Product Definition

Frames hydraulic power units (HPUs) provide reliable and clean

hydraulic energy to a variety of users in offshore and onshore

locations. Our HPUs will reliably operate a range of equipment,

including subsea controls, IWOCS, topside actuated valves, turret

actuated valves, cargo handling systems, turret disconnect systems,

and seal isolation.

Product Description

Frames HPUs provide clean hydraulic power at specified pressure and

flow levels to ensure reliable operation and control of a wide variety

of equipment. The Frames team of experienced engineers works

closely with your business to develop HPUs that match your unique

process conditions, site-specific requirements, local legislation and,

if applicable, third-party requirements, such as Lloyd’s, ABS, DNV

and BV. In addition, our systems are designed to operate in harsh

environments that can vary from extremely cold offshore arctic seas to

extremely hot and dry desert environments.

Frames hydraulic power units are often part of integrated packages

that also comprise other equipment. The main purpose of our HPUs

is to provide hydraulic power to actuated valves. However, in specific

cases our HPUs can be designed to operate quick-disconnect couplings

used on disconnectable turrets or pressurized seal systems.

Product Leaflet / p 1

Frames HPUs generally comprise the following

hydraulic components:

• Enclosure

• Reservoirs

• Motor pump assembly

• Filters

• Accumulators

• Control panel

The selection of components and materials depends

on the required flow and pressure rating, but also on

the type of fluid, as well as environmental conditions.

Enclosure

HPUs assembled by Frames can be housed in a

fully enclosed AISI316 cabinet, or we can choose

an open-skid/rack principle for easy maintenance.

Which enclosure is used depends on the location

in which the HPU is being installed. If required, the

cabinet/skid can be designed, built and certified to

standards such as DNV 2.7-1, ABS, and CE.

Reservoirs

Each Frames HPU is equipped with at least one

main supply reservoir, but in many cases HPUs

include a dedicated return reservoir, especially

when a production environment involves polluted

return fluids.

Motor pump assembly

The pump units selected for our HPUs depend on

the fluid type used, which can vary from mineral

oil, synthetic oil or biodegradables to water/glycol-

based fluids. Pump drives can either be electric or

pneumatic, depending on the available utilities.

Filters

Our hydraulic power units are designed to

guarantee sound operation of the hydraulic

controls in the field downstream from the unit. The

HPUs include filters that maintain the cleanliness

of a system during operation by preventing

contamination of any of its components. All Frames

HPUs are thoroughly flushed before testing.

Hydraulic Power Unit (HPU)


Accumulators

Frames HPUs include either piston or bladder type accumulators

that store the pressurized hydraulic fluid in order to ensure users a

constant hydraulic flow during operation. Accumulators can be selected

in compliance with a variety of standards, including PED, ASME,

AS1210, NR13 or the standard of any of the major certification bodies.

Controls

HPUs are generally controlled by the client’s control system, which is

connected with the client’s MCC and DCS. However, Frames can also

provide plug & play solutions in which our unit only requires a 230-

690 VAC three-phase power supply to automatically operate pumps

and provide feedback signals showing the soundness of the operation.

Feedback signals can be directed to the client’s control room,

significantly reducing interface engineering and cabling.

Materials

The materials used in our units match the specific requirements of our

client’s operational environment, and can therefore include the full

range of exotic materials used in tubing and fittings, but also in valves

and instruments.

Process Description

Frames HPUs are built to continuously meet the varying conditions of

our client’s operational processes. Our HPUs include hydraulic pumps

(single or dual arrangement) that draw hydraulic fluids (mineral oil or

water/glycol) out of a supply reservoir/tank and store hydraulic energy

in a hydraulic accumulator bank. The pumps keep running until the

pressure in the accumulator bank reaches a pre-set pressure level.

Each pump header contains a filter set to ensure the cleanliness of the

hydraulic system.

The pump discharge line is typically equipped with isolation valves,

a check valve and a safety relief valve to protect the system from

overpressurization. When the pressure drops to a pre-set level, the

system reactivates the pumps, and the accumulators are refilled with

fluid by the pumps.

While the accumulators are keeping the system’s pressure at the right

level, a pressure control valve enables the operator to regulate the

hydraulic pressure moving to the actuated valves.

Each pressure section is equipped with automatic and/or manual

control systems, pressure gauges and/or pressure transmitters

to monitor and control the hydraulic pressure at all times. Each

hydraulic pressure line contains bulkhead connectors at the panel’s

sides to connect the actuated valves in the field.

Frames can also include a directional control valve in the HPU pack-

age in case the actuated valves are not supplied with local controls.
