4. OPERATIONS

WARNING: Do not touch the VES-CL Elevator, unless hydraulic power is disconnected.

WARNING: Never open the elevator when the pipe load is still suspended by the elevator.

WARNING: Observe the elevator continuously while closing to check if the elevator is properly

closed. The CL-250 Elevator PN 612900-Y-H-T is WITHOUT closing signal, therefore extra caution

needs to be taken to ensure that the elevator is properly closed BEFORE picking up any load.

Safety

Make sure that ALL hydraulic lines are isolated (disconnected) before any work is•

carried out on the VES-CL Elevator.It is recommended to have the VES-CL Elevator operated by the driller.•

The VES-CL Elevator is activated with a remote control valve, which may be actuated by hand•

or foot depending on the type of valve and/or HMI-interface.

The driller (and or the floor man) must coordinate operation of the elevator and slips/spider so•

one tool is engaged around the tubular before the other is disengaged. Thus, one or both tools

continuously suspend the tubular during all stages of pipe handling operations.

Operation Running in / Tripping

The CL-250 elevator is lowered around the tooljoint and the command “close elevator” is given.1.

A signal is given to the driller when the CL-250 elevator is closed2.

NOTE: Only for elevator model 612900-Y-H-TF with closing signal)The pipe is made up.3.

The driller lifts the CL-250-elevator in order to pick up the load.4.

The slips/spider is commanded to “open”, simultaneously, the driller picks up the elevator while5.

the driller raises the spider/slips.

The driller lowers the string into the hole.6.

The driller sets the spider/slips.7.

Open the CL-250 Elevator and pick up a new section of pipe.8.

Operation Running out / Tripping

The CL-250 elevator is lowered around the tooljoint and the command “close elevator” is given.1.

Observe the CL-250 Elevator is closed when the “elevator closed indication signal” is visible.2.NOTE: Only for elevator model 612900-Y-H-TF with closing signal

Raise the spider/slips.1.

Pull out the string.2.

Close the spider/slips3.

Release the stringweight from the CL-250 Elevator by lowering it slightly4.

MAINTENANCE

& INSPECTION



30


Daily Inspection

The Function of the Feedbacksignal has

to be checked daily.

Locking of screws

All screws are normally secured by

mechanical bolt lock or with a lock wire.

Grease quality

In order to achieve efficient greasing

even at different environmental

temperatures, we recommend the

following grease types should be used(obtainable from Blohm + Voss Repair

GmbH):

multipurpose grease, for example Shell

Alvania RL 3

General

WARNING: For service and maintenance

activities, make sure that no hydraulic

pressure exists on the elevator and that

the connecting lines are disconnected.

Lubrication

The elevator needs to be lubricated

regularly on the following points. Use a

grease gun:

Grease points:

on top and bottom of the latch pin1.

(2 nipples each)

lubricate springs daily2.

check and lubricate latch opening3.

arrangement daily

hinge pin (1 nipple).4.

Gap orno Gap?

To indentify the conditions of the 18°

Elevator taper gauges are available for

all B+V Elevators (P/N 600018). A set

of gauges consists of an 18° gauge

(GOOD) and a 15° gauge (BAD)

How to check the bushing the

correct way

Fit the gauge to the inner1.

bore of the bushing

Push the gauge against the2.

bushing and start to move the

gauge downwards until the chamfer

touched the 18° shoulder.

Check the result as follows3.

Bushing Wear Check1.

1.

2.

Wear of Equipment

Normal wear of bushings and elevator

ears caused by usage will eventually

reduce the load capacity of elevators.

The existence of cracks or the

appearance of defects can indicate

severe deterioration and even failures.

Prompt attention is required eitherto remove the elevator from service

immediately or to undertake appropriate

repair.

A wear condition in its early stages is

common. Frequently, it results in a tool

joint sticking to the elevator.

Elevators showing hammer marks

around the top of the bore should be

closely examined to determine whether

it is the elevator, the tool joint or both

are faulty. WARNING: If the taper is less than 15°

take the elevator out of service or

exchange the bushing.

If the taper is between 18° and 15°,

reduce the elevators load capacity to

90%. Never use the elevator without a

bushing.

Check of results

Using the GOOD gauge: If the gauge1.

sits directly on the bushing without

showing any clearance between gauge and

bushing, the bushing is OK.

If the gauge shows space between the2.

gauge and the bushing, you have to checkwith the second gauge.

Using the BAD 15° gauge: If the gauge3.

shows any clearance between gauge and

bushing, the bushing is OK.

If the gauge sits directly on the bushing4.

without showing any space between gauge

and bushing, take the elevator out of

service.

Function of Valve

When the elevator is fully closed and

latched, the valve is actuated. Therefore

hydraulic pressure passes through and

pressurizes line “C” (Elevator closed

signal). The signal indicates the operator

that the elevator is properly closed and

latched.

Adjustment procedure FeedbackValve (Closing Signal)

In case the elevator does not give a proper

closing signal, the feedback valve may be

in need of readjustment. To check if this

is the case, close the elevator. When the

elevator is fully closed, move down the

valve roller manually. If a closing signal

occurs, the valve has to be readjusted. If

no closing signal occurs, it is possible the

valve is damaged or defect and has to be

replaced.

Procedure to readjust the valve :

unscrew the screws at position 28 and•

disassemble the protection cover

loosen the screws at position 35 slightly•

move the valve slightly upward by•

turning the adjustment screw at

position 31

Warning: be carefull moving the valve

upward, only a small distance may benecessary. If the valve is placed too

high, it can be crushed when closing the

elevator.

tighten the screws at position 35•

check the closing signal by closing the•

elevator

if there is still no signal, move the valve•

a bit higher and check again, repeat till

the closing signal works

After successful adjustment, make sure

all screws are tightened and all safety

elements are in place.
