Applied Acoustics’ new USBL underwater tracking system is making its first appearance at Seawork in June. Called the Easytrak Alpha, it is the introductory and most compact of their range of subsea tracking systems.

Ideally suited for small ROV operations or basic diver tracking, Alpha is a condensed and cost-effective system for monitoring close range subsea targets.

The Alpha system is centred on a desktop command console connected to the submerged transducer and to the host PC via a USB port. With its own internal GPS receiver, Alpha calculates the target’s position as well as its range and bearing. With the ability to offer hemispherical tracking, Alpha is ideal for shallow water applications from small work boats in coastal waters, estuaries and lakes. A fully portable version with integral computer and display will also be available by the summer of this year.

Alpha joins other Easytrak systems in a range of subsea tracking units from Applied Acoustics that offer true flexibility in operation, including a rack-mounted and spread spectrum model. The addition of a wide range of transponders for positioning and release completes the versatility of the USBL systems on offer.

Many Applied Acoustics’ tracking systems are in use across the globe by commercial marine survey companies, oceanographic institutions and defence industries, all supported by a network of overseas agents.

Established in 1989 and based in Great Yarmouth, UK, Applied Acoustics designs and manufactures subsea positioning and USBL tracking systems, and marine seismic power supplies for offshore survey companies, defence and oceanographic institutions. A worldwide network of representatives ensures customer service on a global scale.

Applied Acoustics launched a powerful new seismic energy source at Oceanology. An extension to the range of market leading seismic power supplies, the CSP-S12000 features a maximum output energy level of 12000 joules, bringing a new dimension to shallow seismic reflection surveys.

Applied Acoustics launched a powerful new seismic energy source at Oceanology. An extension to the range of market leading seismic power supplies, the CSP-S12000 features a maximum output energy level of 12000 joules, bringing a new dimension to shallow seismic reflection surveys.

Designed for use specifically with the upgraded 12KJ Delta Sparker, the CSP-S12000 has been created following customer demand for increased seabed penetration and operations in deeper waters. With its fast charge rate of 2500 Joules per second, the new CSP-S can operate at maximum power once every 5 seconds, allowing surveyors access to geology previously difficult to profile with portable, surface towed equipment.

Although the CSP-S12000 is the largest unit in the company’s range of geophysical power supplies, it still fits comfortably within a single 21U robust housing, removing the need for separate enclosures for the capacitor banks. This single box solution also gives the system portability, and the ability to be transferred between vessels of opportunity.

Technical Manager Neil MacDonald explained, “We’ve many CSP units working throughout the world both in coastal waters and deeper out to sea providing reliable sub-bottom profiling data for a variety of applications, so this new unit will provide the valuable extension to that range that geophysicists need.”

In addition, the company has invested in a spectacular new 6000m pressure test tank which will allow it to develop products for full ocean depth operations.

“The successful launch of several new products in recent years has meant our production facilities have been rather congested,” explained Managing Director Adam Darling, “but now with much more space we can offer a greater product range, shorter lead times and more products from stock.”

The staff have worked hard and a healthy order book reflects their efforts, so I’m delighted we can step up to provide an even better service in the months ahead.” he added.

Applied Acoustics was established in 1989 and now manufactures a wide range of positioning beacons, USBL subsea tracking systems and seismic sub-bottom profiling equipment used by commercial companies and academic institutions worldwide. Their latest new product, the rack-mounted, spread spectrum Easytrak Nexus was launched recently at Ocean Business in Southampton.

The new facility was officially opened by Norfolk MP Tony Wright on April 23rd with local VIPs, customers and suppliers invited to toast the company’s success.

Applied Acoustic Engineering launched its latest USBL tracking system at Ocean Business in Southampton, UK, in April. The new system, Easytrak Nexus, represents the latest in a series of innovative developments in subsea acoustic tracking by the company.

Applied Acoustic Engineering launched its latest USBL tracking system at Ocean Business in Southampton, UK, in April. The new system, Easytrak Nexus, represents the latest in a series of innovative developments in subsea acoustic tracking by the company. Now incorporating Spread Spectrum Technology, Nexus combines its high accuracy performance with versatility and ease of operation.

The rack-mounted Easytrak Nexus determines the position of a dynamic subsea target through the transmission and reception of acoustic signals between the submerged transceiver and the target beacon. By incorporating Spread Spectrum Technology, the frequency of the transmitted signal is able to be varied, reducing its susceptibility to interference and enabling the calculation of accurate positioning information. Spread Spectrum Technology also rejects unwanted reflected signals that have made operating in challenging locations such as ports or harbours difficult in the past.

As with all Easytrak systems, Nexus works with a variety of underwater targets and beacon types including Pingers, Responders, Release and Positioning Transponders. Furthermore, Nexus operates in both traditional ‘tone-burst’ and new Spread Spectrum modes. The Spread Spectrum (SS) Beacons include an enhanced 1000 Series with a depth telemetry option and a Bi-directional Spread Spectrum version for improved range stability. With low-power consumption the bi-directional Spread Spectrum beacons can be connected to peripheral devices subsea to send back digital data, for example current flow or heading, as well as simultaneously being used as navigation transponders.

Nexus has a built in PC running embedded Windows XP with a solid state HD. The positioning information is displayed on a separate monitor where activity of up to ten subsea targets within a specified operating area can be viewed. These targets can be Applied Acoustics’ beacons or those operating in the same frequency range from other sources.

Applied Acoustic Engineering’s range of sub-bottom profiling equipment has recently won critical acclaim during a number of operations in the harsh working conditions north of the Arctic Circle, firstly as part of a research study by the University of Bergen and secondly in the search for hydrocarbons beneath the seabed.

Applied Acoustic Engineering’s range of sub-bottom profiling equipment has recently won critical acclaim during a number of operations in the harsh working conditions north of the Arctic Circle, firstly as part of a research study by the University of Bergen and secondly in the search for hydrocarbons beneath the seabed.

Scientists from Bergen, Norway, have been conducting studies to determine the origin of the Alpha Ridge north of Greenland which required them to obtain seismic data from the seabed underneath autonomous drifting buoys placed on multi-year ice. Personnel from the university had developed their own sparker sound source to suit their specific requirements, but needed an energy supply to operate remotely, in sub-zero temperatures, for a period of approximately 6 months, recharging itself from its own power supply.

Applied Acoustics’ technicians, in conjunction with the university, tackled this challenge by developing a novel seismic energy supply capable of firing a 4.8KJ shot using energy harnessed from the sun. A series of solar cells were incorporated into the unit to recharge the capacitor banks easily and sufficiently, creating a viable and environmentally friendly way round what could have been a major obstacle. The successful arrangement meant that with the buoy drifting at an average speed of 5km/day, the system could fire the sparker every 50m of movement.

The reflected seismic energy, received by a single hydrophone, was digitised and recorded, and sent to Bergen via the Iridium Satellite Network. This enabled the University’s scientists to monitor the operation remotely, returning to the region to retrieve the equipment at the end of the project. Three of these drifting seismic buoys are planned for further deployment in the Spring of 2009.

Elsewhere in the Polar region, Applied Acoustics’ geophysical capabilities have been put to the test in a very different way. Their 6000J Delta Sparker with CSP-S energy source have been utilised in geohazard surveys off the northern Alaskan coast to establish the presence, or not, of shallow gas, active faulting and potential hydrate zones. The Ultra High Resolution (UHR) multichannel seismic surveys utilised a 48-channel streamer at 6.25m spacing in conjunction with the multi-tip Delta Sparker array.

The deployment of the CSP-D and Delta Sparker system offered speed of mobilisation as it required only a two-man operation and a readily available single-phase generator on a vessel of opportunity rather than a cumbersome air compressor and air-gun arrangement on a dedicated platform.

The Automatic Variable Input Power (AVIP) circuitry of the CSP-S also proved important. By smoothing the input voltage to the energy source, a soft start is provided which gradually increases the power output, reducing the load on the equipment and keeping generator requirements to a minimum.

The project was mobilised in the western Alaskan port of Nome in October 2008 and in order to maximise weather conditions the survey was performed ‘single pass’ with good quality high resolution data achieved.

Applied Acoustics have recently returned from a police diving conference where the latest equipment and techniques for policing maritime operations were discussed.

Applied Acoustics have recently returned from a police diving conference where the latest equipment and techniques for policing maritime operations were discussed. Gavin Willoughby, Sales Manager, gave a presentation about Easytrak, the underwater tracking system which can provide police diving teams with vital underwater location information.
Easytrak is used to plot targets, plan the route to a specific seabed or lake location of interest while the divers’ path is monitored on shore or on a vessel above in real-time. Gavin explained, “Underwater dive operations are fraught with difficulty and one of the biggest challenges is knowing where you are, where you’re going and where you’ve been. With Easytrak on the team it’s possible to save a lot of time during a search – plus your colleagues know exactly where you are, so it adds to your safety.”

Applied Acoustics have added a further streamer hydrophone to their range of sub-bottom profiling products. Up to now the company has offered standard streamer hydrophones with 1-8 or 20 element designs but from July it is introducing a 12 element hydrophone spacing...

Applied Acoustics have added a further streamer hydrophone to their range of sub-bottom profiling products. Up to now the company has offered standard streamer hydrophones with 1-8 or 20 element designs but from July it is introducing a 12 element hydrophone spacing, with the array calculated to offer the optimum resolution and penetration for either sparker or boomer applications.

The length of the hydrophone streamers, as with the other variants, remains at 4.5m with a robust 50m tow leader as standard, but the elements are spaced at 250mm. Extensive trials proved this was an ideal specification to bridge the gap between earlier models.

Applied Acoustics supply complete seismic sub-bottom profiling systems including the Seismic Energy Source, the Seismic Sound Source (boomer or sparker) as well as streamer hydrophones so can provide the best package of components tailored to each application. Several hundreds of these systems are in use worldwide by marine survey companies, government departments and academic institutions.

Applied Acoustics, based in Gt.Yarmouth UK, has been manufacturing sub-bottom profiling systems for over 15 years. With advances in technology the company has been able to steadily enhance its product range to meet the ever increasing demands of the industry as regards both performance and safety.

Applied Acoustics, based in Gt.Yarmouth UK, has been manufacturing sub-bottom profiling systems for over 15 years. With advances in technology the company has been able to steadily enhance its product range to meet the ever increasing demands of the industry as regards both performance and safety. For example, the discharge mechanism has evolved from a mechanical device to a solid state switch and the mains supply demand has improved due to the efficiency and averaging rate of the charger. A very recent development, the ‘Dual Voltage Setting’ adds extra versatility by enabling the operator to ‘tune’ the boomer to a lower operating frequency and thus obtain both increased penetration and resolution. Across the product range, output current is monitored shot by shot for fault conditions. Operator safety has always been a top priority so several dual layer features are incorporated to ensure very high safety standards are met.

In the past year alone the company has launched three new Seismic Power Sources; the CSP-D and CSP-P with their special dual voltage output and the CSP-S, a compact ‘all in one’ 6000 Joule power source.

Launched at Oceanology International in London in March, the CSP-S provides both requirements geophysicists have when examining the subsea sediment layers; high resolution, shallow penetration or low resolution, high penetration. It operates both with lower powered boomer plates, such as the AA300 boomer as well as the 6000J sparkers.

Applied Acoustic Engineering is launching its latest Beacons at Oceanology International. The new range, the 1000 Series, is a more electronically sophisticated product with improved reliability. Clever engineering design has also made the new product simpler to use.

Applied Acoustic Engineering is launching its latest Beacons at Oceanology International. The new range, the 1000 Series, is a more electronically sophisticated product with improved reliability. Clever engineering design has also made the new product simpler to use. The Channel Selector switches have gone and in their place is digital control from an external Smart Switch.

The palm sized Smart Switch, with direct connection to the beacon, is packed full of useful electronic circuitry enabling the device to perform a multitude of important tasks in addition to transponder configuration. These include battery diagnostics, trickle charge/fast charge monitoring & control, and depth telemetry selection. Easy to use, the small device provides a smooth and efficient set-up and provides valuable operational information on the clear LCD screen. The
new 1000 Series can also be configured direct from a PC.

“Using our years of experience and useful feedback from our customers we knew exactly what was required when we started designing this product, “ said Neil MacDonald AAE’s Technical Manager, “so we’ve perfected the set-up function and provided the operators with really useful data - just what they need in the field. Even the firmware can be updated remotely via the internet.

“This is an extension to our product range, a means by which we can cater for all tastes, as the 900 Series of beacons will retain their strong role in our product portfolio.” he added.

The addition of a standard 5-pin bulkhead connector, offering pin-for-pin compatibility, improves the versatility and worldwide appeal of the product.

“This is a important new product for the company, ”said Gavin Willoughby, Sales Manager. “The quality of our products and our engineering excellence is recognised across the globe, so Oceanology International will provide us with the perfect platform to let our customers know about this exciting development.”

Applied Acoustic Engineering proudly announce the launch of their new range of CSP Seismic Energy Sources, the latest in a long line of products from the company constantly setting new industry standards for performance...

Applied Acoustic Engineering proudly announce the launch of their new range of CSP Seismic Energy Sources, the latest in a long line of products from the company constantly setting new industry standards for performance. Developed with their vast experience and taking advantage of new improved technologies, the CSP-D range is set to become the benchmark ‘workhorse’ seismic power supply.

Along with an increased energy output, the innovative feature of the CSP-D is its unique dual voltage output, giving the product extra versatility. By adjusting the output, switchable on the front panel, better penetration can be achieved from the boomer plate sound source, a feature previously only obtainable to the same extent with sparker assemblies.

The other notable feature of the CSP-D (as with some other units from AAE) is the incorporation of a special ‘slow-start’ feature. This is a means of gradually increasing power output to ease the load on the sound source, so helping to avoid any potential interference with marine mammals.

The new CSP-D is available with a charging rate of 1500 J/second in three variants producing up to 700J, 1200J or 2400J per shot respectively.
