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: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
