The End of Frade
The Brazilian National Petroleum Agency (ANP) is examining a scenario where a series of seabed leaks may occur in a 7km radius around the Frade oil field in the Campos Basin, due to sagging of the seabed in the area and fissures in the rocks surrounding the Frade oil reservoir. The Frade well is located 130km off the city of Macaé in Northeast Rio de Janeiro at a depth of 1,200 meters (3,996 ft). Although it is still unclear if Chevron, the main field operator is responsible for this due to having exceeded the pressure limits of the well, there is evidence that the super-major operator did exceed the well wall pressure limit. Transocean´s chief driller at the site…
RRC Robotics buys 2 ROVs from Schilling Robotics
The Brazilian ROV pilot training company RRC Robotica Submarina, has recently acquired two work class ROVs from majorn U.S. ROV manufacturer Schilling Robotics. RRC Robotics also offers specialized services such as; Consulting and Auditing ROV systems; 3D modeling of subsea operations; Subsea engineering; ROV operations and rental, sales and maintenance of ROVs and tools from its base in the City of Macaé, located northeast of the city of Rio de Janeiro. Macaé is also the main hub for all offshore O&G companies and service providers in Brazil. Schilling Robotics was founded in 1985. Schilling is headquartered in California U.S.A. and has regional offices in Texas U.S.A., Aberdeen, Scotland, and Singapore. Schilling Robotics also operates a service and support station in Brazil.
Marine Debris: Impacts Being Seen Even at the Smallest Levels.
If you have ever walked along the beach with family or friends, or maybe walking your dog you have encountered marine debris. It is a growing problem in oceans around the world. Defined as any man made object discarded, disposed of, or abandoned that enters the coastal or marine environment, marine debris may enter directly from a ship, or indirectly when washed out to sea via rivers, streams and storm drains. There are several types of marine debris including plastic, glass, metal, Styrofoam, rubber, derelict fishing gear, and derelict vessels. The main sources are ocean-based or land- based. Ocean-based sources includes fishing vessels who lose gear as well as recreational boats…
Australia Experiencing Shortage of Workers in Oil and Gas Industry
Australia is experiencing a shortage of workers in the energy sector. Due to construction of LNG export projects there has been a demand for workers. Chevron is attempting to hold information sessions in an effort to recruit workers. The high demand for engineers include subsea, civil, structural, pipeline design and construction as well as marine engineers. Bechtel is one of the leading companies in the area having built more than one third of the LNG projects in Australia. In Queensland, where they are responsible for construction on Curtis Island, 6,000 workers had to be moved back and forthacross the harbor for work. The company has attempted to modularize the job process by farming out some parts of the projects to shipyards in South East Asia.
Dynamic Positioning Marks 50 Year Anniversary
This year marks the fiftieth anniversary of dynamic positioning. Wikipedia defines DP as “a computer controlled system to automatically maintain a vessel's position and heading by using its own propellers and thrusters. Position reference sensors, combined with wind sensors, motion sensors and gyro compasses, provide information to the computer pertaining to the vessel's position and the magnitude and direction of environmental forces affecting its position". There is a segment of the Marine Technology Society that is dedicated to furthering the knowledge and understanding of this technology. The first DP system was built in the early sixties. During this time the first system was built by the CUSS group, a consortium of Continental, Union, Shell and Superior oil companies.
First Pre-salt Spill Highlights Deepwater Challenges
The accident that occurred on Tuesday, January 31 on the Dynamic Producer FPSO owned by Brazilian company Petroserv at the Carioca Nordeste field in the Santos Basin is a good example of the hard challenges found when drilling and producing in deepwater wells. During an extended well test a production column broke causing the spilling of approximately 160 barrels of oil (equivalent to 25 thousand liters). Although this can be considered a small spill, as compared to the 2,400 barrels spilled by Chevron at the Frade field in the Campos Basin in November 2011, it still a serious problem that needs to be addressed, the media didn´t pick…
Global Underwater Observatories: The New Frontier
The OOI of Ocean Observatory Initiative is a project funded by the National Science Foundation, and “is planned as a networked infrastructure of science-driven sensor systems to measure the physical, chemical, geological and biological variables in the ocean and seafloor”. It is a fully integrated network used for collecting data on a regional, coastal and global scale. The OOI is making real time ocean-observing data available to oceanographers, scientists and researchers, educators and the public. The first OOI data streams will be from coastal gliders and are expected to be available in 2012. All core infrastructure and instruments will be online by late 2014.
Changing The Game in Underwater Exploration
The Laboratory for Autonomous Marine Sensing Systems or LAMSS at MIT is working on some of the most cutting edge technology in the industry. It is a collaboration between Scripps, the University of California in San Diego and MIT. Their research focuses on “the development of distributed ocean sensing concepts based on fully integrated Sensing, Modeling and Control, taking advantage of the environment and situational adaptation and collaboration with clusters of sensing nodes, without the direct need for operator control”. Sounds like a mouth full, but the technology they have been working on and continue to develop is astounding. Developing technology like SWAMSI or Shallow Water Autonomous Mine Search Initiative…
Laje Viva Institute - Divers take a stand
The Laje Viva Institute was born from the indignation of a group of divers towards illegal fishing that, unfortunately, is a reality in the Laje de Santos Marine State Park. Divers spotted fishing vessels at the park and became indignant and irate with this practice, leading them to take action. From this point on, a few divers decided to meet and start to take action having a clear objective: "Protect Laje de Santos from fishing and hunting". On July 1st, 1993, these divers founded the Laje Viva Institute, a non-profit organization with the objective of implementing actions to guarantee the preservation and protection of the Laje de Santos Marine State Park (PEMLS).
