Overview

The WGT functionality enables Wave Glider to acoustically collect data from large arrays of seabed instruments in a highly cost-effective manner without the need to deploy a traditional surface ship to perform this operation. Instead, Wave Glider is controlled remotely from a shore station via Iridium satellite communications.

The WGT is capable to be used with directional transducer options for operating in both Medium Frequency (MF) (20-34 kHz) and Lower Medium Frequency (LMF) (12-20 kHz) bands to suit different seabed instruments and is fully Sonardyne Wideband® 2 compatible.

The WGT is tightly integrated into the Wave Glider vehicle communications and power systems thereby providing many of the standard acoustic commands and features associated with Sonardyne 6G® products.

Data is passed by Wave Glider to the Iridium satellite system for onwards transmission to the user in near real time.

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.

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.
