    The POSIDONIA-SCAN project has been selected by ADEME in the framework of the “Initiative PME Biodiversite” European program

    SOACSY is pleased to announce that the POSIDONIA-SCAN project has been selected by ADEME (French environment and energy management agency) in the framework of the “Initiative PME Biodiversite” European program.

    Posidonia (Posidonia oceanica) is a plant covering most of the Mediterranean seafloor, protected species since 1988 because it provides a large part of the vital oxygen to the sea flora and fauna.

    The main objective of the POSIDONIA-SCAN project is to develop an acoustic system specially developed to provide additional information with a non-destructive process about the meadows and the meadow’s sub-seabed to the economic stakeholders of the coastline and/or for environment management in order to:

    - Support to the selection of new mooring areas, environment-friendly, and to dimension the ecological anchorages, with an effective cost and in a non-destructive way
    - Improve the knowledge of the matte (subsurface rhizomes and roots) for a better preservation
    - and monitor the Posidonia evolution.

    A great summer in the North Sea in search of UXOs prior to a major windfarm construction

    VATTENFALL selected the Soacsy multibeam subbottom profiler SEACHIRP3D to carry out an UXO survey on the Horn Rev3 Wind Farm siteFUGRO EMU was the survey Main Contractor and SOACSY provided equipment, measurement assistance and data post-processing.   

     HORN REV3, the site of interest, is a shallow area (glacial, with sea deposits of sand) in the eastern part of the North Sea, about 10 miles off the western-most point of DenmarkBlåvands Huk. The water's depth is between 12 m and 20 m. Some of the area is an old minefield from World War II.

    The multipurpose vessel MV VICTOR HENSEN, 40 m long, was used. The SEACHIRP3D  measurements were conducted between 06th August and 05th October 2015.
    Thanks to the multi-beam system, it was possible to cover a minimum width of 24 m at each line. 265 line files were processed representing 492 line km.

    The data were processed on board to allow delivery to Fugro EMU within 36 hours for the high priority items and 48 hours for the others from acquisition.

    A cable route survey across the Grand Canal d’Alsace for the new Kembs power plant

    EDF (Electricité de France) awarded a contract to SOACSY for a SEACHIRP survey close to the KEMBS Hydroelectric power plant near Mulhouse (68).

    In the framework of a new Hydroelectric power plan building, it is necessary to bury a power cable between both sides of the “Grand Canal d’Alsace” channel. The burial depth should be at least 1.5 m in order to avoid any navigation risk.

    The objective of the survey was to provide a detailed understanding of the seabed levels, characteristics and shallow geology in order to find the best cable route corridor.

    The SEACHIRP measurements were conducted between the 20/07/2015 and the 23/07/2015. The equipment worked perfectly, the collected data quality was fit for purpose and no HSE incident occured. 19 line files were processed representing 12 line km.

    The sun was invited to the survey.

    SeaChirp survey for tidal turbines foundation in the famously energetic Alderney Race (Raz Blanchard)

    In the framework of the PILE & TIDE projectSOACSY and GEOCEAN completed a SEACHIRP survey in the Alderney race (Raz Blanchard).

    The PILE & TIDE project is conducted in partnership by GEOCEAN and UCBN (CAEN University). It aims to set up an efficient procedure and methodology for tidal turbines installation. The project is supported by ADEME (Agency for the Environment and Energy Management).

    The Alderney Race (the French call it Raz Blanchard) is a strait that runs between Alderney and Cap de la Hague, a cape at the northwestern tip of the Cotentin peninsula in Normandy. A strong current runs through the race. The current is intermittent, varying with the tide, and can run up to about twelve knots during equinoctial tides.

    The seabed is mainly rocky with local sands, cobbles, pebbles and gravels areas. The main objective of the survey was to detect and localize these coarse sediments areas.

    The SeaChirp measurements were conducted on the CELTIC WARRIOR  (15m catamaran) between the 25th and 27th April 2015. The equipment worked well, the collected data quality was fit for purpose and no HSE incident occured.

    Offshore Survey 15: the SEACHIRP3D, part of a powerful solution for UXO detection in a presentation by FUGRO EMU

    During the Offshore Survey 15 Conference in the National Oceanography Center (Southampton, UK), Anne Chabert, Chief Geophysicist of FUGRO EMU presented the conventional and new marine geophysical methods for UXO detection.

    According to Anne Chabert, a one sensor solution will not provide sufficient information for UXO detection. A multisensory solution on a towed platform could provide a better compromise between costs/schedules and reducing the UXO risk.

    The new SOACSY’s SEACHIRP3D equipment, offering a large swath and good detection performance, was proposed as part of the solution…
