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. A number of vehicles could even cover a cluster of fields, potentially with different owners who can dial up, on demand, a vehicle when

The Ocean's Microplastics Mess: Technology & Technique to Identify & Clean Up

The science and technology surrounding discovery, mitigation and clean-up of microplastics in the world’s environment makes this year’s “MTR100.” Here we offer insights on the organizations, people and technologies taking the lead.As marine journalists, scientists, technologists, activists and enthusiasts, we are aware of the large-scale impact that consumer macro-plastic products have on aquatic ecosystems. Ranging from plastic bags and straws to bottles and fishing nets, these materials pollute harbors, rivers, lakes and oceans, all while threatening the prosperity of wildlife

Subsea Mining: The Race is On, But Effects are Unclear

Mining the ocean floor for submerged minerals is a little-known, experimental industry. But soon it will take place on the deep seabed, which belongs to everyone, according to international law.Seabed mining for valuable materials like copper, zinc and lithium already takes place within countries’ marine territories. As soon as 2025, larger projects could start in international waters – areas more than 200 nautical miles from shore, beyond national jurisdictions.We study ocean policy, marine resource management, international ocean governance and environmental regimes, and are researching political

WHOI: Ocean “Pumped” to Capture More Atmospheric Carbon

While scientists have long known the essential role that the ocean plays in capturing atmospheric carbon, a new study from Woods Hole Oceanographic Institution (WHOI) shows the efficiency of this natural pump has been underestimated.The ocean’s “biological pump” is a critical part of the global carbon cycle and relies on phytoplankton, single-cell organisms that use photosynthesis to turn light into energy—consuming carbon dioxide and releasing oxygen in the process. When phytoplankton die or are eaten by zooplankton, carbon-rich fragments sink into the ocean, then consumed by

ABS Calls for New Tech in Marine Fuels

ABS Chairman, President and CEO, Christopher J. Wiernicki, mapped out the future of marine fuels, indicating that the 2050 targets will require technology beyond today’s state-of-the-art.“Technology advances of the next decade may entirely change our view of the future, but based on what we see today we can identify three developmental pathways for future fuels distinguished by the onboard technologies they require. These are: the LNG or light gas pathway, the bio/synthetic pathway and the alcohol and heavy gas pathway,” he said.“Within each of these pathways are many variables
