Will 2020 be the year for Subsea Mining?

.pdf TechnicalWhen transitioning from the prospecting phase to the commercial exploitation phase, there are four main challenges to be faced:1. Designing and building a suitable mining support vessel or installation.2. Designing and building proper subsea mining tools – that is, the machines actually perform the mineral extraction on the seafloor.3. Designing and building the riser and lift system for transporting the mineral slurry to the surface.4. Once on the surface, dewatering and cargo handling.However, the most daunting technical challenge

called UX-1b to map and monitor the contours of confined sunken mines, and an EU-backed consortium is also about to launch (as are the Norwegians) a mining system comprising a nodule-crunching tracked vehicle, its launch-and-recovery unit and a specialty “drone”. In fact, the future of subsea mining looks set to always be a tracked vehicle with a supporting cast of ROV, AUV and now HROV escorts.The EVA subsea-mining support vessel, a hybrid or HROV, is part of a mining system that consists of a large, 20-tonne mining vehicle and a surface launch-and-recovery barge that might be easily replaced

environmental temperature, pressure, sound velocity and inclinometer sensors. Low power consumption (up to four years of battery life in listening mode) and intelligent ping management feature make Canopus suited for subsea operations such as seafloor Geodesy, subsea monitoring, construction or subsea mining.“We needed a highly accurate and reliable system able to provide precise measurements over many years,” said Jean-Yves Royer, in charge of the project at the IUEM. “The autonomy provided by the Canopus transponder, along with its ease-of-use and the availability of the iXblue

Exploring Deep-seafloor Mineral Deposits

A new project funded by the Natural Environmental Research Council (NERC), and led by Professor Bramley Murton at the National Oceanography Center (NOC), will aim to reduce the potential environmental impact of future subsea mining by making exploration for deep-seafloor mineral deposits much more effective.Many deep-seafloor mineral deposits, which can provide vital new metals for emerging technologies, including those that will reduce greenhouse gas emissions, were formed by hot springs on the seafloor. The big question facing geologists is whether these deposits – the vast majority of which

SMD Tests Subsea Mining Vehicle Prototype

A new robotic underwater mining vehicle prototype has completed first stage testing in a project set to uncover valuable European underwater mineral resources.   U.K.-based subsea engineering specialist Soil Machine Dynamics Ltd (SMD) is technical lead on the VAMOS (viable alternative mine operating system) project, a 42-month international research and development venture, which is part-funded by the European Union’s Horizon 2020 research and innovation program.   At a cost of approximately €12.6 million ($14.9 million), SMD and its partners in the VAMOS Consortium, have

subsea technology related research and deployment across the U.K.   Through its technology roadmaps, associated workshops and industry engagements, NSRI is marrying the industrial need with the technology providers and research capability across the U. K. This includes marine renewables and subsea mining as well as subsea oil and gas. It has also delivered an online matchmaker service which receives around 600 hits per month, and a series of high profile events that have achieved exposure among the end users of technology, innovators, sponsors and academia.   Chairman of NSRI, Peter Blake

The Price of Subsea Mining

Over millions of years, metal particles accrete onto sediment grains slowly forming lumps of commercially-valuable metallic ores in deep aphotic basins three miles underwater. As resources dwindle, mining companies are increasingly looking to the ocean to provide the metals and minerals we need. But environmental concerns hang heavy over the deep-sea mining industries. Before we venture into places untouched by humankind, the ABYSSLINE project sought to discover what animals wait in the path of destruction and, more importantly, what fate has in store for those communities when mining begins.   P
