MTR100: When it Comes to Drones, Big is Good. <1m is Better.
Over the last couple of decades, autonomous underwater vehicles (AUV) have become fully established work horses of ocean mapping and surveillance. That doesn’t mean there’s not room for some innovation. Elaine Maslin takes a look at some activity in the sub-1m collaborative drone market.New breeds of AUV are on their way. Some are bigger, but there’s also a host of companies developing small (<1m)…

Subsea Vehicles: To Be (resident), or Not to Be?
That’s the question? Or, more specifically, are there alternative ways of delivering robotics to where they’re needed without having to have seabed docking stations? Elaine Maslin takes a look. The idea for some kind of resident subsea vehicle has been around for some time. From BP’s considerations in 1986 for an integrated ROV launch system onboard the SWOPS oil production system to support subsea…

ROVs: Time for Renewal in the Work Class world?
There are tentative signs of the start of a renewal in the work class ROV fleet. But what form will it take?The work class ROV (WCROV) market has taken something of a battering over the past few years. The 2014 downturn and then a pandemic has meant the ROV services market and the fleet have suffered (see panels), alongside the rest of the offshore industry.Oversupply, thanks to a spate of investment in new vehicles through 2010-2014…

Subsea Tech: Taking 3D Printing to the Seabed
Underwater pipeline repair is an unavoidable and also fairly intensive activity within the offshore industry. There’s a lot of it on the seabed, some of it is old and/or subject to corrosive substances and even damage by anchor or trawler gear. Until now, its repair is largely through installing clamps over specific defects or cutting out and then welding in new sections, when there are multiple defects…

Subsea Mining: All Eyes on Marine Minerals Offshore Norway
Marine minerals are coming under sharp focus offshore Norway. Analysts suggest it could be a $20 billion annual revenue industry by 2050, which is why many are taking an interest and developing the technology to make it happen. Marine mineral mining has been something of a slow burner in the wider marine world. It has some clear challenges, not least location and depth of these potential resources…

Need a Survey? There’s a USV for That
While the adoption of unmanned/uncrewed surfaces vessels (USVs) was initially in defence, use of these low footprint systems has spread into other sectors, not least survey, and now the race is on for greater capability, endurance and autonomy. Elaine Maslin reports.After starting small, in inland waterways, use of USVs for survey operations has moved into coastal and now offshore waters. Given the extensive amount of seabed and rapid growth in offshore wind…

Subsea Tiebacks: A Troll with a Kinder Surprise
Equinor’s Troll Phase 3 project has been described as a real Kinder surprise. It’s Equinor’s most profitable project ever and comes with a minimum CO2 intensity for an offshore project. Elaine Maslin takes a look.Later this year, Norway’s Equinor is due to bring on stream its “most profitable project ever”. With a breakeven of less than $10/barrel, it’s indeed a low-cost project. It’s also got a low carbon footprint…

2020: A Year Like No Other with a Mixed Outlook for Subsea
On many levels, 2020 was a pretty horrific year, “a year like no other”, according to Mike Beveridge, managing director of energy investment firm Simmons Energy, a division of Piper Sandler. It’s easy to see why. A dip into a negative WTI contract prices, Brent troughing at $23/b – the indicators were all pretty grim. The scary thing is, it could have been worse. But there is light at the end of the tunnel.Speaking at the Society of Underwater Technology’s (SUT) annual subsea market outlook…

Fiber Optic Sensing and Mining an Ocean of Data
Fiber optic sensing is opening up vast new areas of research and data gathering potential, not least across our oceans, where existing cables could offer a new global sensing network. Elaine Maslin reports.Criss crossing between our nations, across channels and between continents are a multitude of cables – some 120 million km of them. Some are pretty old (the first international submarine cable was laid across the Channel, between the UK and France, in 1850).

Autonomy: Inside the Building of Ocean Infinity’s Armada Fleet
Back in 2017, Ocean Infinity made a novel move; deploying six autonomous underwater vehicles (AUVs), instead of just one, from a single vessel, vastly increasing the ground that could be covered in a single survey. Now the firm is taking the use of remote, robotic systems a significant step further.Back in 2017, Ocean Infinity made a novel move; deploying six autonomous underwater vehicles (AUVs), instead of just one…

Putting Power on the Seabed: Edging towards a Subsea Powerhouse
Ten years ago, a future where subsea fields and their power-hungry process equipment could be fully electrified, enabling long step-outs to tap remote reserves with lean new infrastructure architectures, lit the fuse for a spate of investment in subsea power distribution.The result, following at least two major joint industry projects (JIP) and tens of millions of dollars of investment, is that subsea power distribution is now a ready technology…

What's In Store for 2021? More Remote, More Data, More Autonomy
Late 2018, before net-zero targets had been agreed to by most western energy giants and nations, BP came out with a goal to reach 100% of subsea inspection by marine autonomous systems by 2025.It was a tangible goal then, and it’s one that might now be reached faster as remote and more “digitally” oriented operations take hold with greater opportunities for new nimble players in the market. It’s a goal being chased in the offshore wind sector too.Some of it is about emissions targets.

Unmanned Marine Systems, Squared
Unmanned platforms and underwater vehicles have been providing new ways for ocean scientists to study the ocean in more detail and over longer periods. What happens if one can deploy the other?The advantages of unmanned systems deploying others are multiple, not least in our expansive oceans. Deploying a glider (down to 1,000m) using a wave-propelled unmanned surface vessel (USV) means data can be…

Subsea Technology and the New Routes to Residency
Efforts to increase remote capability often go hand in hand with increasing ROV residency. But exactly what form residency takes is diverging. Elaine Maslin takes a look.Dial back the clock five years and there was a movement towards an idea dubbed subsea resident remotely operated vehicles (ROVs). The idea, in simple terms, is that you increase ROV availability and reduce cost and carbon emissions by having the vehicle permanently based subsea in underwater garages.
