Designed to work in any depth

From less than 1 m in the transition and surf zones to 3000 m for ultra-deep-water seismic applications.

Our shallow and deep rated acoustic positioning systems improve the speed, accuracy and efficiency of positioning seabed marine seismic nodes and cables, enabling the positioning of thousands of transponders in parallel with deployment and shooting operations.

The system uses a network of low cost, rugged transponders that can withstand fast deployment through mechanical ‘squirters’ to provide users with an efficient method of collecting the positions of thousands of seabed nodes in real-time.

A typical system comprises of acoustic positioning transponders attached to the seismic node or cable and a vessel or USV based acoustic range only or full USBL transceiver interfaced to a PC running our HydroPos seismic positioning control software application. Third party software applications that incorporate an acoustic control module can also be used with the system.

Once the nodes are deployed on the seabed, the system precisely measures the acoustic range (distance) or 3D position (USBL) from a surface transceiver on the pinging vessel to each transponder to enable its exact position to be established. The range and USBL positioning processes are more accurate than traditional first break techniques, 1-2 m absolute, and can either be conducted during node or cable deployment operations or later whilst shooting.

Transponders

The transponders developed for the system are small and lightweight and are proven to withstand the demanding and varied operational environment of surveys.

Standard features of the popular Type 7815 TZ Transponder include a depth rating of 500 metres, a unique acoustic ‘address’ enabling thousands of units to be laid in a single deployment and battery voltage monitoring to allow users to better plan their maintenance schedules. TZ Transponders operate in the HF band.

The LRT is a release transponder option for this system. It incorporates an acoustic release mechanism and is typically used at rope or cable ends to aid recovery of seabed seismic equipment after shooting is complete.

SST 6 incorporates our Wideband 2 digital acoustic signal processing architecture ensures robust positioning performance with high levels of ranging precision. It can be provided in 1,000m and 3,000m depth rated housings and is fitted with a handy Near Field Communications (NFC) link as standard for programming and battery status checking.

RT 6-1000 is a release transponder option for this system. It incorporates an acoustic release mechanism and is typically used at rope or cable ends to aid recovery of seabed seismic equipment after shooting is complete.

Both SST 6 and RT 6-1000 are MF band transponders, compatible with our family of Ranger USBL acoustic positioning systems.

Transceivers

Two surface transceiver options are available for this system. TZ Transceiver (TZT) is small and lightweight making it perfect for use vessels-of-opportunity and uncrewed surface vessels which are increasingly being used in support of offshore seismic operations. It can operate in the HF or MF frequency band.

TZT is able to interrogate and calculate acoustic ranges to nine TZ Transponders or 95 SST 6 transponders at a time.

HPT 2000 (HF) and HPT 5000 (MF) are USBL transceivers configured to measure range and bearing to TZ Transponders and SST 6 transponders respectively. They are particularly well suited to high elevation tracking scenarios and offers true simultaneous tracking of multiple transponders providing superior position update rates.

Our team is here to advise you which configuration of transponders and transceivers your offshore seismic positioning system should be configured with to meet to operational requirements.

Precise, seamless, robust

Precision engineered, Marksman leverages the strengths of both USBL and LBL acoustics, providing enhanced precision and range redundancy through seabed transponder networks.

Marksman seamlessly integrates with your existing DP system, whether you’re running GE, Kongsberg, MT, Navis, Rolls-Royce or Wärtsilä.

Robust and reliable dual independent hardware configurations provide redundancy to ensure your critical operations can continue even if part of the system becomes unavailable. There is also option of operating in triple redundancy configuration through the augmentation of our inertial navigation technology – known as DP-INS.

DP-INS has been developed to meet regulatory requirements which state that deep water drilling units must be equipped with three independent positioning reference inputs to their DP system. Traditionally, an acoustic positioning system and two separate GNSS systems are used.

However, vulnerability remains should the acoustics be affected by aeration and noise and both GNSS systems simultaneously affected by signal disruption. The latter is particularly common around equatorial regions and during periods of high solar radiation. Marksman removes this vulnerability by reducing the reliance on GNSS.

How Marksman elevates your operations

The Marksman system, built on ground-breaking 6G and Wideband 2 technology platforms, offers a comprehensive solution that combines faster, more robust data transmission with precision acoustic ranging that remains immune to vessel and ROV noise.

This trusted system, widely adopted by leading offshore energy operators in the Gulf of Mexico, Brazil, and West Africa, delivers uncompromising precision and global tracking capabilities at any depth, while seamlessly integrating with DP systems. Its dual and triple redundant configurations, immunity to GNSS disruptions, and extended battery life make it ideal for semi-permanent seabed deployments.

The system excels in mission-critical applications including riser monitoring and dynamic positioning reference, while offering valuable additional capabilities such as acoustic riser angle monitoring, backup BOP acoustic control, and data recovery from seafloor sensors. With its future-proof platform, simple user interface, and proven reliability, Marksman is the premier choice for operators requiring robust performance in demanding offshore environments.

Enhanced efficiency through optimising hardware mobilisation. By consolidating control under one program, you require less equipment offshore, reducing costs and simplifying logistics, as well as saving you valuable setup time.

Built for our latest 6G+ instruments, Fusion 2 unlocks the full potential of Wideband 3 signal technology, ensuring your operations are at the forefront of subsea navigation.

Fusion 2 – fuse your systems for optimal performance

Why Fusion 2 is perfect for your operations

Do more with less – no need to operate two independent software and hardware systems to control your 6G LBL and SPRINT INS – Fusion 2 does it all in a single interface.

Fusion 2 LBL allows you to run calibrations in real time. Meaning you spend less time calibrating and more time collecting the right data, first time.

Lower your start-up costs: for practical, reliable LBL INS, Fusion 2 supports use of our SPRINT 300 with fewer transponders.

Why choose it/us

Backed by over 40 years of LBL system experience, Fusion 2 is the obvious choice for your offshore installation projects. Its 6G+ technology allows centimetric subsea positioning in all water depths. Highly robust and accurate instruments, professionally supported by our in-house engineers and surveyors, have made it the system of choice for subsea structure installations for decades.

Used with products such as GyroCompatt 6+, it provides you with centimetric positioning along with class leading Lodestar gyroscopes for heading, pitch and roll measurements all in a single, easy to deploy instrument.

If your underwater operations require precise measurements, an acoustic metrology system using several Compatt 6+ transponders can be placed in a network on the seabed / structures / hubs. The depths of the Compatts can then be accurately measured and 6G+ Wideband acoustic ranges collected between them.

Fusion 2 enables your seabed transponders to be SLAM calibrated in real-time for easier and faster Sparse LBL operations. And by embedding sensor data with high-update navigation ranging data, there’s no more interruptions to positioning updates at critical moments.

You’ll begin to see the benefits even before your project teams head offshore. Acoustic and INS projects can be configured and checked onshore prior to vessel mobilisation – saving you time, streamlining procedures and helping you to further de-risk operations.

If you need to tailor your operations, Fusion 2 enables multiple computations, comparing different set-ups, allowing you to pick the one you want. Sparse LBL might suit one operation more than LBL and vice versa. Now it’s easy to check, on-site, which works best for you.

"The Kit"/technology/software

For optimal performance, Fusion 2 can be used with a number of our products – including Gyro Compatt 6+, Compatt 6+, SPRINT-Nav, ROVNav 6+ / mini ROVNav.

To further increase operational efficiency, digital signal processing protocol, Fusion 2 is best paired with Wideband 3, which you’ll find inside our trusted 6G platforms, Compatt 6+ and ROVNav 6+.

Wideband 3 gives you sensor data alongside navigation ranging data, providing your operators with real-time positions and sensor data at the same time. This allows the acceleration of update rates by a factor of ten, eliminating latency issues.

For safer deepwater drilling

Designed for use from both Dynamically Positioned (DP) and moored drilling rigs, MRAMS uses our low-risk, field-proven 6G hardware and Wideband 2 acoustic technology to maintain an uninterrupted wireless data link between a rig and BOP, even in the high-noise environments typically associated with drilling operations.

Suitable for real-time monitoring for drilling operations and riser movement, MRAMS provides high update, low latency data updates ensuring you know exactly what is happening during your operations. Unlike expensive cabled solution which are vulnerable to damage, MRAMS is a wireless acoustic solution. Simple and intuitive software provides clear and unambiguous data on a riser’s angle and profile

Designed for use from both dynamically positioned (DP) and moored drilling rigs, MRAMS uses our low-risk, 6G hardware and Wideband 2 acoustic technology to maintain an uninterrupted wireless data link between a rig and BOP, even in the high-noise environments typically associated with drilling operations.

Developed from field-proven components, MRAMS is based on the integration of our USBL acoustic positioning technology and BOP-mounted transponders fitted with high resolution inclinometers. This provides clear and unambiguous data on your vessel’s position and riser angle status.

At a glance:

• Helps prevent costly damage to riser and BOP
• Provides clear information for users to maintain riser angles within operational limits
• Integrated USBL acoustic positioning for DP reference
• Designed for deep water operations
• Standalone system or integrated with Marksman LUSBL

Marine Riser Angle Monitoring System

How it works

MRAMS comprises of four key elements; a Navigation Sensor Hub (NSH) and computer for controlling the transmission and decoding of acoustic signals, a vessel-based HPT 5000 or HPT 7000 transceiver which acts as an interrogator/receiver and responds to commands from the NSH, and a pair of DPTi 6 transponders; one fitted to the riser and one to the BOP.

On command from the NSH, one of three angles can be measured: the riser, the BOP or differential riser/BOP angle. During drilling operations, the riser and BOP angles are continuously measured by each DPTi 6 and the differential riser/BOP angle calculated. The angles are transmitted to the vessel using high speed digital acoustic telemetry, where they are received by the HPT transceiver, decoded, and then displayed on the bridge or drill floor. The vessel’s position and bearing relative to the BOP is also calculated and the information displayed to your DP operator or barge engineer. This data enables them to steer the rig and return the riser flex joint back to vertical.

In addition to its stand-alone capability in accurately monitoring the riser and BOP differential angle during drilling operations, MRAMS integrates seamlessly with our dynamic positioning (DP) reference system, Marksman LUSBL, to provide reliable and accurate vessel positioning for mobile drilling units.

Precision depth monitoring for offshore operations

The Riser Profiling system can be used as a standalone, integrated within a Marksman LUSBL acoustic position reference system, or with a third-party integrated monitoring system.

6th Generation (6G®) DPTi or SMART transponders wirelessly mounted along the length of the riser, provide highly accurate data. These are clamped onto the riser during deployment or installed via ROV subsea. Up to ten transponders are mounted on a riser. Each transponder is fitted with the following sensors:

• High-resolution dual axis inclinometer
• Water temperature
• Pressure and depth
• Optional single point Doppler current meter (speed, direction)

The gathered data is transmitted wirelessly from the transponders using our Wideband 2 acoustic signals to a transceiver on the vessel, eliminating the need for expensive umbilical cables to fitted up each riser.

At a glance

• Designed for monitoring your riser’s integrity
• Helps prevent critical damage during operations
• Removes need for expensive cables
• 6G hardware and Wideband 2 acoustic delivers robust performance during operations
• User configurable update rates

Advanced monitoring for subsea success

Topside software makes changing monitoring regimes easy. You can even set an alarm to activate when the calculated riser angle exceeds a predefined limit.

At the update rate you choose, inclination, current speed and direction, pressure, temperature measurements are requested from each transponder. All data is processed, logged and displayed graphically and numerically on the topside computer software for your instant analysis. When SMART transponders are used, the data is processed within the transponder and wirelessly transmitted to the vessel’s transceiver.

Get the SPRINT advantage

SPRINT gives you:

• Robust performance in challenging subsea conditions
• High-precision outputs for enhanced vehicle control
• Instantaneous start-up without lengthy alignment periods
• Seamless integration with your existing equipment

SPRINT optimises acoustic aiding data from USBL, LBL, Doppler Velocity Log (DVL) and pressure sensors, improving position accuracy, precision, reliability, and integrity. It extends the operating limits of your vessel’s USBL and enhances LBL efficiency by enabling sparse seabed transponder arrays. All while reducing operational time and vessel costs.

Choose your SPRINT

• SPRINT 300: Perfect for dual ROV and survey use, standalone ROV guidance, and mid-water station keeping. It’s the most cost-effective subsea INS available, with less than 0.1° Sec Lat Heading accuracy.
• SPRINT 500: Ideal for your demanding multibeam survey operations. Supports tightly integrated sparse LBL range aiding from Sonardyne 6G transponders, with automatic pressure and swell compensation.
• SPRINT 700: Our highest-performance INS system, designed for your most challenging subsea survey tasks. Supports mobile laser mapping and acoustic inertial metrology with tight integration to Sonardyne acoustics.

The technology

Inertial navigation is inherently self-contained and robust with very good short term accuracy, but it can drift over time. Therefore, the SPRINT INS is supported by complementary acoustic positioning to provide long term accuracy and robustness. This significantly reduces operational delays during periods of challenging subsea acoustic conditions such as aeration and noise. The precision and update rate of the output allows greater subsea vehicle control and makes SPRINT suitable for ROV station keeping.

SPRINT shares a hardware platform with our Lodestar AHRS and runs both AHRS and INS algorithms concurrently. This allows instant INS start or restart upon receiving a position update, eliminating the lengthy ‘alignment’ period common in other systems. The system monitors AHRS and INS orientation separately to assess its health. All calculations are performed internally, protecting against communication issues. The system maintains a 15-day backup of navigation and raw data on an onboard SD card, while topside software concurrently logs all data, ensuring data integrity.

DVL and AHRS/INS

Our Syrinx DVL provides tight beam-level aiding to SPRINT, giving superior positioning performance even with partial beam availability. Standalone 3rd generation SPRINT and Syrinx DVL can be joined together for pre-calibrated, interchangeable use, or combined into the compact SPRINT-Nav unit. This integrated solution, optionally including an internal pressure sensor, is suitable for various ROV and survey tasks. The combined unit features depth-rated water blocks for each transducer to protect the internal components and when supplied together typically doesn’t require re-export licensing, simplifying your shipping logistics.

Designed and manufactured entirely in the UK, Syrinx is a class leading DVL for surface and subsea vehicles, available in two frequencies: 600 kHz or 400 kHz for higher altitude tracking up to 230 m. Syrinx variants combine high resolution and high altitude tracking, in single, easy to install navigation instruments. Its adaptive bottom lock technology provides consistency and reliability over challenging and changing topography, working at an altitude higher than 85% of the world’s subsea infrastructure. This reduces the amount of time a vehicle must dive on free inertial.

If your mission requires water profiling, Syrinx’s highly capable ADCP mode enables both navigation and profiling without the need for separate instrument, saving you cost and payload.

When tightly integrated with Sonardyne’s SPRINT INS, unmatched DVL-aided navigation can be achieved. This allows for enhanced performance through optimisation of beam-level data passed between Syrinx and SPRINT to aid velocity prediction and outlier rejection, with positioning able to continue even if one or two DVL beams are unavailable. For the ultimate integration Syrinx and SPRINT are also available as a single combined unit with integral pressure sensor. SPRINT-Nav is one of the smallest inertial DVL instruments available on the market suitable for almost any ROV and survey task.

Syrinx runs an embedded system manager using a web browser, eliminating the need to install dedicated PC software. This allows configuration and testing of Syrinx prior to deployment, control during subsea operations and visualisation of the navigation data.

The hardware and vehicle interfacing are easy to install, set up and use. It’s compatible with DVL/ADCP mounting arrangements from other vendors so you shouldn’t need to modify your subsea vehicles to upgrade to Syrinx. PD0, PD3, PD4, PD6, PD13 telegrams are supported for integration to third party navigation systems.

A 4,000 m rated titanium housing is supplied as standard to meet the requirements of work-class ROVs. 6,000 m and OEM (no housing) versions are also available.

Syrinx’s transducers have been designed, built and tested in-house to provide maximum performance, and can be individually replaced, reducing ownership costs and repair time. The entire array is water blocked meaning that should damage occur to the transducer array, the unit’s electronics are isolated from water ingress.

Echo Observer for Syrinx (EOS)

EOS is a software application for Syrinx and SPRINT-Nav systems which allows ADCP data to be viewed, quality controlled, logged and then exported. This standalone application is compatible with Windows 7 or 10 and requires only modest processing resources.

EOS provides an intuitive interface to Syrinx, allowing the device to be configured over Serial port or Ethernet with a quick setup procedure for ADCP measurements. You can immediately view the profile data and make any necessary adjustments before committing to a long-term deployment.

Once initial data inspection has been completed, EOS provides the link to the onward data processing chain: Industry-standard PD0 data can be exported as comma-separated variable (CSV) files, ideal for importing into Excel or Matlab for analysis and post-processing. The exported PD0 data can be tailored to match your analysis needs, such as specific portions of the water column, or a favoured frame of reference.

Specific sections of the PD0 data can be omitted in CSV export if they are not relevant to your analysis, reducing file size and therefore processing time. Echo Observer for Syrinx is included with the ADCP functionality upgrade for both Syrinx and SPRINT-Nav.
