"Making the development of future oil and gas fields in very deep water both possible and economically attractive will require a host of new technologies. Terry Knott learns more about BP’s deepwater technology programme and its role in supporting the company’s leading position in this core business area"
Ask David Brookes – or any member of BP’s deepwater facilities technology team – why BP is committed to driving forward deepwater research and development (R&D), and the answer is clear and unequivocal.
‘Over the next four years, the proportion of oil and gas BP produces from subsea fields around the world is going to more than double,’ he explains. ‘By 2012, we estimate that over half of our field development projects that are likely to be under way by then will be in deep water. Many of these could be in water depths of 2500m, 3000m or even more. If we are to be able to move to such depths and pursue these opportunities economically, we have to be ready with the right technology at the right time. Without this, opportunities may be lost.’

A deep and long cruising range AUV “URASHIMA” has been developing by JAMSTEC since 1998. The sea trials had been started on June 2000, and URASHIMA achieved submarine cruise of 3,518m depth in 2001. The test goal is 300km with fuel cell system in cruising range. URASHIMA can cruise long range distance and collect a lot of seawater sample and oceanic data of various depth. Therefore the vehicle has to shift depth during cruising for exploration. The seawater density is also changed, when the depth is changed. It is necessary to control buoyancy for the energy saving. URASHIMA has buoyancy control system like bladder of fish. In the sea trial, we carried out buoyancy adjustment test and got some useful data. We will show experimental results at the sea trial.
INTRODUCTION Even if the global warming becomes serious problem year by year, we can not elucidate the mechanism of it until now. In order to make clear the mechanism of the global warming, it is necessary to study the global moving process of CO2 in the sea. For this purpose, many geochemical scientist want to gather efficiently a lot of water samples of various sea area and depth all over the world. These missions require the Autonomous Underwater Vehicle (AUV) which cruise long range distance and collects oceanic data and water samples automatically. From this point of view, we started on the research and development project of AUV capable of performing long range missions since 1998.
{mosgoogle}Electrical course is acquired by an individual to improve the skills in the field of electricity. Electrical courses helps in imbibing the knowledge of setting up electricity at a point or repairing a faulty point. Further knowledge in the field can even help in the betterment of electrical technology.
"Artificial Intelligence has been brain-dead since the 1970s." This rather ostentatious remark made by Marvin Minsky co-founder of the world-famous MIT Artificial Intelligence Laboratory, was referring to the fact that researchers have been primarily concerned on small facets of machine intelligence as opposed to looking at the problem as a whole. This article examines the contemporary issues of artificial intelligence (AI) looking at the current status of the AI field together with potent arguments provided by leading experts to illustrate whether AI is an impossible concept to obtain.
As the highly polluted water is drained from the City of New Orleans back into Lake Ponchartrain, it will have to be monitored. In the last few years leading up to the Hurricane Katrina Disaster the Lake had actually been making a strong comeback and had been considered clean enough to fish in or use as drinking water for the neighboring cities with only a little extra filtering. All that has changed now after the many chemical spills, oil spills and human waste in the water that is now known as the Soup Bowl of New Orleans. It will take many years to get Lake Pontchartrain back in order again to the level it was just prior to the devastation from Katrina.
All moving objects create wake or air movement and they cannot help but emit some sound. Can we use the airflow disturbances to detect stealth aircraft by use of laser light plus radar? Thus even though the stealth aircraft would have a minute radar signature nearly undetectable, it would be moving a lot of air. That disturbance would make a unique signature and thus you would know that it is there?
Underwater robots are autonomous underwater vehicles (AUVs). They are usually known as unmanned underwater vehicles in the military and work on specified devices like propellers for propulsion and rudders for controlling the direction of travel under the water's surface. These devices are powered by batteries or fuel cells and can operate in deep water. Most underwater robots use hydraulic batteries because they are more reliable in the deep sea.
How can we keep SmartDust aloft? How can we keep these tiny motes and nodes airborne for long periods of time? It maybe possible to build SmartDust so small you would need to refer to them as nanomites. Carbon Nano Tubes have transparent properties, which keeps them invisible. These nanomites can be built out of carbon nano tubes with water molecules for propulsion. Water molecules display some really interesting properties inside nano tubes and can produce hurricane like forces in a micro scale and transport them selves via micro extreme weather. Kind of like a Tornado lifting and flying a cow?

1. Introduction
In order to explore the vaguely understood, wide and deep underwater environment, which covers two thirds of our planet, it is necessary to navigate to different locations [4]. {mosgoogle}The importance of underwater exploration lies on the fact that the underwater environment is rich with hard mineral and renewable resources, and oil/gas reserves.
