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.

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
★Warning!
In the hydraulic system, safe overload valve is equipped on the oil

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!
