Fiber-Optic Connector Technology for O&G Ops

Fiber-optics (FO) technology is finding new uses in subsea applications. Fiber allows longer transmission distances and higher data rates than copper — a fortuitous development, as offshore drilling moves to deeper depths. Petroleum exploration and production are also becoming smarter, as operators pursue real-time information and analysis of both the individual well and the entire production chain from well to topside or land-based platform. Compared to copper, the high bandwidth of fiber allows richer data streams and much longer step-out distances (i.e., distance between subsea installation

, how they can support fish which are important for people, and how they store and process carbon, so that helps us understand the role of climate,” Warner said. “Ultimately, this multi-tool approach to this kind of research is critically important and has been shown to be really effective in oceans, but hasn’t been used to as much degree in the Great Lakes or other fresh water systems.”   The research team is now in the early stages of data analysis which will ultimately lead to a number of papers in 2017.   As for future AUV deployments in the Great Lakes, &ldquo

“During this summer we had the drilling operation based on our 3D and 4D images. But CAGE undertook several expeditions this year that also focused on retrieving data regarding the development of marine ecosystems in the dark ocean floor areas of the Arctic.” – Prof. Jürgen Mienert, CAGE Director (Photo: CAGE)

Methane: The Arctic's Buried Treasure

In pursuit for the Arctic’s buried treasure: methane   Trapped beneath permafrost and ocean sediments, the release of the world’s largest natural gas resource, methane, has become a hot topic for international research. As rising temperatures continue to warm the Arctic region, the vast frozen fields of gas, known as gas hydrates, grow unstable beneath the retreating ice. The Centre for Arctic Gas Hydrate, Environment, and Climate (CAGE) strives to address one of the greatest scientific uncertainties: how much greenhouse gas threatens to escape the sub-seabed sediments and what will

Seatools Debuts Subsea Compensator Range

Dutch subsea technology company Seatools has introduced its new subsea hydraulic compensator range: the Advanced series.   This new subsea compensator range, based on the preceding Hyco range, delivers improvements in robustness, durability and standardization, according to the manufacturer.   Seatools, a specialist in subsea hydraulic systems, said it performed an extensive development trajectory that led to the Advanced series. The new range, meant for heavy-duty subsea hydraulic systems – such as subsea vehicles (e.g. ROVs and trenchers) and dredging systems (suction tube SHPU

Airmar Acquires Former Materials Systems Inc.

 Airmar Technology Corporation has acquired the assets of the former Materials Systems Inc. (MSI) group located in Littleton, MA from Channel Technologies Group (CTG). MSI was founded in 1991, sold to CTG in October 2014, and post-acquisition, will be incorporated as MSI Transducers Corp.  AIRMAR’s President and CEO, Matthew Boucher, stated, “The integration of our piezoceramic transducers and sensor technology coupled with MSI’s piezocomposite transducer offerings enables us to diversify our product line and significantly broaden our offerings to the commercial and

Video: US Navy Tests Autonomous Swarmboats

The U.S. Navy is examining new possibilities for autonomy in future naval missions, putting autonomous unmanned vessels to the test in a recent demonstration in the lower Chesapeake Bay.   Officials from the Office of Naval Research (ONR), together with partners from industry, academia and other government organizations, leveraged a combination of high-tech software, radar and other sensors to get a “swarm” of rigid hull inflatable boats (RHIBs) and other small vessels – “swarmboats” – to collectively perform autonomous patrol missions with only remote human

CARIS Onboard 1.1 Launched

Marine mapping software developer Teledyne CARIS has released CARIS Onboard 1.1, which enables users to process data in near real-time resulting in minimized data conversion and processing times. Designed with autonomous operations in mind, CARIS Onboard will save time as less interaction is needed for automated survey activities.   This release introduces several new processes including the incorporation of the SIPS Backscatter engine. Backscatter mosaics can now be generated alongside surfaces in near real-time. This version also presents the ability to compute GPS tide, and apply observed
