Safety First

Cautions and General Safety Rules

This manual contains important information concerning installation, operation,and proper maintenance of the shale shakers. To prevent injury to personnel orequipment damage, this manual should be read by those responsible for theinstallation and operation of the equipment. In addition, the safety precautionsbelow should be followed at all times.

TURN OFF. LOCK OUT and TAG OUT the electrical power supply to the unitbefore working on the electrical system or vibrator motors.

Lift the equipment only at lift points detailed in this manual and use properly ratedslings capable of handling the equipment weight. Look for a build up of driedsolids or stored equipment in or on the equipment that may cause the lift load toexceed those listed in this manual.

The structure on which the unit is to be installed must be capable of supportingthe operational (wet) weight of 5980 lbs.

The unit should be only installed in an area where walkways, lighting, andhandrails allow safe access for screen changes and periodic maintenance.

Remove shipping brackets prior to startup, and replace brackets before shippingthe unit to prevent damage to the loop isolators.

Never make weld repairs to the shaker basket or attach external loads, likecuttings chutes, to the vibrating components of the equipment.

Never lay tools or equipment on the screen bed. Be aware that any object that isplaced on or falls into the screen bed will be conveyed forward and dischargedonce the shaker is placed in service. Falling objects discharged from the screenbed can cause injury to persons working on or below the unit.

Inspect the unit regularly, and replace damaged or worn components only withparts supplied by the original equipment manufacturer.

Role of Linear MotionSince the introduction of linear motion shakers, drilling contractors have come torely on them to lower mud costs, minimize wear and tear on surface equipment,and to increase penetration rates. Linear motion shakers play a pivotal role inremoving fine drill solids that are likely to re-circulate through the surface tanksand adversely affect drilling operations.

The efficiency of linear motion shakers results from a number of factors. First,linear vibration creates high "G" forces on the screen deck forcing the liquidphase containing valuable mud additives through screens fine enough to capturethe vast majority of drill solids. Second, linear motion conveys drill cuttingstowards the discharge end allowing operation at elevated deck angles slowingthe conveyance rate and cuttings. Third, elevated deck angles enable a "pool" ofliquid to build up on capacity by using hydrostatic pressure in conjunction withvibration to force liquid through the screens.

Principle of OperationTwo eccentrically weighted (out of balance) motors create linear motion whenrotating in opposite directions, see Figure 1.1 (please note rotation of themotors). The force applied to the directions except in the direction perpendicularto the centerline of the rotating shafts. The force generated by the vibrators is afunction of the amount of eccentric weight on the shafts and the motor rpm. Thedisplacement of the basket along this linear vibration path determines the "G"force that the screens will impart to the slurry. The frequency of the vibration willbe the same as the rpm of the motors driving the shafts.

Desiqn FeaturesThe FS300 shaker is designed to optimize solids removal efficiency whileminimizing the cost of screen replacement and maintenance. The features thatenable the shaker to outperform competitive linear motion shakers are

Linear Motion Drive MechanismThe vibrator motors are designed for years of trouble free service. The motorsare grease lubricated and are easily serviced from the discharge end of theshaker.

Vibratins BasketThe shaker basket is fabricated from welded steel plate to maximize strength andminimize corrosion. The basket accepts three screen panels for a total screeningarea of 28.5 square feet (2.65 square meters).

Quick Screen ChanqeThe FS300 utilizes the wedge system for quick screen changes.

Deck Anqle Adiustmentln order to compensate for drilling conditions, the shaker basket is infinitelyadjustable to any deck angle between the maximum down angle of three degreesbelow horizontal and the maximum up angle of six degrees.

lnstallation

DimensionsThe dlrnensions and weight for the shaker are given in Figure 2-1. Thisinformation should be used for reference purposes only.

Liftinq informationf-itt ne snaker only at the lift points. Use properly rated slings capable ofhandling the weight of the equipment. Look for a build-up of dried solids orunsecuied equipment on the unit that may fall during the lift or cause the lift loadto exceed those listed in this manual. Use spreaders to avoid damage to unit.Lift the unit where indicated and place in position on the support structure.

Caution: DO NOT ATTACH SLINGS TO THE BASKET OR AROUND THE

VIBRATOR MOTORS.

Shipping Brackets

To prevent damage to the basket during shipment, shipping brackets areinstalled at the factory. When installed the shipping brackets prevent the basketfrom bouncing during transit.

CAUTION: SHIPPING BRACKETS MUST BE REMOVED BEFORE THESTART-UP AND STORED FOR FUTURE RIG MOVES.

Fou ndation/Substructure Req u irementsThe shaker will transmit only a mall amount of vibration through its suspensionsystem. The mud tank or support structure on which the shaker is to be installedmust be capable of supporting the maximum wet weight listed in this manual.

An important consideration in mounting the unit is that it be level in bothdirections. This is to assure even fluid distribution to the basket. Leveling isusually accomplished by shimming between the shaker skid and thesubstructure. Once level. the unit should be secured to the substructure onatl four corners bv tack welding or other mechanical means.

Flow Connectionsfne now line should be welded directly to the back tank of the shaker. Oneshould take care to ensure that the flow-line is adequately supported on pipestands or other structures so that the back tank supports a static load of no morethan one-thousand pounds. The underflow discharge may be directed to eitherside of the skid by inserting the discharge gate into the skid. A chute may bebuilt to fit into the door slides if required.

Electrical I nstallationThe macNne is wireO so that the vibrator motors can run simultaneously. Themanual starter switch has a two-position rocker switch located on the bottomedge (ON, OFF-RESET). The OFF-RESET position is the means for resettingthJmotor overload protection. The vibrator motor is a dual round device and iscompletely pre-wired to operate from the customer-specified three-phase power

supply.1. Check the motor voltage requirements before connecting power to

the unit.a .CAUTION:USERMUSTPROVIDEADISCONNECTING

DEVICE IN ACCORDANGE WITH LOCAL ELECTRICALCODES.

Z. Connect the specified three-phase power supply to the starter box.It is strongly recommended that the user refer to the NationalElectric code, Article 430, or other applicable code on motorcircuits before changing any electrical controls supplied with theunit.

3. Make sure unit is grounded.

Prior to Motor Start-up1. Visually inspect the equipment and thoroughly clean it of any dirt,

debris or foreign material accumulated during transportation.2. Check allfield wiring and power cables to assure connection to the

proper terminals.3. Match motor starter overload relay heaters with motor nameplate

information. See table below.

Operation

The FS300 shaker accepts pre-tensioned screens.

Screen lnstallationTo remo,/e and replace screens, remove hammer wedges, lift the old screen out,clean screen seating area and place the new screen in position. Then reinstallhammer wedges.

Install screens of proper mesh size for drilling conditions. Close the by-pass gate

and adjust the deck angle to the horizontal position. Start the vibrator motors bypressing the start button on the manual starter.

Adjustinq the Deck Anqle@romsixdownhi l lG2deg.) 'Ad justmentscanbemadewhile operating the unit. The most efficient basket angle will depend on thescreen type, mud concentration and flow rate. lt is recommended that the deckangle be adjusted so that the fluid covers the first hruo screens. Running theshaker at extreme deck angles can shorten screen life and allow separable drill

cuttings to degrade the screen and pass it.

Operating the By-Pass GateThe by-plss gate'diverts fluid around the screen deck. When the by-pass gate isop"n"Oi tfre ituiO from the back tank flows directly into the bottom of the shakerskid without being screened.

The bv-pass should be used when:

Changing screens while drilling when flow cannot be diverted to a second shaker

Drilling with lost circulation material

Circulating mud out of the active system into the reserve, (This wouldnormally 5" a""orplished by moving the discharge gate from one side of

the shaker to the other during the by-pass operation so that mud is

directed away from the sand trap and into the reserve)

Motor lnstallation ProcedureFollowing the procedure below and using the recommended parts will preventpremature motor bolt failure on shale shakers.

CHECK BOLT TORQUE MONTHLY.

REPLACE BOLTS WHEN REPLACING MOTORS

Each motor has a six-bolt mounting pattern. Installing one motor will require sixMotor Bolt Assemblies. Tighten the motor bolts in sequence following the starpattern shown below.

TIGHTEN EACH BOLT TO 275 FT.LBS WITH A TORQUE WRENCH

The alignment tool facilitates alignment of the bolt pattern in the foot mount of themotor mounting plate.

Follow the bolt pattern below when installing new motor assemblies.

Loop lsolatorsVisually inspect the loop isolators monthly for cracking and swelling. Replace theloop isolators once a year or as needed.

Cleaning and Repairing Screens

The fine screens used on the shaker may occasionally blind to the buildup ofsolids, scale, or salts on the screen mesh. Clean the screens in place daily usinga high-pressure water wash to dislodge the buildup and restore performance tothe icreens thoroughly before the shaker is shut down for non-drilling activitieslike tripping pipe.

Mildly damaged screens can be repaired with the use of an oil-resistant silicone.lf a screen h-as a torn top or middle layer, take the following steps to fix it:

1. Remove the damaged screen(s) from the shaker and use the basefluid to clean it (them).

2. Tear off any excess mesh that has been damaged. Leave the backupmesh in Place.

3. Apply a smooth layer of silicone over the backup mesh in order to fill inthe entire area that was removed.

4. Allow silicone to dry completely before using screen'

This repair method is only recommended in cases where less than ten to fifteenper."niof a screen's suriace area is damaged. ln cases where the damage isgreater than fifteen percent of the surface atea, discard the screen' An

6xcessively damaged screen will no work properly and will not make its intended

cut point.

Electrical

The cable used by O'Drill/MCM is armored and sheathe marine shipboard cable

and is terminated at the motor starter box and the cable gland' An armored and

sheathed cable will resist abrasion and wear but cannot prevent failure if it is

allowed to rub or vibrate against a sharp edge. Inspect electrical cable monthly
