QUU utilise a flow/pressure modulation system management model whereby domestic and commercial water supply reticulation system pressure is increased with a respective increase in system flow demand and conversely pressure is decreased with a decrease in flow demand. This effectively negates pipe friction effects and delivers a relatively constant system pressure independent of flow demand.

The greater Brisbane Council region has a large network of pressure reducing valves. All of these are telemetry directed and flow modulated. Put simply they turn the system’s pressure down when demand is low and turn it up when demand is high.

HMA Geotechnical has supplied its Wisenmeshnet® wireless infrastructure monitoring system for one of the largest industrial projects in Eastern Indonesia. This is the first time that this system, intended mainly for mining and civil engineering, has been adapted successfully for such an application.
The PT PLN (Persero) on behalf of Government of Indonesia is undertaking the Asahan III Hydroelectric Power Plant project in North Sumatra, Indonesia. The project involves the construction of a hydroelectric power plant with a total power generation capacity of 174MW. The project will feature two units of 87MW capacity.

It is all too easy to forget that the primary function of the desalting system is the removal of inorganic chlorides and other water-soluble compounds from crude oil. One need not be a corrosion specialist to realize the acids that form from these compounds can do tremendous, long-term damage in downstream processes of the refinery (as the inspection of crude tower overhead condensers can prove).

Free Water Knock-Outs, Desalters and Dehydrators are just some of the applications in the oil industry where it is necessary to separate water and oil. The density differences between water and oil causes water to drop to the bottom of a separation tank, and oil to rise to the top.

Leakwise Oil Spill and Leak Detection systems are installed in many oil/fuel storage facilities all over the world. The systems are being used in a variety of applications to address health and safety directives, environmental regulations and economic necessity.

The unique capabilities of the Leakwise Oil on Water Monitoring Systems enable remote measurement of oil presence for: Site assessments, Recovery wells and remediation systems, Well closures. The data can be transmitted to remote data loggers or computers via local wired processor or via satellites, cellular, or point-to-point wireless communications.

Hydrocarbon leakage, from Underground Storage Tanks (USTs) and from the bottoms of aboveground tanks, can seep into the groundwater, where it forms a floating oil sheen, growing to a thick oil layer over time. This layer, if left undetected, will eventually dissolve and cause severe damage to water quality.

Storm water accumulated on a concave floating roof of an oil storage tank may affect its floatation, making it necessary to immediately drain the water. This is usually done through a flexible pipe, running from the floating roof down the tank, with an outlet above the ground near the bottom of the tank.

Water may carry oil leaked from turbine bearings and lubricating/cooling systems into deep sumps built under the turbines. In most plants, pumps installed at the bottom of the sump discharge the water directly to the river.

Fuel fired power generation plants have several oil storage tanks for feeding fuel to the power units. Coal or gas fired power generation plants also have oil storage tanks to be used for start-up or as a back-up energy source.

Utilities have hundreds of transformer substations. In each substation, there are usually several transformers. Each transformer contains a high volume of cooling oil.

Pipeline companies install oil collection containments in sensitive locations along the pipeline (e.g. near rivers and/or groundwater drinking wells) for oil leakage monitoring. When an ID-223 Oil Sheen Detector installed in such a containment detects oil or oil on water, it sets off an alarm in a remote location.

Oil is used extensively in all types of transportation. Oil leaks can occur during fueling and maintenance, and also during regular operation.

Often there is a need for quick field measurement of gas condensate concentration in produced water, such as when performing process optimization, water treatment verification, as well as routine process monitoring. Rigorous laboratory analysis methods such as gravimetric oil & grease measurements or gas chromatographic methods are not sufficiently sensitive to process changes and/or do not provide the required quick turnaround.

Aircraft hangar fire detection and protection systems are critical to protect the contents of the hangar and the facility itself. While a regional fixed base operator hangar might price out at $150,000 and a commercial jet airliner hangar at a few million, the commercial or military aircraft inside hangars can easily cost hundreds of millions of dollars.

HMA Wear Solutions has completed a major US$1.5 million contract to manufacture 279 ceramic-lined pipes – including all fasteners, gaskets, and pipe supports – for an upgrade project at the Ombilin power station in remote Sawah Luto in West Sumatra, Indonesia. This ageing power station was experiencing major issues in terms of efficiency – especially in and around its pulverised fuel delivery system, resulting in increased emissions from incomplete combustion.

Hydroelectric dams produce electric power by harnessing the force of the water flowing through the dam. There are numerous sources for oil spillage: The hydroelectric turbines are lubricated by lubrication oils, The very large water control valves are normally hydraulic powered and are lubricated with various greases and oils, Vehicles including fork lifts, trucks, etc, can spill oils and fuels.
