Land-based checks of offshore machinery

16.08.2007
SINTEF is in the process of developing a sensor that is capable of registering abnormal vibration patterns in machinery on board offshore platforms.

SINTEF is collaborating in the Wivib research project with ABB and SKF to develop the vibration sensor that can be installed, for example, on machinery that drives pumps. Abnormal vibrations may be a sign that a machine is in the process of breaking down.

The sensor is initially intended to be used on offshore platform machinery, and will be installed as a package comprising battery, antenna and circuit board.

Shore-based monitoring

“Together, these components will give us a sensor node that can communicate wirelessly with other sensor nodes and with a central unit. This makes it possible to remain onshore and follow up individual machines hundreds of kilometres offshore,” explains Maaike Taklo, who works at SINTEF ICT’s MiNaLab.

“At present, oil companies are forced to send personnel out to the platform to test machines one at a time, unless fixed sensors have been cabled up.”

Microsystem technology

The sensor nodes need to be cost-effective, so it is an advantage to make use of microsystem technology that tends to make mass production advantageous. The scientists are working on silicon wafers on which a large number of sensor chips are simultaneously, one layer at a time. Instead of laying a “cover” on each individual chip, a glass disc is attached to the upper and lower surfaces of all the chips at the same time, before the disc is cut into individual chips.

The sensors and the wireless communication unit have been tested, and the results are very promising.

“If the balls in a ball bearing are faulty, they generate a high-frequency ringing noise, while machines produce a low-frequency thumping sound with other types of wear. The new sensor is capable of measuring both types of sound simultaneously,” says Taklo.

The project, which goes by the name of Vivib, is financially supported by the Research Council of Norway through its PETROMAKS Programme, which is aimed at the petroleum industry. SINTEF is responsible for supplying the sensor chips, while ABB and SKF are responsible for the wireless communication system and the interpretation of the vibration signals. The project started in 2006 and will continue until the end of 2008. Several oil companies including BP are members of the consortium that is helping to finance the project.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...

Im Focus: Cold molecules on collision course

Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.

How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...

Im Focus: Shrinking the proton again!

Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.

It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
