restricted human intervention, map at least 50 percent of the area – 250 km2, an area that is nearly three times the area of Paris – at five meters resolution and at depths down to 4,000 meters – a cold, dark and high-pressure environment that is more than twice as deep as the Grand Canyon – identifying and imaging at least 10 archeological, biological or geological features at any depth, all within 24 hours.At the end of the competition, a $4 million grand prize and $1 million second place prize will be awarded to the teams that receive the top scores for demonstrating the
Canyon Offshore Wins Wind Farm Trenching Work
Siem Offshore Contractors. Canyon said it will use jetting and cutting methodology with its Jet Trencher, T1200 and its hard ground trencher, i-Trencher. Both systems, together with two work class remotely operated vehicles (ROVs), will be deployed from a single support vessel, the chartered Grand Canyon I, with operations commencing Q4 2018. Management of the operations will be provided from Canyon Offshore Limited’s Aberdeen base.

, aiming to map at least 20 percent of the 500 km2 competition area at five meters resolution, identifying and imaging at least five archeological, biological or geological features at any depth, all within 16 hours. In other words, the competition technologies will aim to reach depths deeper than the Grand Canyon and map an area that is nearly five times the area of Paris. The 21 teams advancing are: ARGGONAUTS (Karlsruhe, Germany) – Led by Gunnar Brink, the team is creating a swarm of 12 intelligent deep-sea robot drones using insight gained through two previous projects.

used methods for assessing the benefits and costs of environmental policies and the economic impacts of environmental disasters. His projects have ranged from analyzing the benefits of the U.S. Clean Water Act and examining the impacts of fisheries management to studying visibility improvements in the Grand Canyon and preventing residential water shortages in California cities. After the Exxon Valdez oil spill, he served as a principal investigator on economic damage assessments for the State of Alaska and more recently for the National Oceanic and Atmospheric Administration on the BP oil spill in the Gulf
MacArtney AHC Winches for Canyon Offshore ROV Vessels
Canyon Offshore Inc., the marine contracting unit of Helix Energy Solutions, has opted for a MERMAC electric winch solution to empower the safe and efficient handling of ROV systems on board the latest two additions to the Grand Canyon family of advanced offshore support vessels. MacArtney has supplied a total of four winch systems, all featuring active heave compensation (AHC) allowing Canyon to launch, operate and recover their ROVs under rough sea conditions. With a global track record spanning two decades and a fleet of several purpose-built offshore support and construction
New Tech for Deepsea Deposit Exploration
to space exploration. The technology that allows us to reach these hidden worlds is vital to our understanding of them. The deep-seafloor we will be exploring during our expedition is an extreme environment of intense-pressure and eternal darkness hiding a rugged landscape akin to a combination of the grand-canyon and monument valley 3.5 kilometers beneath the waves.” “Whilst at sea we will be using new technology to navigate underwater instruments between extinct volcanoes, twenty meter high cliffs and towering chimney structures built by long-dead hydrothermal vents. The British
Canyon Offshore Mobilizes New ROVs
Canyon Offshore, subsea remote operated vehicle (ROV) operator, has mobilized two new UHD-III ROVs to their Grand Canyon II vessel. These new ROVs will enhance Canyon’s reputation for having the most robust and flexible systems for subsea field work. The Grand Canyon II is designed to perform a broad range of subsea operations, with DP3-class station keeping for work in severe weather conditions. It features a 250T heave compensated crane, facilities to launch port and starboard side ROVs simultaneously. The vessel’s first project was for survey and trenching work in the UK.
