Baoye FY-50Y BOP Handling System

FY-50Y BOP Handling System

Baoji Engineering Hydraulic Components Plant

I. Profile

FY-50Y BOP Handling System is designed to meet requirement of installing and

removing BOP stacks. The system is full-hydraulic control and can be used for

heavy and medium duty drilling equipment. The main function of system is to lift

and install single BOP or BOP stacks. The system features with explosion-proof,

easier operation, better reliability, and safety. It consists of left and right BOP

moving device (each hung on one guide rail below drill floor), hydraulic control

box, pipelines, and hose hangers. Controlled by hydraulic operating box, the

system can achieve the movement of rising, lowering, moving forward and

backward synchronously, or moving forward and backward asynchronously, rising

and lowering with limited separation distance (less than 1m). It is convenient for

installing and removing BOP stacks.

II. Type and Specifications

1. FY-50Y BOP Handling System mainly consists of left / right handling devices and

hydraulic system.

2. FY-50Y BOP Handling System is powered by hydraulic power station for floor

mechanical tools (i.e. power tongs) of drilling rig.

3. FY-50Y BOP Handling System is easier to assemble and disassemble. All

hydraulic hoses adopt snap joints (completed with dust-proof plugs or caps) as

connections. It not only makes it easier to assemble and disassemble system but

also keep inner hoses clean.

4. Technical Specifications

e. Max. Horizontal Moving Speed (Dual Direction): 12m/min

f. Max. W.P. Hydraulic System: 16MPa

g. Max. Flow Hydraulic System: 120L/min

h. Wire Line Diameter: 28mm

III. Structure and Features

1. FY-50Y BOP Handling System is combined by two single lifting devices which

each hung on guide rail below the drill floor. One device can lift maximum 250kN

load and 500kN for two.

2. The system adopts 3 times stroke scale-up structure which features with shorter

cylinder stroke, bigger lifting height. Compared with other same lifting height

BOP handling system, it has lighter weight and compact volume.

3. The system is full hydraulic control. Each lifting device consists of following parts:

Running mechanism (powered by hydraulic motor)

Lifting cylinder

Wire rope and pulley block

Main frame connecting running mechanism and cylinder

Hydraulic control system.

4. Operator can operate and control system by hydraulic control box to achieve the

following actions:

Rising and lowering synchronously

Moving forward and backward synchronously

Moving forward and backward asynchronously

Rising and lowering synchronously with limited separation distance (less than 1m)

5. By full hydraulic control, it features higher performance on explosion-proof.

6. Easy operating valves on hydraulic control box make it easy to control the speed

of rising, lowering, moving forward and backward.

7. FY-50Y BOP Handling System is easy to install and transport. All hydraulic hoses

used to connect or disconnect on installation or dismounting adopt snap joints as

connections. It not only makes it easy to install and dismount system but also

keep inner hoses clean.

IV. Installation and Test

1. Infix two lifting devices separately from the ends of guide rails below the drilling

floor (see Figure 2 for installing direction), and mount stop pins on the end of the

guide rails to prevent lifting devices from sliding out of the guide rails.

2. Weld backing plate of pipe hanger matched with wed plates on the middle of

guide rails and mount pipe hanger (see Figure 2).

3. According to the matching codes stamped on the snap joints, connect all

hydraulic hoses with two lifting devices.

4. According to the matching codes stamped on the snap joints, connect all

hydraulic hoses with hydraulic control box and lifting devices, and fix the middle

of hoses on the pipe hanger.

Note: The length of hoses between pipe hanger and lifting device

should meet the requirement of lifting devices on moving forward and

backward.

5. Connect oil inlets and outlets on the hydraulic control box with oil inlets and

outlets on the hydraulic station of power tongs on the drilling floor.

6. Ensure all pipe connections in good condition, start hydraulic station to provide

FY-50Y BOP Handling System with 16MPa hydraulic oil.

7. Push handles of control valves according to the direction marked on the

nameplates of the control box and check if all actions are right. Only after all

actions must be checked with no any mistakes, then the system can be put into

operation.

!!! Caution !!!

On the operation of moving forward and backward asynchronously,

the distance between two lifting devices must be less than one meter,

otherwise it will cause serious accident.

V. Operation, Maintenance and Safety

1. Watch the manometer on the hydraulic control box to check if oil-feeding

pressure meets the requirement (16MPa).

2. According to the directions marked on the nameplates of hydraulic control box,

operate two lifting devices to rise, lower, move forward and backward.

2.1 Synchronously control valve No. 1 and 2 to make system move synchronously.

2.2 Asynchronously control valve No. 1 and 2 to make system move asynchronously.

!!!Caution!!!

On the operation of moving forward and backward asynchronously, the

distance between two lifting devices must be less than one meter,

otherwise it will cause serious accident.

2.3 Synchronously control valve No. 3 and 4 to make system lift synchronously.

2.4 Asynchronously control valve No. 3 and 4 to make system lift asynchronously.

3. Maintenance is the needed procedure before installation of two lifting devices.

There are 8 lubrication ports on the lifting device each, 6 for pulleys and 2 for

driving gears. All lubrication ports should be fed by lithium base grease.

4. Before each lifting operation, operator should check if all cables are in good

conditions. All cables should be reliable connection before operation. On lifting

operation, workers should be far away from the goods to avoid accidents

line from balance valve to cylinder rod cavity. The preset pressure is 19Mpa. In

case that oil drainage occurs upon the security oil vent during operation, which

means oil return line blocked, stop operating at once and check connecting of line

and adapter. Only the line is connected properly can operation be allowed, in

otherwise serious accident is happening!
