Tune Your Dredging The RheoTune can help you optimise maintenance dredging and guarantee safe port access

2

13.06.07

Newly-developed RheoTune is the state-of-the-art successor to Stema Survey’s DensiTune silt density probe, a device with a proven track-record in nautical depth assessment. Ongoing research into tuning fork response (shearwave propagation theory) in fluid and semi-solid muds has led to the development of an in-situ measurement system that can directly assess rheological characteristics. A specialist in silt measurement systems, Stema has succeeded in turning advanced theory into a handson measuring device providing fast, accurate vertical rheological profiles of both yieldstrength and viscosity – information directly relevant to nautical depth assessment. RheoTune is fully backward

compatible with DensiTune and can simultaneously provide vertical mud density profiles. Although mud density is not the only criterion

determining the effect on a ship’s manoeuvrability – and the mythical 1.2 ton/m3 criterion may not be correct in all circumstances – it’s essential information when budgeting maintenance dredging quantities. New TDS (tons dry solids) calculation functionality will further enhance this process. RheoTune can be supplied with an intelligent electrical winch system. External sensor input like sounding depth and speed over ground enable fully-automated operation. Variable winch speed combines fast hoisting with accurate measurement to ensure the highest productivity. What’s more, full integration with the Silas acoustic profiling system converts an echosounder system into a real-time density mapper. Rapid tracing of critical locations that require in-situ probing or immediate dredging are all easily integrated in your regular survey procedures. Integration with multibeam sonar data can provide real-time nautical depth maps. Please feel free to contact us and discuss the possibilities for optimising your dredging efforts. You will be in good company – our systems serve leading harbour authorities, dredging contractors and research institutes worldwide, including the US Corps of Engineers, Port of Rotterdam, WSA Germany, Bristol Port, Shanghai Dredging, Van Oord and the University of Rio de Janeiro.

VOSTA LMG – all your dredging needs Supported by a wealth of experience, our priority is to supply the most cost-effective dredging equipment that delivers the best results Dredger engineering and contracting company VOSTA LMG is one of the few firms in the industry capable of designing custom-built and standard dredgers, whilst also providing a complete, in-house range of dredging components. We combine unrivalled product know-how, R&D, extensive experience and outstanding engineering capabilities to meet all your dredging requirements. VOSTA LMG delivers a wide range of standard products for any type of hydraulic dredger, whether it be a newbuild, a refit or an upgrade. And components are made ready for easy onboard installation and integration with the rest of the vessel. VOSTA LMG designs and manufactures tooth systems for use

on dredger cutterheads, dragheads and cutting wheels. Our globallypatented T-Cutter System fully meets modern demands for economy, safety and ergonomics.

How it works Previously, cutterteeth were locked to adapters on the cutterhead using sandwich pins that were mounted and dismounted using large sledgehammers. This tough and time-consuming job came with a relatively high risk of injuries, either caused by the hammers themselves or by steel splinters. The main innovation of VOSTA LMG’s revolutionary ‘third generation’ – or T-series – adapters and teeth is the inclusion of an easy-to-place locking unit that’s pre-tensioned with an airtool to lock the teeth to the adapters.

The dredging world has experienced continuous growth in recent years, and demand for construction activities in ports and elsewhere has increased demand for reliable and highly efficient dredging equipment. At the heart of every dredger lies the dredge pump, an invaluable resource that plays a key role when aiming for high production efficiency. And the reliability, utilization and performance of the dredge pump will dramatically affect a dredger’s performance. Acknowledging all of these requirements, VOSTA LMG developed the VL 500–1200 series of high efficiency single or double-walled dredge pumps designed to deliver high performance, yet at the same time reduce lifecycle costs. Our standardized suction system meets all the following requirements: Multi-purpose operation Standardization of parts Interchangeability High efficiency over the complete design life High wear resistance High operation pressure (up to 30 bar outlet pressure) Low net positive suction head (NPSH) Increased up time Reduced maintenance time Low energy consumption, and Fast delivery time.

Made to measure With our finger firmly on the pulse of state-of-the-art technology, VOSTA LMG is well equipped to deliver the dredge pump system of your choice. Alternatively, we can design a tailormade dredge pump that meets your specific requirements and integrates all our experience and know-how.

Need multiple channels? Up to four high-power transceivers can operate simultaneously from the EA 400. For improved performance, they’re installed close to the transducers and linked to the combined display and processor with a single data cable. The 38 available frequencies span from 33kHz to 710kHz, while a variety of highly efficient transducers is available to suit all your operational needs – from extremely shallow coastal areas to 3,000m water depths.

Invisible Sound Makes Everything Visible Precision hydrographic echo sounding at your fingertips with the EA 400 single beam echo sounder Though acoustic sound transmission is the basic technique for underwater navigation, telemetry, echo sounder and sonar technology, the sea is far from an ideal transmission medium. Acoustic noise and multi-path interference are some of the major concerns, but with over fifty years in the business, we’ve learned to master sound in water and the dark secrets of the deep blue – our EA 400 single beam echo sounder is state-of-the-art.

13.06.07

Common for all is the use of underwater pressure wave signals that propagate with a speed of 1,500m/s through the water. When the pressure wave hits the sea bottom, or another object, a reflected signal is transmitted back and detected. The reflected signal contains information characterising the reflected object. The EA 400, however, can be used for more than one purpose. By connecting a wide range of Kongsberg Maritime or third party

Replay and storage There’s internal storage of all sample data, including all input signals, for replay or export. The replay file can be divided into ‘n’ new files by using the replay dialogue box. Other types of data can also be stored, such as xyz, text and history data.

Efficiency Improvement… QINSy Dredging Want to improve efficiency aboard your vessels? Then 3D visualization of dredging operations is vital – and QINSy, the world’s leading hydrographic data acquisition and navigation package, will meet the high expectations of the dredging industry and its clients QINSy Dredging provides a seamless combination of navigation, profile, 3D and alphanumerical displays to monitor dredging works and ensure that operations are carried out in an effective and efficient manner. Real time updating of the bathymetric survey information with the actual dredge depth, or dumping action, ensures that the dredge crew can optimise their activities, based on the latest seafloor projections. QINSy Dredging supports: Trailer suction hopper dredgers Cutter suction dredgers Hydraulic backhoe dredgers Grab dredgers / wire cranes Side-dumping pontoons and vessels Spreader pontoons Environmental dredgers. In the dredging industry, on-line 3D

applications are not yet widely used and the value is still underestimated. Yet without the use of 3D presentation, dredgemasters have to combine 2D chart information (X,Y and coloured depth information) with 2D (Y,Z) depth information of the dredge tool. Sensors on the dredge head indicate if you hit a high spot.
