    Fugro uses ConCat on near shore site survey

    News // December 19, 2003
    Fugro Survey A/S, an Oslo-based member of the Fugro Group, has announced that it recently used a ConCat survey catamaran to conduct a near shore multibeam surveyat Larvik, Norway.

    The harbour in Mørjefjorden south of Larvik has a customised loading berth for export of aggregates excavated in the region. Water depths at the berth are typically 10m or less, and an area of approximately 250 x 50m must be deepened to facilitate accessfor larger barges.

    Fugro Survey was contracted to provide detailed bathymetric chartsof the survey site, and saw ConCat as an excellent platform due to its highportability, and the quality of data from the integrated Kongsberg surveysuite.

    Stein Åsheim, survey manager for Fugro Survey A/S, said: "Smallmultibeam projects such as this can be very expensive in proportion to theactual survey time, due to lengthy mobilisation period when using charteredlaunches. All the survey equipment must be gathered, delivered to thelaunch, installed, integrated and finally calibrated. In this project, thecomplete exercise was completed in one day, acquiring high resolution EM3000D multibeam echo sounder data. Vessel motion, position and heading weremeasured via the Seapath 200 system, and all navigation signals wereprovided by Fugro Starfix."
