OFG CEO Matthew Kowalczyk, will be presenting: Controlled source electromagnetic mapping of massive sulfide deposits with an AUV
OFG in collaboration with Fukada Salvage and Marine Co. Ltd. and the Scripps EM Laboratory has developed and demonstrated an AUV Controlled Source Electromagnetic (AUV-CSEM) system for the mapping of seafloor massive sulfides. The system can equally be deployed in the mapping of resistive subsurface bodies such as gas hydrates. The economic and operational advantages that the AUV CSEM system presents through the concurrent acquisition of magnetic, CSEM, water chemistry, SBP, SSS and MBES data from a single AUV in a single pass are clear. Results of the initial tests and development work along with the 3D earth model created from AUV data acquired during the AUV CSEM mapping campaign following the test program will be presented
Looking forward to seeing you there. UMC Sept 24 – 29, Berlin, Germany.

The Self-Compensating Magnetometer (SCM) System – Test Results from a Remus 600 AUV Survey in Yellowstone Lake
Panel Session: Unmanned Vehicles and Vessels - Innovations in Autonomy
Location: Conference Room 26B
Date and Time: Wednesday Feb 15th from 16:00 - 17:30
In 2016, Ocean Floor Geophysics (OFG) released a new Self-Compensating Magnetometer (SCM) system to the subsea industry. This magnetometer was designed specifically for use in autonomous underwater vehicles (AUVs) and some remotely-operated underwater vehicles (ROVs). Using data collected during a calibration maneuver, correction coefficients are calculated for the magnetization of the AUV itself, its attitude in the Earth’s magnetic field, and for variable electro-magnetic effects related to the power drawn by the vehicle’s propulsion and maneuvering system. This compensation algorithm eliminates the need to tow the magnetometer or degauss the vehicle to collect useful magnetic data.
Collecting data with a magnetometer mounted inside or on an underwater vehicle enables the production of much higher resolution magnetic maps than those produced using a surface vessel. Using the SCM, magnetic data can be collected concurrently with high resolution multibeam, side scan, and/or sub-bottom data enabling the interpretation of geology on a local scale instead of a regional one.
As part of product testing, OFG has deployed the SCM on vehicles by various AUV manufacturers. We discuss here the data from a magnetometer deployed on Remus 600 AUV doing a multibeam mapping project in Yellowstone Lake. Magnetic data was collected over four dives and compensation was applied to the raw data using the SCM algorithm. Maps were generated and compared with historical magnetic data collected using airborne techniques. The comparison shows that the data collected using the OFG SCM is consistent with the airborne results but provides significantly more detail, revealing features that were not visible in the airborne data. These local features can provide useful and detailed geological data that compliments the precision bathymetry collected by the AUV.
OFG has received an order for a 6000m depth rated Self-Compensating Magnetometer (SCM) for integration into an Explorer AUV. The ISE Explorer class AUV is a well tested and proven platform for the OFG SCM system, as the system was originally developed and tested on the 3000m depth rated ISE Explorer "Deep1".
OFG Self-Compensating Magnetometers (SCM) for AUVs continue to gain popularity with 6 systems sold to Kongsberg Maritime for undisclosed clients. In addition to the new SCMs for Kongsberg Maritime, OFG has shipped several systems for light logistics AUVs in the last few months including installations on the popular Remus and IVER systems.
An OFG SCM was deployed on the Hugin AUV used by NTNU in their summer 2016 MarMine seafloor massive sulphide (SMS) research project. We look forward to continued collaboration on subsea magnetic and electromagnetic systems in support of the NTNU MarMine project for seafloor minerals exploration and research.

HiSAS-equipped survey and pipeline inspection Hugin AUV Chercheur added to OFG fleet
Burnaby, BC, Canada - October, 2016
Building on OFG’s strengths in deep water Autonomous Underwater Vehicle (AUV) operations and support services, OFG has invested in a 3000m-rated Hugin AUV. The AUV Chercheur is equipped with an unsurpassed sensor and software suite for extremely efficient inspection of pipelines and infrastructure, pipeline route studies, site geohazard surveys, environmental monitoring surveys, and other seafloor-based applications such as UXO, archeology, salvage, and minerals exploration.
Chercheur is equipped with state of the art high resolution interferometric synthetic aperture sonar (HiSAS), the latest in technology multibeam echosounder EM2040, a sub-bottom profiler, a comprehensive environmental geochemical sensing suite, a high resolution still photography camera, and an OFG Self-Compensating Magnetometer (SCM) system. Chercheur is the most advanced subsea survey platform, and comes complete with all ancillary sensors to guarantee precision navigation and positioning.
OFG’s CTO Peter Kowalczyk commented, “When considering this investment, we felt that synthetic aperture sonar (SAS) is the technology by which other sonar imagery will be measured in the future and that it was a requirement for any new AUV purchase. The incredible imagery produced by the HiSAS system confirms this.”
The combination of Chercheur’s technology, OFG’s experienced AUV operations team, and the expertise of our technology and commercial partners extends the possibility to unveil seafloor properties and characteristics to new levels of resolution and detection.
Included in that extended reach, OFG offers with Chercheur its AUV services for very shallow water operations allowed by the advanced navigation and positioning systems, and the efficient coverage of large areas by the HiSAS system even in shallow water. Detailed camera surveys are also possible in water depths ranging from 10m to 3000m with the EM2040-aided acoustic tracking and following capabilities.
The incredible high resolution imagery produced by the HiSAS system gives offshore oil and gas companies the ability to build and maintain a precise GIS database of the positions and conditions of their seafloor assets, natural features, marine archeology inventories, UXOs and other features of interest such as plumes. Seafloor minerals exploration teams will also benefit greatly with regards to geological interpretation.
OFG looks forward to supporting our clients and commercial and technology partners with the deployment of this portable, self-contained AUV survey and inspection system around the world.

Applications for established deep sea geophysical methods used in mineral exploration for the subsea inspection of pipeline infrastructure
Peter Kowalczyk, Chief Technical Officer, Ocean Floor Geophysics Inc.
As subsea pipeline are placed in deeper and deeper waters and the installed infrastructure ages, the necessity to inspect these pipes efficiently is becoming urgent. Present methods rely upon visual inspection using remotely operated vehicles (ROVs) and intervention using these same ROVs. This is costly, and these costs are increasing as inspection requirements become more stringent and the depth of water that the pipelines sit in also increases.
Autonomous Underwater Vehicles (AUVs) can dramatically lower the cost of routine inspections and allow timely and appropriate intervention. This strategy of using AUVs to inspect on a regular basis, followed by targeted interventions at problem areas using ROVs will result in lower costs overall, with a higher success ratio at interventions due to the early recognition of problems and an outcome of reduced adverse environmental impacts. The OFG AUV "Chercheur" is an fully equipped survey and pipeline inspection AUV with an unsurpassed suite of sensors including HiSAS (Synthetic Aperture Sonar), EM2040 multibeam echo-sounder, high resolution camera and on-board pipeline tracking software. These systems can be used to map as-built positions, buckling, movement, supports, mat positions, scours and free spans. There exists an opportunity to further extend the capabilities offered by Chercheur for the detection of invisible flaws such as cracking, pipeline erosion and corrosion (internal and external), and fractures through the use of technologies proven in the arena of subsea minerals.
Three technologies have particular application and can be readily adapted to use in AUV pipeline inspections. These are E-field monitoring of galvanic protection systems, magnetic monitoring of impressed current cathodic protection (ICCP) systems and the measurement of the electromagnetic time decay constant of the pipe itself using a time domain electromagnetic (TEM) system. (1) E-field monitoring implies measurement of the ambient electric field around a pipe using detection electrodes on an AUV. The electric gradient in seawater is a measure of the cathodic current flowing from the pipeline, and the activity of active or passive cathodic protection electrodes. Anomalous reading will indicate a failure in the pipeline covering, or wastage of the cathodic electrodes. (2) Magnetic measurements along the pipeline made with high frequency magnetometers can measure the amplitude of the cathodic protection current in the pipeline for ICCP systems. If the current along the pipeline changes, this indicates leakage of current from the pipeline to the sea. A correlating E-field anomaly may be expected at this location. (3) TEM measurements will require a transmitter on the AUV, and then an appropriate high speed and very sensitive vector magnetometer to measure the secondary field from the induced secondary current in the pipeline caused by the TEM transmitter pulse. The measurement of the time decay constant (tau) is important as this is a property of the pipe, and is independent of the transmitter and receiver geometry. A change in tau will indicate a change in the physical condition of the pipe. In particular, a reduced tau can be expected to correlate with damaged regions of the pipe.
All three methods are used in subsea mineral exploration, and equipment to make these measurements has been developed and is proven to work in the subsea environment. The technology risk here is small, and the challenge is to demonstrate these technologies from the subsea mineral exploration world in the world of industrial subsea pipeline inspections.

A Self-Compensating Magnetometer (SCM) System for High-Resolution Mapping on AUVs
Ocean Floor Geophysics Inc.
In June this year OFG released a new Self-Compensating Magnetometer (SCM) system, designed specifically for AUVs, to the subsea industry. In 2014, Ocean Floor Geophysics developed a method to compensate raw survey magnetic data collected inside an the AUV using data collected during a calibration maneuver prior to the survey. Correction coefficients were calculated from the calibration maneuver data to account for the magnetization of the AUV itself, its motion through the Earth’s magnetic field, and for variable currents related to the AUV’s propulsion and maneuvering. The process was not automatic and required operator supervision at all stages.
This has led to the further development to the only Self-Compensating Magnetometer (SCM) system on the market. The system is a combination subsea magnetometer sensor (up to 6000m rated), a processor/data logger, mechanical calibration procedure, and a proprietary software algorithm that computes a series of correction coefficients and applies them to calculate compensated and corrected magnetic data in real time.
Potential high-resolution mapping applications for this system that require the use of AUVs include geologic mapping, engineering applications for pipeline and cable mapping and tracking, mine countermeasures, mapping of unexploded ordinance (UXO), and archeological applications for mapping ship wrecks. Examples of maps of the compensated magnetic data that were collected on surveys for some of these various applications will be shown.
Initial tests of an AUV-borne controlled source electromagnetic (CSEM) system

Controlled source electromagnetic systems (CSEM) are used to map subsurface resistivity structure. In 2014 and 2015, OFG used a towed CSEM system developed by the Scripps Institution of Oceanography to map gas hydrate deposits to depths of several 100 metres below the seafloor. We would like to be able to perform CSEM surveys over submarine massive sulfide (SMS) deposits. However, towing the system at a constant depth in terrain with steep bathymetric gradients, such as in the vicinity of hydrothermal chimneys associated with SMS deposits, would prove difficult. Other difficulties with a towed system include requiring a large ship to deploy and power the system, and long, time consuming, turns for high resolution surveys with tight line spacing because the receivers extend well behind the ship.
A novel approach to overcome these difficulties would be to mount electrodes on an AUV with the transmitter towed in the ocean by a ship or emplaced on the seafloor. It would require a smaller ship to launch an AUV than to launch and power a long source/receiver array, and the AUV is capable of tight turns, saving ship time when little useful data is collected. In addition to deployment considerations, the largest potential benefit is the ability to simultaneously collect high-resolution multibeam, sidescan, subbottom profiler, magnetometer, and chemical sensor data.
The largest uncertainty regarding an AUV-borne CSEM system is whether the signal (of the received electric field) to noise (related to the vehicle propulsion plus payload) ratio is sufficiently high. OFG, Scripps, and Fukada Salvage and Marine Works Co. Ltd. (Fukada) devised an experiment was to record the ambient electric field noise on CSEM electrodes mounted to an operating AUV graciously provided by Fukada. A series of tests were designed and run to investigate how the ambient noise levels on the electrodes changed with the vehicle operating while (1) turning off the payload devices one by one; (2) varying the heading of the vehicle; and (3) varying the speed of the vehicle. Data were analyzed together by OFG and Scripps and results are presented. As well, EM modelling results using these preliminary test results are presented here to show the sensitivity of the electric field response over typical massive sulfide deposits
OFG announces the release of a new Self-Compensating Magnetometer (SCM) system, designed specifically for AUVs, to the subsea industry.
Burnaby, BC, Canada - May, 2016
The magnetic signature of an AUV varies with heading, attitude, motor currents, and changing payload configurations. Magnetic surveys using AUVs have been undertaken with either specially configured degaussed or magnetically reduced AUV’s or tow magnetic sensors. Both configurations are designed to reduce the magnetic effects of the AUV on the sensor, and require the surveyor to compensate for the effects of heading. Both of these approaches have significant operational challenges and complications, especially if other sensor payloads are required, or if the vehicle is flying at low altitudes through complex terrain or amongst obstacles.
The OFG SCM is a robust, reliable magnetometer system that provides real-time compensated and corrected 3‑component magnetic data. The OFG SCM can be installed inside the hull of the AUV or strapped directly to the outside of the AUV body to minimize operational risk and provide compensated 3‑component magnetic data.
The OFG SCM, with its simple integration, opens up possibilities for AUV operators and AUV systems integrators to use the 3-component magnetic data for both in-mission decisions regarding magnetic anomalies (e.g. UXO, pipe and cable tracking, ship signatures, mine countermeasures) and post-mission maps (e.g. archeology, geology, exploration, environmental and geotechnical projects). This is accomplished without the need for a dedicated magnetic survey AUV or an experienced geophysicist to manually remove all of the magnetic vehicle effects.
The OFG SCM system is a combination of a subsea magnetometer sensor, calibration procedure, and proprietary software algorithm that computes a suite of correction coefficients and applies them to calculate compensated and corrected magnetic data in real-time. The SCM software can run on an existing AUV payload computer or an OFG supplied processor with optional pressure housing. The system is available in both 100m and 6000m depth ratings.
The CEO of OFG, Matthew Kowalczyk, is extremely encouraged by the reception that the new system has received from AUV manufacturers and users. “We are very proud that we have been able to take the post-processing algorithms and technologies, which we have been providing to our commercial AUV survey customers for years, and transform them into a stand-alone real-time sensor for use in AUVs. The SCM will be very useful to anyone operating AUVs in scientific, military and commercial spaces. The OFG SCM system can be seamlessly integrated into any existing AUV, and can acquire magnetic data simultaneously with other standard AUV sensors, such as sidescan, multibeam, cameras and water chemistry. People often choose to forgo magnetic data due to the added operational complexities of towed systems, even though it is complementary and extremely useful when acquired in conjunction with other standard subsea survey sensors. There are many magnetometer technologies available; they cover a spectrum from extremely sensitive but difficult to deploy SQUIDs through to Hall Effect sensors that are simple to deploy but not sensitive enough for survey applications. At the risk of belabouring the point, a towed SQUID magnetometer will likely get you the best magnetic data possible, but the operational challenges of keeping a Dewar flask of liquid nitrogen full underwater precludes this as a practical solution! The OFG SCM system fills a gap in the market and turns any AUV into an excellent magnetic survey platform without the need to degauss the AUV, characterise the AUV’s magnetic signature, tow a magnetometer, or engage experts to back out the heading and attitude errors of the vehicle.”
