Survey: UK Subsea Industry Shows Signs of Optimism

Subsea industry supply chain companies in the UK are looking a bit more optimistic, with an improved outlook, less redundancies, and more work in offshore wind expected in the near future, a survey by industry body Subsea UK has shown.Subsea UK said Wednesday it had surveyed its 300 members in early July and then again in late November 2020 to provide evidence-based insight into how the supply chain was faring in the midst of the public health and economic turmoil of last year."In July, 73% of respondents did not anticipate making redundancies in the near future. This figure has increased to 80%

A unique double rotor floating wind turbine concept has earned a statement of feasibility from classification and certification body DNV GL.This statement, based on DNV GL’s technology qualification services, confirms that the nezzy² floater is designed to state-of-the-art safety, quality and performance standards, and allows its developer, aerodyn engineering, to secure investments and enter the next level of prototype development.The innovative floater is designed as self-aligning concrete structure attached by single point mooring system to the sea ground. The two turbines are mounted on

Partners Team Up to Develop Utility Class ASV

CSA Ocean Sciences Inc. (CSA) and SeaRobotics Corp. (SRC), both based in Stuart, Fla., are working together to jointly develop the next generation utility class autonomous surface vessel (ASV).Based on the fully integrated SR-Surveyor M1.8 ASV, introduced by SRC in 2019, the new utility class ASV will deploy the same fully integrated control, survey, and autonomy systems, providing the market with a fully compatible line of ASVs that are capable of addressing a wide range of tasks – from 1.8 m inshore/nearshore vessels to over 12 m ocean going vessels.The SR-Utility 3.0 and SR-Surveyor M1.

Unique Subsea Robots to Serve Norwegian Oil Industry from 2022

Norwegian subsea drone specialist Stinger Technology has entered into a collaboration agreement with the U.S. ocean robotics firm Houston Mechatronics.Houston Mechatronics is currently developing what has been described as one of the subsea industry's most interesting robots - the Aquanaut - and Stinger wants to bring it to Norway to serve the offshore oil and gas market.The Aquanaut is a subsea robotic solution that can serve both as a remotely operated vehicle (ROV) and as an autonomous underwater vehicle (AUV). Based on the requirements, the subsea robot transforms from AUV mode into an ROV.

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

Xerox and DARPA Partner to Develop IoT Ocean Sensors

.Initially announced by DARPA in 2017, the Ocean of Things project is deploying small, low-cost drifters in the Southern California Bight and Gulf of Mexico to collect data on the environment and human impact. This includes sea surface temperature, sea state, surface activities and even information on marine life moving through the area.“Oceans cover more than 70% of the earth’s surface, but we know very little about them,” said Ersin Uzun, vice president and general manager of the Internet of Things team at Xerox. “The drifters gather data that we could never track before, enabling

with BAS.”The new £200 million ($262 million) vessel will sail across the Mersey to the Liverpool cruise terminal at high tide for crew familiarization, before spending 14 days undergoing technical trials off the coast of North Wales. The shipyard engineers and British Antarctic Survey (BAS) mariners will put the ship through its paces, performing operational checks on the propulsion, steering, engineering and navigation systems.When technical tests are complete, the BAS ship crew will take over and spend 50 days intensive training at Holyhead Port before embarking on operational and scientific

New Lidar Tech Approved for Use by SGRE for Wind Turbine Testing

Siemens Gamesa recently tested a new technology together with ZX Lidars, and based on the results both on the medium range and long range measurements, Siemens Gamesa Renewable Energy (SGRE) approves the use of the nacelle-based Continuous Wave scanning Lidar ‘ZX TM’ from Lidar OEM ZX Lidars for Power Performance Testing.In addition, operational ‘rotor equivalent’ power curves can also be measured with ZX TM’s 50 points around the full rotor swept area, particularly important for turbines with larger rotor diameters offshore and on onshore sites with complex veer or shear

MacArtney LARS for Fifth Asia Pacific Research Vessel

MacArtney completed its order of a launch and recovery (LARS) system for Taiwan National University, the fifth Ocean Research Vessel (ORV) in the Asia Pacific region to date. MacArtney Asia Pacific provided the full launch and recovery system solution for the new vessel R/V New Ocean Researcher 1 (ORV 1), including slip rings, cables and docking heads. The 1,000 GT RV was completed on July 21, 2020.Behind ORV 1 is the CSBC Corporation, which built the ship for end-user Taiwan National University. CSBC, owning two shipyards, is the largest shipbuilding company in Taiwan. Now that ORV 1 has passed
