New Developments in Offshore Robotics For Certification of Assets
Offshore robotics and artificial intelligence linked to data hold huge potential to revolutionise the way we inspect, repair and maintain our offshore structures. However, current use cases and business models present fundamental interdisciplinary scientific challenges. Once solved, we can realise remote, semi-autonomous systems that will work safely in marine, topside (on asset) and airborne environments.
These research challenges include:
a) mapping and surveying of complex structures using multiple robots equipped with distributed, mobile optical and acoustic spatial sensors and industry accepted non- destructive evaluation (NDE) sensors in the dynamic and challenging off-shore environment,
b) planning and execution of efficient, localisable and repeatable motion, and contact of heterogeneous robotic deployment platforms (wheeled and legged for topside, aerial and marine) for sensor placement and manipulation in extreme and dynamic conditions - with specific emphasis on failure prediction, re-planning and recovery strategies,
c) effective communication of world view, system actions and plan failures between remote robot and operator to develop trust and avoid unnecessary aborts,
d) designing robotic systems that can self-certify and guarantee their safe operation, including when learning systems are involved.
The presentation will review work underway in the UK’s ORCA Hub https://orcahub.org to address these scientific challenges and apply them to industrially defined application use cases from offshore energy.

Power to Progress: Offshore Wind Technology and Market Trends
The global offshore wind market it thriving, with technology and innovation driven from the rapidly expanding European market and a number of global markets in various phases of realizing the potential for offshore wind. This presentation will give an overview of the evolution of offshore wind technology and what the future may look like. Deployment of innovative offshore wind technology is dependent on both physical conditions and market condition; therefore, it is important to understand the context of offshore wind deployment from a market standpoint. This presentation will discuss global market trends, and will also take a deeper dive into the current state of the industry in the U.S.

AUVs and ASVs: Realities of Unmanned Maritime Digitalization
Autonomous Underwater Vehicles (AUVs) and Autonomous Surface Vehicles (ASVs) have been robustly under development for more than 30 years. Many versions have already been fielded and have provided some of the anticipated advantages. The applications, while starting simple, are morphing to the more complex. Engineering, including autonomy and reliability, continue to be a challenge as the young technology matures. This talk will discuss various types of AUVs and ASVs, the associated advantages and limitations, current and future applications, operational approaches, engineering challenges, commercial aspects, as well as lessons learned.
Presenter: Thomas S. Chance
Marine Technology Entrepreneur
Former CEO, C & C Technologies and ASV Global (Retired)
Thomas Chance is a marine technology entrepreneur. He founded C & C Technologies out of his home in 1992. C & C became a global oil field surveying and mapping company with 600 employees in ten offices worldwide. C & C was the first company in the world to offer autonomous underwater vehicle (AUV) survey services to the oil industry. The company developed extensive AUV technology, executed more than a half-million kilometers of AUV survey lines, and remains a world leader in the field. In 2015, Mr. Chance sold C & C Technologies to Oceaneering International.
Complementing the autonomous underwater vehicle business, Mr. Chance started ASV Global LLC in 2010. ASV had 170 employees, offices in the US and Europe, and had built more than 100 state-of-the-art autonomous surface vehicles (unmanned boats) for the defense and commercial sectors. In addition to selling unmanned vessels, the company leased unmanned vessels, integrated a variety of payloads into the vessels, and assisted clients with their unmanned programs. Mr. Chance sold ASV Global in 2018 to L3 Harris where he remained until his retirement in June 2019.
Mr. Chance's experience with both the development and field operations of AUVs as well as ASVs gives him a unique, overarching, and real world perspective of these technologies.
Mr. Chance has a BS in Electrical Engineering from LSU, an MS in Engineering from Purdue, and an MS in Industrial Administration also from Purdue.

Application of control system science to wave energy harvesting
Optimising energy capture for wave energy devices is complex, owing to the reciprocating nature of the energy flux, variation in wave height and period, and the non-causality of the optimisation problem. Techniques from the control system sciences can be useful in many aspects of wave energy device optimisation, including energy maximising control, estimation of unmeasureable hydrodynamic excitation force, wave and force forecasting, data-based model determination, and parametric fitting of requisite hydrodynamic parameters. The lecture will explore these techniques and illustrate their use through some application examples.

A NO-BLADE, NO-ROTOR, CURRENT ENERGY CONVERTER (of friendly vortices and instabilities)
Horizontal marine hydrokinetic energy is clean, renewable, abundant and worldwide available in ocean currents, tides and rivers. For a hydrokinetic turbine (HKT) to become part of a sustainable energy future, environmental, economic and social issues need to be addressed. Those result in numerous harvesting challenges in addition to low power-to-volume density of renewables, a vast resource of currents slower than 2-3kn, and high deployment/retrieval/maintenance cost.
HKT challenges are discussed as addressed by the VIVACE converter, introduced at OMAE2006. It utilizes four fish-school biomimetic principles: alternating lift in VIV and galloping, enhancing instabilities, multi-cylinder synergistic FIO, and adaptive damping. Extensive lab and field testing, recent accurate modeling of FIO motion and forces, shape variation, and nonlinear oscillators result in a three-dimensional converter, with open-ended response amplitude operator, efficiency up to 88% of the Betz limit and power density of 600W/m3 at 1.26m/s (equivalent to 12m/s in air, where wind farms reach 0.01W/m3).
