Fundamental to this is the need to accurately know or determine the available ampacity of high voltage cable circuits, because huge bulk power volumes need to be transmitted between maritime nations through dc power cables. Therefore, an accurate cable rating becomes paramount towards an efficient and safe operation of transmission networks, while the finance for large scale network construction schemes is limited. Although the standardised thermal-limited rating has been successfully implemented for traditional ac cable networks for over 50 years, the move towards dc cable transmission imposes extra physical constraints on the cable rating, which are not considered by standard rating approaches. The two main concerns are the potential dielectric electrical breakdown prior to a normal thermal runaway and the development of dielectric cavities during cable cooling. In addition, the thermal- limited rating of submarine dc cable crossings, within a complex marine environment, requires an advanced numerical modelling method, where the traditional IEC thermal-limited rating method does not apply. Besides the technical value, significant interest exists both within the electrical power industry and organizations such as Cigré and IEC, because this work will inform future international standards for rating high voltage dc cables. Considering the dielectric electrical stress constraint as the limiting factor for cable ratings, an analytical electrical stress-limited rating method has been developed and successfully benchmarked by numerical simulations for a practical cable design. This method allows ratings to be calculated against a criterion of maximum dielectric electrical strength. Considering the dielectric cavity creation threshold as the limiting factor for cable ratings, a comprehensive study has been conducted, including thermal dynamics, theory of elasticity and electrical circuit theory. Subsequently, the analytical calculation of the cable internal pressure has been originally developed, together with a concept of the mechanical pressure-limited rating. The i method has been successfully demonstrated for a practical cable design, yielding a rating which prevents the creation of cavity due to potential plastic deformations of the cable sheath. When crossings are inevitably installed, cables are pushed towards their thermal limit, as a result of the mutual heating. In order to accurately rate these circuits under various ambient conditions; Finite Element Analysis (FEA) methods have been developed. Compared to the traditional IEC calculation, FEA modelling provides a more reasonable and accurate solution, by releasing idealistic assumptions in the IEC method. In addition, a systematic cable rating strategy has been suggested and successfully demonstrated through rating submarine high voltage dc cable crossings, which considers highly coupled physics: thermal, electrical and mechanical. In summary, this thesis contributes towards the modern rating methodology development for hvdc mass impregnated cable circuits, under a purpose of efficient and reliable long-term operation. ii

  • Subsea Controls Project References
    SUBSEA CONTROLS PROJECT REFERENCES INTRODUCTION Proserv has been manufacturing control systems in the UK since 1976 and has considerable experience in subsea production system engineering and subsea control system design. As the industry technology has advanced into locating much of the production equipment on the seabed so Proserv has developed control, monitoring and safety shutdown systems which are able to operate in this equipment either from the surface, or the subsea environment. Early involvement in the Subsea arena began for Proserv in the 1980’s with the design and prototype manufacture of our own subsea control module, using our in-house spool-type control valves. These whilst initially adapted and evaluated for subsea use did not show the degree of durability of the carbide shear seal type valves used in our subsea control systems today. A number of subsea hydraulic systems for short step-outs and SSIV controls were made, but it was the development of our Wellcon multiplexed electronic programmable control modules employing shear-seal valves that established Proserv presence in the subsea market. In 1992 our first complete multiplexed Electro-Hydraulic subsea control system was developed and the first full system deployed the following year. In 1999 the Artemis subsea control system was developed adding deep water ROV deployment to the product line. The inclusion of the Sicom OCC modem technology in 2007 enabled open and high performance subsea network availability. In 2014 Proserv launch the latest generation subsea electronics Artemis 2G (A2G) which provides operators with a reliable, more accessible and flexible system with increase data and power performance and full compliance with latest SIIS, IWIS, ISO and API specifications With much more reliance on oil and gas field life extension and brownfield expansion of older field the Artemis and A2G technology from Proserv now provides an alternative to using the original Equipment Manufacture with the Augmented Controls Technology (ACT) provided by Proserv subsea controls technology.

  • Council Award Ceremonies
    www.taxpayersalliance.com Research Note 94 30 September 2011 Council Award Ceremonies With pressure on the budgets of local authorities and council tax having doubled over the past decade, councils need to do all they can to control unnecessary spending and deliver better value for money. While councils should look to recognise strong performance by staff, one area of waste that has been anecdotally reported is excessive spending on award ceremonies. The TaxPayers‟ Alliance has compiled the first systematic list of award ceremonies hosted or attended by councils across the UK during the financial year 2010-11. This research reveals that the ceremonies are often lavish and attendance costs thousands of pounds. Our findings show that councils held ceremonies to present awards for things like “staff graduations”. In addition to buying tickets for them, they also often pay for accommodation, travel and catering. Other local authorities spent no money attending award ceremonies. The key findings of this research are: . Among the ceremonies attended were the Everything Happens Somewhere Awards 2010; the E-wellbeing Good Housekeeping Awards; the Green Apple Awards; Loo of the Year awards and the Kettering K Factor. Councils spent at least £1.2 million on hosting and attending award ceremonies during 2010-11. This is almost certainly an underestimate as many councils could not tell us how much they spent on award ceremonies last year. Glasgow City Council spent the most hosting and attending award ceremonies, at a total cost of almost £83,000. Fife Council attended and hosted the most ceremonies with a total of 34.
