Pipeline Inspection with Fast(ER) Results

Finland’s Rocsole is hoping to provide operators with better, faster insight into their pipelines through a new compact inline sensor and a large dose of data analytics. Its inspection tool uses electrical tomography and digital signal processing to measure conductivity and permeability values within a pipeline. These are then analyzed to determine the content – fluid and solid – of pipelines or vessels, such as separators.The technology has had the backing of Shell, who are trialling the Deposition In-Line Inspection (DILI) in a 12 in. water pipeline in Brunei in October to detect

Japan to Release Fukushima's Contaminated Water Into the Sea

Nearly a decade after the Fukushima nuclear disaster, Japan's government has decided to release over one million tonnes of contaminated water into the sea, media reports said on Friday, with a formal announcement expected to be made later this month.The decision is expected to rankle neighboring countries like South Korea, which has already stepped up radiation tests of food from Japan, and further devastate the fishing industry in Fukushima that has battled against such a move for years.The disposal of contaminated water at the Fukushima Daiichi plant has been a longstanding problem for Japan as

Teledyne CARIS, a Teledyne Technologies company, said it was an integral part of the team involved in a recent uncrewed offshore survey mission in the Atlantic Ocean. Teledyne CARIS’ Mira AI and CARIS Onboard software were present on the vessel to enable autonomous survey and real-time processing operations.The mission’s uncrewed surface vehicle (USV) built by SEA-KIT mapped over 1,000 square kilometers of the ocean floor in 22 days, while being continuously monitored via satellite communications at its Remote Operations Center in Essex, U.K. A specialized team comprised of the GEBCO-Nippon

Applied Acoustic Launches New Subsea Positioning System

as diver monitoring, for deeper applications where ROV’s and AUV’s might be deployed, and for tracking short or long-range towed sensors such as magnetometers and side scan sonars."The combination of AAE’s Sigma 2 acoustic protocols and SBG Systems high precision Navsight Apogee Marine INS brings together two leading names in the field of marine technology, resulting in AAE’s most accurate and long-range positioning system to date, and in the process providing many time, cost and performance benefits to global survey operators," AAE said in a statement on Tuesday."

Optimizing Aquaculture with Sonar

Blue says in the movie Forest Gump there are an endless number of ways to prepare shrimp, which is probably why shrimp are one of the most consumed seafoods in the world.Traditional methods of wild-capture fishing cannot possibly satisfy the ever-increasing demand. Aquaculture, or the practice of farming marine life, has increased to meet this demand and now accounts for over half of all shrimp production. However, the shrimp aquaculture industry operates with little understanding of how much shrimp is in a pond. Farmers must take a “best guess” approach that ultimately results in incomplete

As ROV SuBastian makes its way up the slopes of the seamounts and canyons the team has been exploring this expedition, the changes in light, temperature, pressure, and other environmental factors are remarkable. From the dark and cold soft sediments of the plateau floor to exposed rocky escarpments, fields of mesophotic black corals, and eventually the well-lit realms of the upper slopes and reef crest - these changes lead to a whole gradient of habitats suitable in different ways for many diffe

New Corals Discovered at Great Barrier Reef

Australian scientists have viewed the deepest regions of the Great Barrier Reef Marine Park, discovered five undescribed species consisting of black corals and sponges and recorded Australia’s first observation of an extremely rare fish. They also took critical habitat samples that will lead to a greater understanding of the spatial relationships between seabed features and the animals found in the Coral Sea.The complex and scientifically challenging research was completed aboard Schmidt Ocean Institute’s research vessel Falkor, on its fourth expedition of the year, as part of the Institute&

Underwater Noise Study Completed for Washington State Ferries

A Massachusetts-based acoustical engineering consulting firm recently completed an underwater radiated noise study to quantify noise, potential impacts to orcas and other marine life, and methods of reducing noise for Washington State Ferries (WSF). Noise Control Engineering (NCE), a subsidiary of naval architecture and marine engineering firm Glosten, said its study included measurement of nine vessels representing all seven operating classes of WSF vessels. The firm specializes in noise and vibration design, measurement and control for marine, industrial and commercial applications.NCE utilized
