11 NAVIGATION AND POSITIONING A unique range of inertial Solutions not affected by GPS outage From shallow water to greater depths USBL systems When surveying under bridges or close to structures, GPS cannot be relied on, satellites get masked entirely, or even worse, reflected off those structures leading to erroneous readings from the GPS receiver. Inertial navigation systems can detect spikes on GPS data and exclude them from the navigation calculation. Positioning noise is reduced whilst position and attitude data is available at up to 200 times per second. Sometimes errors in configuration or particularly prolonged periods of poor aiding data can affect the inertial calculation. In this case, Apps and Delph INS post-processing softwares may be used to re-process the data, optimizing settings, and using advanced techniques to improve on the results that are possible in real time. With Gaps and Posidonia ixblue delivers a complete USBL offer with extensive track record of successful use from very shallow water (50 m) to greater depths ( m). By combining acoustic and inertial technologies fully owned and mastered by the company Gaps offers a unique portable and pre-calibrated USBL solution easily transferable from one vessel to another. Following ixblue philosophy, Gaps and Posidonia are based on an open architecture with serial and Ethernet connectivity and Web control command. All our USBL are compatible with third party equipment. Operating in harsh environments Acoustic data communication With every gyroscope ever built, navigating at high latitudes has been a problem. As the sensor approaches the North or South pole, the problem of detecting the exact direction to the north becomes more and more difficult. ixblue has extensive experience of working at high latitudes with inertial systems. We have developed custom algorithms to deal with the problems of navigating at theses latitudes and continues to develop techniques and algorithms to allow even higher performance. Control/Command your AUV Gaps enables simultaneous tracking and acoustic coms without the need to install a dedicated modem transducer on the AUV or on the surface vessel. You can now track, send commands and receive AUV status, all with the same equipment. Wirelessly send a position to recalibrate an INS in an UUV For AUV and ROV applications, Gaps enables a position to be sent wirelessly to a subsea INS: Gaps estimates the position of the beacon (USBL) Gaps sends its position to the beacon The beacon broadcasts the position Collect data from any subsea sensor Any sensor can be interfaced to a subsea beacon. The beacon broadcasts the measurements to the Gaps through the acoustic channel. Gaps outputs the information on a serial or Ethernet communication port. to the subsea INS 20 MARINE SURVEY MARINE SURVEY 21

21 challenges and solutions ixblue conceives a large range of systems designed to address the full spectrum of subsea imagery applications, from sub-bottom profiling to water column monitoring. Considering that barely 10% of the bottom of the ocean has been mapped with a submetric resolution, imagery and mapping of the seabed can be considered one of the last frontiers of human knowledge. To help all major players in this field to overcome this challenge, ixblue offers innovative solutions to produce correctly positioned and good quality images at low costs, in wide sea conditions and on any type of platforms. The excellence of our sensors, the fusion of their data with navigation and positioning, an efficient and easy to use software suite, allowing the integration of an open and scalable hydrographic suite on all types of platforms This is how we will succeed in mapping the global ocean and optimally managing its resources. Mastering the full chain of acquisition At ixblue we believe that to provide quality data the entire chain of acquisition must be optimized, from the sensor to the platform. That's why we design all our transducers and antennas, power and acquisition electronics, data processing and platforms in-house. This allows us to deliver unparalleled data quality from the water column to the ocean floor. This quality of data is recognized by the world's leading hydrographic and marine research institutes that routinely use our products. Accurate pixel positioning We think that even the highest-resolution and clean data only has little value if not correctly positioned, or if its acquisition is only possible for weather windows that are too sh d know-how in inertial navigation and underwater positioning to integrate these fundamental data into its sonar processing. The pixels produced by our side-scan sonars (SSS) are thus positioned with submetrical accuracies even at a 6000 m depth and in harsh weather conditions, removing all management problems of overlapping lines and contact repositioning. Our sub-bottom profilers are also compensated for heave greatly improving the readability of the profiles. Finally, our 3D multibeam echosounder, SeapiX, is the first gyrostabilized multibeam echosounder in transmission and reception by integrating an inertial motion unit closest to the antennas. Pushing the boundaries of seabed imagery These unique capabilities for data fusion of inertial navigation, acoustic positioning and sonar imaging, allow ixblue to push the boundaries of seabed imagery, by offering the first synthetic aperture sonar, specially designed for hydrography and surveys. Our product line SAMS (Synthetic Aperture Mapping Sonar) thus makes it possible to operate a SAS as one would a standard SSS, while allowing a resolution gain between 5 and 10 depending on the configuration, compared to conventional SSS of the same range, while being operable on any type of platform. These unique sensors, with their intrinsic performance and ability to merge their data, are fully exploited thanks to the Delph software suite that offers a standardized and simplified man-machine interface. It allows acquisition, quality check, processing and visualization of all geophysical sensors: from side-scan sonar, to seismic and magnetometer. Delph has become the reference in the survey industry and its optimization for massively parallel data processing makes it the perfect tool for cross-platform data processing. We also believe that the quality of a hydrographic suite lies as much in its sensors and software as in the quality of their integration. This is why our survey platforms are able to closely integrate all the sensors that meet the needs of the surveyors. These sensors are collocated, synchronized and co-referenced transparently for the user. A third-party friendly technology Finally, at a time when technologies are evolving at a furious pace, where the survey industry is experiencing two major revolutions with automation and big data, we want to design hydrographic suites with the best performance that can be offered today while being capable to integrate future needs. Our systems are thus fully open to the integration of thirdparty sensors and can be integrated on any type of platform: towfish, gondolas, drones or survey vessels. Our offer is an open, coopetitive and comprehensive hydrographic suite. 40 MARINE SURVEY MARINE SURVEY MARINE SURVEY

23 SUB-BOTTOM PROFILERS A complete range of Sub-bottom profilers covering the full spectrum Key benefits A complete solution: More than just a sub-bottom profiler, the Echoes series provides a complete solution for acquiring, processing and interpreting high quality geological data thanks to its integration with the provided Delph Seismic software. Echoes sub-bottom profilers use an acoustic array of transducers that are using the piezoelectric ceramics properties of ceramics in which a high-voltage current is sent. The properties of this signal are reproduced by the emitted acoustic soundwave (Chirp, CW, Ricker, etc.). Thanks to the reciprocal piezoelectric principle, this acoustic array can be used to sense the reflected soundwaves. Having developed Echoes in collaboration with French Marine Institute Ifremer over the course of 20 years ensures used for vertical imaging of sediment layers by the mean of low-frequency acoustic sound-wave reflections. Similar to reflection seismic methods, a fully mastered low-frequency acoustic waveform is emitted, and the receiving of the many reflections that occur when the acoustic impedance changes (air-water, watersediment, sediment-tosediment interfaces). This acquisition sequence is repeated over time when the acquisition system is moving and results in successive scans that build acoustic profile images depicting When using chirps with Echoes, maintaining a very high vertical resolution whatever the power level is made possible thanks to the modulated signal that is mastered over time. While this aperture remains wider than the one of a parametric, it provides superior quality imaging of the sediment layers, especially when the arrangement of acoustic layers becomes complex. It is also naturally more robust to motion. The coupling of a motion sensor is recommended for heave compensation only.

26 SYNTHETIC APERTURE MAPPING SONAR The SAMS series expands the capabilities of conventional imaging SSS By integrating positioning and navigation capabilities and performing real-time coherent and non-coherent SAS integration, ixblue makes SAS technology available to all hydrographic surveyors. The combination of all these technologies gives SAMS systems optimal imaging performance with respect to environmental conditions in terms of swath, resolution, image quality, coverage rate and absolute pixel positioning accuracy. Although the progress made by multibeam echosounders (MBES) for shallow water backscatter imaging should not be overlooked, SSS remains the tool of choice for seabed imagery despite several limitations: Variation of the along-track resolution with range (this range / resolution tradeoff imposes to work at high frequency to optimize the resolution, or to work at low frequency to optimize the coverage), Sensitivity to platform motion (working with a SSS means using beams of very small aperture to get good along track resolution) and Pixel positioning inaccuracy (mosaic doesn t allow precise georeferencing and platform motion compensation). If standard Synthetic Aperture Sonar (SAS), seems the most appropriate system to solve the first limitation, it only partially addresses the other two. ixblue has thus developed a new type of SSS, a Synthetic Aperture Mapping Sonar (SAMS), to solve those issues. SAMS is based on the following 3 features: Fine coupling between acoustic data, inertial navigation and acoustic positioning: it allows focusing on each pixel in the mosaic, avoiding distortion of the projection of the waterfall on the mosaic. Wide aperture in transmission coupled to multi-channel reception and multi-ping integration: this architecture ensures full coverage even on passive platform in bad conditions of navigation. This multi-ping integration capability makes it possible to perform the twofollowing synthetic aperture processings simultaneously and in real time: Non-coherent integration (summation of signal amplitudes): allowing for significant improvement of image quality thanks to signal-to-noise ratio gain and coherent noise reduction. Coherent integration (summation of signal amplitudes and phases): allowing for significant improvement of the resolution. ixblue warrants a SAS gain of a factor of 6 on passive tow-fish. A truly integrated survey platform: SAMS exploits the synchronous acquisition and positioning capabilities of multisensor data to offer a fully integrated survey platform. In addition to positioning systems and SSS, SAMS platforms can embed a Sub-bottom Profiler, a pinger locator and a magnetometer. All of the synchronized sensors and navigation data are processed and displayed in real time in a 3D environment using ixblue s Delph Software. This allows the implementation of data fusion method to improve the survey area analysis.

34 challenges and solutions The increasing needs for maritime surveys worldwide implies to put more sensors into the water. With platforms more relevant than ever, due to budget control matters. Established on a solid and recognized technical background ixblue is innovation-driven, and benefits from ixblue s in-house vertical integration. It provides its customers with a relevant range of safe, cost-efficient and profit making vessels and derivate. Challenges The level of surveys needs at sea has never been higher than it is today. Unsurprisingly, this unprecedented rise results from the growing interest that an ever-increasing and connected world population is paying to the maritime resources. Needs for marine surveys encompasses a number of new applications with economic or regulatory consequences at hand. Extensive submarine cable networks, new maritime trade routes using northern passages, development of adventure cruises, agriculture on the seabed are all but a few examples of the explosion of the survey needs, both in charted and uncharted territory. At ixblue, we have been providing solutions for our customers operating in Marine Works applications for years. We identified a number of guidelines and added a few over time, in order to accompany the current trends and provide our customers with success enabling assets. We consider not only the building phase but also the entire vessel s operational lifespan. We implement from the design phase, solutions which will allow our customers to: Reduce hazards of going at sea; Control operational costs; Make profits. Solutions In order to reach that goal, as shipbuilders, we settled on different technical solutions. The use of composite as our main building material, in order to make lighter and more efficient vessels (weight/power favourable ratio, reduction of vibrations and vessels radiated noise, reduced total cost of ownership over the operational lifespan ); Moulding process and a CNC 5 axis milling machine for designing perfect moulds and make the best of hydrodynamics; Vacuum infusion process to allow a perfect spread of resin and a uniform resilience factor on the whole structure; An innovative approach to fibers use (international patents on fibers beams/ studs to have lighter yet tougher structures); Non osmosis resin system use; Those technical skills and relevant choices were strengthen over the year, leading to a number of international and national sales, as well as world record breaking achievements (vacuum infusion). With that technical background firmly established, we continued on developing the design part. No technical boundaries are accepted within the certification frame (our vessels are IACS certified), and our design office keeps an open mind on each new project, the unique goal being to keep the customer satisfied. The long lasting in-house vertical integration both with our Survey/ Services or our sensors divisions explains why our vessels seldom have any equivalent on the market and why we operate mainly on repeat orders. 66 MARINE SURVEY MARINE SURVEY MARINE SURVEY

35 VESSELS AND DRONES ixblue offers a range of workboats, research vessels, unmanned solutions, as well as derivate such as tailor-made gondolas and hydrographic buoys. ixblue also operates as a third party composite ship parts builder. The already well-known range of forty-footer welcomed a Windfarm daughter craft, the ixwork 40 WF. Designed from the sea-proven deep V-shape hull, it provides an utmost stability at sea and is used for dispatching personal and conducting intervention on site from a mother ship Service Operation Vessel (SOV). An 80 feet range was also born, with the ixcraft 80, a hybrid harbour and coastal marine work support vessel. Interestingly, its hull is made of aluminium. A major add-on was also brought to market at the end of DriX is the first totally unmanned solution with no human references in the design. This offshore-going, 8-meters Autonomous Unmanned Surface Vessel is in our view a game changer on the Geosciences and offshore Energy markets. Thanks to its Launch and Recovery System (LARS), it allows to drastically reduce surveys costs, the use of non-dedicated support vessels, and tremendously enhances existing research vessels by putting extra sensors in the water. 68 MARINE SURVEY MARINE SURVEY 69
