1. Autonomous Maritime Systems (AMS)

Chair: Hanu Singh
email: ha.singh@northeastern.edu

Keywords: Autonomous, Unmanned Vehicles, Maritime Systems, Navigation, Sub Surface 

Scope: The technology of AMS vehicles includes flight, surface and subsurface assemblies that are comprised of various sub-systems and instruments. These include flight systems, navigation components, acoustics, propulsion systems, actuators, batteries, vision systems and computational assets for controls as well as data analysis with the outcome of data products. These various technologies are also implemented in a variety of ways beyond single purpose systems with vertical and horizontal multi-asset deployments working in an integrated fashion. An AMS implementation is frequently used in military applications for security purposes, such as harbors and so forth as well as for battle space preparations. Some systems are used in battle also. Other applications include marine science of all types such as to mid-water biology, mapping, chemical sensing, sampling and persistence applications. Industry is expanding rapidly into AMS vehicles with particular attention to oil field inspection and recently intervention tasks. The committee is active in a variety of ways with a focus on a single track symposium held every other year and rotated around the globe in service to our international membership. Along with these meetings the committee supports Special Issues of the OES Journal of Ocean Engineering. The committee is also playing a key role in AMS education by sponsoring student poster competitions for Masters and PhD students as well as supporting and judging at AMS competitions around the world, with OES frequently taking the top spot as the Sponsor. 

 

2. Current, Wave, Turbulence Measurement and Applications

Chair: Hugh Roarty
email: hroarty@marine.rutgers.edu

Keywords: Currents, Waves, Turbulence, Hydrodynamics, Oceanography

Scope: The Current, Wave, Turbulence Measurement and Applications Technology Committee is concerned with methods of measuring dynamic physical parameters of the oceans and applying them to solving problems for society.  The technologies used include sensors for physical, chemical and biological oceanography, and include in situ instruments as well as land-based or water-based remote sensing.  Understanding of fluid dynamics requires fast, small, precise, non-invasive probes, and any applications require high spatial and temporal resolution.   These technologies represent a continuation of the development of direct sensors but other techniques like correlation sonar and drifting floats offer alternatives.  Survivability of sensors remains an issue, particularly in harbors and where fishing is intense on the shelf.  

Interests of the technology committee are in developing and validating instruments for measurement as well as in applications in oceanography and environmental impacts.  Observations and related data analytics are required for studies of the general circulation; pollution fingerprinting, transport and diffusion; vertical and horizontal profiles of current in harbors and rivers; spatial mapping of currents in estuaries, rivers and dams; boundary layer studies; wave fields; and pollution and hazard management. Knowledge of these parameters leads to improved safety and efficiency in shipping, coastal engineering and management of coastal waters and marine reserves.

CWTMA organises a four-yearly international workshop and provides papers and reviewers for other workshops and symposia.

 

3. Data Analytics, Integration  and Modeling

Chair: Gopu Potty
email: gpotty@uri.edu

Keywords: Data Processing, Modeling, database QC, machine learning, data assimilation

The focus of this Technical Committee encompasses all aspects of data processing including data assimilation, data presentation, database design, filtering, modeling, and analysis.

Keywords: observations, interoperability, environment, sustainability, policy

The Ocean Observation Systems and Environmental Sustainability Technology Committee (“OOSES” TC) facilitates the gathering and interpretation of ocean information for the benefit of humanity. In this, the TC focuses on the interactions between the oceans and society. This includes furthering our understanding of the ocean “environment” and disseminating this understanding to decision-making and policy experts.

The TC facilitates discussions and analyses of issues related to the integration of technologies into observing systems as well as advances in observing systems that support decisions and policy making at international and national levels.  Environmental sustainability concerns (e.g., Sustainable Development Goals: SDGs), ocean resources management, technology innovation and international cooperation are elements supporting decision-making. The analyses and recommendations produced by the TC would be disseminated through multiple means including, for example, oceans conference tracks, dedicated workshops and cooperation with GEO and other international organizations.

 

5. Ocean Remote Sensing

Chair: Rene Garello
email: r.garello@ieee.org

Keywords: sensors, satellite, drones, geophysical monitoring, security

Short and long-term observation and monitoring of the oceans is necessary in order to maintain and increase maritime activity security and sustainable ocean exploitation. In this context there is an ongoing need for better sensors, vehicles and processing for limiting human exposure. Accurate and broad-scope information is necessary to develop optimum enterprises and partnerships. Threats and risks need to be understood and managed.  New technologies and new processing algorithms are relying on better access to data, which is critical when dealing with remote sensing devices. This step is mandatory in any research and development project process and implies techniques, which are difficult to implement as well as expensive.

The interactions of engineers and scientists through our Conferences and Publications creates an assembly of talent that leads to rapid distribution of knowledge and stimulation to develop creative opportunities. The main place to meet and exchange is our flagship Conference, OCEANS. Several IEEE workshops or other conferences include many topics stated in the previous paragraphs and ranging from Earth Observation to AUVs.

 

6. Ocean Sustainable Energy Systems

Chair: Seamus Garvey
email: amus.garvey@nottingham.ac.uk

Keywords:  Offshore wind, Wave energy, Tidal Power, Energy Storage, Floating platforms.

The Ocean Sustainable Energy Systems Technology Committee supports the development and deployment of fully sustainable and affordable systems for harvesting energy offshore, and delivering that energy in appropriate forms for human use. Thus, offshore wind power plant, tidal-range and tidal-stream generation plant, wave energy converters, systems generating electricity from thermal gradients and/or salinity gradients, offshore solar thermal and photovoltaic systems and systems for the offshore farming of algae and other biomass are all within the scope. Coupled with these energy harvesting technologies, the scope necessarily embraces systems for energy storage such as the various forms of offshore pumped-hydro, underwater compressed air storage and storage of synthesised energy vectors as well as systems for power transmission across stretches of the ocean/sea. Integrated systems comprising systems for energy harvesting, storage and transmission are central. 

The scope includes energy-resultants (energy services) as well as energy. As an example, if cooling is required on a Mediterranean island, it may be better to pump cool water from deep in the Mediterranean than to generate electricity offshore and consume that in heat-pumps onshore. Other examples could include offshore data-processing, mineral/metal processing and refinement, and aircraft fuel synthesis.  The OSES Technology Committee partners with the Offshore Energy and Storage Society to run regular workshops and conferences.

 

7. Polar Oceans

Chair: Andreas  Marouchos
email: andreas.marouchos@csiro.au

Keywords: Arctic Ocean, Antarctica, Southern Ocean, extreme conditions

Scope: Research and development in the Arctic and Antarctic regions is dependent on infrastructure that requires long term planning and substantial budgets.  The deployment of engineering and technology solutions in the polar oceans must be adapted to the harsh conditions there.  All science and development goals are subject to weather extremes and remoteness, where even the simplest of measurements need special technology support.  The challenges to monitoring changes in ocean physics and biology, sea ice and ice shelf dynamics need to be met so that we can understand and predict the future of the Earth system.  Commercial operations such as transportation and mineral extraction industries need R & D support to manage the technical and operational challenges. In the Arctic Ocean receding sea ice is opening previously inaccessible sea lanes, which is providing increased commercial opportunities.  The Antarctic region is governed by an international treaty that encourages research and focuses on environmental solutions for the physical systems of ice and water as well as for the unique ecology.  The Polar Oceans TC supports the work addressing these challenges through relevant streams in conferences and the hosting of workshops and symposia. 

 

8. Standards

Chair: Kenneth Foote
email: kfoote@whoi.edu

Keywords:Calibration protocols, quality assurance, best practices, international standards, OES Standards Initiative

Scope: The Standards Committee promotes and participates in the development of standards for use in oceanic engineering.  It conducts a Standards Initiative, which aims to compile and disseminate information on standards, protocols, quality assurance procedures, and best practices that are important in oceanic engineering.  It does this through the OES website, where information and references are given to standards concerning, thus far, oceanographic data, the offshore oil and gas industry, and underwater acoustics.  It sponsors occasional special initiatives, as in the case of the OES Interoperability Standards Initiative for the Marine Environment.  The committee also participates in the formulation of standards by the IEEE Standards Association (IEEE-SA), International Organization for Standardization (ISO), International Electrotechnical Commission (IEC), and American National Standards Institute (ANSI).  It routinely convenes and conducts sessions at OCEANS Conferences, vets publications on standards, and liaises with other TCs.

10.Underwater Acoustics

Chair: Kenneth Foote
email: kfoote@whoi.edu

Keywords: Sonar, bioacoustics, environmental acoustics, hydrography, naval acoustics

Scope: This committee is concerned with the generation, propagation, scattering, and reception of underwater sound, particularly technologies that enable detection, classification, localization, and quantification. Generic devices used for transmission and/or reception include echo sounders, multibeam sonars, sidescan sonars, acoustic-lens-based sonars, parametric sonars, standard sound sources, and hydrophones used singly or in arrays. When calibrated, these active or passive devices enable measurement and quantitative imaging. Operating frequencies span the sub-hertz to low-megahertz range. Traditional applications include hydrography, as in detecting hazards and determining bathymetry for navigation; military, as in anti-submarine warfare and mine countermeasures; and search and discovery, as for uses by law enforcement. Other major applications are bioacoustics, or quantification of fish, zooplankton, marine mammals, and other organisms, both mobile and stationary, as in the case of sea grass; environmental acoustics, or direct measurement and/or inference of hydrographic properties of the water column and material properties of the seafloor and sub-bottom; sediment acoustics, or measurement of the properties of suspended and consolidated sediment; and seismic acoustics, involving measurement of natural vibrations in the earth and imaging of the sub-bottom in geophysical exploration. Industrial applications abound, as in surveying the seafloor for offshore civil engineering projects; detecting natural gas seeps and pipeline leaks; inspecting vessel hulls; inspecting subsea platforms used by the offshore oil and gas industry; surveying routes for cables and pipelines; and monitoring noise produced by offshore industrial activities. The committee routinely convenes and conducts sessions at OCEANS Conferences, and liaises with other TCs.  

11.Underwater Cables and Connectors

Chair: M.A. Atmanand
email: atma@niot.res.in

Keywords: Cables, Optical Fibers, Connectors, Repair and Maintenance

Scope: The technology foci of the Underwater Cables and Connectors Technology Committee are engineering activities and products associated with underwater telecommunications and cables including those that use optical fibers. The fiber optic telecommunications focus subsumes systems, networks, and underwater observatories, including transoceanic and festooned fiber applications, and the revitalization and reuse of first- and second-generation fiber optic technologies for acoustic information and data transfer for scientific ocean engineering.

Also included in the focus are development and use of underwater vehicles for repair, observation, and maintenance of underwater cable technology and associated sub-systems. The connectors focus recognizes that connections to instruments and to one another must sometimes be made underwater, not simply submerged after being assembled in air.  The underwater connector is a highly evolved, relatively expensive component used extensively in ocean engineering.  The connector focus thus involves various materials, their electrical and mechanical properties, long-term integrity in a harsh environment, and operations involving disassembly, sometimes underwater, and the recovery of separated cables and instruments for potential redeployment.  Also included in the focus are seals, marine corrosion, watertight integrity, electrical and optical continuity, and impedance matching, all of which may be critical in such devices.  The committee provides a focal point for technical information exchange and promotes cooperation and coordination among fiber optic component manufacturers, connector manufacturers, and installers serving the telecommunications, ocean science, oil and gas industry, government, and special applications communities.
