Pipe Profiling Sonar Model 1512E

The resolution and update speed of the Model 1512E Pipe Profiling Sonar is second to none in the field of mechanically scanned sonars. The angular resolution of the system is 0.9° which gives 400 sectors per revolution. For each sector the data is oversampled and peak detected. The digitally generated graphics display uses 256 colours to represent the signal amplitude. At a minimum full-scale range of 125mm this gives a range resolution of 0.5mm and at 3m range the resolution is 5mm.

The acoustic beamwidth of 1.1° ensures that the finest detail from the pipe surface is recorded. A 3 axis accelerometer inside the scanner record the attitude of the sonar to a resolution of 0.1°. The sonar has been engineered for extended operations in hostile environments. The transducer and drive motor are totally enclosed in an oil-filled pressure balanced housing which is hermetically sealed from the stainless steel electronics pod. The system has many applications other than inside pipes where short range high precision measurements are required with a rapid screen update.

3D Profiling Sonar Model 2001

The 3D Profiling Sonar System provides a unique opportunity to capture short range 3D bathymetry data at high resolution. The acoustic transducer scans a horizontal swath and is then rotated by a small angle and another swath captured until a complete circular area underneath the sonar dome is covered.

FEATURES INCLUDE o

High resolution 3D data captured directly

o

Built in CTD, Pitch/Roll sensors used to calibrate data stored by sonar

The model 2001 is available in either a cable connected or self-contained logging version. The sonar may be fitted with optional Conductivity, Temperature, Pressure, Pitch and Roll sensors. With the full complement of sensors the logging unit can process the raw data to arrive at an ASCII “XYZ” file directly. The logging version has an internal Ethernet link which may be used to upload the stored data without opening the pressure housing.

o

"Windows '98, ME, 2000, NT, XP software with multiple views

o

Raw data logging to mass storage allows alternative post processing methods

o

Cursors for accurate on screen measurement

The underwater housing is typically mounted on a sub-sea framework or pole and deployed for several weeks or months. Internal scheduling software wakes the system from a low power sleep mode to capture data periodically. For tidal surveys a “wet-switch” may be specified so that the sonar only captures data when immersed.

o

Available as a logging system, cable connected, or split-head variants

o

No external rotating parts

o

Pressure balanced sonar dome

The system software provided has facilities for programming the scheduling as well as displaying the raw data or “XYZ” files from the sonar. The "Windows" interface significantly reduces the time taken to learn the system, minimising training requirements.

3D Profiling Sonar Model 2001 The resolution of the 3D Profiling Sonar sets a new performance benchmark for short range bathymetry sonar systems. The high frequency acoustic transducer scans a narrow “pencil” beam along a swath whilst an advanced multireturn processing algorithm extracts the range to the sea-bed from the raw data. In logging form the system then uses the data from the Conductivity, Temperature and Pressure transducers to calculate an accurate value for the Velocity of Sound in the water at the sonar head. The Pitch and Roll sensors provide attitude correction so that the 3D surface data is orientated correctly allowing features such as scour to be accurately quantified. In “split-head” format (see below) the sonar can be used for quantifying sludge levels in tanks or vessels containing hazardous substances for process control monitoring. The 3D sonar underwater unit is available in a “split-head” format allowing the electronics to be mounted at a distance from the sonar head. There are no semiconductors inside the sonar head unit, which allows it to capture data in the harshest of environments. For example, in areas of high radioactivity it will continue to function for much longer than a conventional sonar with on-board electronics. The split-head unit connects to the Electronics Processing Unit shown on the left via an umbilical cable. Both the Logging version and the Split-Head version have internal pressure balancing cylinders to compensate for the expansion/contraction of the oil in the sonar dome due to thermal and pressure effects.

Sand Ripple Imaging Sonar

The STABLE II platform being lowered into the flume to act as a target for the Sand Ripple Imaging Sonar

The image above was measured using the Sand Ripple Imaging Sonar and shows small sand ripples as well as the feet of the STABLE II instrument tripod. Dark areas of the image represent low signal levels, or shadows, whereas bright areas represent strong signals, or targets. The sides of the flume define the upper and lower boundaries of the image. The central hole results from the height of the sonar above the seabed and the vertical beam pattern of the sonar transducer. The Sand Ripple Imaging Sonar is mounted vertically on a pole suspended from above the flume which causes a shadow in the six o'clock position. The Sand Ripple Imaging Sonar has a narrow horizontal beam pattern and a wide vertical beam pattern. The transducer is rotated in the horizontal plane and data gathered for every 0.9째 of the revolution. The sonar operates as a slave to a host computer which controls the sonar via an RS232 serial data link. The acoustic receive signal is amplified and sent to the host computer as an analogue signal allowing free control over the digitisation of the data at the surface. Images Processed and Presented by

The platform has now been removed from the flume and the ripple period enlarged. The imprints of the platform feet are clearly visible.

Sand Ripple Imaging and Profiling Sonars The Sand Ripple Imaging (SRI) Sonar provides high resolution images in a transportable PC format for the minimum cost. Typically the sonar would be mounted near to the seabed and used to scan a circular area of the seabed up to 5m in range. The SRI Sonar operates at 2MHz with a 1° horizontal beamwidth and a 30° vertical beamwidth. Alternative transducers may be fitted to give different beam patterns and ranges depending on the specific application. In use the SRI Sonar requires a serial connection to a PC which controls the scanning process. The analogue output from the sonar provides freedom in the users choice of external signal processing. The transducer is fully enclosed in an oil filled rubber "boot" with no external rotating parts for complete environmental protection.

The Sand Ripple Profiling (SRP) Sonar effectively operates as an imaging sonar as it digitises the amplitude of the returned echoes over a programmed range. This approach allows the user to post-process the data to remove noise and mid-water targets caused by sand particles or fish. The SRP Sonar operates at 2MHz with a 1.1° conical beam to give precise range and bearing information over the scanned area which may be up to 360°. Typically the SRP Sonar is mounted horizontally near to the seabed and scans a cross-section of the seabed over an angular range of 120°. A data logging version is available with a built in hard disk for remote data gathering. The transducer is enclosed in a µPVC "boot" with no external moving parts for complete environmental protection.

Sand Ripple Profiling Sonar

The sand ripple profiling sonar is mounted horizontally and gathers data over a section of the seabed as shown above. The data is processed to record the profile of the sand ripples at intervals as they are transported underneath the sonar by the tidal flow. The image above was created from a time series of ripple profiles recorded in the Delta flume in Holland. The gap in the data was for synchronisation purposes. At around 70 minutes the waves in the flume were switched off after which time the ripples remain static. The Sand Ripple Profiling Sonar may be supplied either as a slave scanning unit or as an autonomous logging version with built in hard disk for data storage. The slave scanning version is controlled by an RS232 link from a master host computer. The host computer sends commands to control the sonars transducer position and sampling parameters and receives digitised data representing the amplitude of the echo returns for each step position of the transducer. The autonomous version is powered from an external 12v battery supply and has been engineered to take the minimum possible current when powered up but not scanning. The unit may be programmed in the laboratory by connecting a 12v battery and an RS232 lead to a PC running Windows. When programming is complete the unit draws very little power from an internal backup battery until its activation time. The sonar waits until the external 12v supply is present before attempting to capture data at its pre-programmed rate. If required, changes to the units program may be made in the field by connecting a portable PC via the RS232 input. At the end of the deployment period the internal hard disk may be removed and connected to a PC to quickly upload the captured data. Should the external power fail before the logging sequence is complete the data captured up to that time will be preserved. The acoustic beam pattern, operating frequency and sampling speed To verify the accuracy of the sonar system a plaster have been specially selected for the purpose of accurately recording sand cast of a sand ripples was manually surveyed to produce ripple profiles from a position close to the seabed. the uppermost image shown above. The Sand Ripple Profiling Sonar was then set up to scan across the plaster Images processed and presented by the cast at 10mm intervals which produced the lower image.
