WHATISATRANSLOADERANDADVANTAGES?

A transloader is defined as a mobile system created specifically to transfer product from a typical rail car unit to a typical transport unit. The importance of a transloader design has revolutionized the industry by bypassing the process of needing available storage to move product from rail to highway from virtually any location with an energy source compatible such as a diesel engine or generator. This system can allow any bulk distributor of product to continuously be competitive during any of the following scenarios:

• When markets are not favorable for storage of large quantities of fuel • If rail tower construction is not cost effective for smaller operations • During unexpected plant shutdowns • During planned plant maintenance operations • Peak season times when transfer operations must happen faster

HOWDOESITWORK?

Whether the transloader is a towable or motorized unit, its mobility allows for it to be setup at any desired location within a site or plant facility that has level ground. The transloader is connected to the railcar and then connected to transport after the initial setup of the transloader. The unit is connected to a power source that either can be an electrical source or supplied diesel engine to drive the compressor. Once connected to a source of power the transfer process begins until the transport is full or the desired amounts of product are removed from the railcar. The system is then disconnected and repeated as many times as necessary.

1. FIRSTTIMEUSAGEPREPARATIONS&SETUP

The first time setup of a transloader will be different from any other time unless the transloader must be moved to another location using any highway system.

The following steps are to assist in the first time usage and setup for a transloader unit:

• Move the transloader to the designated level location in which it will be used. • Upon arrival of the destination, chock all the wheels as appropriate

(See Photo Below)

WARNING: If the unit is not on level ground and the wheels chocked before setting the system up for use, the transloader can shift unexpectedly, causing serious injury or property damage as a result.

Above: Chocks placed at the base of the wheels to ensure minimal shift of the transloader due to rolling.

• Extend all of the outrigger arms out and begin lowering landing gears to ensure stability • Disconnect the transloader from the truck towing the system (if the system is not a truck mounted

unit) once landing gears and outrigger arms are set in place to begin leveling the transloader. • Ensure the transloader is stable enough before disconnecting it from the truck towing the system

(if the system is not a truck mounted unit).

WARNING: Before disconnecting from the truck towing the system (if the system is not a truck mounted unit), ensure there is not too much uplift pressure on the connection point as this may cause an unexpected shift of the truck towing the system (if the system is not a truck mounted unit) and/or the transloading system.

Above left: Landing gear at the front of the transloader is in extension ensure stability. Above right: Landing gear at rear of the transloader is in extension to ensure stability.

• Once the truck towing the system (if the system is not a truck mounted unit) is disconnected from the transloader, begin the full stabilization of the transloading system.

• Begin removing the handrails from the mobile storage location on the unit • Begin installing them in the designated locations on the transloader platform area at the top of the

unit. • Upon Installation of the handrails in the designated locations, the catwalk can now be elevated to

the desired height for transfer operations. • Once the desired height is reached, the catwalk needs to be bolted into the stationary platform

using the (4) ¾” bolts provided (the unit is equipped with (6) ¾” bolts upon request).

WARNING: Serious injury or unexpected shifts during transfer operations can result from not properly securing the catwalk to the stationary platform.

Above:Notice(4)¾”boltssecuringthecatwalktotheplatform.Notice(2)nutsforthe¾”boltsareweldedtotheoutsideofthemountingbracketforaneasierinstallationoncethecatwalkisattherequiredelevationtobesecuredtotheplatform.

• Connect hoses to the transloader using the proper acme adapters provided. • Begin the connections of the provided hoses and emergency shutoff valves to the railcar. • Ensure all valves from the railcar are in the closed position before connections are made.

WARNING: Serious injury or property damage can result if the railcar valves are not closed during the connection process.

• Begin connecting hoses provided to the transport. • Ensure all valves from the transport are in the closed position before connections are made.

WARNING: Serious injury or property damage can result if the transport valves are not closed during the connection process.

Above left: Notice the individual setting up the railcar for transfer after connecting the provided hoses. Above right: The personnel have checked the system before starting transfer operation of fuels at the transport.

• Connect inert gas to the actuator system for the emergency shut-off valves and ensure regulator and inert gas tank is set between 30 and 50 psi for the ME980 series actuators

o Ensure the ME983 railcar emergency shutoff valves are connected properly to the quick disconnect air hoses provided with a psi range no higher than 50 psi as that is the maximum functioning pressure allowed

o Ensure the emergency shutoff valves are functioning properly before starting the offloading process by opening and closing the valves from the remote stations

• Connect the system to the correct energy source for the compressor usage o Electrical connections are 3 phase/480V

WARNING: Serious injury or property damage may result if electrical systems are connected incorrectly.

• Slowly open valves to charge the system • It is best practice to start at the railcar and work down to the transport when opening valves to

charge the system (See Images Below For Valve Sequence)

Above: The (3) valves to be opened are located within the hatch of the railcar. Valve sequence shall start with the valve on the rear side of the hatch across from the pressure relief valve. The following valves shall be opened in a clockwise sequence.

Above: the yellow handle Jomar valves shown shall be opened and closed as shown, inline with the 4-way valve at the compressor. The 3” Jomar ball valve must be opened to allow liquid product to pass from the railcar to the transport.

Above: The (2) outside globe valves shall be opened starting with the vapor line which is designated by the color yellow.

Above: The (2) globe valves connected to the transport are to be opened, starting with the vapor line.

• When operating with the optional meter begin with the railcar line to start transfer operations • All meters must be calibrated before starting the transfer operations to ensure accuracy of fuels

transferred. • This will ensure the meter registers as quickly as possible • Then open the liquid piping in line to the transport then the vapor line • Ensure the vapor suction and discharge valves are open at the compressor

(See Images Above For Guidance)

WARNING: Serious injury or property damage can occur if the valves are not opened properly at the compressor.

• Ensure rail and transport pressures are translated to the correct compressor gauges. o If the correct pressures are not translated to the correct gauges ,all the necessary valves

may not be open.

WARNING: Serious injury or property damage can occur if the valves are not opened properly at the compressor.

• Press the start button on the electrical panel and monitor the system until transport is full

• Use truck gauge or gallons on meter to determine filled capacity of the transport • Upon completion shut system down by closing the valves at the transport and switching the

system start switch into the off position.

• Close valves all the system valves in the reverse order in which they were opened. • Valves should be closed from the bottom of the transport to the top of the railcar.

See Previous (4) Images Above For Valve Sequence • Disconnect hoses from the transport and rail car appropriately. • If there is pressure on the system, slowly relieve the pressure on the hoses after all the system

valves are closed.

WARNING: Propane has a low temperature for vaporization, if the valves are not closed throughout the system, pressure within the charged system can result in frostbite and other serious injuries or property damage.

• After closing the inert gas valve, disconnect the airlines from the emergency shutoff valves at the rail car system

• If the emergency shut-off valves are disconnected from the system without the correct valves being closed can cause an unexpected release of energy from the system

WARNING: Ensure all the proper valves are closed before disconnecting the emergency shut-off valves as this may cause unintentional release of energy from the system, which can result in a fire, property damage, and/or serious injury.

• Store all materials for future operation in the secure location provided on the unit. • Raise cat walk from the rail car so the railcar or the transloader can be moved • Handrails do not have to be removed unless they are required to make certain clearances from

location to location on site. • Handrails must be removed to travel on any public highways due to height restrictions • If the transloader is being moved to another location, the catwalk should be lowered to the

original position and the handrails should be removed. • The landing gears should also be adjusted so the transloader can be connected to the powered unit

properly before being relocated.

2.GENERALMAINTENANCE&INSPECTIONGUIDELINES

PURPOSEANDOBJECTIVES

This section of the guideline is intended to provide owners or operators of LPG/NGL systems the information necessary to comply with the general requirements of NFPA 58 (“the Code”) for maintaining the mechanical integrity of LP-Gas system components through maintenance manuals and the incorporated procedures.

MAINTENANCEMANUALS

Written maintenance procedures provided by equipment manufacturers may be used as maintenance manuals for the related equipment.

MAINTENANCEPROCEDURES

• Maintenance procedures are in written form in order to be used as the basis for maintaining the mechanical integrity of LPG/NGL system. Refer to Manufacturer’s Specifications.

• Whenever a change in equipment or the system occurs, the affected procedure(s) must be updated

• Propane compressor: Inspect belts, change oil and filter (Per/ Manufacturer Recommendations).

• Hoses: Inspect for cracks, cuts, gouges, wear and other noticeable damages (Per company policy).

Note: All maintenance shall be performed according to manufacturer specifications and company policy. Routine maintenance checks are a regimen that is a best practice for the industry.

MAINTENANCERECORDKEEPING

Maintenance records provide the tracking and documented verification that the facility is being properly maintained and in a safe condition in accordance with NFPA 58.

• Record Storage - Maintenance records for all fixed equipment used to store and transfer LP-Gas must be kept at each facility. For unattended facilities, these records can be maintained at the unattended facility or another designated location.

• Accessibility – These records must be available to maintenance

personnel at all times and to an authority having jurisdiction at any time during normal business hours.

• Retention – Maintenance records must be retained for the life of the

equipment,

• Troubleshooting- Refer to Manufacturer Manual on valves, pumps, electrical starter switches, etc.

MAINTENANCEPERSONNEL-TRAINING

• Individuals performing maintenance on the LP-Gas systems must be trained in the hazards of the system.

• Maintenance personnel also must be trained in the maintenance and

testing procedures applicable to the systems or equipment on which they are working.

• In order to perform the maintenance procedures, all maintenance

contractors must train the personnel under their supervision as noted in the previous two requirements, or ensure that personnel working on a system or equipment are under the supervision of a properly trained individual.

PHYSICALPROTECTIONOFEQUIPMENT

The following LPG/NGL equipment must be protected against physical damage due to impact from vehicles:

• Storage Tanks /Containers • Above ground piping, which also must be properly supported • Dispensers

SAFETYDEVICES

Additional maintenance requirements for system safety devices are as follows:

• Pressure Relief Valves and discharge piping must be protected to minimize the entrance of water or extraneous materials using rain caps or any other effective means that do not affect their operability\

EMERGENCYSHUTOFFVALVES

• Emergency shutoff valves (ESVs) and backflow check valves that are required by the Code must be tested annually for their functionality. ESVs must be specifically tested for:

o Automatic shutoff associated with thermal (fire) actuation. o Manual shutoff from a remote location. o Manual shutoff at the valve

The results of these tests must be documented. The Code does not set requirements for the retention and maintenance of these test results. Therefore, you should check with established company policy and applicable regulations for the manner in which and the length of time that these records should be kept.

• Temperature-sensitive elements (i.e., thermal links) cannot be painted nor have any ornamental finishes applied after they have been manufactured.

HOSEINSPECTIONANDMAINTENANCE

Hose assemblies used for liquid transfer must be inspected prior to each use for leakage or any damage that could impair their integrity, and no less than annually. When inspecting the hose assembly, look for: • Damage to the outer cover that exposes the reinforcement • Kinked or flattened hose • Soft spots or bulges in the hose • Damaged couplings (including loose bolts, missing parts and slippage) • Leakage • Leaking or damaged hose assemblies must be immediately repaired or removed from

service. The Code does not set requirements for the documentation, retention and maintenance of hose inspection results. Therefore, you should check with established company policy.
