be greatly enhanced if you included some pictures of the “soft systems”. Such an article would be a real hoot.Keep up the good work,CharlieFrom Kevin Hardy:Thanks for the comments, Charlie. Yes, I focused more on deep water than shallow, and skipped over the use of compressed gas systems for buoyancy. Ultimately, Boyle’s Law (P1V1 = P2V2) determines the useful depth of a compressed gas system for buoyancy. That said, the shelf break of the continental shelf is nominally 100-200m, where pressures are just 10-20 bar. The compressed systems developed for that

the specific application. In addition, the Underwater Node systems provide the necessary infrastructure in terms of electrical power and data connections to continuously operate complex sensor systems having high power consumption on the seafloor and are eminently suitable for the CONTROS dissolved gas systems. Often deployed in shallow water, (< 300 m) the underwater node can be installed with a cable connection to shore up to 30 km offshore (3 nodes connected in series, each 10 km distance to shore) for year-round operation. Thus, providing the opportunity for a continuous observation of

We are just touching the surface.”The ConceptAt the moment, subsea oil and gas systems are electro-hydraulic. Each power consumer is fed with power and communications via separate umbilicals from a topside variable speed drive (VSD). Such a system has limited flexibility, should an operator want to add in a new well or a subsea pump.The subsea power grid concept, however, would

have collected and go back and fill them in, during a mission. An intelligent system like this was used to track plankton in the water column, having had to find the plankton in the first place then follow it. These capabilities will be crucial when systems are working with and around subsea oil and gas systems, which is expected to be one of the main areas where autonomous systems are required, along with ocean science, says Sørensen. For whatever the purpose, be it oil and gas exploration, renewables or aquaculture development, shipping or ocean science, the range and capability of subsea

; “The WIN WIN project has shown great potential for the oil and gas industry to lower costs and increase efficiency, while also reducing its environmental footprint," says project sponsor Johan Sandberg. "Proving that large-scale renewable units can be integrated well into oil and gas systems will also expand the industry's toolbox of technology solutions. It is a win for society with regards to emissions, and for the oil companies who can lower their costs on both equipment and operations.” “We are encouraged by the success of the first phase and look forward
