We are nearly half way through our A-Z of energy alphabet – can you help us with the next letter and win your school one of the latest iPads?
Lauryn Thomson from Mearns Academy was this month’s winner with her description of a jack-up vessel.
Our next letter is K, for kerosene. To get involved all you have to do it tell us about kerosene – what is it, where does it come from, what is it used for and anything else you can find out.
Write it up in no more than 250 of your own words and send your entry to us by Friday, November 23. You could get your entry printed in Energy next month and win your school an iPad, thanks to Shell, which is supporting our A-Z of energy.
Don’t forget to include your name, age and what school you are at.
Shell’s Inside Energy app is packed with information on energy through videos, animations and photo galleries.
Email your entries to elaine.maslin@ajl.co.uk and good luck.
| J for jack up |
|---|
| A jack-up rig is a type of mobile platform that has a buoyant hull fitted with movable legs.It is possible for the hull to lift over the surface of the sea and transport the unit and all of the machinery on the platform to a particular place.How do jack-up rigs work?
The legs of a jack-up rig can be raised or lowered independently of each other and may be designed to penetrate the sea bed. They rest on the sea floor and lift the hull. The main advantage of a jack-up rig is that it can alter its height. Some jack-up rigs are not self-propelled and rely on tugs or heavy lift ships for transportation. Since the first jack-up rig was built in 1954, this type has become the most popular style of mobile offshore drilling unit (MODU) for offshore development purposes. In fact, there are hundreds of offshore jack-up’s around the world performing drilling and work over operations in just about every environment. They are also used in the construction of offshore wind farms. And now for some facts. Jack-up rigs have been the most popular and numerous of various mobile types in existence. The total number of jack-up drilling rigs in operation alone will be about 540 in the end of 2013. By Lauryn Thomson, 12, Mearns Academy |
