Design PhilosophySubsea actuators series OFO were

developed by BIFFI in the 70s, to be

originally employed in ship construction

to operate valves for oil loading and ship

balancing. OFO actuators are designed

for maximum operation reliability in

submerged crude oil or sea water

environments, and are especially suitable

for quarter-turn valves.

Subsea actuators requirements

- Maximum operating reliability

- Easy installation and disassembling

without need for any special

frame/device

- Sturdiness and compactness

- Long operating life

A rack and pinion mechanism was

selected because of these requirements.

The spool piece allows quick and safe

underwater installation and removal of

the actuator. Perfect alignment of the

valve shaft is not vital and there is noneed for a special frame to facilitate

installation.

Considerable thought and care were

given to the selection of materials,

manufacturing, assembly and tests. OFO

actuators satisfy the strictest

requirements for strength and long life.

Construction materials

The choice of materials for the housing of

OFO and OFOS actuators was made

after long and severe tests. Several studies

and considerations brought to the final

selection of cast iron A536 60-40-18 with

an additional content of 3% Ni for the

following external actuators parts:

- Actuator frame and cover

- Pressure equaliser

- Mechanical position indicator

The body of the hydraulic cylinder is in

ASTM A439 D2C, that is, austenitic iron

with high nickel content (up to 20%) and

the following properties:- Good resistance to general corrosion

and particularly to pitting in calm sea

water

- No graphitic corrosion

- Low friction factor to ensure adequate

actuator operation.

The actuator internal parts are in

stainless steel AISI 420 and SAF 2205.

Main bolting is in Teflon-covered alloy

steel ASTM A193 B7.


To avoid all sticking effect, the the

O-rings of the dynamic seals have the

relevant back-up ring type step seal

made in Teflon).

In addition, the nickel chromium alloyactive metal and ASTM A439 D2C cast

iron have the same galvanic corrosion

potential: this avoids all galvanic effect

between the two main materials of the

actuator.

DesignParticular attention was given actuator

compactness. There are no pipings or

fittings on the actuator, according to amanifold concept.

The cylinders are directly fed by the

hydraulic manifold and through holes

machined in the housing. For the sake

of compactness, integral pressure

equalisers are made of the same

material as the actuator.

The external surface of the actuator is

painted to Customers specification.

Cleanliness

After assembly, the actuator is flushed

with the same fluid used for fieldoperations. Cleaning grade is usually

referred to international standards such

as NAS 1638 class 6.

Actuator description

OFO and OFOS hydraulic double- and

single-acting subsea actuators are

equipped with a rack and pinion

mechanism and plunger-type pistons.

They are available in the following

configurations:

- Double acting, with two cylinder

- Double acting, with four hydraulic

cylinders- Single acting, with a cylinder and a

spring cartridge

- Single acting, with two cylinders and

two spring cartridges

The actuator may be fitted with several

different control systems, according to

customer requirements.

OFO and OFOS actuators can be

installed at any depth under sea level

and are complete with a diaphragm

pressure equaliser. In this way the

internal pressure is equal to the static

pressure at installation depth.

OFO and OFOS actuators can be

equipped with additional gear and ROV

interface for emergency valve stroking.

Spool piece

The actuator is connected to the valve

by means of a special spool piece. The

actuator is fastened to the spool piece

by means of two locking handles, easily

accessible and located on top of the

actuator. During actuator mounting, the

last 100 mm between the actuator and

the spool piece are guided by means of

a dowel taper pin.

Mounting of the actuator on the spool

piece is possible regardless of the valve

position.

The spring cartridge of single-acting

actuators is also filled with oil or

biodegradable water-based fluid, and is

connected to the actuator housing.

On request, the actuator equalisation

device can be of the open type, utilising

Nemis oil as actuator filling fluid.

OFO/OFOS actuators are also equipped

with:

1 - Tactile/visual local position indicator

2 - Stainless steel relief valve (for internal

overpressure)

3 - Adjustable mechanical stop on the

cylinders

4 - When the spod piece is used, the

following features are also available:

Note:

The valve actuator coupling system

allows to perform the actuator/valve

diagnosis by disconnecting the actuator

coupling from the valve stem adaptor

without removing the actuator. Therefore

the actuator can be stroked without

moving the valve, thus allowingfunctional check of the actuator itself.



2

- Visual local clutching indicator- Automatic spring-actuated clutch

for quick coupling to the spool piece

- Different-size square spigot for torque

transmission and positive actuator

position


5/24



3

The lower flange of the spool piece is

specifically designed to comply with the

requirements of the different valve

manufacturers. The coupling andfastening quickness, allows to use a

single actuator for several valves,

providing they are equipped with the

same spool piece.

The spool piece is complete with:

- adjustable mechanical stops. These

are set during actuator/valve assembly

(before immersion) and allow to remove

and replace the submerged actuator

with no need for further resetting

- electric limit switches (optional)

- relief valve to prevent internal

overpressure (in case of leakage

through the valve stem)

- drain valve for internal flushing

- protection cover, installed on the spoolpiece after actuator removal. The cover

is equipped with a tactile/visual

position indicator.

The spool piece can also be supplied in

a pressure retaining version.

The actuator and the spool piece

arrangement can accommodate valve

shafts with acceptable misalignment of

10 degrees from vertical and 3 degrees

from horizontal.

OFOS SPRING RETURN CONTROL

APPLICATION EXAMPLES

- REMOTE CONTROL

Open operation

Pressurizing port (5) the dump valve

closes return line (6) and the actuator

piston compresses the spring and

opens the valve. The oil displacement

due to the piston in the spr ing

enclosure flows into return line (6) to the

power unit on surface

Close operation

When the oil pressure on port (5) fails

the dump valve trips and causes thespring to move the actuator to close

postion. Operating speed is controlled

by the orifice (4). From port (6) the oil

flows back into the spring enclosure to

recover piston oil displacement

Supply line flushing

Connect oil receiver bag to port (10)

Close stop valve (8)

Send pressure to connection (5) and

open stop valve (9)

Partial 10% close operation

Depressurinzing supply line port (5) will

cause the actuator to move in closing

and actuate the limit switch located at

10 from the open position

Repressurinzing supply line port (5) will

cause the actuator to move to fully

open position

- REMOTE CONTROL [Valve (4) in position R]

Open operation

Pressurizing port (5) dump valve (7)

closes the exhaust port and the actuator

piston compresses the spring and

opens the main valve.

Close operation

When the supply pressure decreases orfails, dump valve (7) opens the exhaust

port and the spring brings the actuator

back to the closed position. Operational

speed fails the dump valve trips and

causes the spring to move the actuator

to close postion. Operating speed is

controlled by the orifice (8).

- LOCAL CONTROL [Valve (4) in position D]

Open operation

When diver hot line pressurizes port (6)

the actuator piston compresses the

spring and opens the main valve

Close operation

Port (5) with pressure: diver must be
