radius of 300m), but also travel distances between subsea fields, untethered, like an AUV, and both either from a seabed garage or a surface deployed system on a mission basis but also able to recharge subsea, Stefano Meggio, Subsea Robotics Technical Manager at Saipem told the energy: connected (aka Subsea Valley) conference in Oslo earlier this year. Rated to 3,000m, it could operate for 8-10 hours without a tether, and out to 10km, when it’s returning to the same base, or 20km, if it’s transiting to another base.Saipem is also developing a range of HyTool skids, suitable for all its vehicles

to enter the underwater domain is growing fast. The concepts vary, from underwater autonomous motherships able to carry an array of payloads over long distances to swarms of drop deployed ocean bottom nodes that can find their way to pre-programmed locations.At energy:connected, as the Oslo-based Subsea Valley cluster and annual conference is now called, some of these concepts were outlined, including those from two Norwegian technology firms and Germany’s Thyssenkrupp, a firm more used to designing naval submarine systems. uSEA unveils uLARSOne, Norwegian technology start-up uSEA, is proposing

the industry. There is now a field proven system that considerably reduces the time, personnel, space and cost compared to other existing solutions.”Optime Subsea first announced SCILS as a system to help optimize the future of well access operations during the Norwegian oil and gas conference, Subsea Valley, in 2017. At the same conference the following year, SCILS was revealed as a solution to the industry’s demand in solving today’s and future need for safer, simpler and more cost efficient operations. In 2019 the SCILS will the be in operation.Carlsen said, “For us, innovation

at excursion ranges of up to 12km and can operate much further in AUV mode, without the fiber cable.For autonomous operations, Sabertooth is fitted with sensor reactive control and enhanced navigation capabilities, says Peter Erkers, sales director, underwater systems, during the Subsea Valley conference in Oslo in March. These capabilities, including autonomous docking, got Sabertooth on Italian oil firm Eni’s Clean Sea project, a subsea monitoring system covering oil spill detection, pre-planned surveys along flowlines and pipelines, and inspection of subsea production systems

while these deployments meant the vehicles were autonomous in that they no longer needed a support vessel, they were still tethered and operated by staff onshore.The next step will be vehicles that can operate without a tether, such as Oceaneering’s new Freedom concept, which it unveiled at the Subsea Valley Conference in Oslo. It’s a resident ROV concept, based on a hybrid vehicle, that would live in a subsea docking station and be able to fly out on missions in either tethered (remote operated) or untethered (autonomous) mode. It would have onboard batteries that would be recharged at its
Optime Presents New Tree Control and Intervention System
At Subsea Valley 2017, Jan-Fredrik Carlsen, CEO of the Notodden based Norwegian company Optime Subsea, promised to revolutionize the intervention and controls segment of the subsea oil and gas industry through a new and disruptive technology. A year later at Subsea Valley 2018, Optime’s Subsea Controls and Intervention Light System (SCILS) was presented. "Our intent is not to be disruptive for the sake of being disruptive, but support the industry’s progress in providing cost reducing tecnology," Carlsen said. "I believe our SCILS demonstrates this. We identified an

The 19,000-psi hyperbaric pressure vessel will be manufactured by Optime Subsea in Notodden, Norway, located in the Norwegian subsea oil and gas cluster known as “Subsea Valley”. The hyperbaric testing chamber will have a diameter of 700 mm and a height of 1,400 mm. It will be delivered and installed at Nautilus’ newly upgraded facility in Q3 of 2017.
