Horn Online - Classement des Compagnies Pétrolières 2012 | FB BOURSE.COM. La compagnie pétroliére norvégienne: Statoil Classement 2012 des Compagnies Pétrolières et Gazières Le classement 2012 des Compagnies Pétrolières et Gazières, est comme l’année précédente disponible selon trois critères : par capitalisations boursières au 04/05/12, par Chiffres d’affaires, puis par Résultat net réalisé sur l’exercice 2011. Les cours du pétrole élevés sur l’exercice 2011 ont permis aux différentes compagnies d’affichées d’excellentes performances. Le palmarès 2012 montre encore l’importante domination de la compagnie pétrolière américaine Exxon Mobil, 1ere du classement par capitalisation, 2éme au niveau du CA et de la rentabilité. (Comme chaque année, nos trois classements se basent uniquement sur les compagnies pétrolières cotées en bourse.

Rocket anchor holds offshore oil platforms tight. As the world’s supplies of “easy oil” run lower, oil companies are increasingly pursuing the hard-to-get stuff in deep and far-offshore locations. BP’s recently discovered Tiber field in the Gulf of Mexico, for example, lies 250 miles offshore, under more than 1,200 metres of water and 10,685 metres of seabed.
Keeping a drilling platform in place over such a well is a difficult and costly engineering feat, but a Norwegian entrepreneur says he’s developed an easier way to anchor down these installations … with the Deep Penetrating Anchor. Looking more like a space rocket than a typical anchor, the Deep Penetrating Anchor is 13 metres long and weighs 80 tonnes.
The anchor works by being lowered into the ocean, then allowed to pick up speed in a free fall so it generates enough momentum to deeply pierce the seabed, creating a sturdy grip for the platform above. “I believe that we can make our mark in the competition to supply mooring system, in terms of both price and robustness,” Lieng said. Ultra-Deep Subsea Market to Reach $377 Billion Per Year by 2018 - Industry Tap. Engineers are uniquely challenged when working beneath the ocean surface, especially on oil & gas projects. These ocean-based projects require subsea infrastructure, pipelines, floating facilities, flexible and rigid pipe lay and risers, and subsea controls for separation and storage of product. Auxiliary services include integrity management, inspection, repair, maintenance, surveying, upgrading and decommissioning.
Subsea projects range from a few feet deep in marshlands to over 20,000 feet in deep seas, with the overall trend toward deeper and deeper sites located further and further from shore. Equipment Needed for Subsea Work For major players in subsea construction, a fleet of vessels, pipe laying platforms, and subsea cranes are needed to be successful in increasingly demanding ocean environments. The largest consumer of these services is the offshore oil and gas industry; the top five operators are Shell, British Petroleum, Chevron, Apache and Anadarko Petroleum.

Interactive video: Deep sea mining. 14 March 2013Last updated at 08:20 ET Companies are planning to extract minerals from areas of hydrothermal vents, deep on the seabed. The BBC's Science Editor David Shukman explains the process and environmental concerns. Click on the hotspots which appear in this video to find out more. This interactive content is best viewed on the desktop site. X Hydrothermal vents are fissures on the seabed where water penetrates the Earth's crust and is heated to extreme temperatures by geological activity. Specialist organisms have adapted to cope with extreme conditions at the vents, where life depends on chemosynthesis: conversion of chemicals to energy, rather than photosynthesis. Japanese Govt. to subsidize robotic deep-sea mining research - POLITICAL ECONOMY. India joins deep sea mining race | Environment.
India has joined the race to explore and develop deep-sea mining for rare earth elements — further complicating the geopolitics surrounding untapped sources of valuable minerals beneath the oceans. The country is building a rare-earth mineral processing plant in the east coast state of Orissa and it is spending around US$135 million to buy a new exploration ship and to retool another for sophisticated deep-water exploration off its coast. The Central Indian Basin, for example, is rich in nickel, copper, cobalt and potentially rare-earth minerals, which are highly lucrative and used widely in manufacturing electronics such as mobile phone batteries.
They are found in potato-shaped nodules on the deep-sea floor. "These nodules offer a good solution to meeting the nation's demand for metals," C. "The mining engineers have already tested some systems at lower depths and are in the process of up-scaling for deeper depths," Sharma told SciDev.Net.
Deep sea mining | Rare Earth Investing News. Deep-sea mining rights approved. Japan will acquire the exclusive exploration rights for a 3,000-sq. -km stretch of seabed some 600 km off its easternmost island, Minamitori, to retrieve rare metals including cobalt and nickel, the industry ministry announced Saturday.

MORPH: Marine robotic systems of self-organizing, logically linked physical nodes. Des chercheurs européens testent des robots sous-marins en Méditerranée. Depuis le 22 juillet et jusqu'au 27 juillet, 32 chercheurs de cinq pays (Portugal, Allemagne, Espagne, Italie, France) testent ensemble, pour la première fois et en pleine mer, dix robots sous-marins au Centre européen de technologies sous-marines (CESM) de l'Ifremer de la Seyne-sur-Mer.
Cette opération s'inscrit dans le cadre du projet européen MORPH. Ces robots adorent le travail d'équipe. Sans interconnexion physique, ils communiquent en permanence entre eux au travers de modems acoustiques, de réseaux virtuels et partagent des données capteurs. Ces robots sous-marins s'adaptent sans cesse aux obstacles et au terrain difficile, tout en analysant l'environnement sous-marin. Les applications potentielles sont nombreuses : protection des ports et des barrages, analyse et inspection d'infrastructures industrielles en mer, détection des mines, surveillance de l'environnement, exploration des ressources marines ...
