Andritz’s submersible motor know-how 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 results.
We are surrounded by fuel. From water bottles to the insulation in our houses, natural gasoline is a key ingredient in virtually each product we use every day. According to the newest 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.
The causes for this development are manifold, but the IGU determines three major elements. First, the fee competitiveness of fuel in contrast to different power sources. Secondly, larger safety of supply with regard to infrastructure, delivery, and versatile use. Thirdly, gasoline represents a sustainable type of energy that may mitigate climate change and lower localized pollution. It has 50% fewer CO2 emissions compared to coal, for example.
In order to meet this growing demand and use, the eco-friendly potential fuel will have to be extracted utilizing a sustainable process. One of the most important methods is the Åsgard oil and gas field on the Haltenbanken, 200 km off the coast of Norway. It accommodates 52 wells combined in 16 fuel fields and linked by 300 km of oil pipelines. As of December 2018, the sector has estimated assets of 9.9 million normal cubic meters of oil equivalent of oil and 51.1 million normal cubic meters of oil equivalent of gasoline.
The system used contains three essential areas: Åsgard A, B, and C. Åsgard A is a floating oil manufacturing vessel that has been anchored there completely since extraction started in 1999. Åsgard B is a floating, semi-submersible gas and condensate processing platform for processing and stabilizing of fuel and condensate. This platform is supplemented by the condensate storage facility Åsgard C and the 707 km-long Åsgard gasoline pipeline to the Karsto processing complicated to the north of Stavanger, Norway.
First on the earth Aker Solutions ASA has been supporting the Åsgard gas field with various gasoline area products, systems, and companies since 2010. In time, the strain in the storage facility in gas-producing fields drops. Compressors are wanted to maintain the output. Aker delivered the first-ever underwater compressor system worldwide to Åsgard so as to increase the output to 306 million barrels. These are usually put in on platforms above sea stage.
However, Åsgard relies on an underwater system. By utilizing compressors on the seabed the restoration rates are improved and the investment and operating prices are reduced. In addition, underwater compression leaves a smaller ecological footprint and is extra dependable than a platform. The Åsgard system consists of modules for two similar units of compressors, pumps, scrubbers, and coolers. The motors needed to drive the pumps come from ANDRITZ.
Small, but important
In 2010, Ritz Pumpenfabrik GmbH in Schwäbisch-Gmünd, Germany, grew to become 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, bottom consumption pumps, suction pumps, seawater pumps, and underwater equipment.
Depending on the realm of utility, the motors can be manufactured from forged iron, bronze or totally different kind of stainless steel and installed both 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 everlasting magnet motor technology, or IPM for brief, these maintenance-free motors can obtain impressive outputs, efficiencies and, as a result, price financial savings.
The effective and measurable motor cooling system keeps the inside temp- erature as little as potential. Drinking water is used as a cooling liquid, which is why the motors can function in media of up to 75° C. An impeller with optimized suction and delivery is mounted on the decrease shaft end of the rotor. One of its two primary tasks is cooling and lubricating the close by thrust bearing. By doing so, the impeller ensures there is a constant move of cooling liquid in the right direction.
This liquid strikes via the inside of the motor from the underside to the top. The specially developed cooling channels define the exact path over all heat sources to discharge the heat effectively and systematically. At the top end, the heat from the liquid is then discharged through the motor’s outer wall. Here, it’s transferred by way of the floor of the motor to the medium to be pumped.
เกจวัดแรงดันเครื่องกรองน้ำ are just a tiny part of the underwater compressor system, however they’re also an especially important part. The entire underwater station can not function without these motors to drive the pumps. Since first being installed in 2016, these submersible motors have been working without any faults. All in all, ANDRITZ Ritz delivered three twopole submersible motors with an output of 736 kw. The motor varieties the condensate unit together with the pump and conveys those liquids which would possibly be eliminated by the separator upstream of the gasoline compressors.
In 2017, as a result of a failure in part of the system which was not provided by ANDRITZ, the motor was despatched in for repairs, during which an intensive study was carried out. Thermal distribution in the cooling circulate and the recent spots have been analyzed in more element. The outcomes also led to the design of a new plate crosssection for the rotor plates.
Because of this, the motor to be repaired was also completely overhauled and fitted with a brand new winding and a brand new rotor. This research and the implementation of its findings not only benefit the present customer and future clients in this case, but additionally strengthen confidence within the ANDRITZ submersible motor expertise.
