NEWS IN BRIEF Ifremer chooses iXblue technology for its new 6,000m AUV Ifremer, the French National Institute for Ocean Science, has contracted iXblue to equip its new 6,000m AUV CORAL project. CORAL stands for Constructive Offshore Robotics Alliance and aims at developing, in an industrial alliance led by Ifremer, a deep-sea seabed exploration down to 6,000m depth. The AUV will be equipped with a cutting-edge Synthetic Aperture Sonar (SAS), Sams-150, a Phins C7 Inertial Navigation System (INS), a sub-bottom profiler Echoes 5000 and will use iXblue’s Delph Software suite for SAS and navigation post-processing. Available as an AUV payload, Sams-150 expands the capabilities of conventional side-scan sonar for shallow to deep-sea applications. The Sams 150’s interferometric sonar will deliver co-registered full-swath backscatter and bathymetry data, increasing the achievable resolution and coverage rate from the ultra-deep water AUV surveys. The sonar will be used with iXblue SAS processing software, Delph SAS, which will ensure seamless integration to the workflow and interpretation features. The accurate coupling of SAS beam-forming and micro-navigation with the inertial navigation data from the Phins C7 onboard the AUV will result in optimal resolution and image quality in every environmental condition. Additionally, Delph-SAS will integrate the co-registered AUV’s multi-beam echosounder data, delivering full-swath bathymetry and sonar imaging. As the need for overlapping survey lines is reduced, the CORAL AUV coverage rate and autonomy will be maximised, thus saving time and mission costs. i. ixblue.com
Non-nuclear Density Analyser
A new generation of NON NUCLEAR density analysers based on Ultrasonic spectroscopy for a high accuracy density-measurement of the dredging slurry. The ceramic ultrasonic and thermal sensors are designed for abrasive slurries in the dredging and tunnelling industry. Technology Ultrasonic spectroscopy is the better and safer alternative for nuclear density meters. High energy pulses are included into the piezo element, an ultrasonic wave arises and propagates through the ceramic elements. The reflections from the interface between the element and the slurry are measured.

On sunday 19 July, deckcargo barge CC Atlantique safely arrived in Rotterdam, the Netherlands, carrying more than 8,000t of high voltage cables. The cables will form the connection from TenneT’s Hollandse Kust (zuid) Alpha Platform to the onshore grid. Blue Offshore is proud to be able to contribute to the Dutch energy transition, as it has been awarded the contract by Van Oord to supply a full cable transport spread for both the Hollandse Kust (zuid) 2020 Alpha and 2021 Beta cable transport campaigns. For this transport, Blue Offshore has mobilised the world’s first certified double basket carrousel barge, with each carrousel carrying approximately 4,000t of cable. The transport took place from Hellenic Cables in Greece. For this transport, the 122m long CC Atlantique was chartered by Van Oord. Besides the two large carrousels and dedicated control systems, Blue Offshore also provided all deck engineering, technical crew and complete mobilisation service. i. blueoffshore.com
