Examples of HYDAC solutions 

Following are a few examples of HYDAC equipment on the job.

Backflushing Filters AutoFilt RF3 are used to protect oil and gas pipelines at risk of being flooded with fresh water or seawater.

Bladder and piston accumulators are used on electro-hydraulic actuators for emergency gas pipeline shut-off.   

The Compact Fluid Aqua Mobile FAM unit is used for degassing, dewatering and filtration of hydraulic and lubrication oils.

Radial piston pumps BRK are used in drilling rigs and wellhead control panels WHCP even under rough conditions. They are known for being very robust radial devices with high volumetric efficiency, wide speed range, and high reliability.

ATEX oil-air coolers are used in top drives, hydraulic power units, and lubrication systems.

Condition monitoring

HYDAC’s preventive maintenance increases fluid service life.

Pressure transducers (up to 15,000 psi /1030 bar) in hydraulic power units, wellhead control panels and BOPs are par for the course. They have triple certification in terms of ATEX, CSA, and IECEx (explosion and flame proof).

Offshore applications

HYDAC offers offshore solutions for customer applications such as:

  • Water injection filtration
  • Heave compensation
  • Blowout preventers
  • Davits, A-frames, and cranes

Floating production storage and offloading

One of the first steps in the treatment of water is pre-filtration, followed by fine filtration. This is precisely where the HYDAC solution comes in.

Three AutoFilt RF3 filters with a filtration rating of 50µm are used as coarse filters, and three process inline filters PLF1 are installed further downstream to provide fine filtration to 5µm absolute. In essence, the HYDAC filter solutions used in this type of application serve to protect the high-pressure pumps and membrane system.

Offshore products

Offshore products include the Autofilt RF3, Process Inline Filter PLF1, and hydraulic power unit (HPU). The HPU drives a hydraulic pile hammer for placing foundation piles subsea such as offshore platforms or windmill foundations.

Hydraulic cylinders, ABS-type approved accumulators, and coolers are used for offshore cranes. Cylinders can be painted according to application conditions or regulations and customer-specific requirements.

A filter with hazardous area clogging indicator VDHA with a 316 stainless steel junction box (ATEX and IECEx, CSA/UL indicator approval) can be used on a Wellhead Control Panel. 

The QHP Bladder accumulator is designed and constructed especially for the oil and gas market. Special elastomer, steel materials and connections are available depending on customer requirement.

QHP Piston accumulators are designed for various applications. They come in

various lengths and diameters and can therefore be manufactured to suit individual requirements.

HYDAC components, systems, service, and training

Ball valves, electronics/control technology, mounting technology, pumps, hydraulic cylinders, and coolers are widely used in the oil and gas industry.

Heave compensation systems are used on deck cranes to neutralise the movements of a vessel. No fixed reference point is needed for this process in the case of Active Heave Compensation (AHC). Instead, a Motion Reference Unit (MRU) compensates for the swell by measuring roll, pitch, and yaw motions. This active hydraulic system consists of a piston accumulator and cylinder coupled to each other.

Cranes. To ensure safe and precise loading and unloading of ships HYDAC offers standard hydraulic cylinders adapted to marine conditions as well as customised solutions for deck cranes. Applications include:

  • Special valves on the cylinders help control the movement of the arms and enable precise lifting of loads (can also be supplied with electroplated and sprayed coatings, which enhances cylinder durability)
  • Hydraulic cylinders can withstand a pressure of 400 bar and so are able to lift especially heavy loads


Kinesys

Speed variable multiple pump system DVA-Kit

Features of the variable speed multiple pump system DVA-Kit include:

  • DVA-Kit to supply a central hydraulic system
  • Needs-based pressure control, which turns the DVA-Kits on demand on or off
  • In case of an error the options are to switch the operating mode between two or one pump manual operation

E-cylinder and synchronous servomotor

E-cylinder and synchronous servomotor make for:

  • High dynamic operation
  • Highly accurate positioning controllability
  • Force monitoring and force controlling 
  • Eco-friendliness

Edge computing with KineSys data

Edge computing with KineSys data enable:

  • Connectivity to KineSys drive controller, PLC, and cloud services
  • Visualization of life and historical data
  • Data processing

Components and systems for shipping and mobile power units

HYDAC also provides components systems and service for shipping and mobile power units and for automatic pre-filtration in the treatment of ballast water.


Industry outlook glimpse

Oil and gas extraction industry

The oil and gas extraction industry is projected to grow over the next five years supported by recovering prices and stabilising demand conditions following the COVID-19 pandemic, according to IBISWorld Research.

However, with industry firms reducing capital expenditure and delaying investment in new projects at the height of the outbreak, growth in production capacity is projected to slow over the next five years, the research says. This trend is anticipated to constrain the industry's performance over the period.

HYDAC is a partner you can rely on in oil and gas industry

Oil and gas field services in Australia

Revenue for the oil and gas field services industry is forecast to grow modestly over the next five years, according to IBISWorld research.

Pipeline transport industry in Australia

The pipeline transport industry is forecast to continue expanding over the next five years, according to IBISWorld research.

The industry's role as an intermediary is expected to help protect revenue generated from existing assets despite uncertainty in upstream and downstream industries caused by the COVID-19 pandemic, the research says.

LNG export facilities commenced operations in Queensland from 2015-16, allowing for the international trade of eastern seaboard gas for the first time, the research says. Gas export markets are anticipated to support ongoing demand for gas transportation over the next five years, offsetting limited demand in some traditional domestic markets, such as manufacturing.

Industry revenue is forecast to grow at an annualised 1.5 per cent over the five years through 2026-27, to $4.6 billion. 

Petroleum exploration industry in Australia

The petroleum exploration industry is anticipated to return to growth over the next five years as demand conditions stabilise following the COVID-19 pandemic, according to IBISWorld research.

The world prices of crude oil and natural gas are projected to increase, encouraging firms to explore for new oil and gas reserves. However, uncertainty regarding onshore drilling bans and domestic gas reservation policies may constrain demand for exploration services, the research says.

Industry revenue is forecast to increase at an annualised 5.5 percent over the five years through 2025-26, to $1.3 billion.

Pipeline construction in Australia

The pipeline construction industry is forecast to rebound over the short term due to work on several export-oriented gas pipeline projects in Western Australia and the Timor Sea, according to IBISWorld Research.

Demand for maintenance and upgrade work on existing pipeline networks is projected to underpin the industry's performance over the next five years, including construction work on interconnector pipelines, the research says.

Industry revenue is forecast to increase at an annualised 4.1 percent over the five years through 2025-26, climbing to $1.8 billion. Despite the industry's improved performance, industry activity is forecast to remain at less than one-third of the record peak in 2014-15.
