Vibration analysis leading into diagnosis (valid) approach

Jyoti K Sinha

School of Mechanical, Aerospace and Civil Engineering (MACE), The University of Manchester, UK

Vibration-based Condition Monitoring (VCM) is generally used in industries to predict fault(s) at early stage in any machine so that the maintenance can be performed before any catastrophic failure. However the question always arises whether the VCM alone in a machine is enough? Answer is generally yes if the failure is not frequent and premature. But if the failure is premature and frequent then the experience shows that the routine VCM alone may not be sufficient. For such cases, it is observed that the dynamics of the complete machine unit comprises of the rotor, bearings and foundation is responsible for such premature and frequent failure. Hence additional tests and analysis are required to understand the machine dynamic behavior which can then leads to solution. The topic will discuss few industrial case studies to show the usefulness of valid approach.

Performance evaluation of swell packers under actual field conditions

Sayyad Zahid Qamar

Sultan Qaboos University, Oman

Swelling elastomers are a relatively recent breed of advanced polymers, known for their self-healing and large stretch when in contact with certain fluids. They undergo dynamic swelling when exposed to water or oil. They have found extensive use as sealing elements and swell-packers in different petroleum drilling and development operations. Swellable elastomer packers (SEP) consist of swelling elastomer sections bonded to petroleum pipes. Many mature fields (which account for more than two-thirds of the worldʼs oil and gas production) have been traditionally abandoned after serious production declines, because of the difficulties and large cost associated with rework. Swell packers have now been successfully employed for workovers, sidetracks, and redrills, putting abandoned wells back into production. When oilfields are producing substantial amounts of unwanted water or gas, increased recovery from maturing reservoirs is possible through shut-off of unwanted water and gas by the deployment of swelling elastomer sections to segment horizontal wells. Swellable elastomers have also been successfully used for cementless completions, for well completion together with cement jobs, and for zonal isolation in openhole completion of foam-drilled horizontal wells.

No studies have been reported about the long-term durability or expected service life of swell packers under actual well conditions. A full-scale test rig has been designed, constructed, and commissioned at Sultan Qaboos University (SQU), Muscat, Oman for five-year long in-situ evaluation of various types of swell packers. This longevity testing of water-swelling and oil-swelling elastomer packers of different sizers is being carried out in partnership with a regional petroleum development company. These packers consist of different types of water-swelling and oil-swelling materials, and are exposed to actual crude oil or brine solutions of different salinities, and are tested at both room and higher temperatures. High differential pressures are applied on selected packers once they have sealed. Elastomer types, swelling media, test temperatures and pressures, all represent actual field conditions in regional oil wells.

Use of Polyurea as a protective coating: New applications of polymers in damage mitigation

Damith Mohotti

School of Civil Engineering, University of Sydney, Australia

The economical and technical values of elastomers in many different industrial applications are still under estimated. Over the last few decades, many researchers have investigated the use of elastomers such as polyurea as a protective coating material due to its ability to absorb a considerably high amount of energy compared to most other similar coating materials. Polyurea uses by products of petroleum industry and has been identified as a good candidate material to use as a protective coating or an energy absorber. In recent years, researchers have drawn their attention towards the application of polyuria to enhance the resistance of structures and systems against extreme impulsive loadings such as blasts. With adequate surface preparation, polyurea bonds well with most structural materials (such as concrete, steel and aluminium), thereby forming composite behaviour. It can be used either as the outer face of a structure, or as an interlayer material, by utilising its compressive or tensile properties depending upon the nature of the load transmitted. Due to the complex nature of its microstructure, polyuria shows a high level of stress–strain non-linearity, rate sensitivity, and a high degree of pressure dependency compared to other elastomeric materials. In addition, polyurea has a higher energy density than most other elastomeric materials. In recent years, a spray-in-place methodology has been introduced for polyuria coating, which has increased its usage in many industrial applications such as tank liners, manhole and tunnel coatings, and secondary coatings on bridges, roofs and parking decks. Recent studies show that it also possesses the desired characteristics for effective protective coating application against blast and ballistic loadings in both vehicles and ground structures. In this presentation, some previous research projects done on polyuria applications on damage mitigation will be reviewed. Also new technological developments possible in polymer industry with their economical benefits will be discussed.

Dr. Mohotti has developed expertise in many interrelated areas in structural and materials engineering including extreme loadings on structures (blast and impact), wind loadings on buildings and development of smart materials. He is considered as an expert in advanced numerical simulations with his immense contribution to the development of this sector. In addition to his expertise as a researcher he has gained worthy of experience working as a structural engineer and a consultant. Dr. Damith is currently working as a lecturer in the School of Civil Engineering at the Faculty of Engineering and IT at University of Sydney. He currently works as a member of the industrial engagement committee of the school and hold the responsibility of delivering three key units of studies on design of concrete and pre-stressed concrete structures.

Fueling our future

The efficient and safe decomposition of formic acid as a promising energy carrier has become increasingly important. We have developed ruthenium based catalysts containing unique ligands for the selective decomposition of formic acid to H2 and CO2 in water in the absence of any organic additives. A turnover frequency (TOF) up to 12,000 h-1 and a turnover number (TON) of 350,000~1,100,000 at 90 °C were achieved. Efficient production of high-pressure gas of 24.0 MPa (3480 psi) without the formation of CO, was demonstrated. A prototype model car was built.
