Overview

Its high power output and Wideband 3 signal processing offers improved operating range and acoustic performance in challenging conditions such as when deployed from noisy vessels or in multi-path environments.

The internal Lithium-ion rechargeable battery pack minimises the supply current for long dunker cables. It also enables relocation of the dunker if the cable is cut.

The robust AGP connector on the Dunker 6+ is identical to the ROVNav 6+ and HPT USBL for compatibility and to reduce spares.

Dunker 6+ LBL and telemetry transceiver is fully compatible with our modem and sensor logging instruments such as AMT and Fetch , allowing it to be used to retrieve data or configure logging regimes. It can also be used to release the RT 6 range of acoustic releases.

The Dunker 6+ system consists of 100 m of cable on a stainless steel cable drum with brake and locking mechanism. The 10 m deck cable between the 48 V Surface Interface Unit (SIU) and the cable drum allows the drum to be conveniently located. The connection to the cable drum is via an easily replaceable 8-way SubConn.

Optionally, an RT 6 topside kit with 30 m of cable is available in a carrying case without a cable drum.

Overview

The ESH is the network interface between the in-water acoustic instrument, GPS and the PC that runs the positioning software.

In addition to accurately time-stamping incoming data from external devices such as gyro, VRU and GPS it provides power and communications for acoustic transceivers.

The ESH includes a time source that can be linked to an internal or external GPS PPS input, allowing the Ranger 2 system to accurately time-stamp incoming data from external devices such as gyro, VRU and GNSS to UTC.

Wi-Fi connectivity allows connection to a PC using a Wi-Fi adapter.

Overview

HPT 2000 offers significant advantages for survey operations in coastal and near shore regions where simultaneous positioning of transponders attached to transition zone/ocean bottom seismic cables at high elevation tracking is required in low noise environments.

The advanced multi-element processing enables transponders to be positioned more precisely, more quickly and more robustly due to improvements in signal processing algorithms. When used as part of a complete Mini-Ranger 2 USBL system, heading and inertial navigation sensor, class leading performance is achieved.

At a glance

• Use it with Mini-Ranger 2 USBL
• Optimised for high elevation tracking in shallow water
• Easy to deploy on temporary over-the-side set up
• Ethernet comms for fast position updates
• Excellent corrosion resistance

The integral MTi-30 Xsens sensor provides pitch, roll and heading data that automatically compensates for the dynamic motion of the vessel, removing the need for an external sensor and pre-use calibration.

Manufactured in Aluminium Bronze, HPT 2000 is intended to be fitted temporarily or permanently to a vessel’s through-hull or over-the-side pole.

The full hemispherical coverage optimises performance in shallow water environments boosting transmissions and receive sensitivity in the horizontal axis.

Ethernet connectivity enables the system to function over existing ship network wiring for rapid installation.

Overview

When it comes to USBL and LUSBL transceivers, one model does not fit all situations and vessels. For Ranger 2 and Marksman installations, our High Performance Transceiver (HPT) is available two primary configurations.

HPT 5000
HPT 5000 offers full hemispherical acoustic coverage so it’s a popular choice for tracking multiple targets  (ROVs, AUVs, towfish, seafloor sensors) over a wide range of depths and elevations. The unit is also suitable for dynamic positioning reference on survey, research and offshore support vessels.

HPT 7000
HPT 7000 is engineered for ultra-deepwater operations, tracking targets far below (rather than to the side) of a vessel, and also high vessel noise operating environments, as those typically encountered on DP drilling and construction where aeration from thrusters is liable to cause signal interference.

Both models of transceiver fully support 6G LBL operations using Fusion 2 LBL software. They are also highly capable acoustic communications modems, able to interrogate, command and recover data payloads from deployed Sonardyne instruments including AMTs and Fetch. Supporting telemetry rates of up to 9,000 bps minimises the time a vessel has to wait on location to recover data, as well as supporting LBL operations.

HPT 5000/7000s are also available in Gyro USBL configurations offering calibration-free installation and use.

At a glance

• Use with Ranger 2 USBL and Marksman LUSBL systems
• Can also be used to communicate and harvest data from Sonardyne sensors
• Hemispherical (HPT 5000) or directional (HPT 7000) arrays to suit your vessel and application
• Can be deployed other-the-side, through-tube or through-hull
• Suitable for new-build vessels or USBL/LUBL upgrade for your existing vessel

All HPTs are built on our 6G technology platform with multi-element processing to enable transponders to be positioned more precisely, more quickly and more robustly due to improvements in signal processing algorithms and array design.

Functionality such as ‘Discovery Mode’ enables vessels equipped with Ranger 2 and Marksman to enter an offshore area and automatically detect previously deployed transponders (including their configured address and channel), making simultaneous operations using shared seabed arrays possible.

Manufactured in aluminium-bronze, HPTs are intended to be fitted temporarily or permanently to a vessel’s through-hull or over-the-side pole. HPT 5000s (including Gyro USBL 5000s) have also been fitted to large USVs for uncrewed missions controlled from over-the-horizon.

For specialist applications, inverted USBL, LMF frequency and extreme depth range HPT transceivers are also available. Please get in contact to discuss your requirements.

Overview

Using a superfast processor to handle intensive workloads, Marine Computer is designed and configured to provide you with the best possible experience when using our suite of navigation, positioning and imaging software products, leaving you to concentrate on the job in hand.

However, you don’t have to be using Sonardyne software to use one. If you’re in the market for a robust and easily configured computer to run third-party software applications onboard your ship, survey boat or unmanned craft, Marine Computer is the perfect choice.

That’s because it’s certified to EN60945 and DNVGL-CG-0339 standards which means it meets regulatory requirements to be used on ships’ bridges and is able to withstand harsh operating environments and where constant high temperatures are present.

At a glance

• Choice of desktop or 2U rack mount configurations
• Fanless and temperature tolerant design withstands harsh marine operating environments
• Certified to EN 60945 and DNVGL-CG-0339 – use it on your bridge
• Intel Tiger Lake Core CPU runs intensive applications with ease
• Desk, console and rack mounting options
• Wide operating temperature range

Fanless computers like the Marine Computer are perfect for use in dirty or dusty marine environments where actively cooled systems could quickly clog up, overheat and fail. Inside is an Intel® Tiger Lake Core i5-1135G7 2.4 Ghz processor and 512 GB industrial grade solid state disk. SSDs have no moving parts so are faster and more reliable than traditional hard disk drives. Temperature tolerant components contribute to its impressive wide operating temperature range.

All this makes the Marine Computer an extremely versatile and reliable tool in virtually any marine installation condition: desk mounted, in a small survey boat; within a ship’s bridge console; or, when supplied with a custom 2U chassis, mounted in a server room rack.

Overview

With a high manufacturing tolerance combined with a pop-up ‘tell-tale’ flag that provides visual confirmation the transponder is precisely docked, our stab and receptacle saves times and improves the accuracy of subsea construction.

Using our stab and receptacle, the traditional method of rotating of a stab in a hub during metrology operations to determine stab-to-receptacle slop, can be eliminated. With this time consuming task removed, acoustic metrologies have the potential to be completed in less than six hours.

The tolerance of the design allows for 0.1° for heading and 0.01° for pitch/roll which is the same quoted error of a calibrated Gyro Compatt 6. This improves the results of the metrology or other positioning tasks and reduces the need for error determination of the stab/receptacle.

At a glance

• Allows you to accurately align transponders on structures
• Perfect for installation during metrology campaigns
• Allows transponders to be quickly removed and re-installed using ROV
• Two stab variants available to bolt onto either Inclinometer Compatts or Gyro Compatts
• Can be fitted on the back deck using existing hole patterns
• Tell-tale indicator confirms the stab is fully docked into the receptacle

The receptacle is designed to bolt into the eight bolt hole pattern of the industry standard 8” AWWA Class D flange. This allows the user to either bolt this flange onto the structure or to provide bolt holes in the structure itself. After dimensional control techniques to determine the relationship of the bolt holes in relation to the structure points of interest (jumper hubs, CRP, spool flanges, etc), the receptacle can be bolted in with known offsets to these points. This allows fast and precise inferred metrology to one or multiple hubs or flanges from a single receptacle.

The receptacle features a 45° cone in which the stab sits. This reduces the possibility of debris building up on the interface between the two and allows for a more precise connection due to the point of contact being exactly circular regardless of any small expansion/contraction effects.

The stab also features an alignment bar rather than alignment pins to aid docking and provide superior heading alignment. An O-ring on the stab shaft assists in ensuring the two are precisely mated.

Overview

Mini-ROVNav 6+ is designed to be significantly lighter and smaller than our standard ROVNav 6+ instrument, whilst providing full 6G LBL capabilities.

This makes it particularly suitable for inspection-class ROVs as well now uncrewed surface vessels (USVs) which can be configured to undertake routine LBL operations over-the-horizon from your survey vessel.

Its full support of  Wideband 2 signal processing techniques offers long range and robust acoustic performance in challenging conditions such as on noisy vehicles or in multi-path environments.

At a glance

• Use it with Fusion 2
• Perfect when ROV space is limited
• USBL mode for emergency relocation
• Lightweight and easy to install
• Modem mode for data recovery from AMTs and Fetch instruments

Mini-ROVNav 6+ is also a fully compatible USBL responder or transponder compatible with Sonardyne Wideband 1 and 2 USBL systems and HPR 400. The internal Li-ion rechargeable battery pack also enables emergency transponder mode, so if the umbilical and therefore power is cut to the ROV it can still be located using a vessel equipped with a USBL system.

The integrated omni-directional MF transducer has a hemispherical beam pattern which is ideal for acoustics to an array and to a vessel alike.

Mini-ROVNav 6+ is fully compatible with our modem and logging equipment such as AMT and Fetch products, allowing it to be used to retrieve data or configure logging regimes. Data rates of between 100 to 9,000 bps user data rates can be supported depending on the environment.

Overview

NSH is a 2U high rack-mounted unit that is the interface between your in-water deployed transponders, vessel-mounted transceiver and Marine Computer which runs Ranger 2 USBL or Marksman LUSBL software applications.

In addition to accurately time-stamping incoming data from external devices such as gyro, VRU and GNSS, the NSH also provides power and communications for ship-borne acoustic transceivers such as HPT 5000 or HPT 7000.

A range of hardware interface cards are available for interfacing Sonardyne transceivers and external sensors. By simply plugging these cards into the rear of the unit, the role of the Navigation Sensor Hub can be transformed from supporting simple to complex acoustic operations.

The NSH includes an IEEE-1588/PTP precision time source that can be linked to GPS PPS input. Multiple NSHs automatically synchronise their clocks. All incoming data is time stamped to sub-microsecond accuracy – outgoing transmissions and triggers can be scheduled to the same precision.

Depending on the application (DP, drilling or survey operations), the NSH can be configured in stand-alone, dual-independent or dual-redundant modes.

At a glance

• Use it with Ranger 2 and Marksman LUSBL systems
• Interfaces vessel’s acoustic instruments with operating software
• Time stamps gyro, VRU and GNSS data
• Offers up to 16 serial ports (RS232/485)
• Configurable for dual independent applications

Overview

Acoustic release transponders are a vital piece of ocean equipment – relied upon by energy, defence and science users to moor valuable equipment strings for years at a time, and when commanded to do so, reliably return equipment and logged data to the surface.

Transponders need to be tough, reliable and easy to work with. RT 6-6000 meets these requirements.

Part of our new range of acoustic releases, RT 6-6000 combines the extensive mechanical design track record of our renowned ORTs and DORTs with the flexibility of our 6G platform, resulting in enhanced battery life and perhaps most significantly, compatibility with our Ranger 2 USBL family

With RT 6-6000, you can use your vessel’s Ranger 2 USBL to deploy, track, locate and command the instrument – removing the need for a separate topside unit. If you don’t have access to a Ranger 2 USBL, our rugged and lightweight Deck Topside with an over-the-side dunker is all you need to both configure and command RT 6-6000s.

At a glance

• Tested, loaded, deployed and released using Deck Topside
• Also works with Sonardyne Ranger 2 USBL to deploy, track and command in very deep water
• Highly reliable release mechanism design and thousands are in service globally
• Working Load Limit 1,275 kg (4:1)
• Depth rated to 6,000 m
• External battery disconnect to maximise battery life with no need to open unit
• Compact and rugged design

RT 6-6000s are most commonly used to anchor oceanographic moorings to the seabed. However, their compact size and compatibility with Ranger 2 makes them ideal for incorporation into instrument frames or lowered platforms to enable deployment of sub-system packages.

Standard features include a Working Load Limit of 1,275 kg (at 4:1) and a spring-assisted release mechanism. RT 6-6000 is compatible with our standard tandem and high-load release frames for scenarios requiring a higher WLL. Speak to us about your requirements as custom frames are also an option.

A battery disconnect fob is located on the transducer and uses an internal magnetic switch to electronically disconnect the battery when not in use. This means you do not have to open the unit to manually disconnect the battery, saving time and reducing the risk of incorrect re-assembly.

RT 6-6000s use the same trusted spring-assisted release mechanism that has been in service for many years and used on thousands of Sonardyne transponders globally.

Overview

Designed for the deployment of our range of USBL and modem transceivers (including Gyro USBL) and Sentinel IDS sonar heads, our through-hull machine provides survey grade rigidity for use with USBL systems up to seven knots (total through water speed) with the ability to survive short duration exposure to higher speeds.

Where the pole is required to be longer than three metres, or where operational water currents may reach 10 knots (total through water speed), the pole must be installed using our heavy duty installation requirements. For specialist or demanding applications, machines of this general type can be custom engineered to suit customer specific requirements. Please consult us if your application has an operational through water speed greater than seven knots.

The machine consists of an electronically controlled but hydraulically operated pole running through a sealed bearing section. A service section (or sea chest) is provided with inspection door to allow fitting and servicing access to the transceiver or sonar head. It is designed to fit on to DN350 and DN500 gate valves however, other gate valves are also supported.

The machine can be controlled from a main control panel or locally at the machine. A bridge control is also available as an option. Hydraulic control of the gate valve is provided as an option. The hydraulic power pack and main control can be mounted remotely if the machine is to be configured for Zone 1 Ex rated classification.

The standard machine can be configured to the meet individual vessel requirements by changing the height of the machine and providing adaptor flanges for different size or specification gate valves. We can provide detailed application advice on positioning, installing and commissioning your machine.

At a glance

• Allows you to deploy instruments from your vessel with maximum performance
• Optimised for Ranger 2 USBL (including HPT modem configurations), Marksman LUSBL, Modem and Sentinel IDS systems
• Choice of through-hull, through-tube and over-the-side designs
• Global track record on all types of vessel: new build and retrofit
• Options for permanent or short term installations on vessel-of-opportunity

Over-the-side
Our modular, over-the-side deployment machine is for vessels where through-hull deployment is not available or practical, or where a temporary installation is required on a vessel-of-opportunity. The design still provides survey grade rigidity without the high cost of dry docking and fitting a gate valve. It can work at operational speeds of up to five knots without degrading USBL positioning performance and to have a survival speed of up to ten knots.

Based on a pivoting sectional pole, the system can be supplied with either a hull or deck mount for the pivot, depending on the vessel arrangement. A brace/lock assembly positioned near the water line and three or four pole sections bolted together to form the arm such that the transceiver on the end of the arm is positioned below the hull by at least 1.5 m. The lower portions of the sectional pole are faired to mitigate against vortex induced vibration which can reduce performance.

The system is not limited to deploying Sonardyne instrument. We can custom engineer adapters for the end of the pole to accommodate third-party sensors.

Through-tube
Popular on very large vessels including drilling rigs, our through-tube deployment machine consists of a hydraulically operated pole, a sealed bearing section and a sea chest service section, with inspection door. The whole machine sits on a gate valve which in turn is mounted on the flange of a through hull penetration pipe.

The ideal deployed length is dependent on your particular application, but in general terms it is best to minimise the deployed pole length to achieve a specified acoustic performance. Typically, a length of between one and three metres below the hull has been found to be acceptable. The pole is very rugged and is designed to be highly resistant to vibration caused by vortex shedding. Operational speeds of up to ten knots through the water may be achieved safely with the ability to survive short duration exposure to higher speeds.

We provide detailed application advice on positioning, installing and commissioning the machine. The sea chest, when the gate valve is closed, provides easy access to the retracted transceiver or sonar for service and inspection purposes. The gate valve also allows the machine to be removed without dry docking. An optional hydraulic drive for the valve is available.

The machine can be controlled from a main control panel or locally at the machine. A bridge control is also available as an option. The hydraulic power pack and main control can be mounted remotely if the machine is to be configured for Zone 1 classification. The standard form of machine can be simply configured to the meet individual vessel requirements by changing the height of the machine and providing adaptor flanges for different size or specification gate valves.

For specialist or demanding applications, machines of this general type can be engineered to suit your specific requirements.
