Rovco Launches Live 3D Subsea Streaming Technology

Subsea technology company Rovco (Bristol, UK) has launched 'SubSLAM Live’, a 3D streaming technology which allows users to video and live-stream 3D underwater point clouds to any device in the world. The stereo camera technology system sends images and 3D models of assets from the seabed to a computer browser in any location globally. This offers customers instantaneous access to information as an inspection or construction activity is taking place. The firm trialled the technology earlier in the year with an oil and gas Super Major, at a renewable wind farm, and more recently in 0.5m of visibility at an... (read more)

IMCA Revises Subsea Metrology Guidance

Subsea metrology procedures are expanding rapidly to provide ever-higher-accuracy solutions, so the publication by the International Marine Contractors Association (IMCA) of a revised version of ‘Guidance on Subsea Metrology’ (IMCA S 019 Rev. 1) is both highly relevant and timely.   The objective of subsea metrology is to determine accurately the relative horizontal and vertical distance between subsea assets, as well as their relative heading and attitude. Most commonly this is for pipeline connections and the document uses this work as an example throughout. The information determined by subsea metrology is then used by pipeline engineers to design a connecting... (read more)

Fusion 2 – An Evolution in Offshore Survey Operations

Complex set-up operations, multiple topside systems and interfaces, and arduous workflows; these are all now in the past. Sonardyne’s Fusion 2 survey software combines intuitive workflows with faster, more flexible INS, LBL and Sparse LBL aided INS operations - all from a single system. Since surveyors and subsea construction operatives took their first steps into the US Gulf of Mexico, followed by the harsh waters of the North Sea and beyond, the industry has been on a learning curve. From taut wire through to today’s digital signalling architectures, systems and methodologies, the industry has evolved. Developments in signalling technology have... (read more)

Secrets of Malta's Historic Water Systems

Miniature sonars, engineered by Tritech International, have been invaluable in helping to uncover the deep secrets of Malta's historic fresh water systems. Several reservoir sites in Malta and Gozo have been the focus of collaborative archaeological explorations by AURORA Trust, Marine Resources Development Foundation and California Polytechnic State University. The investigations aim to understand the complexities of underground cisterns and infrastructures and to research their evolution.   Tritech's ultra compact, CHIRP digital sonar was fitted to a small, remotely operated vehicle (ROV) and lowered into the cisterns. The ROV needed to travel between 30ft to 40ft from the access point... (read more)

Inspection and 3D Modelling Project at Galloper Offshore Windfarm Completed

Subsea technology specialist Rovco has completed an extensive ROV inspection contract. This circa £1 million contract has resulted in the completion of the baseline asset integrity survey at the newly constructed Galloper Offshore Wind Farm, a 353MW installed capacity wind farm which lies 30km off the coast of Suffolk, UK. The project, which was awarded by Innogy Renewables UK, began in September - with 24-hour ROV operations provided over a four-week period. Rovco deployed a Cougar XT ROV fitted with both 3D imaging sonar and their SubSLAM 3D technology to complete planned asset inspection activities. The project was performed from... (read more)

Acoustically Aided INS and Lidar

Fast 3D Subsea Mobile Mapping and Contactless Metrology
Aerial mobile mapping using Lidar and GNSS-aided inertial navigation has revolutionised the efficiency of land and shallow-water bathymetric surveying. Now, fast ultra‑high resolution subsea mobile mapping is approaching. Millimetre-resolution Lidar sensors have emerged in parallel with major advances in tightly integrated subsea inertial navigation. Wideband Doppler velocity navigation (DVL), Long BaseLine (LBL) observations, Simultaneous Localisation And Mapping (SLAM), automatic calibration and forwards-backwards post-processing, join with Acoustically Aided INS (AAINS) to provide robust dynamic sub‑millimetre relative accuracy and centimetric-level accuracy over wide areas. Successful deepwater ROV trials in the Monterey Canyon, California, USA, have demonstrated the extremely efficient dynamic future of... (read more)
