Refurbish as part of the PSM program & added two safety features to the heater.

• Explosive gas monitoring system

• Engine runaway protection (Using experience learned from Therm Dynamic Heaters)

Each device has limitations and added maintenance requirements.

May 2, 2023 31

Tioga Heater Explosive Gas Monitor/Run Away Protection

The explosive gas monitor is an intrinsically safe gas atmospheric monitor designed to shut down the burner if it senses gas levels at a dangerous level.

The explosive gas monitor requires an annual calibration to work properly.

The Chalwyn air intake shutdown valve provide overspeed shutdown protection for diesel engines.

The valves completely block the air intake system cutting off an uncontrolled external fuel source and air.

These are an industry standard used on all equipment utilized in Canadian oil fields.

May 2, 2023 32

Loader Tires A balance of longevity, cost, and traction must be found when purchasing tires. Traditionally harder

compound tires have been used on the slope compromising traction for longevity. In 2009 heavy equipment operators requested the Alpine Equipment Shop find a long lasting tire that

would provide more traction than standard rock lug tires.

The best solution came in the form of natural rubber or softer synthetic rubber compound tires. On Volvo L120 and smaller loaders Bridgestone VSM Snow Wedge tire was chosen. On Volvo L150 and larger loaders Bridgestone VKT V-Steel tire was chosen.

Both tires have proven to be long lasting and provide a superior form of traction than previously used tires.

May 2, 2023 33

Skid Steer Tracks When Alpine acquired the second Volvo MCT135 Skidsteer Loader

Alpine chose to have it upfit with Bridgestone Polar Tread Tracks.

This trial is still ongoing but to date the Bridgestone tracks have proven to be a superior track in all seasons.

Vac Trailer Front and Rear Doghouse Noise

Employees and their health are our most important asset.

At this time we are unable to engineer the noise hazard out of our Vac Trailers.

Alpine Drilling Support, in an effort to protect themselves and their fellow coworkers, took it upon themselves to have safety do noise testing and place warning signs on both front and rear doghouses.

Equipment Lighting and Visibility

May 2, 2023 36

Tractor Headache Rack Headache racks continued their evolution in 2015 with additional modifications to be made Brown’s Services during

manufacturing.

Alpine added a framed, drop down screen to the rear window to allow the operator easy access to clean the rear window.

Alpine also added outer screens to accommodate the addition of cab corner windows allowing for better lateral visibility from the cab.

May 2, 2023 37

Phase Condition/Convoy Strobe Light

Following an incident during the 2009-2010 ice road season, Alpine began putting blue strobe beacons on the rear of all equipment that may be involved in Phase Condition Convoys.

This has become a standard upfit within specifications to all 90BBL Trucks, Vac/Tanker Trailers, and Boxvans.

Adding NFPA chevron striping to the rear of all 90BBL Trucks, Vac/Tanker Trailers, and pickup tailgates is also being researched to improve visibility.

May 2, 2023 38

90BBL Scene Lighting

Recognizing most of our work occurs in the dark the need for scene lighting to be readily available was addressed in 2015.

For years all box vans and pickups have been equipped with work lights.

In 2015 side lighting was added to 90BBL Trucks to compliment the rear work lights.

Alpine is using a Vision X 8” X 5” LED light on the front and rear of both sides of all tanks.

This will provide better lighting for operators at worksites with limited lighting.

May 2, 2023 39

Cabinet Lighting Lighting on a is key to employee safety.

LED rope lights or LED pod lights are included in all Utility Body and Boxvan Cabinets.

By including cabinet lighting it provides team members the ability to easily see the materials in the space on the darkest worksites.

The lighting eliminates the need for bulky headlamps or removing a hand to use a flashlight, and allows employees to concentrate on the task at hand.

May 2, 2023 40

Antiglare Hoods In response to a recent incident Alpine Drilling Support and Equipment Services decided all new

tractors (starting in 2016) will be equipped with Anti-Glare hoods.

Alpine was already using anti-glare paint on the front doghouse doors of some of our Vac Trailers.

If this shows to be of benefit, the project will be expanded to pickups and boxvans in the future.

Currently this will only be done at time of accusation and not be a retrofit on existing equipment.

May 2, 2023 41

Equipment Backing

May 2, 2023 42

Backing Aids Incidents while backing equipment and light vehicles have plagued the North Slope for many years.

Alpine has backup cameras on almost all equipment, reducing the number of backing incidents but not eliminating them.

In 2016 Alpine will be testing the Brigade Backsence Radar backup system on one new truck in an effort to eliminate backing incidents.

This system has great potential for equipment with limited rear visibility.

May 2, 2023 43

Spill Reduction and Equipment Integrity

May 2, 2023 44

Hydraulic Return Filter Placement

In 2014 Pall Filter Corporation discontinued the 8200 series hydraulic return filter and replaced it with the UR319 series.

Traditionally the hydraulic return filters were mounted to the frame rail of straight trucks.

Alpine, not having experience with the replacement filter housing, requested Westmark mount these in the rear doghouse of two new 90BBL trucks.

Where applicable all hydraulic return filters are mounted where any leaks that may occur can be contained.

May 2, 2023 45

Heated Hydraulic Tanks

In 2012 Alpine installed Arctic Fox Hydra Liner glycol heaters into all tractor mounted hydraulic tanks.

Keeping the fluids near operating temperature reduces pump wear and cavitation.

Reduced spill potential due to the reduced thermal expansion and contraction of seals was a side benefit.

Hydraulic hoses also benefited through having warm fluid run through them instead of having to exercise hydraulics before having warm fluid.

In 2013 with the introduction of the AHG the hydraulics are able to now kept warm while the primary chassis engine is not operating.

May 2, 2023 46

Redesigned DSO Pump and Truck Alpine’s redesigned DSO trucks brought redesigned DSO pump units.

New DSO pumps are fully contained to prevent any fluid release.

Hose and controls are protected from environmental condition in a sealed cabinet.

As an added benefit controls and hoses are at an ergonomically correct position for operation from ground level.

May 2, 2023 47

Enclosed Day Tank Hose Reel and Filter In 2014 and 2015 Alpine designed two utility bodies requiring day tanks.

In an effort to minimize potential leaks the forward driver side cabinets were used to contain all componentry less the pump.

Both cabinets incorporate containment pans to further mitigate spill potential.

Added benefit include: Reduced hose degradation by not being exposed to environmental conditions and ultraviolet rays. Reduced potential of tampering due to the units being concealed.

May 2, 2023 48

Double Walled Day Tanks

In 2013 Alpine began to provide double walled day tanks and bulk tanks for mobile equipment.

This provided a layer of protection from rub through and puncture on the tanks while providing a secondary containment in the event of primary tank failure.

This has become a best practice on the Alpine field and all new day tank or bulk tanks for mobile equipment are ordered double walled.

May 2, 2023 49

Vac Trailer Air Intake Shroud

In the spring/summer months of 2015 Alpine preformed an experiment to prevent overheating of the pony motor.

Through an incident in 2014 (previously addressed) that the doors of the lake water vac trailer had to remain open.

The Alpine Equipment Shop had an air intake to radiator duct built to direct the air flow directly to the radiator which completely eliminating the engine overheating issue.

Alpine is now in the process of redesigning the front doghouse of Vac Trailers in all future new builds and refurbished units.

Modifications to include:• Engine moved closer to air intake• Thermostatically controlled louvers• Modified curbside doghouse

structure to allow lateral slide out of engine

May 2, 2023 50

Gates Chemical Hose

In 2009 the Alpine Equipment Shop Materials found a low temperature, chemically compatible hose for use on our chemical trucks.

The existing Goodyear Arctic Flexwing hose was on a 6 month replacement program.

The Gates Chem Master Extreme (Formerly Gates Stallion) was selected.

Gates was able to meet compatibility with all chemicals being transferred, provided a -40 degree rating, and still provided hose flexibility.

Alpine now replaces chemical hoses about once every two years instead of every six months and has reduced the risk of internal hose degradation.

May 2, 2023 51

In 2008 Alpine Equipment Shop Materials found true arctic grade, high pressure, hydraulic hose.

A field test of Aeroquip, Parker, and Weatherhead hoses was conducted.

After one complete winter season the results were:

• Aeroquip 5 failed hoses• Parker 1 failed hose• Weatherhead 0 failed hoses

All new equipment purchased by Alpine is now upfit at the vendor with the appropriate arctic grade hose.

The only high pressure hydraulic hose used today at Alpine is the Eaton EC810 (Formerly Weatherhead H487) rated for -69 degrees

Eaton EC810 Arctic Grade Hydraulic Hose

May 2, 2023 52

Emissions and Fuel Consumption Reduction

May 2, 2023 53

Kenworth T440Cummins ISL9

In 2012 Alpine chose a new model (T440) class 7 Kenworth chassis for their new valve truck build. This chassis was chosen for it’s smaller size and suitability for a Box Truck.

By using the Cummins ISL9 Alpine was able to reduce fuel consumption and emissions.

Alpine has experienced less emissions issues than with tractors with the Cummins ISX15.

The smaller engine operates at higher temperatures, making it more conducive to a exhaust filter regeneration.

This chassis has become the standard platform for all large Box Trucks and 90BBL Trucks unless the application requires more than 74000 pounds GVWR.

May 2, 2023 54

Puritan AHG

Alpine’s test of 11 Puritan AHG units has proven to be successful.

Alpine has seen on average a 45%-55% reduction of operation time on primary chassis engines on units equipped with the AHG.

The best results are seen when chassis are upfit with AHG at time of acquisition.

May 2, 2023 55

Applications of Puritan/Ventech Products

May 2, 2023 56

Chassis Mounted Arctic Heat Generator

The Puritan AHG allowed Alpine to reduce heavy truck engine operating time by an average of 53% during the 2014-2015 ice road season.

With an average of 53% reduced operating time Alpine will be able to extend replacement schedules having a large impact upon the way capital budgets are spent.

Alpine was able to reduce fuel costs by $100,288.80 across 8 units, an average fuel savings of $12,536.10 per unit. (Based on $4.00 per gallon)

Averaged AHG hourly cost of operation (fuel & maintenance) is $2.83.

Largest benefits seen when the AHG is installed at time of equipment acquisition.

Larger savings are expected as the project continues and expands to other applications.

To make this work Alpine needed involvement from management to equipment operator.

Auxiliary Unit & Primary Engine Mounted

In 2015 Alpine received two new 5500 Gallon Tank Trucks. One Diesel/Urea Dispensing Truck and one Potable Water Truck.

Each was equipped with dual heating system.

The new Diesel/Urea Dispensing unit was done out of necessity.

Chassis mounted AHG provides heat to the chassis, tanks, and doghouses without the main chassis engine operating.

The primary chassis engine mounted Liquid Heat Generator maintains the primary engine at operating temperature allowing for a cleaner burning engine and better regeneration.

May 2, 2023 58

Generator Engine Mounted Liquid Heat Generator

Tier 4 engines in non-mobile equipment bring a new challenge as to how to maintain engine and exhaust temperatures in the arctic.

In early 2015 Alpine received their first Final Tier 4 Generator equipped with a engine mounted Liquid Heat Generator.

By doing this the engine is kept under constant load maintaining proper operating temperatures and increasing exhaust gas temps.

With the increased exhaust gas temperatures wet stacking is eliminated and efficient engine regeneration occurs.

May 2, 2023 59

Future Applications

By the end of September 2015 Alpine will have replaced the generator on their 150 Ton Linkbelt Crane with a 24 volt AHG tied into the upper engine.

A 12 volt AHG will still need to be placed on the 150 Ton Linkbelt Crane for the carrier engine to see maximum benefit.

Alpine is exploring testing some pickups upfit with Ventech Liquid Heat Generators in an attempt to increase exhaust gas temperatures to improve engine regeneration. This will also improve cab heat.

In the future a 2 cylinder AHG may be used in boxvans with invertors to provide heat and 12 volt power to the chassis engine, cab, and box.

Alpine is exploring the option of retrofitting Boxvan generators with Ventech Liquid Heat Generators in turn making the generator a Heat Generator. This would maximize their existing infrastructure.

May 2, 2023 60

Diesel/Urea Dispensing Truck

May 2, 2023 61

Diesel/Urea Dispensing Truck

In an effort to improve efficacy Alpine built a Diesel/Urea Dispensing Truck delivered in the spring of 2015

This is a duel tank (1000 Gallon Front Urea Tank and 4500 Gallon Rear Diesel Tank).

Front tank is heated in the winter months via duel heating system (AHG for non-operating and Liquid Heat Generator for operating).

Heat system incorporates thermostatically controlled valves to prevent overheating of urea.

May 2, 2023 62

Side Mount Urea Dispensing Unit

Side mounted dispensing compartment was chosen to prevent accidental cross contamination of equipment tanks.

Urea nozzle is a OPW 21Gu with Mis-Filling Prevention Device to prevent accidental cross contamination of equipment tanks.

All stainless steel plumbing, pump, and hose reel are used to prevent corrosion.

Titan Logix level gauge with overfill prevention was used to prevent accidental bulk tank overfill.

A cat heater tied into the AHG heating circuit was used to maintain heat in the side cabinet to prevent freezing of the Urea.

May 2, 2023 63

Diesel Dispensing Unit Using a drop below frame rear doghouse opens space for mechanics to access plumbing and mechanical componentry.

Alpine uses Cim-Tek water absorbing filters plumbed in parallel to prevent water contamination in equipment.

All plumbing is stainless steel with Victaulic gaskets for added ease of removal of components.

Titan Logix level gauge with overfill prevention was used to prevent accidental bulk tank overfill.

An Arctic Rated (-65 Degrees) OPW 7H diesel nozzle was used. (non-standard 7H nozzle)

Three Magnalight 12 volt LED explosion proof were used in the rear doghouse for improved lighting and longevity.

May 2, 2023 64

In Closing Building a safer and environmentally responsible fleet takes time. It is an evolution.

We must be able to see deficiencies within our builds and be willing to correct those deficiencies in future builds.

The input of end users and mechanics is vital to building a user friendly fleet.

We must encourage our end users and mechanics to look for ways to improve our equipment and share those thoughts with us.

Equipment Management Professionals must keep an open mind and leave behind the “we have done it this way for 20 years” mentality.

We will never make equipment perfect for everyone, but it does not mean we do not try.

May 2, 2023 65

In Closing Cultures will drive how fleets develop. Alpine’s fleet developed as a

result of the cultural shift.

In the current economic state we will need to find a balance between Safety, Environmental, and Cost.

Each Fleet Manager will need to decide where of these three items fall in priority.

Cost will always maintain a high priority, but expectations have been raised on providing safe and environmentally responsible equipment.
