Watertight solution for high risk of flooding

Added - 29.11.2021

AUMA SA-UW actuators for continuous underwater use secure operation of underground emergency roller gates in the city of Doha, Qatar, even when flooded for extended periods of time.
Ashghal, the Public Works Authority of Qatar, decided in the context of a project to extend the E-Ring road in Doha to also upgrade the stormwater network. Several huge roller gates were installed in underground chambers in order to be able to shut off DN 2700 stormwater pipelines in case of emergency.
The actuators to operate the huge roller gates had to be installed inside the chambers. As the chambers may become flooded during heavy rainfall, Ashghal was looking for actuators that can be immersed in water for extended periods of time. The total chamber height is 24.5 m, and the actuators had to be mounted approximately 6 m below ground level.
AUMA supplied powerful SA 30.1-UW underwater actuators that are suited for continuous underwater use at up to 15 m head of water. While the actuators were mounted on an access platform inside the chamber, the AC 01.2 actuator controls were mounted separately from the actuator outside the floodable area using a wall bracket. All local operations can therefore be done safely and from a comfortable position using the AC 01.2 actuator controls.
AUMA SA-UW actuators for continuous underwater use possess a sophisticated sealing system combined with excellent corrosion protection. Double sealed cable glands at the electrical connection, inner seals at all housing covers, and a solid shaft made of stainless steel safely prevent any ingress of water.

AUMA wins five-year contract for Transalpine oil pipeline

Added - 16.11.2021

The Transalpine Pipeline (TAL) connecting Italy, Austria, Germany and the Czech Republic relies on AUMA actuators for the safe and reliable transport of crude oil. 

AUMA has been awarded a framework agreement covering the replacement of existing valve actuators with its proven SAEx 25.1 actuators. As part of the five-year agreement, the AUMA actuators will be installed in the pumping stations along the Austrian part of the pipeline. The first set of SAEx 25.1 actuators has been installed and commissioned. 

The TAL network is 753 km long, linking the port of Trieste in Italy with eight refineries in Central Europe. Handling approximately 40 million tons of crude oil per year, the pipeline plays a major role in meeting the oil needs of Austria (90%), the Czech Republic (50%) and southern Germany (100%). The 40-in. pipeline runs underground for most of its length. It goes through towns and cities, farmland, rivers and lakes, climbing to 1,572 metres above sea level as it crosses the Alps.

Product reliability was a key point in the decision on the actuator brand for TAL Austria because disruptions in the operation of the pipeline would quickly become critical. AUMA’s robust and powerful SAEx 25.1 actuators proved to be a perfect fit, offering a proven track record of several decades in oil and gas applications. In combination with gearboxes, the actuators will provide torques up to 10.800 Nm to automate 40-in. gate valves at differential pressures of 30 bar. 

Local service and support was another key factor for TAL Austria. AUMA service engineers at the company’s Austrian subsidiary can provide fast and competent service at all times, ensuring safe and reliable operation of the facilities. The AUMA contract also includes on-site commissioning and training.

AUMA Supplies Electric Actuators to Award-Winning Singapore Desalination Plant

Added - 04.11.2021

AUMA has supplied more than 150 electric actuators to Singapore’s new Keppel Marina East Desalination Plant (KMEDP), an award-winning plant that was selected ‘Desalination Plant of the Year’ at the Global Water Awards 2021.

KMEDP is Singapore’s first large-scale, dual-mode desalination plant, designed to treat both seawater and rainwater. Due to frequent dry spells and limited land area to catch and store the rainwater, desalination is increasingly important to the island state. KMEDP gives Singapore an important weather-independent water supply, with a capacity of 137,000 cubic metres (36 million gallons) per day.

The award-winning plant uses state-of-the-art technologies to increase its energy efficiency and reduce its environmental impact. The plant’s 20,000 square metre green rooftop provides a park and recreational area. The treatment facilities and pumping station are located underground.

A total of 156 AUMA SA multi-turn and SQ part-turn actuators with intelligent AC 01.2 actuator controls have been installed throughout the different treatment steps of the desalination plant.

At the design stage, PUB, Singapore’s national water authority, was concerned that a large number of actuators would be installed in hard-to-access areas. AUMA, which had already cooperated with PUB on numerous projects in the past, put forward the benefits of its actuators’ modular design. The ability to mount the actuator controls separately from the actuator if necessary, and to orient the display to suit different mounting positions, perfectly met PUB’s requirements.

After sales services with timely on-site support whenever needed was also a critical factor for Keppel Infrastructure, which has a 25-year Design, Build, Own and Operate (DBOO) concession for the plant.

“The AUMA service team is also supporting another business unit of Keppel for the Senoko Waste to Energy Plant, where AUMA Singapore has a servicing and maintenance contract,” says Stefan Kolbe, Sales Director Southeast Asia at AUMA. “Our track record of timely support and technical know-how convinced Keppel that they can depend on us for any issues.”

Actuator Upgrade at Great Billing Sewage Treatment Works for Anglian Water

Added - 13.10.2021

AUMA Actuators Limited (AUMA UK) has successfully completed an actuator upgrade programme across a range of inlet and outlet penstocks at Great Billing Sewage Treatment Works as part of its Service Level Agreement with Anglian Water Services Limited. 

Great Billing Sewage Treatment Works is situated a few miles to the east of Northampton and is operated by Anglian Water Services Limited. It is designated as a sludge treatment centre and receives imported sludge from other sewage treatment works (STWs) in the area for treatment, in addition to treating the sludge produced by the on-site processes.

Existing inlet actuators from inlet penstocks 1 - 4 were decommissioned and removed and AUMA’s SA14.2 AC01.2 actuators were installed mechanically to in situ penstocks. In addition, AUMA fitted remote AC01.2 control heads to wall brackets mounted to the penstock frames electrical power, providing an improved operating position and enhanced view of displays. 

Controls were reconnected to the four actuators by AUMA electricians. Local isolation was added using the unique AUMA plug/socket connector with an integrated electrical isolator. Umbilical cable sets between the actuators and the controls were factory pre-produced in AUMA’s UK factory to minimise site time.

Hand operated gearboxes and shafts were also removed from outlet penstocks 1 - 4 and AUMA UK’s SA14.2 AC01.2 actuators were installed mechanically to in situ penstocks with bespoke adaption plates designed by AUMA UK. Remote AC01.2 control heads were fitted to wall brackets mounted to penstock frames (terminal heads were also supplied with isolators built-in). Umbilical cable sets were installed between controls and the actuator gearboxes.

NICEIC minor works certificates to sign off the power connections to the inlet penstocks were produced by AUMA UK fully employed electricians. Installed actuators were set up and commissioned by AUMA UK’s field service engineers.

Graeme Blair is Maintenance Support Technician at Anglian Water Services Limited. He says: “We’re delighted with the work carried out by AUMA UK at Great Billing Sewage Treatment Works. Within just three days the AUMA engineers removed and upgraded the existing actuators, with everything installed smoothly and without any issues.”

Colin Borrows, Operations Manager, AUMA UK, adds: “This is another great retrofit job. It demonstrates excellent use of our remote mounted controls and the three-phase isolator built into the customer side terminal heads.”

Since being awarded a sole actuator supply framework in October 2019, AUMA UK has worked with Anglian Water to develop a new and unique process to service, maintain and replace a range of actuators throughout the region.
