  • QINSy Bundle
    meters below the sea surface To mitigate sagging of any portion of the lengthy bundle it is necessary to make the bundle buoyant over its entire length Planning For such a long and expensive item a towing route is pre planned To ensure success close monitoring of the horizontal positioning bundle shape and bundle depth during the tow out operation is a key factor Position course and speed of all attending vessels are also of paramount importance of maintaining the shape of the bundle and keeping it on the planned route Positioning Bundle tracking is accomplished using multiple acoustic beacons attached at intervals along the entire length of the bundle Using USBL techniques the position and depth of each beacon is calculated in QINSy Shaping algorithms model the bundle between these known beacon positions so that the position and depth of the entire bundle is calculated in QINSy Position course and speed of attending vessels is transmitted to QINSy through telemetry Monitoring Visualization of the horizontal position of the bundle and attending vessels is provided by the Navigation Display against a background of electronic charts satellite imagery and or DXF drawings A Profile Display shows a side view of the

  • QINSy Pipelaying
    vessel tugs and pipe throughout the lay are of paramount importance Route As an integrated navigation system software package QINSy includes several features specially designed for pipe and cable lay that make it easy to ensure the pipe or cable is laid along the prescribed route The pipe route can be imported into QINSy or the line planning utility in QINSy is ideal for creating the path of the future pipe line During laying operations this route is shown on the navigation display and used by QINSy to calculate the barge track which is different than the pipe route itself and dependent on the offset from the vessel s reference point to the pipe s touch down point QINSy uses a layback method that takes the stinger length stinger radius water depth launching angle and other parameters into account in computing the touch down point During laying operations QINSy provides a dedicated administration tool to log events like field joints and other relevant occurrences Anchors tugs For vessels that move by pulling themselves forward on anchors QINSy includes various anchor handling functions including bi directional exchange via radio telemetry of vessel and tug position and transmission of target pickup and

  • QINSy Pipe Inspection
    Inspection surveys normally require a bathymetric survey of the seabed along the pipe or power cable route The multibeam system and associated sensors can be mounted on the vessel or on a ROV flying a few meters above the seabed USBL calibration When using ROV s positioned with USBL it is extremely important to perform a USBL calibration QINSy includes such a tool employing the standard calibration routines such as the four quadrant method the spin check and the Z check It also supports calibration routines for backward looking USBL systems Visualization QINSy has no limitation on the number of ROVs that can be positioned and displayed so QINSy can be used for complex ROV jobs as well QINSy provides several real time 2D and 3D displays to visualize the inspection as it proceeds If multibeam is used the sounding grid is built in real time during the multibeam survey giving operators an initial impression of the pipe condition During the inspection survey the QINSy operator can define an output of textual information used as an overlay on the video system Output If some sensor data is to be logged in 3rd party software QINSy can be configured to output

  • QINSy Side Scan Sonar
    navigation charts and or Geotiff images The Profile Display provides a side view of the fish relative to the towing vessel sea surface and seabed DTM This view is useful in determining appropriate winch reel in and reel out times A real time waterfall type display is used to present the imagery data itself Interesting features can immediately be captured using various targeting tools and stored as targets for future reference Target locations are shown in the Navigation Display as they are identified in the waterfall display Real time mosaicking of the imagery is done through normalization and slant range corrections If available the imagery can be geo referenced directly to a DTM The mosaic is shown in one layer of the sounding grid as viewed in the Navigation Display Processing For processing of the SSS data a dedicated SSS mosaic grid can be enabled in the Processing Manager This high resolution grid can be combined with other hydrographic data if available The Processing Manager includes a SSS viewer that is used for feature detection With the look and feel of the real time waterfall display this viewer provides the same functionality as the SSS display available during online recording
