Researchers Find Mysterious Seafloor Holes

. Image: © 2019 MBARISeafloor pockmarks have been found elsewhere around the world, and have been associated with releases of methane gas or other fluids from the seafloor. Such methane releases could potentially cause the seafloor to be unstable, which could pose risks for structures such as offshore oil platforms or wind turbines.  However MBARI researchers found no evidence of methane in the sediment or seawater in this region. In fact, sonar data showing layers of seafloor sediments suggest that these pockmarks have been inactive for the last 50,000 years.In contrast to the pockmarks, the micro-depr

New Floating Wind Center Launched

MEECE activity and, working with our university partners, we will be driving synergies across wind, wave and tidal to accelerate growth across these key components of offshore renewables.    Eight initial projects will kick-start the Center's activities. These include:•Powering Offshore Oil Platforms Using Floating Offshore Wind Turbines•Hybrid Bottom Fixed/Floating Offshore Wind Sites•Grid Connection for Scottish Offshore Wind / Off Grid opportunities including H2•Floating Substructures for Fabrication in Scotland•Mapping Scotland’s Floating Offshore Wind Supply

The “Disruption” in AUV Trends

the software and electronics of the smaller, proven, multi-role REMUS 100, the larger REMUS is sure to impress a U.S. Navy contemplating missions as mind-blowing as patrolling transatlantic cables; knocking out seabed listening posts or hardening vital national infrastructure like harbors and offshore oil platforms. Mission possibilities, especially recce, are as boundless as the imagination.Yet, despite the financial clout of Kongsberg Maritime and its worldwide researcher ties, the pioneering ISE, with its scalable units, sees itself as a credible rival even on contracts for large, deep-diving AUVs:

Project to Enable Autonomous Navigation in Denied Environments

Global Positioning System (GPS) data.Trials later this year will to incorporate water track velocity data, using Sonardyne instruments, to further aid the INS positioning. Guidance Marine will also deploy its recently launched SceneScan product, which maps surface features of structures, such as offshore oil platforms, processes the point cloud data and applies simultaneous localisation and mapping (SLAM) techniques to provide relative position data – further expanding autonomous navigation capability.  “By proving and demonstrating these technologies, we will enable autonomous vessels

Diving Deep for Conservation

;s thesis advisory panel. “The Rigs-to-Reefs program’s goal is to save industry money, while at the same time having them share the savings with environmental groups. It’s a win-win for the two factions, but an even bigger win for the organisms that have made these underwater offshore oil platforms their homes, as they will, hopefully maintain the deeper parts of these structures.”   The future looks bright for the ladies of Blue Latitudes, and they already have plans to expand their expertise to international waters. They have an expedition planned in March 2017 to Malaysia

TE Debuts Subsea CiA LVDT Position Transmitter Featuring CANopen Interface

. Macro Sensors SSBR-937 Series CANBus LVDT Position Transmitter can be used in a variety of subsea measurement systems, including elongation measurement as part of long-term finite element analysis of pipelines, derricks, moorings, choke valves and other critical high-stress members on offshore oil platforms that must be constantly monitored to ensure ongoing drilling platform stability.  The position sensor also can measure the extension of structural members of oil platforms to a fraction of a microstrain. To ensure oil platforms don’t shift, movement is measured to less than 2mm.  

Finite Element Analysis of Pipelines on Offshore Oil Platforms Offshore LVDT Linear Position Sensors

Macro Sensors Unveil Offshore LVDT Linear Position Sensors

, Macro Sensors Offshore LVDT Linear Position Sensors are quickly becoming the preferred technology in marine and offshore applications, especially for elongation measurement as part of long-term finite element analysis of pipelines, derricks, moorings and other critical high-stress members on offshore oil platforms that must be constantly monitored to ensure ongoing drilling platform stability. In addition to providing measurement from micro inches to two feet with excellent repeatability and precision, Macro Sensors Offshore LVDT Linear Position Sensors are built to operate for at least twenty years

Victaulic Debuts Delta-Y Assembly for Offshore

Victaulic  introduces the Style DLY Delta-Y assembly, a combination of preassembled Victaulic cast grooved fittings, rigid couplings and butterfly valves. The Delta-Y assembly is designed specifically for bulk cement/barite systems on offshore oil platforms and is also ideal for drilling mud and other associated systems. The Delta-Y assembly offers quick and simple installation, space and weight savings, efficient operation and reduced maintenance downtime. The Victaulic Delta-Y assembly speeds fitting and valve installation. Each preassembled unit is delivered complete with all fittings and

Petrobras Likely to Miss 2014 Output Goal

Brazil's state-run Petrobras will probably not meet its oil and gas production target for 2014 because of continued delays in the startup of new offshore oil platforms, a government source with direct knowledge of the situation told Reuters on Monday. Petrobras set a 2014 goal of increasing output by 7.5 percent, plus or minus one percentage point, hoping to break a string of missed targets caused by declining output from its largest existing fields and delays in new areas.
