Andritz’s submersible motor expertise success

In one of many world’s largest oil and gas fields, the firstever underwater compressor system employs ANDRITZ submersible motors. With their renewable winding these maintenance-free designed pumps have achieved spectacular outcomes.
We are surrounded by gasoline. From water bottles to the insulation in our homes, natural fuel is a key ingredient in just about each product we use every day. According to the most recent report issued by the International Gas Union (IGU) in 2019, the global demand in gas has been rising by 35% of the previous decade alone.
เกจแรงดันลม for this pattern are manifold, however the IGU determines three major components. First, the cost competitiveness of gas in distinction to different power sources. Secondly, greater safety of provide with regard to infrastructure, delivery, and versatile use. Thirdly, fuel represents a sustainable form of vitality that may mitigate climate change and lower localized air pollution. It has 50% fewer CO2 emissions compared to coal, for example.
In order to fulfill this rising demand and use, the eco-friendly potential gasoline should be extracted using a sustainable process. One of the largest methods is the Åsgard oil and fuel field on the Haltenbanken, 200 km off the coast of Norway. It accommodates fifty two wells combined in sixteen gas fields and linked by 300 km of oil pipelines. As of December 2018, the sphere has estimated resources of 9.9 million normal cubic meters of oil equal of oil and fifty one.1 million normal cubic meters of oil equal of gas.
The system used contains three important areas: Åsgard A, B, and C. Åsgard A is a floating oil production vessel that has been anchored there completely since extraction began in 1999. Åsgard B is a floating, semi-submersible fuel and condensate processing platform for processing and stabilizing of gasoline and condensate. This platform is supplemented by the condensate storage facility Åsgard C and the 707 km-long Åsgard fuel pipeline to the Karsto processing advanced to the north of Stavanger, Norway.
First on the earth Aker Solutions ASA has been supporting the Åsgard gasoline subject with numerous gas area merchandise, techniques, and services since 2010. In time, the stress in the storage facility in gas-producing fields drops. Compressors are needed to sustain the output. Aker delivered the first-ever underwater compressor system worldwide to Åsgard in order to enhance the output to 306 million barrels. These are usually installed on platforms above sea degree.
However, Åsgard is based on an underwater system. By using compressors on the seabed the recovery charges are improved and the funding and working prices are decreased. In addition, underwater compression leaves a smaller ecological footprint and is extra dependable than a platform. The Åsgard system consists of modules for two identical units of compressors, pumps, scrubbers, and coolers. The motors needed to drive the pumps come from ANDRITZ.
Small, but essential
In 2010, Ritz Pumpenfabrik GmbH in Schwäbisch-Gmünd, Germany, became ANDRITZ Ritz GmbH and a part of the ANDRITZ Group, as did the manufacturing of submersible motors. Due to the renewable winding, ANDRITZ submersible motors are appropriate for driving deep nicely pumps, backside intake pumps, suction pumps, seawater pumps, and underwater machinery.
Depending on the area of software, the motors may be manufactured from cast iron, bronze or different kind of chrome steel and put in either vertically or horizontally. These are water-filled and watercooled, three-phase asynchronous motors with squirrel cages and a mech- anical seal. They are fitted with MCT, a particular cooling expertise. In designs with inside permanent magnet motor technology, or IPM for short, these maintenance-free motors can obtain impressive outputs, efficiencies and, in consequence, price savings.
The effective and measurable motor cooling system retains the interior temp- erature as low as potential. Drinking water is used as a cooling liquid, which is why the motors can function in media of as a lot as 75° C. An impeller with optimized suction and delivery is mounted at the lower shaft finish of the rotor. One of its two major duties is cooling and lubricating the close by thrust bearing. By doing so, the impeller ensures there’s a fixed flow of cooling liquid in the best path.
This liquid strikes by way of the within of the motor from the bottom to the highest. The specifically developed cooling channels define the precise path over all heat sources to discharge the heat successfully and systematically. At the top finish, the heat from the liquid is then discharged by way of the motor’s outer wall. Here, it’s transferred via the surface of the motor to the medium to be pumped.
The ANDRITZ submersible motors are just a tiny a part of the underwater compressor system, however they are also an extremely important half. The whole underwater station cannot function with out these motors to drive the pumps. Since first being put in in 2016, these submersible motors have been operating with none faults. All in all, ANDRITZ Ritz delivered three twopole submersible motors with an output of 736 kw. เกจวัดแรงดัน forms the condensate unit together with the pump and conveys these liquids which may be eliminated by the separator upstream of the fuel compressors.
In 2017, due to a failure in part of the system which was not provided by ANDRITZ, the motor was despatched in for repairs, throughout which an intensive examine was performed. Thermal distribution within the cooling flow and the recent spots had been analyzed in more element. The outcomes also led to the design of a brand new plate crosssection for the rotor plates.
Because of this, the motor to be repaired was additionally fully overhauled and fitted with a model new winding and a brand new rotor. This research and the implementation of its findings not solely benefit the present buyer and future prospects on this case, but additionally strengthen confidence within the ANDRITZ submersible motor technology.
