Passive Monitoring Systems Deployed for Australian Projects
continuous monitoring of temporary suspended wells in the remote field. The systems were installed onto two 18 ¾” wellheads from a vessel of opportunity, and no in-well intervention was required.In another project, Sentinel Subsea successfully deployed two WellSentinel™ Coral-Frond Hybrid systems for a major client. These systems, designed to monitor two suspended wells, feature a Coral design enhanced with a Frond-type gathering structure. This enhancement allows for monitoring an area approximately five meters external to the wellhead.Components for both projects were manufactured locally
What's In Store for 2021? More Remote, More Data, More Autonomy
of the underlying technologies that enable remote operations and autonomy have become increasingly available over recent years, from terrestrial communications, including satellite and marine 4G networks, to underwater communications, including free-space optics, acoustics radio, and hybrid systems, says Ling.Emerging low earth orbit satellites will further expand what’s possible.But another enabler may also finally come to market: subsea electrification. Subsea electrification could enable increased use of subsea processing, from pumping through to compression, enabling longer subsea
Offshore wind: One-stop Power Conversion
owners, about as much as 2,000 cars per year. Its six engines can run as three, and its three battery packs are similar to the Fred Olsen wind-carrier jack-up vessel. “An electrical bus switch for their vessel cut the cost of operations and of fuel by 50 percent and allows its three different hybrid systems to work as one.”In Norway, of course, government does offer funds for conversions to greener power, and so owners are not paying the full cost. It’s a national drive, and “Shipowners say the ships should be easy to convert to new fuel,” said Parpala.China offeringWhile
Ocean Discovery XPRIZE Testing Altered
with middle and high school students, university teams of undergraduate and graduate students, nonprofits, startups and professional scientists and engineers. Representing 13 countries across five continents, the Ocean Discovery XPRIZE semifinalist teams’ innovative approaches involve unique, hybrid systems that mobilize gliders and drones, underwater robotic swarms, autonomous underwater vehicles, robotics, artificial intelligence and massive computing platforms. Once launched, these robots and vehicles use artificial intelligence to navigate and explore, gathering underwater data for retrieval

and erosion, as well as additional benefits and the tradeoffs when decision makers choose one type over another. “When making coastal protection decisions, it’s important to recognize that built infrastructure only provides benefits when storms are approaching, but natural and hybrid systems provide additional benefits, including opportunities for fishing and recreation, all the time,” said Ariana Sutton-Grier, Ph.D., the study's lead author, member of the research faculty at University of Maryland and NOAA’s National Ocean Service ecosystem science adviser. “Natural

Subsea Wireless Group Reports Successful Second Year
to demonstrate how wireless is already being used within the industry and this will be made available to all members. The Standards Working Group is focused on developing a recommended practice for radio frequency communications which will later be used as a template for acoustic, optical and hybrid systems. The focus of the Standards Working Group is to build on existing open standards with the objective to develop new standards that support full interoperability between hardwired and wireless systems subsea. www.subseawirelessgroup.co
A USV Franchise Grows Strong in Abu Dhabi
hybrid propulsion system gives the USV the ability to loiter for extended lengths of time, an intelligent system that allows the user, for example, to use only one jet at a time to hold station, effectively extending battery life and subsequently loiter time by eight to 10 hours. “A lot of the hybrid systems have been developed for recreational use to give you electric power out of the marina. But we are obviously looking for something that will provide hundreds of thousands of hours of reliable use,” said Keith Henderson, Director, 5G Marine Systems LLC, and the man that Murphy credits with
