Subsea Vehicles: To Be (resident), or Not to Be?


And we want to get rid of complex offshore lifting operations.” Another challenge is that if a resident drone can’t do one out of 10 tasks and a crewed vessel still has to come out without knowing when, it kills the business case, Steffan Lindsø, Subsea Robotics Product Manager at Oceaneering, says. However, it also has the Liberty E-ROV, a standalone system comprising an electric ROV with deployment cage, batteries and surface communications buoy, so it can be dropped off and left in field for weeks or months at a time without vessel support, offering temporary residency. This will come with a “smart dock”, which includes power and communications, says Jaques, eliminating the need to bring the AUV back on deck for charging and data download and reducing HSE risk. In addition, a separate Blue Logic inductive underwater power and GB capacity communications connector would provide a charging interface as part of the uLars towed dock. We’re just providing the launch craft and the means to communicate and control.” The XLUUV would be a hybrid power system, probably with a diesel generator to support recharging at sea, but with fuel cells in the mix in future, says Wilson.
