Composites X Steel Deepwater Pipes
The development of pipes that can withstand high pressure, heat and corrosion in deepwater locations such as offshore Brazil and the GoM and WA is continuous. For many years steel piping dominated the O&G industry but with pre-salt projects beyond 2,000 meters deep and corrosive enhanced oil recovery techniques widely being used in the industry, pipeline manufacturers have been looking for more flexible and robust materials. France's Technip, which is a world leader in pipe manufacture, uses layered steel with a stainless steel or plastic lining for main offshore pipes. However, British engineering company Magma Global and Dutch company Airborne are pioneering composite pipes made from a fusion of high-end fibers and plastics which are up to 90% lighter than steel pipes and do not corrode.

Pre-salt Production Start for P-58
Petrobras’s P-58 FPSO started operations at Parque das Baleias, off the state of Espírito Santo, on the north sector of the Campos Basin through well 7-BFR-7-ESS, another pre-salt producer, which is showing an excellent productivity. P-58 is part of the North project of Parque das Baleias, which encompasses production from Baleia Franca, Cachalote, Jubarte, Baleia Azul and Baleia Anã plays. P-58 is moored approximately 85 km off Espírito Santo, at a water depth of 1,400 meters. In the upcoming months, 15 production other wells, being 8 pre-salt and 7 post-salt, as well as 9 injection wells will be interconnected to it through 250 km of flexible pipelines and two subsea manifolds.
Compact Subsea Survey Tools - Meridian Ocean Services
As government agencies, research institutions, academia, and a range of industries look for new light-weight and low-cost solutions for subsea survey and inspection tasks, it becomes clear that new companies are entering the market with the goal of providing these specific services. At the same time the industry that manufactures the tools for these tasks, such as ROV’s, AUV’s and sensors and visualization software are also bringing in compact and affordable, yet powerful, products. Using the latest technology applied to inshore and offshore areas, these companies may soon be competing with established brands and in some case they offer services that few companies in the world can offer, creating their own niche.
Naturally-Occurring Radioactive Materials in the O&G industry
Nuvia is one of the leading provider of Naturally Occurring Radioactive Material (NORM) management services in the UK. According to the U.S. Geologists have recognized their presence since the early 1930s and use their presence as a method for finding petroleum systems. Much of the petroleum in the earth's crust was created at the site of ancients seas by the decay of sea life. As a result, petroleum deposits often occur in aquifers containing brine (salt water). Radionuclides, along with other minerals that are dissolved in the brine, precipitate (separate and settle) out forming various wastes at the surface, such as mineneral scales inside drilling and production pipe, sludges, contaminated equipment or components and produced waters.
Hadal Ecosystem Expedition Takes Off
An international team of researchers is using the unique deepwater Hybrid ROV Nereus, and other advanced technology to explore life in the depths of the Kermadec Trench, which runs northeast from the North Island of New Zealand. The 40-day expedition, which began on April 12th, kicks off an ambitious three-year collaborative effort funded by the National Science Foundation (NSF). The goal of the project, known as Hadal Ecosystem Studies (HADES), is to conduct the first-ever systematic study of life in ocean trenches, comparing it to the neighboring abyssal plain at depths between 3,000 and 6,000 meters. Due to the extreme pressures of these deep-sea environments and the technical challenges involved in reaching them…
Brazil Coastal Monitoring
Bounded by the Atlantic Ocean on the east, Brazil has a coast that is 7,491 km (4,655 mi) long. Offshore, numerous islands and archipelagos form part of Brazilian territory, such as Fernando de Noronha, Rocas Atoll, Abrolhos, Saint Peter and Paul Rocks, and Trindade and Martim Vaz Islands. Yet Brazil has no Coast Guard, the coast being patrolled by the Brazilian Navy, which does not have a mandate to make arrests, but which does keep in check illegal fishing. Costal policing would theoretically be done by the Federal Police. However, the reality is that they do not have anything near enough assets to patrol such a large coast. In terms of environmental monitoring…

Oil Rig Ballast Control System Accidents
Ballast control systems are a vital part of semi-submersible oil platforms. The ballast control system is made up of a network of pipes, valves, pumps, and tanks, which work as a liquid control system to keep the vessel at an even keel. Offshore drilling is an extremely risky undertaking, which is susceptible to accidents, which may cause human casualties and environmental disasters. One of the key systems necessary to keep oil rigs afloat, is the effective design of the user interface for the ballast control system, which significantly contributes to overall safety of a rig’s crew and the environment. The threat of disaster is the main reason to provide the operators with the most effective ballast control system possible. One such disaster occurred in 2001 aboard Petrobras’ P36 oil rig.

UN Bans Japan from Antarctic Whaling
The UN's International Court of Justice (ICJ) has ruled that the Japanese government must halt its whaling program in the Antarctic. It finally agreed with Australia, which had presented the case in May 2010. Australia’s case claimed that the Japanese whaling program was not for scientific research as claimed by Tokyo, arguing that the program was commercial whaling in disguise. A score of other countries have condemned Japan for the practice, yet it took 4 years for UN’s ICJ to pass its verdict. The court's decision is considered legally binding. Reading out the verdict, Presiding Judge Peter Tomka said the court had decided, by 12 votes to four, that Japan should withdraw all permits and licenses for whaling in the Antarctic and refrain from issuing any new ones.
Corals track strongest Indian Ocean Current
Researchers used corals as temperature archives. Natural variations in the warming and cooling cycles of the Agulhas current core region have been revealed from Madagascar corals. A new study, led by The University of Western Australia and with contribution by Professor Christian Dullo from GEOMAR Helmholtz Centre for Ocean Research Kiel, has been published in Nature Scientific Reports. The Agulhas Current, which flows down the east coast of Africa, is the strongest western boundary current in the Southern Hemisphere. Changes in its strength and the heat budget it transports are of interest, both on regional and global scales. The current is also the gateway for warm and salty Indian Ocean water that slowly goes up the Atlantic on its way to the far northern Gulf Stream.
25th Anniversary of the Exxon Valdez Oil Spill
On March 24, 1989 the oil tanker Exxon Valdez ran aground on Bligh Reef in Prince William Sound, Alaska, spilling an estimated 11 million gallons of crude oil across 1,300 miles of coastline. The tankers grounding and subsequent oil spill lead to one of the most thorough examinations of the effects of oil on the environment. While the vast majority of the spill area now appears to have recovered, pockets of crude oil remain in some locations, and there is evidence that not all resources affected by the spill have recovered to the previous state. No one anticipated any unusual problems as the Exxon Valdez left the Alyeska Pipeline Terminal at 9:12 p.m., Alaska Standard Time, on March 23,1989.
